Your XP VM and the device you're testing shouldn't care about the IP address assigned to vmbr1. So you can leave it static or just remove the IP address from vmbr1 entirely. Might save you some time and energy when hooking 'em up!
@@clabretro you only need to set the IP in the bridge if you want to be able to manage your proxmox from the xp machine in this example. It is a greate video. I love your content btw ;)
As people have said, IP doesn't matter. Your bridge is layer 2. You're effectively physically plugging your VM into whichever network you've bridged onto.
I love how straightforward this device is. An equivalent modern device would require a cloud subscription. And an API that lets you access the data only in a way that benefits the manufacturer and not the user.
I had one of these in a small datacenter I worked at. One day I went to go check out an overtemp alert at around 9:30 PM, and had discovered that the outdoor unit on one of the minisplits lit it's self on fire.

That's quite hilarious that you ran into one of those watch dogs. I work for an MSP and one of our clients have an older watchdog 15-PoE that has very old firmware (was like from 2011).

Fantastic video and look forward to see more of this!
When I need to find an IP range of an unknown device I connect to it with a cross-over to a system with a second Nic then tcpdump or run Wireshark. Start a capture then power on the device to see what it asks for. Like an ARP request of its default gateway or other information it will leak out.
Yep. I stopped using the vendor tool to find the IP address and have used that technique, but! Crossover cables are a thing of the past (I may have 1 or 2, 20 years old?). All Ethernet Network ports in the last 15+ years? have auto mdi-x, aka, auto crossover, so a straight patch would work as well.

Oh, One more thing... The external sensors that plug into the RJ11 ports are just Dallas 1-Wire sensors of various types. Im sure the branded sensors are available on ebay, but if not you can build them yourself. Technically i think you can put up to 127 sensors on the bus, but in practice we used far less because of noise problems with the long unshielded cables ... 10-20 works pretty well though. It just uses standard old fashioned POTS telephone splitters.

And it should report the DHCP address (if any), that the devices plugged in is reporting as.

One thing you could try when looking for the IP is to use wireshark and look at any ARP requests coming from the other device. If it has a gateway defined, it will send an ARP request out looking for it.
I was just thinking that a mirrored port on the switch feeding to a wireshark session would tell you almost anything you needed to know about the existing IP configuration of a device.
That assumes it initiates unicast network traffic by itself, if by chance a device just listens passively this won't work. But even if it doesn't hit the gateway there's a decent chance it will send out _some_ traffic even if it's just a broadcast. In this case you'll need to look at all traffic, focusing on ARP alone won't do any good. On the gateway note, the web management on my D-Link switch has some weird half-baked IP implementation which IIRC managed to work even when the gateway was set incorrectly.

Again great videos! I believe they hooked a sensor to the main electric circuit and it will send an alert if they loose main power.. At that time generators will kick in and employees can monitor everything from the UPS management and probably call and ask the price and delivery time of a tank truck full of diesel just in case...
But when mayor electric work was needed and the circuit from the city needed to be cut we never used our 4 big ass generators... We called a mobile "generator-in-a-container" and hooked it to a special huge plug datacenters have near their main electric rooms.. Maybe it was more cost efective and redundancy wise.. (mobile generator+batteries+generators)
Ah! I have a SuperGoose II in my rack which I inherited when we shut down an old server room (I also have a MicroGoose around here somewhere). I wish I'd know you had this, I also have some sensors I'd be happy to send you. I definitely have some water sensors, I think I still have a power sensor and maybe also an external airflow sensor.
I would expect the dry contacts to be straightforward on/off, between C and one of the 3 inputs. you could try a push button to test them. If you get the chance, you could probably add a leak detector (float contact) from a scrap dishwasher - a lot of them have them in the base plate.
6:07 Hey, just wanted to note that when you're swapping PCIe devices you're supposed to totally remove power from the server (not just shut it down). Seems like in this case it wasn't an issue, but in the past I accidentally did it on one of my R720s and the Lifecycle Controller really wasn't happy with me the next time I booted it up. Just something to keep in mind for the future.
Another blast from my IT past. Configured a lot of watchdog environment sensors when I worked for Delta Airlines in the early 2000's. I'm not sure how but would love to get a Westinghouse 1642, which was the green screened terminals you'd see at airports back in the day before we replace with OS/2 and eventually Windows NT4. Based on what I understand, its all serial and in theory could interface with the TTY console of any device with the right settings (dip switches) applied. Hmmm... off to ebay to search.
Nearly every datacenter I've worked in over the last 10 years had either an ITWatchdogs or a Geist environmental monitor device. Still very common to see in the modern datacenter.
Glad to see someone using the keystone couplers! I started using them at home several years ago and sure, they can fail but that has rarely happened. Not having to spend a bunch of time punching down is nice at home. I save the real cabling for work lol
@@clabretrowe never had anything so fancy in our racks back in the day! thanks for this video btw, it prompted me to dig out an identical model from a uk reseller i inherited from a server room clearout during lockdown, and the reset/powerup part finally got me in. now i know for sure 24/7 that my home office is too cold :) shame the snmp and librenms don't get on.
You can have internal network addresses of what you would typically find on the Internet. You just need to configure a network card to be able to talk with the device on the same network. The caveat being that you may not be able to access services on the Internet that uses that exact network.
We've got two of these at work still. They're more reliable than the new fancy building management system. Different brand but the hardware is identical
City power as in voltage? But i'm pretty sure stuff would die well before 20v. and tbh I would want to track power hz as well as voltage as that will give you a lot of info about incoming power conditions.
Actually, if you want to use bridges, you can also use the virtual functions (VF) of the NIC, so you can get something like 8 virtual interfaces and map a VM with a virtual nic from the card
I upgraded my R7910 to a 2 port copper 10g + 2 port 1g nic a while ago, paid quite a bit for it on ebay. The day after I installed it - my network gets hit by lighting. Only casualty was the 10g card and the switch. Back to the quad 1g nic ever since. Guess it wasn't meant to be.
The universe is telling you to use fiber. AFAIK it's often cheaper than copper and more future resistant, I can't imagine getting over 10G on reasonable copper cables but a cheap fiber cable will be more than good enough for 400G.
that was plan b, but when pulling the preterminated fiber (over 300ft underground in a conduit) I broke the connector during the last few inches pulling it into the rack. @@eDoc2020
@@jfarre20 If you have 300ft of run between buildings then you should _definitely_ be using fiber instead of copper. Any defect in copper for at that distance will result in problems running at high bitrates, and you've already learned what can happen when outdoor runs are copper.
Those dry contact sensors should be really easy to replicate... It's literally just detecting a very small current, usually something like 20mA (you'd have to find out the exact current). You should be able to find some that are compatible or play around with making your own. Oh, BTW, I bet city power was just their Mains power coming in. Dry contact sensors are often used to detect power conditions and are commonly used in UPS devices, so it might have been tied to that.
Another great video this week man. Todays bad idea, more building upon your previous videos Instead of pulling cable you have a great reason to spend time playing with some crusty ancient Cisco trunking to see if you can vlan from your bench to your VM’s. I love vlans, I have a couple WiFi routers sprinkled around my house that bridge ports between them on different vlans so I can link up some legacy Ethernet only hardware to my network or even just to each other.
Fantastic video! I've actually deployed I guess what would be the newer version of the watchdog. Still rack mounted but it has gotten a few quality of life updates, like being POE powered if you like. Wonderful devices, I've debated about throwing one in my personal rack.
If I have a device with an unknown IP, I usually connect it to a PC with running Wireshark or tcpdump. Then reboot the device. Many devices will do at boot a: gratuitous ARP, ARP to the gateway, NTP request, SNMP trap, etc. And from all of them (and any other IP-Header) you can get the IP of the device, no router required. I’m also not sure what the Unifi does to show the IP, I assume they also only listen for a ARP requests.
I just use an old fortigate firewall (well, a few years old, I've been running them for many years and as one lot nears eol they get cheap and that's what I run until the next gen gets cheap). A bunch of the ports are separate zones, each with a dhcp server running. Last device I needed to work out, just plugged into one of these ports, "diagnostic sniffer packet ", and thankfully it broadcast it's ip in the first packet it put out after powerup. Set the interface to that config, and ospf let every other network device on my network know how to get there. Gave it a quick nmap and all was good. It's even easier if the device itself is set to use dhcp, but unfortunately not every old piece of gear comes that way after decommission :(
I don't have much proxmox experience--do you even need to change the IP of the bridge interface in Proxmox, if you're giving the VM itself an IP too? Isn't the bridge just doing a physical layer 2 bridge anyway?

Great video! really enjoyed it :) will there gonna be a video on the Linksys tower of power? im really intressted in them, but dont know much/where to look.
When I have to figure out a random IP, I'll usually use Wireshark and a USB-Nic. Should be able to use it on XP VM? It doesn't actually need an IP.. at minimum you should see the device trying to contact its default gateway or DNS or NTP or request DHCP? Also, for your XP interface you use for IP discovery, turn off the other services (like file/printer sharing. Etc...) to reduce extra distracting traffic...
I used one of the yellow units you showed early in the video many years ago. Worked fine until it started locking up. 😢 Amazingly, not useful for monitoring the server room temperature when it was inaccessible. 😂
Grew up there, in CO now ha. If you want you can shoot me an email anyway, it's in the channel's about page (might have to be on desktop to see it). Maybe we can figure something out.
Pinging 255.255.255.255 is a quick and dirty way to get the IP address of anything on your LAN, unless the device is configured not to respond to pings to that broadcast address. The CLI will usually only show the first address that responded, so IIRC you have to look at the ARP table or have a pcap running on the interface to see the rest of the devices.
14:25 this is always the story with old hardware. I mean there is gazillion memes about that: 20 year old video, 10 year old comment, 5 year old reply. Classic. The best is when you don't even need to tailor the answer to your case - it just matches exactly.
that weather goose turned out to be cooler than I thought-the backdoor password would totally NOT fly in 2024 security always kind of funny to see how "security" was back in the day lol. you might be stuck replacing the riser card for your R720 to fix the intrusion switch issue. unless you can find the wires in that and basically tie it together so it thinks its always closed. Also. Pro Dell poweredge tip, Dell servers like you visiting the lifecycle controller so it can "add to inventory" that's a dell-branded card once you do that it may show up (the 10GB card) in idrac for monitoring...also that can tell the server to re-adjust its fan speed profile for that new card. not required, but a good idea Unless you have CSIOR enabled ( collect system inventory on reboot)
I think you kann make the vm vlan aware (i know that you can do it with a lxc container) and than you can put the vm an a vlan and assign a port to the vlan. But im not 100% sure if this idea is going to work.
You dont Need to add an IP to an Bridge. The ip is only needed if you want to Access the Proxmox Webinterface from the Bridge Network. Just let it empty if you just want to pass a nic. Then you just Need to configure the ip in the vm
you're slowly accruing equipment of similar vintage and in this case exact manufacturer and model to the rack I managed at my last job. you just need a bunch of iBoot stuff and a Dell Precision rackmount server running Cacti.
funny to think that a microcontroller can do exactly that, and probably faster. imagine an esp32 and an sd card and some io. how technology moves! btw, what's inside this goose device? I wanted to see a teardown!
Your XP VM and the device you're testing shouldn't care about the IP address assigned to vmbr1.
So you can leave it static or just remove the IP address from vmbr1 entirely. Might save you some time and energy when hooking 'em up!
ah thank you! I was wondering about that
@@clabretro you only need to set the IP in the bridge if you want to be able to manage your proxmox from the xp machine in this example. It is a greate video. I love your content btw ;)
Came here to say just this. No need to tell proxmox the IP on the bridge for that network at all.
As people have said, IP doesn't matter. Your bridge is layer 2. You're effectively physically plugging your VM into whichever network you've bridged onto.
It's even better for the network security to not give pve an IP on that bridge. Then the old hardware cannot mess around with pve.

@@JZB-2022 I have a Cisco 7912 which when shipped only supported a proprietary but I was able to find a SIP-compatible firmware which works with modern VoIP software. I imagine the ISR would support the proprietary protocol of the original firmware no problem.
another good video. Love that you explain everything as you go on.
thanks!
Hope you keep this in the rack!! Also, looking further to see an update on the homelab tour in 2024!!
I might have to do one of those again ha
Again great videos! I believe they hooked a sensor to the main electric circuit and it will send an alert if they loose main power.. At that time generators will kick in and employees can monitor everything from the UPS management and probably call and ask the price and delivery time of a tank truck full of diesel just in case...
But when mayor electric work was needed and the circuit from the city needed to be cut we never used our 4 big ass generators... We called a mobile "generator-in-a-container" and hooked it to a special huge plug datacenters have near their main electric rooms.. Maybe it was more cost efective and redundancy wise.. (mobile generator+batteries+generators)
Just great! I love this kind of YT videos!
thank you!
We use these in a few of the datacenters I manage.
nice!
If Vertiv bought them, don't be surprised if new sensors are still compatible with the old monitor hardware..
That's good to hear. Is Vertiv a good company? I hadn't heard of them before.
@@clabretro they are / were also known as Liebert. One of the big players in the power / "physical" IT space, along with APC / Schneider.
Ah! I have a SuperGoose II in my rack which I inherited when we shut down an old server room (I also have a MicroGoose around here somewhere). I wish I'd know you had this, I also have some sensors I'd be happy to send you. I definitely have some water sensors, I think I still have a power sensor and maybe also an external airflow sensor.
Oh awesome! Feel free to reach out to the email in the channel's about page (might have to be on desktop to see it).
do it!
@@clabretro Will do. I need to find the sensors then I'll shoot you an email.
I FINALLY found them! Sending an email now.
I use Vertiv's gear daily and they make excellent KVM's. Their environment sensor leave much to be desired, but their KVM's are pretty nice
That was Avocent before they are acquired by Vertiv.
@@markarca6360 Doesn't change the fact I still use them too lol
That netdiscover tool is so cool! Installing it rn
I would expect the dry contacts to be straightforward on/off, between C and one of the 3 inputs. you could try a push button to test them. If you get the chance, you could probably add a leak detector (float contact) from a scrap dishwasher - a lot of them have them in the base plate.
We have one of these in our rack, it’s old but it works! 😂
I can't blame you, this thing works great! haha
What a cool little device. I loved the reset password hack, so brute-forceable 😇
6:07 Hey, just wanted to note that when you're swapping PCIe devices you're supposed to totally remove power from the server (not just shut it down). Seems like in this case it wasn't an issue, but in the past I accidentally did it on one of my R720s and the Lifecycle Controller really wasn't happy with me the next time I booted it up. Just something to keep in mind for the future.
oh yeah really good call out! I got lucky this time, I noticed that while editing. definitely should've pulled the power.
Another blast from my IT past. Configured a lot of watchdog environment sensors when I worked for Delta Airlines in the early 2000's. I'm not sure how but would love to get a Westinghouse 1642, which was the green screened terminals you'd see at airports back in the day before we replace with OS/2 and eventually Windows NT4. Based on what I understand, its all serial and in theory could interface with the TTY console of any device with the right settings (dip switches) applied. Hmmm... off to ebay to search.
ha thats cool. and yeah one of those terminals would be awesome
Nearly every datacenter I've worked in over the last 10 years had either an ITWatchdogs or a Geist environmental monitor device. Still very common to see in the modern datacenter.
Glad to see someone using the keystone couplers! I started using them at home several years ago and sure, they can fail but that has rarely happened. Not having to spend a bunch of time punching down is nice at home. I save the real cabling for work lol
only way to go! so much easier, especially when you're making changes.
that's so crazy to see a bit of atkins infra, i worked for ws atkins in frontline support and later as a consultant from '96-'01 in the uk
ha awesome!
@@clabretrowe never had anything so fancy in our racks back in the day! thanks for this video btw, it prompted me to dig out an identical model from a uk reseller i inherited from a server room clearout during lockdown, and the reset/powerup part finally got me in. now i know for sure 24/7 that my home office is too cold :) shame the snmp and librenms don't get on.
I would personally love to see a video of you installing and setting up a SNMP server.
I'll probably get that in a future video!
You can have internal network addresses of what you would typically find on the Internet. You just need to configure a network card to be able to talk with the device on the same network. The caveat being that you may not be able to access services on the Internet that uses that exact network.
I love that you found that reset info in an old youtube comment xD
You don't have to edit the bridge in PVE. You can remove the IP on vmbr1 and it will still work inside your vm.
We've got two of these at work still. They're more reliable than the new fancy building management system.
Different brand but the hardware is identical
City power as in voltage? But i'm pretty sure stuff would die well before 20v. and tbh I would want to track power hz as well as voltage as that will give you a lot of info about incoming power conditions.
digi makes a lot of things like that, serial to ip, usb to ip, etc.
Actually, if you want to use bridges, you can also use the virtual functions (VF) of the NIC, so you can get something like 8 virtual interfaces and map a VM with a virtual nic from the card
I upgraded my R7910 to a 2 port copper 10g + 2 port 1g nic a while ago, paid quite a bit for it on ebay.
The day after I installed it - my network gets hit by lighting. Only casualty was the 10g card and the switch. Back to the quad 1g nic ever since. Guess it wasn't meant to be.
That's a sad tale haha.
The universe is telling you to use fiber. AFAIK it's often cheaper than copper and more future resistant, I can't imagine getting over 10G on reasonable copper cables but a cheap fiber cable will be more than good enough for 400G.
that was plan b, but when pulling the preterminated fiber (over 300ft underground in a conduit) I broke the connector during the last few inches pulling it into the rack. @@eDoc2020
@@jfarre20 If you have 300ft of run between buildings then you should _definitely_ be using fiber instead of copper. Any defect in copper for at that distance will result in problems running at high bitrates, and you've already learned what can happen when outdoor runs are copper.
Those dry contact sensors should be really easy to replicate... It's literally just detecting a very small current, usually something like 20mA (you'd have to find out the exact current).
You should be able to find some that are compatible or play around with making your own.
Oh, BTW, I bet city power was just their Mains power coming in. Dry contact sensors are often used to detect power conditions and are commonly used in UPS devices, so it might have been tied to that.
Another great video this week man.
Todays bad idea, more building upon your previous videos Instead of pulling cable you have a great reason to spend time playing with some crusty ancient Cisco trunking to see if you can vlan from your bench to your VM’s.
I love vlans, I have a couple WiFi routers sprinkled around my house that bridge ports between them on different vlans so I can link up some legacy Ethernet only hardware to my network or even just to each other.
thank you! and oh yeah we'll be bringing more Cisco relics into the mix for sure
Fantastic video!
I've actually deployed I guess what would be the newer version of the watchdog. Still rack mounted but it has gotten a few quality of life updates, like being POE powered if you like. Wonderful devices, I've debated about throwing one in my personal rack.
Don’t throw it in there, put it in gently 😅 want to keep the lid switch!
The one and ONLY time that UA-cam comments were helpful 😂😂
Nice OCP port usage dell.
If I have a device with an unknown IP, I usually connect it to a PC with running Wireshark or tcpdump. Then reboot the device. Many devices will do at boot a: gratuitous ARP, ARP to the gateway, NTP request, SNMP trap, etc. And from all of them (and any other IP-Header) you can get the IP of the device, no router required.
I’m also not sure what the Unifi does to show the IP, I assume they also only listen for a ARP requests.
yeah think I'll brush up on my Wireshark skills
I just use an old fortigate firewall (well, a few years old, I've been running them for many years and as one lot nears eol they get cheap and that's what I run until the next gen gets cheap). A bunch of the ports are separate zones, each with a dhcp server running. Last device I needed to work out, just plugged into one of these ports, "diagnostic sniffer packet ", and thankfully it broadcast it's ip in the first packet it put out after powerup. Set the interface to that config, and ospf let every other network device on my network know how to get there. Gave it a quick nmap and all was good.
It's even easier if the device itself is set to use dhcp, but unfortunately not every old piece of gear comes that way after decommission :(
That's a really nice way to go, I think I'll end up doing something really similar!
Where did that smoke come from at 3:56 ???
You can run wireshark, it will send arp
I don't have much proxmox experience--do you even need to change the IP of the bridge interface in Proxmox, if you're giving the VM itself an IP too? Isn't the bridge just doing a physical layer 2 bridge anyway?
you're 100% right, I didn't realize that when I was setting everything up haha
Atkins changed name - they are now known as AtkinsRéalis.
They had a fairly large railway design presence in northern europe which they sold to french Systra.
@21:15 if it is on the physical wire cant you find it with Wireshark? I seem to remember doing this is my lab for similar.....I think.
yeah I think that's what it'll iterate to, Wireshark will probably solve all my problems here haha
@@clabretro I really prefer you method as it is much more complicated and as an IT guy that appeals to me. I enjoy finding solutions to problems that don't exist.
Wooohoooo 🎉🎉🎉🎉
Great video! really enjoyed it :)
will there gonna be a video on the Linksys tower of power? im really intressted in them, but dont know much/where to look.
I have one here! ua-cam.com/video/LvLPz72IvAM/v-deo.html. The tower just seems to keep growing, though.
Ah! thank you i mustve missed it! something something tower of babel but networking heh
When I have to figure out a random IP, I'll usually use Wireshark and a USB-Nic. Should be able to use it on XP VM? It doesn't actually need an IP.. at minimum you should see the device trying to contact its default gateway or DNS or NTP or request DHCP?
Also, for your XP interface you use for IP discovery, turn off the other services (like file/printer sharing. Etc...) to reduce extra distracting traffic...
looks like a Rukus logo
I feel bad for just retiring my data centers 720s 😅
Oh, God that pearl 5 book looming in the background
gotta keep it at a safe distance
I used one of the yellow units you showed early in the video many years ago. Worked fine until it started locking up. 😢 Amazingly, not useful for monitoring the server room temperature when it was inaccessible. 😂
You can just leave the bridge config empty on proxmox besides the bridged port. Then you only need to reconfigure xp.
Are you in WA? I’ve got some old gear you might be interested?
Grew up there, in CO now ha. If you want you can shoot me an email anyway, it's in the channel's about page (might have to be on desktop to see it). Maybe we can figure something out.
Pinging 255.255.255.255 is a quick and dirty way to get the IP address of anything on your LAN, unless the device is configured not to respond to pings to that broadcast address. The CLI will usually only show the first address that responded, so IIRC you have to look at the ARP table or have a pcap running on the interface to see the rest of the devices.
yeah that's a good trick. didn't try it with the watchdog but had no luck on that IMM unfortunately.
I don't need it, I don't need it, I don't need it. But maybe after the day today was, this was such a good watch.
Haha. Thanks for watching!
Christ, I'm pretty sure the APC rack monitor I'm actively running in my DC is the same age
I did that same thing on my dell. I didn’t mean to close it but bumped it and snap.
omg I totally forgot about this company- that stupid little dog logo brought back memories 😂
what is a 4124 SIP adapter to FSX interface for integrating 24 analog phones? and can you use one?
14:25 this is always the story with old hardware. I mean there is gazillion memes about that: 20 year old video, 10 year old comment, 5 year old reply. Classic. The best is when you don't even need to tailor the answer to your case - it just matches exactly.
that weather goose turned out to be cooler than I thought-the backdoor password would totally NOT fly in 2024 security always kind of funny to see how "security" was back in the day lol. you might be stuck replacing the riser card for your R720 to fix the intrusion switch issue. unless you can find the wires in that and basically tie it together so it thinks its always closed. Also. Pro Dell poweredge tip, Dell servers like you visiting the lifecycle controller so it can "add to inventory" that's a dell-branded card once you do that it may show up (the 10GB card) in idrac for monitoring...also that can tell the server to re-adjust its fan speed profile for that new card. not required, but a good idea Unless you have CSIOR enabled ( collect system inventory on reboot)
yeah I just turned it off in the bios lol. thanks for the inventory tip!
Dang, really much as I stood for.
I think you kann make the vm vlan aware (i know that you can do it with a lxc container) and than you can put the vm an a vlan and assign a port to the vlan. But im not 100% sure if this idea is going to work.
You dont Need to add an IP to an Bridge. The ip is only needed if you want to Access the Proxmox Webinterface from the Bridge Network. Just let it empty if you just want to pass a nic. Then you just Need to configure the ip in the vm
yeah I figured that out later lol
Why not make a vlan on your ubiquiti network?
That would be the most reasonable way to do this. But I'm always looking for reasons to use this other gear + server capacity I have haha.
Please sell “Weather Goose” t-shirts with that goose graphic on them. 😂
😂
you're slowly accruing equipment of similar vintage and in this case exact manufacturer and model to the rack I managed at my last job. you just need a bunch of iBoot stuff and a Dell Precision rackmount server running Cacti.
Ha nice! Cacti is on my short list of things to mess with 👀
Or a copy of Obsevium or LibreNMS....
11 linksyses?
funny to think that a microcontroller can do exactly that, and probably faster. imagine an esp32 and an sd card and some io. how technology moves! btw, what's inside this goose device? I wanted to see a teardown!
I'll open it up next time it's in a video!
Of it wasnt for a OneNote file I have named HugeMcLarge, I also would not remember any network configurations.....
