Proxmox Network Issues....

[MrBubblez98]

I'm trying to install Proxmox and connect the to the web GUI, but I'm having some issues... Motherboard is Gigabyte 990FXA-UD3 Rev. 4.0. Using onboard NIC, I configured it to be 192.168.1.253, /24, and the DG and DNS 192.168.1.1, which is my router. I did notice that the default IP was 192.168.100.x, which is a totally different subnet. After installation, I logged in and tried to connect to the web GUI but wasn't able to. Tried to ping gateway and wasn't able to. Tried to ping the PC and nothing. I played around with it for a bit, and still nothing. Bought a $25 PCI (not express) NIC at a local store and immediately noticed a difference, the default IP was on the .1.x subnet, which is already a big improvement. Got it installed, logged in, and I was finally able to ping the default gateway. HOWEVER -- it was not consistent. It would have a few successful pings, then drops for a few, and back and forth. Same going from my PC to the VM PC, it was intermittent. So far I have tried with the latest version of Proxmox, 4.4, as well as 4.3.

 

I wasn't sure if I should post this in the Network subforum or the virtualization subforum, but since it's a networking issue I figured it'd be best here.

 

Any help is greatly appreciated!

 

Thanks,

I am logged in as root, that's the default user.

 

I asked on the proxmox forums, and they told me to type "lspci -k | sed -n '/Ethernet/,/Kernel/p'". I did this, here's the result:

 

Ethernet controller: Realltek Semiconductor Co., Ltd. RTL8169 PCI Gigabit Ethernet Controller (rev 10)

Subsystem: Pretty much same as above
Kernel driver in use: r8169

Looks like pinging your DG works... DNS lookup is working.

 

Is the PC you are trying to connect from on the same subnet as the proxmox server?

Yeah, they're all on 192.168.1.x

whats the error on your PC when you try to get to the web GUI

 

[MrBubblez98]

It's just the default Chrome error message, "This site can't be reached. \n<IP> took too long to respond..."

[unijab]

what url are you using?

https://192.168.1.253:8006/

 

I did it before and it told me that the website is unsafe, and prompted me to continue to the site or go back to safety, so the URL is correct. But for some reason it just goes down temporarily and it stops loading..

[unijab]

If you got that warning.. seems like it is working

[MrBubblez98]

But it still cuts out randomly, effectively making it useless for me. It disconnects before I have a chance to connect to the UI.

run a trace route from your pc to the proxmox

[MrBubblez98]

C:\Users\Michael>tracert 192.168.1.253

Tracing route to 192.168.1.253 over a maximum of 30 hops

[unijab]

That is odd output... for devices on the same subnet.. I'd expect 1 hop and done.

 

 

not 7 hops...
