Strange network problem

acidflux · 2006-10-16 16:29:33

Hi, I'm having a strange problem with my network...

During the boot, the network daemon has been successfully started. I can browse the net using firefox. But the strange thing is I can't do anything else besides browsing. I can't connect to the repositories and download packages using pacman, I can't log in with gaim, I can't log in skype, etc.

When I try to log in using gaim, it gives me an error saying I need SSL packages installed. Actually I had openssl installed. Well, then I download the openssl package using firefox and reinstall it. But after that I can't start gaim anymore. It just crashed

Anybody can help me?

Thanks in advance!

How do you connect to the net? Is it a direct connection or are you behind a firewall?
run ifconfig, route, and as root (mii-tool) and post them here for us to take a look.
Also in your /etc/resolv.conf you have the correct entries pointing to your DNS server correct?

I am behind proxy...

This is the output of ifconfig

And yes, the entries in /etc/resolv.conf are right. I think I wouldn't have been able to browse properly if the contents are wrong....

Oh yeah, I think I also need to note that previously I didn't have this kind of problems. The network went mad just recently...dunno what causes this.

Thanks for your help!

sounds like your network changed something. perhaps they installed a firewall or changed their proxy rules.

acidflux · 2006-10-16 20:47:17

I'm really not sure what I have done but now it worked like it used to be :?

I don't think there were some changes in my network for that slight amount of time, because I managed to login skype using other os in my other partition.

I will inform you all again the next time I reproduce the error

Thanks!

Actually ... I thing that something DID happen because your IP address is reported as 172.20.124.26 but your gateway and broadcast adress are pointing to a different sub-net 172.20.127.255

Also your gateway is the same as your broadcast 172.20.127.254 while it should be 172.20.127.1 for that specific net address.

Mask: 255.255.252.0

He's part of a private class B that probably looks like this:

172.20.124.1 - 172.20.127.254

Also, .1 as a gateway is only a convention, not a requirement.

ralvez · 2006-10-16 22:03:49

Agreed, but 254 is the broadcast and the gateway shares the same address ... that's odd.

cactus · 2006-10-16 22:36:43

broadcast is .255, not .254

ralvez · 2006-10-16 22:51:12

Hum... I need new glasses I misread his posting. It actually does state broadcast as 255 I do not know why I thought it was 254 which would be a problem particularly if it was the same as the gateway...

Nevermind ... I'm going to sleep.
