networking problems in Slackware 10.2

WRSpithead · 09-27-2005, 07:20 PM

I have been having a problem where certain things won't connect between either the internet or another device. Origonally, I was having a hard time getting gaim to connect using any of the instant messenger protocols. I mean none. It couldn't get any data through.

I found a wierd workaround for this where i would use "tcpdump" and sniff any packets going to AOL's address. As long as it was sniffing that address, gaim could log in. I can only guess that tcpdump was allowing a way for data to get through from the software level to the hardware level. Maybe it has something to do with sockets. I don't know.

Now, I want to route my xbox through slackware and I can't do it. Although I can do it in SuSE linux, the xbox fails to even detect the gateway (slackware), which of course means it is unable to even ping my computer.

I guess the two incedents are related. Gaim probably was not able to open up a socket and transmit the data to the internet, but as long as tcpdump was there to re-send the data it was able to go through. The xbox is probably encountering the same problem. I don't know where or why, though. If I did I might be able to fix it. I need some help from all teh uber l33ts out there! Please respond if you have any idea of what might be going on.

Do the settings in /etc/rc.d/rc.inet1.conf look correct ?

Also, have you the right nameservers in /etc/resolv.conf ?

Oh, no, the computer itself can connect fine to the internet. I can bring up anything with a web browser just fine so it's not the nameserver and it's not anything IP related. Remember, I tried it on slackware and on suse and slackware was the only one it didn't work on. Just the fact that gaim wouldn't connect to the server without it being re-routed via a sniffer tells me that it is something low-level or kernel related, not something stupid like the wrong ip address or nameserver. And, yeah, I have looked at /etc/rc.d/rc.inet1 quite a bit and nothing seems wrong.

Just so you know, here is the layout of my xbox and my computer. Remember that the xbox cannot even DETECT my computer when it is running on slackware.

Code:

XBOX ( IP = 192.168.1.2        )
     ( MASK = 255.255.255.0    )
     ( GATEWAY = 192.168.1.1   )

                 |
                 |  (crossover cable)
                \ /
                 `
ETH0 ( IP = 192.168.1.1         )
     ( MASK = 255.255.255.0     )
                  .
                 / \
                  | (routing tables)
                 \ /
                  `
WLAN0 ( IP = 192.168.0.3     )
      ( MASK = 255.255.255.0 )

                |
                 )
                (        (wireless)
                 )
                |

INTERNET ( IP = 192.168.0.1     )
         ( MASK = 255.255.255.0 )

Here is the routing table info on slackware:

Code:

Address      |      Mask          |      Gateway          |        Device
--------------------------------------------------------------------------------
0.0.0.0       0.0.0.0              192.168.0.1             wlan0
192.168.1.0   255.255.255.0        192.168.1.1             eth0
192.168.1.0   255.255.255.0        0.0.0.0                 eth0
192.168.0.0   255.255.255.0        192.168.0.3             wlan0
192.168.0.0   255.255.255.0        0.0.0.0                 wlan0
