 Posted: Sun Sep 28, 2003 10:54 pm Post subject: Network lockup |
 |
|
I've been getting network lockups periodically.
Basically, often when doing such things as connecting to IRC or serving a file, my network will completely stop responding (sometimes, my streaming audio continues; this baffles me). I cannot ping even my nameserver (not to mention google), and if I rerun dhcpcd it becomes unkillable and crashes my system. The only way to fix this is to unplug, then replug my router (a Speedstream 2604; crappy, but worked fine before) and then rerun dhcpcd several times.
I've just recently moved, and switched providers as well (from Verizon DSL to Yahoo/SBC DSL). SBC uses PPPoE, Verizon doesn't.
I've also switched to 2.6, so that may be the problem (the kernel bugzilla reports nothing, though).
This has happened with all of my various 2.6 kernels.
My network card is a 3c905, and it appears to work fine normally.
Emerge info output:

This can happen up to several times a day, and sometimes, when I leave the house in the morning and come back during the day, I see
that gaim has disconnected and unsuccessfully tried to reconnect
many times, but now is able to.
Any ideas?[/code] |

| When the 'lockup' occurs, are you able to contact or ping any NUMERIC ip addresses? I.e. avoid doing a DNS lookup. |

I tried pinging both my nameservers by IP and that didn't work--gives me a Host Unreachable.
Streaming audio works....why? |

I'm having the exact same problem (streaming audio works, and restarting my modem and running dhcpcd -n fix it).
I'm using kernel 2.4 , so I guess it's not a kernel issue, and also I'm using a different modem and network card...
I feel kinda lost, I'm kinda new to linux, but fixed almost everything except for this problem... and it's pretty anonying because it happens often.
Any help would be great. |

| When it is working, do a /sbin/ifconfig and /sbin/route -n. Then when it stops working, do the same thing. Any differences? |

| I didn't see any differences between working and non-working... Perhaps you could explain you network setup a little more? It looks like you have some device doing NAT. What device is that? |

It hasn't happened since I did this:
Enable Packet Socket: mmaped io under Networking Options in the kernel config. Perhaps it is something they fixed in -test6-mm4, though, but that seems unlikely. In any case, haven't had a problem since (though may still later) |
