connection reset after 4096 bytes when using FTP to access remote server


Hi,

I keep getting this weird problem, that seems to come and go.

At the moment I am unable to transfer more than 4k of a file to my remote server (Plesk box, running FC2) using any FTP program (on windows). I thought this may be a specific Plesk problem, and have posted on the Plesk forum, however, I have had little joy in resolving the issue, and think it may be a more general network problem.

I have been getting the following errors consistently in my /var/log/messages file -

- init: Id "T1" respawning too fast: disabled for 5 minutes
- dhclient: sit0: unknown hardware address type 776 (* this is after I restart networking - but I can still access the box)

I have checked the client side of things and they are all ok. Can access other remote servers without problem. Firewall rules all seem ok. Using lynx remotely works also, and I can also remotely retrieve files to the server (i.e. download stuff remotely). I have not been able to check using a different machine (win or llinux), but don't see that it would make any difference anyway.

This error is doing my head-in to say the least, and is making my server unusable.

If anyone has any ideas on a fix and a way to prevent it happening in the future then I would be extremely grateful!

output from ifconfig is as follows (* out my IP)

Get this after restarting network (service network restart) -

sysctl: net.ipv4.ip_forward = 0
sysctl: net.ipv4.conf.default.rp_filter = 1
sysctl: kernel.sysrq = 1
sysctl: kernel.core_uses_pid = 1
network: Setting network parameters: succeeded
kernel: Disabled Privacy Extensions on device c0375440(lo)
network: Bringing up loopback interface: succeeded

seems ok... what are the Privacy Extensions that are being disabled?
