Network problems on doing FTP

[heyyunus]

Hi,

I have got RHEL 4 AS installation on a P4 pc. The problem is whenever i do a FTP to it say about 20-30 MB file, upon completion of file transfer the network goes down on that m/c. And then i cant ping/connect to that m/c untill i reboot it.

My network is Cisco catalyst 1 GB n/w and its definitely not a problem with network, I guess something to do with the m/c itself. As a matter of fact, i havent upgraded the NIC drivers bcoz i couldnt find it.

Please help

Instead of rebooting try issuing:
[green]/etc/init.d/network restart[/green]
or
[green]/etc/init.d/networking restart[/green]

You shouldn't use regular FTP if it can be helped because of security reasons. Opt for SFTP instead.

Alright, time to get to the bottom of the problem though...
1. What shows up in the logs?
2. Do any other services cause the issue or is it limited to FTP?
3. Anything "odd" in the /etc/sysconfig/net* folder(s)?
4. Any ipfilters set up on the machine?

Even if i give "network restart" it doesnt solve the problem. So I have to reboot.

GSSFTP is installed, which came as default with RHEL4. Currently i see the problem with FTP only.
Nothing odd in /etc/sysconfig/net* folder and also no iptables/ipchains or TCP wrappers are configured.

I have done "service iptables stop" permanently at all init levels.

Anyting else that i can check off.

One more thing is that when I boot , i get this error "IRQ error, try booting with acpi=off, Disabling" I dont know whats this.

IRQ is a way for hardware to get the attention of the cpu. The lower the number, the higher the priority the cpu gives them when they raise their hand. The Advanced Configuration and Power Interface (acpi) is having a little fit over it and doesn't wanna play no more. There seems to be a conflict with some of your hardware or memory. Ports are nothing more than memory segments. It is my guess that port 20 or 21 just happens to be where the conflict is. I'm not sure what the fix for this would be but you may want to start where the error message suggests and disable acpi on boot up. The startup script is /etc/rc.d/init.d/acpi. If you still get the IRQ error, then check all the cards in your motherboard and run diagnostics on all your memory.
