Hello,
I'm new to linux (the person who installed the system is not available right now), and i'm having trouble getting access to ftp outside my network to work.
On one specific (and very important ftp server), I get the Cannot build data connection: Connection Refused error. I've tryied passive mode, but it doesn't work (time out). The active mode works only when accessing the ftp through my linux server, which is directly connected to the internet. No computer that is behind the linux server can access that ftp.
I've seen some posts advising users to active the ip_masq_ftp module, but as far as i can see it is already running (it is being run in the rc.firewall, and is displayed when i list all the modules running).
How do I reinstall it? When i run the depmod -a, I get a lot of errors messages like this:
depmod: *** Unresolved symbols in /lib/modules/2.2.14-5.0/net/3c503.o
depmod: *** Unresolved symbols in /lib/modules/2.2.14-5.0/net/3c503.o

And is there any other way to get the ftp to work?

Thank you very much,

Wow, that's all I can say.

Whomever set your kernel up(it appears) has every network card driver possible trying to load. The absolute first thing you need to do is figure out your driver and stop trying to load the rest. The reason your seeing all those errors is obviously because those cards are not installed.

The second suggesting would be to manually try to load the ip_masq_ftp module, this is done by:

# modprobe ip_masq_ftp

optionally you can specify which ports to do this on by

# modprobe ip_masq_ftp ports=21,200,...

note, you MUST be root to enable this module.
It appears you know how to do this, but to list your modules you run:
# lsmod

Hope this helps,
J
