i always have bad experience with my proftp server. i have it running
but i can't transfr any data. Everytime it always stuck at "Entering
passive mode" for a long time and then timeout. But if I disable the
firewall, it works well. So which port of firewall should i open? I do
some googling and find out port 30000-30050 or 60000-65535, but it
didn't work.
Hello Hans,
It's not your proftp's fault.
In passive mode, the ftp client will connect to the ftp server on tcp 21, then
for data transfer it will open random high ports. In order to do this your
kernel must have ip_conntrack_ftp module loaded, so that it can 'track' the
connection for ftp.
I believe you can set it in your firewall to load the needed module.
HTH,
As for loading ip_conntrack_ftp, that is done in the SuSEfirewall2
script, so the OP must be using some other firewall.
