I have a linux server running webmin that I cannot connect to with FTP/SFTP.
Usually I can connect to any server, eventually. But not this one.
I can login and create any kind of user, do anything. But can't access SSH through putty. Putty doesn't even connect to the site. tried VSFTPD, PROFTPD. Tried different ports. Same thing. Reponse times out. FTP times out. SFTP times out.
I disabled webmin's firewall and created all kinds of users with different abilities, no passwords, passwords, different groups, /bin/bash /bin/sh. No luck.
Error logs don't show any FTP activity or provide details of the errors.
I've been at this for about 11 hours today, and I'm about out of ideas. Thinking of using something other than webmin.
The site is a remote ip address 18.104.22.168 with no domain name.
The table output is:
Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere ACCEPT icmp -- anywhere anywhere icmp echo-request ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT tcp -- anywhere anywhere tcp dpt:http ACCEPT tcp -- anywhere anywhere tcp dpt:https ACCEPT tcp -- anywhere anywhere tcp dpt:12320 ACCEPT tcp -- anywhere anywhere tcp dpt:12321 ACCEPT tcp -- anywhere anywhere tcp dpt:12322
So it looks like SSH is accepted along with normal protocols. Yes I know FTP is 21 and SSH is 22. There is no limitation on FTP access from this location. I can access any other site. The linux distribution is Debian Linux 7. The firewall I completely disabled. Deleted every rule.
