FTP Not working

[mphayesuk]

I can ftp to the server fine in my internal network but external it wont work. Plus I cant find the log for the ftp server. And when my server starts I get a warning about there is another ftp server running. Here are the two proftpd config files. # This is a basic ProFTPD configuration file (rename it to # 'proftpd.conf' for actual use. It establishes a single server # and a single anonymous login. It assumes that you have a user/group # "nobody" and "ftp" for normal operation and anon. ServerName "ProFTPD Server" ServerIdent on "FTP Server Ready" ServerType standalone DefaultServer on # Port 21 is the standard FTP port. Port 21 # Umask 022 is a good standard umask to prevent new dirs and files # from being group and world writable. Umask 022 # To prevent DoS attacks, set the maximum number of child processes # to 30. If you need to allow more than 30 concurrent connections # at once, simply increase this value. Note that this ONLY works # in standalone mode, in inetd mode you should use an inetd server # that allows you to limit maximum number of processes per service # (such as xinetd).

You can ignore the warning.

If you cant FTP from otside, it is in most caeses a firewall issue. have you tried both, active and passive FTP?

[mphayesuk]

My router firewall is not on, and the default one for suse is not on either. But I will check all of them anyway, it does sound like the router because it will work inside my network

Thanks

I am 98% certain that my router is not the problem any ideas where to start on the server, ssh wont work either outside my network but pop mail and web pages are working ok (except for perl scripts).... So where do I start.

Thanks

Ask your ISP if they block certain ports like 21 and 22.

[mphayesuk]

Checked with the ISP and they do not block any ports.

Thanks

Did you forward ports 21 and 22 from your router to your ISPConfig box? Maybe also port 20 for FTP.
Did you try both active and passive mode in your FTP client?

[mphayesuk]

I have turned off the firewall on the router so that my server is public. At the moment port 80 and 81 and 110 and 25 work fine... so I am guessing that something on the server is stopping the ftp and ssh from working seeing as though everything else works fine through the router.

Thanks

Ok so I can ftp from my internal network using the public addresses.

BUT I cant ftp from the outside and also I cant ssh from internal or external.

The firewall on my router is not on, ISPC's firewall is not on, but when it is nothing works and as far as I can tell there are no other firewalls turned on including the default suse one.

Web (port 80) https (port 81) and mail (port 25 and 110) are working fine so can anyone shed some light as to why ftp and ssh will not work.

When I try and ftp I get a connected to "address" and then after a minute or so I get "connection closed by remote host"

When I am trying ssh and use telnet from windows (or putty) after typing telnet "address" 22 I the screen gets cleared and I am left with "SSH-1.99-OpenSSH_4.1 with a blinking cursor underneath and then after a while I get a message saying "Connection to host lost"

My ISP does not block any ports.

Can anyone help with this one.

Thanks

Quick note on ssh, when looking at the config files /etc/ssh/ssh_config and sshd_config why are most of the option commented out, I would expect to see more options enabled here is the file.

ssh:
# $OpenBSD: ssh_config,v 1.20 2005/01/28 09:45:53 dtucker Exp $

# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.

# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.

# Site-wide defaults for some commonly used options. For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

# ForwardAgent no
# ForwardX11 no

# If you do not trust your remote host (or its administrator), you
# should not forward X11 connections to your local X11-display for
# security reasons: Someone stealing the authentification data on the
# remote side (the "spoofed" X-server by the remote sshd) can read your
# keystrokes as you type, just like any other X11 client could do.
# Set this to "no" here for global effect or in your own ~/.ssh/config
# file if you want to have the remote X11 authentification data to
# expire after two minutes after remote login.
