linxux proftp connection refused

I swear, I go through this same problem every time I set up Linux, but I keep losing track of the solution.

I have a new Linux box, kernel version 2.6.21. It is on an office lan whose others hosts are all Windows boxes. I can 'run -> ftp hostname' from any windows worstation out into the real world, but I can't ftp to this linux box. I get 'connection refused'. On the linux machine I try "ftp localhost", same thing. I have enabled proftpd in inet.conf, put "windowshost: ALL" into my hosts.allow file and done 'kill -HUP 1' to restart inetd. No go. What more do I need to do?

You should have a line in your /etc/inetd.conf something like in the box
ftp     stream  tcp     nowait  root    /usr/sbin/tcpd  proftpd

As root, do an "lsof -i" and verify that inetd really is listening on port 21. "Connection refused" would indicate that it doesn't.

Try this:
~# chmod +x /etc/rc.d/rc.proftpd
~# /etc/rc.d/rc.proftpd start
~# ftp localhost

if it works, it should now start automatically on boot

Hi,
first check firewall settings, allow 21 port if firewall is eanbled
second, check the logs (/var/log/messages) for any information

duncan_roe: when I run "lsof -i" there is nothing for ftp

wod: I am ftp'ing to another linux host fine that does not use rc.proftpd. I assume that one is just using services/inetd.conf. These appear to be configured propery on the 'bad' machine. the proftpd.conf files are identical on both.

When I run proftpd -t (test config file) I get:
 - IPv6 getaddrinfo 'webserver.ohprs.org' error: Name or service not known

When I run 'proftpd -n -d 1' I get the above message and:

webserver.ohprs.org - fatal: Socket operation on non-socket

Any idea what this is? My host name is webserver and the local domain is ohprs.org. These are configured in my /etc/hosts file.

Wassup? I'm needing this real soon!

duncan roe: Yes, I've got exactly that. I'm thinking if I can fix the getaddrinfo error it might be OK. Any idea what the problem is on that?

Possibly proftpd was built for IPv6 but your kernel wan't(?)
It's odd though that you have that line in inetd.con yet you can't see the port listening. I wonder if this is a new inetd that uses a different config file? I would concentrate on resolving that for now.

This is a straight slackware download from about 3 months ago. I did no building, vanilla, out of the box. I didn't even have to add drivers. I'll work on the addressing first and get back to this thread. Thanks

OK - I've added my linux host to the LMhosts file on the Server 2003. So now I can reference the host by name from there. However, this made no difference on proftpd. I've posted my proftpd.conf file below. I'll repeat the error messages here:

When I run proftpd -t (test config file) I get:
 - IPv6 getaddrinfo 'webserver.ohprs.org' error: Name or service not known

When I run 'proftpd -n -d 1' I get the above message and:

webserver.ohprs.org - fatal: Socket operation on non-socket

These messages don't tell me anything useful (to me). Does anyone know what they mean?

duncan_roe, inetd doesn't appear to have a version switch, but ident shows:
     $OpenBSD: inetd.c,v 1.79 2001/01/30 08:30:57 deraadt Exp $
     $Slackware: inetd.c 1.79s 2001/02/06 13:18:00 volkerdi Exp $
these don't look all that new. In fact they are the same as on the older Linix 2.4.29 where proftpd seems to run fine.

Below the proftpd.conf listing is the version/configuration of proftpd on the system that is NOT working: proftpd -V

More information. I copied the proftpd version 1.2.10 from my older Linux system and replaced the 1.3.0a version on the newer Linux. This time proftpd -t worked. If I change the proftpd.conf file to specify standalone and run 'proftpd -n -d 1', that now works and I can ftp files. I can also now use inetd. There must be some funky build setting in the 1.3.0a version. I suppose I could research it, but the heck with that! I'll just run 1.2.10.
