FTP Problems (continued)

David Connolly — Thu, 21 Nov 2002 09:17:19 GMT

Hi,

When I try to FTP to my server, it immediately responds with "Connection Refused" - no pause, no delay, no prompt for username, nothing.

I tried kill -s SIGHUP pid where pid what the process of the inetd daemon.

I also checked /etc/ftpusers, and tried removing all entries. It made no difference,

I know it's not a router or firewall issue, because I'm FTPing from a machine on the local subnet.

When I ftp localhost from the machine itself, I get
"421 Service not available, remote server has closed connection"

There is an entry in /etc/services for FTP and the listener is there when I look using lsof -i, and netstat -an

Any help would be appreciated.

hey !!

have you checked the following

1. /etc/ftpd/ftpusers
2. /etc/inetd.conf (ftpd -l)
3. /etc/shells
4. /etc/ftpd/ftpaccess
5. /etc/netgroups
6. /etc/nsswitch.conf (for th proper order of services file )

and also verify the port number on the host from where
you are trying to connect.

Hi,

Some people asked you information in your previous post, but I can't see any answer to these questions :

- check in sam, Networking and Communications, Network services that FTP is really enabled

- check that the user you are using to transfer has a 'standard' login shell. If it's not the case, you should create a /etc/shells file, then list all default shells (see man getusershell) and finally add yours.

- do you use a /var/adm/inetd.sec file ? If yes, you could try to rename it just during an ftp session.

Regards.

Niraj,

Thanks. Yes I have checked these files, and they are identical to a system where FTP works.

Nothing has been altered on the system since I last FTP'd to it. It stopped working last thursday at 21:00 when I wasn't even here! No one else has access to the machine. I know when it stopped, because the monitoring agent on it (Firehunter) uses FTP to transfer it's stats to the central monitoring station, and I haven't got stats since then.

I immediately thought "Firewall", and the firewall's disk was full, which might have prevented the machine FTPing to another, but surely that could not have affected
ftp localhost?

Thanks - inetd.sec in /var/adm contained an entry limiting the ftp to the router. I changed to localhost, and can now FTP from localhost. There obviously was some change on the router.

Will investigate.
