Cannot FTP

David Connolly — Wed, 20 Nov 2002 13:45:32 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 to the machine from the machine itself, I get
"421 Service not available, remote server has closed connection"

Any help would be appreciated - This is out web server, and I cannot copy files to it!

Have you checked /etc/services? You should have:

ftp-data......20/tcp...... # File Transfer Protocol (Data)
ftp...........21/tcp...... # File Transfer Protocol (Control)
tftp..........69/udp...... # Trivial File Transfer Protocol
sftp..........115/tcp...... # Simple File Transfer Protocol
bftp..........152/tcp...... # Background File Transfer Protocol
ftp-ftam.....8868/tcp...... # FTP->FTAM Gateway

Yes, thanks. I have all those services.

And make sure the /etc/inetd.conf file contains an entry for ftp.

Has it worked before and just stopped working?

Maybe ftpd has died, maybe it is a DNS issue, maybe the IP or name of the machine was changed.

1.What port have you configured for ftp.
Please make sure that the port is not used by any other process

2.Are you running any TCP Wrappers?

3.Do you have /etc/shells file which restricts the user from login.

4.Does other services like telnet work fine?
check for any duplicated ip.

hi,

- 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 cas, you should create a /etc/shells file, then list all default shells (see man getusershell) and finally add yours.

Regards.

try:

netstat -a | grep LISTEN

then look for port .21 or .ftp.
If you cannot find it - inet.d is not waiting for ftp requests.

Good luck

netstat -a |grep LISTEN shows
*.ftp *.* LISTEN

ignore that - it's since the machine started that P_client is there. My issue began on 14th of this month

Re: Cannot FTP

David Connolly — Wed, 20 Nov 2002 14:37:15 GMT

what's a p_client? I have a bunch of them holding IP sessions in a close_wait state (according to LSOF)around the time of the error.

The FTP listener is there. I can see it using both netstat -an and lsof -i. When I try to connect locally, I get the following

$ ftp lcalhost
Connected to localhost. 421 Service not available, remote server has closed connection
ftp>

Any thoughts?

Have you checked the post from B.H.E.Salden ?
-----------------------------------------------
And make sure the /etc/inetd.conf file contains an entry for ftp.

---

There must be an entry like this:

ftp stream tcp nowait root /usr/lbin/ftpd ftpd -l

If there isn't an entry, create it and then stop and start inetd.

Re: Cannot FTP

David Connolly — Thu, 21 Nov 2002 09:24:02 GMT

Sorry,

Yes - it's there, and I've restarted inetd to no avail.

ftp stream tcp nowait root /usr/lbin/ftpd ftpd -ld -t 300

I discovered problem was continued and solved in as new thread.

Re: Cannot FTP

David Connolly — Thu, 21 Nov 2002 11:02:52 GMT

Adam,

Yes, my apologies - the issue was inetd.sec in /var/adm contained a restriction that prevented FTP from any address other than my router. The router is the issue.
