I'm trying to setup a simple ftp server on Red Hat 7.2 and I can't get beyond "connection" refused when trying to connect externally. I've read every FAQ and online guide I can and I can't figure out why. The big clue I think is that netstat -a says that ftp is not being listened on. /etc/services looks ok to me (ftp is on port 21 for both UDP and TCP), I added the ftp service in /etc/xinet.d/ftp and restarted xinetd, so I'm not sure what could be inhibiting ftpd. Here's my config from /etc/xinet.d/ftp: service ftp { disable = no socket_type = stream wait = no nice = 10 user = root server = /usr/sbin/in.ftpd server_args = -l instances = 4 log_on_sucess += DURATION HOST USERID } I modified /etc/hosts.allow and /etc/hosts.deny too. I wasn't sure about hosts.allow so I copied the working nfs stuff to a new line and changed it: in.ftpd: 10.0.0.0/255.255.255.224 which is just like the entries for mountd, statd, etc. Not sure what else to say. Here's the long story summarized: 1. Dowloaded wu-ftp and built it with ./configure and make 2. Created /usr/ftp and the little jail for it to run in. 3. Check the firewall to make sure it didn't reject ftp. 4. Made changed to /etc/xinetd.d/ftp above and hosts files. 5. Restarted xinetd There maybe a few other things I did, this is what I recall for now. I did a tcpdump trace of the connect attempt, the packets are reaching the server and it replies, but the replies are all R (resets). I think this is related to the fact that xinetd doesn't think it has something to run on port 21 (ftp port). Help? What could I be missing? --------------010807010701030504050807 Content-Type: text/html; charset=us-ascii Content-Transfer-Encoding: 7bit <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"> <title></title> </head> <body text="#000000" bgcolor="#ffffff"> <div class="moz-text-flowed" style="font-family: -moz-fixed; font-size: 13px;" lang="x-western">Hi all, I have a tough problem that hopefully has a not so tough solution.

Problem is with newly added RH 9.0 machines that they are showing the other machines in xdmcp manu but not themselves. so the xdmcp menu we get here on all machines is still with old list. HOw do i make sure that the newly added machines show up in the xdmcp menu? mail me cc of the reply rgds upendra __________________________________ Do you Yahoo!? Protect your identity with Yahoo!

Since 'netstat -a' tells you that xinetd doesn't listen to port 21, you could be able to gather some more information from the logs: after a 'service xinetd restart', what do you find in /var/log/messages? If xinetd can't start wu-ftpd, you should find a trace of the reason there.
