i have installed linux 7.2 OS , the problem is i cant ftp into this machine from some other machine on the network , outgoing ftp is working but incoming ftp and telnet isnt working , the telnetd and wu-ftpd daemons are running . Please suggest the needful as to what are the files to modify to get this service up and running.

Look in both /etc/xinetd.d/telnetd and /etc/xinetd.d/wu-ftpd to make sure that the line that says disable = no However, you may want to consider using sshd and proftpd or vsftpd for better security reasons... taurus

i have checked the /etc/xinetd.d/telnetd and /etc/xinetd.d/wu-ftpd and there disable is equal to no.Is ipchains the problem in this case like some rule in it is preventing incoming requests.

Could be. Also, look in /etc/services and make sure that you have those ports open for telnet and ftp. May want to take a look at the script files in /etc/rc.d/init.d as well... taurus

My guess is your firewall. Disable it to check , if you like. Then use "lokkit" or "redhat-config-securitylevel" and set up allowing ftp to come in. You say you're using linux 7.2, which I assume is Redhat 7.2, in which case I believe the aforementioned utilities should be available to you (I'm using Redhat 8). Good luck.
