I just installed RH7.2 but I can't seem to telnet or ftp from outside to my machine. Is there something I have to edit? I did not have a firewall in the server,
First, I strongly recommend that you not run telnet on your machine. It is not secure, and sshd is readily available for Linux.
Is the IP address on your machine a private address or a routeable address? If it's private does some firewall or router external to your machine know how to forward to your machine?
Do you have a default gateway configured on your machine?
Are your daemons running? ______________________________________________________________________
TANSTAAFL!
redhat install a firewall by default (iptables) it do not let incomming connection to your pc, so you must disable it:
#iptables -F
#iptables -t nat -F
to not start iptables rules at startup do this :
#chkconfig --level 2345 iptables off
NB: you can see the the actual config by this
#chkconfig --list iptables
by the way, then you probably want to launch the telnet daemon from xinetd. Open the /etc/xinetd.d/telnet file in a text editor (vi) and change the "disable = yes" line to "disable = no". Then restart the xinetd service with the "service xinetd restart" command.
