Hi,

I want to know how to open the telnet and ftp ports for remote access.
Do I need to setup the telnet server? if so, how?
Also, how can I check which port is open and which one is closed?

I am running redhat 7.0.

Thanks

Its done through /etc/inetd.conf, some distributions use xinetd and I suppose it would be /etc/xinetd/xinetd.conf or /etc/xinetd.conf(not sure), you just have to do is remove the # from the line telnet is on and restart inetd or xinetd by doing inetd restart or xinetd restart.

Hi,

I can find xinetd.conf. But, there is no # for remove. There is a xinetd.d dir in which there is a telnet file.

Is it mean that the telnet was on?

Thanks

Hmm thats right. I forgot xinetd is different from inetd. I don't use redhat so i end up making such mistakes. Sorry.

I think redhat has a "Setup" utility to enable telnet. man xinetd.conf and man xinetd should help you a lot.

Gogo,

To add ftp and telnet services you need to install the telnet and ftp
server daemons. These are in the wu-ftpd and telnet-server RPMs.
Check to see if you have them installed already with
rpm -q wu-ftpd
rpm -q telnet-server

If they aren't installed get the RPM for RH7.0 and install them (as root) with
rpm -Uvh wu-ftpd*.rpm telnet-server*.rpm

Then go into /etc/xinetd.d and look for files named telnet and wu-ftpd.
Look for a line that has "disable = yes" and change yes to no. It should end up
looking similar to this:
service telnet
{
disable = no
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
}

Save and then restart xinetd with:
/etc/init.d/xinetd restart

You should be all set.

To test if a port is open you can always just telnet to it but I suggest
familiarizing yourself with nmap. nmap will port scan your box
and report all open ports on it. nmapfe is a graphical front-end for
nmap. I use Mandrake and I'm not sure if nmap or nmapfe are installed
for RedHat by default but you should be able to find RPMs for them
both.
