We have both ftp and telnet on the blu server, which is RH 5.2 out of the box. 
There are a couple of ftp clients on the distribution, ftp and ncftp.
ncftp is the newer, more interactive version. 
Here is a URL for the Linux Howtos: http://www.linuxhq.com/HOWTO/
Both ftp and telnet are very straight forward. All he should need to do is to consult the man pages. He can always go to the Red Hat site, or one of its mirrors and download the latest RPMs. Without details, it's hard to provide any sound advice. There are some files in /etc which affect access to inbound ftp. 
He will need to have ftp and telnet enabled in /etc/inetd.conf:
 
ftp     stream  tcp     nowait  root    /usr/sbin/tcpd  in.ftpd -l -a
telnet  stream  tcp     nowait  root    /usr/sbin/tcpd  in.telnetd

WRT: Hosts file. There should be at least one entry for localhost. Normally,
the local machine name and ip address also goes into the hosts file. 
Make sure that /etc/resolv.conf is properly configured for name server.
