[lug] Another local network question

[Greg Horne]

When I first installed Redhat 7.0 on my system a while back ftp and telnet 
did not work, but I could ping my computer.  What install did you use?  
Workstation, Server, Custom?  For some odd reason if you choose a worstation 
install with RH7 ftp and telnet will not directly after install.  To fix it 
I just did a custom install making sure I added everything the server 
install used, plus extras like X.
