Connection Porblem

If anyon eread this I need a answer quick. I can ping a machince on my network but I can't connect to it. I keep getting a protocol error. I check everything hosts file .deny .allow.
Can you please help me

well what do you mean connect to it, are you trying to connect to a webserver, or telnet, or ftp, or finger? the computer you are trying to 'connect' to might not have any services open, or even running, what os is the computer running, yours and the server.
if you are trying to ftp or telnet for example,. and you have the ftp and telnet services running, you may have to uncomment the corrosponding telnet and ftp service lines in your inetd.conf file, usually located in /etc also do a netstat -l i think to see if you have any servers listening for connections, that would be your first step, if what you want is running then go check out inetd.conf and see what you have to edit. good luck
