[newbie] What am I missing?

[Tech R]

I'm getting a little frustrated here. I don't remember going through so much trouble with RedHat as I am now with LM 7.2.  To be specific, I can't connect to LOCALHOST, and Apache.   Tried to connect to WEBMIN by entering  http://localhost:10000 and all I get is unable to connect to localhost error message.   IPCHAINS default policy right now is ACCEPT.   HOST.DENY is not denying anybody, I commented out the entry added by LM.   My HOSTS file has 127.0.0.1    localhost.localdomain    localhost and                            xx.xxx.xx.xx    mymachine.mydomain.com    mymachine     I can ping localhost and mymachine.mydomain.com from a terminal and from a DOZE machine.     So, what am I missing???   Oh, and yeah, I can't recieved mail too.   Tech R
