hi all

i have a rhel 6 machine, everything i reboot the machine from other computer, i can not remote it back even use ssh or vnc, also can not ping the machine's ip, i have to go to the rhel6 machine to login first, and the other computer could ssh and vnc the rhel 6 machine, anyway to prevent this by going to the rhel6 machine to login before other computer could ssh or vnc ? thx

Spell out your words, please.

And the way you've described your problem makes no sense. Are you saying that you just have to go to the RHEL6 console, log in, and do NOTHING ELSE, and all your network services then start working? If so, I've never heard of such a thing. Normally such problems are related to an incorrect/invalid network configuration (needing someone to bring up the interface manually), services not being started (again, having to start them manually), or a firewall issue.

What do you do after logging in at the console? And bear in mind that RHEL machines shouldn't have to be rebooted..they're servers, and are designed to run for VERY long periods. Also, RHEL is NOT FREE, and if you're using it, you should be paying for it..part of the benefit of that is you could contact RedHat support. Otherwise, consider loading CentOS instead.

Is the network configured using NetworkManager?

If it is, you should either check the "available for all users" box on the connection (this will start the connection at boot time) or reconfigure the network with the usual configuration scripts in /etc/sysconfig/network-scripts/

Can you please elaborate tell configuration of Network Manager for "available for all users"?

Thanks

There's no much to elaborate
See the attachment for a screenshot from Fedora 15 (but RHEL/CentOS/SL config interfaces are quite similar)

Hi,

I was on a machine running CentOS 6.0 and checking "Available for all users" didn't help me. It was the "Connect automatically" button that made the difference in my case.

Cheers..

Oh... ok. I didn't think of that because it's on by default iirc. Anyway, solved

Thanks, this worked for me like a charm
