Unable to connect with telnet, ssh, ftp, etc...
I Have a redhat linux machine that locked up.
Unable to connect to machine with telnet, ssh or ftp. Services going out of the machine webserver, mysql, mail are working. 2 questions: 1) how to I gain access back to the machine? 2) what log or files do I look at to troubleshoot and fix the machine? This has happened a few times. A reboot regains access for a bit. Since the machine is in a data center rebooting is not the best option for regaining access. Thanks, ~D |
Providing you have physical access to the server you should be able to open a terminal- Do you have physical access and can you open a terminal?
Make sure and check 'hosts.allow' that it contains: Code:
ALL: ALL: allow Code:
ALL: ALL: deny Sometimes SSH access can be restored by 'stopping' | 'starting' your firewall too. You may just have to go with a reboot though??? Hope this helps in some way? Regards |
