CENTOS 3.9 Server can see localhost and DNS Name but not IP Address
I have just installed CENTOS 3.9 apparently succesfully.
I appear to have vsftpd and telnet "on" after doing some config stuff. I can ping out from the server to other servers so am definately on the network. I can ping localhost and full DNS name from the server itself but NOT the IP address of the server itself. I can not ping, telnet or ftp to the server from elsewhere using either DNS name or IP address. Any ideas please? |
have you configure any firewall?
This problem is quite odd, since you can ping yourself with your domain name. This server is just setup or used for long time? |
Brand New Installation - No Firewall
As the title suggests... I have only just completed the installation from a CD created off the WEB a few days ago. I purposely did NOT activate a firewall during the installation - there was an option to do so.
I agree it is a bit strange, and hence my question on the forum!! I will probably try another install from scratch, but this is already my second install with the same issue occuring. I just wondered whether I needed to do anything in any of the networking config files that I was unaware of. |
Partly Solved!!
OK - I found some stuff about network configuration and started to look at ifconfig and the /etc/sysconfig/network-scripts/ifcfg-eth0 file.
What was wierd was that ifconfig reported the IP address incorrectly, but the ifcfg-eth0 file had the correct value. I used ifconfig -a x.x.x.x to try and set the correct IP address and BINGO!! I can now ping the server both with DNS name and IP address. I had to add a user in /etc/passwd in order to ftp succesfully ( root would not work ). telnet connects to the login screen OK but I can't login as root or as the user I added. I'll keep digging on this one unless anybody has the answer before me!! |
Solved
I decided to use sshd instead of telnet - every body says one should do this anway - and connecting via a sshd client worked first time so I can now remotely connect and ftp.
I love it when a plan comes together!! |
