server response is slow
 

I have a many server in in remote site , they are in same network , same segment , the hardware should be the same , but sofware / program in the server is a bit different .

I just found that one of them have problem , the response is relately slow , when I use ssh to connect it , the login prompt take about 10 second to pop up , while other machine have very quick response.

checked that the firewall is enabled , which all server are also enabled firewall , so I don't think it is the reason



ip6tables 0 off 1 off 2 on 3 on 4on 5 on 6 off

iptables 0 off 1 off 2 on 3 on 4 on 5on 6 off


I also checked the server resource utilization is very slow , and the server run normal after login .

it is redhat EL 5.3.


Can please advise what is wrong in my server ?

Thanks.

I Guess it could be DNS issue .How do to connect the server with domainname (or) else via ipaddress.


Try out by enable usedns to no in your sshd_config file and reboot the server .check out whether you can login into server without any delay in login prompt
