remshd[12744]: rresvport: Address already in use

Hi Team,

I  am not able to do rlogin from server A to Server B. rlogin is not giving any error also. But i got the below error messages from the syslog of server B

 

remshd[12744]: rresvport: Address already in use

 

Then i checked for the port which rlogin is using  from /etc/services file

 

shell        514/tcp  cmd            # remote command, no passwd used

 

Using lsof i checked  whether any process is listening  this port

 

     [3]> lsof -i tcp:514
COMMAND  PID USER   FD   TYPE     DEVICE SIZE/OFF NODE NAME
inetd   1466 root    8u  IPv4 0x89092c40      0t0  TCP *:shell (LISTEN)

 

But no process is  using that port.

 

Could you please  help me for sorting this..

 

Regards

Hi

 

 

The port for remote login is 513:

 

login        513/tcp                 # remote login

 

 

 netstat -an | grep -i 513
tcp        0      2  172.28.5.47.513        172.28.5.48.1023        ESTABLISHED
tcp        0      0  *.513                  *.*                     LISTEN
