remsh problem

[Miguel Velasco]

Hi,

When i do a remsh to another machine, the system sends me an error: rresvport: socket: All ports in use.

Thanks

nstrtel specifies the number of telnet device files that the kernel can support for incoming telnet sessions.

Im confused are you trying to do several remsh at the same time? When are you getting this error? And what command string are you are typing?


Thanks

Is the following line in the /etc/inetd.conf file:
shell stream tcp nowait root /usr/lbin/remshd remshd

Hi,

Just an idea. From you question it follows that there is no free ports on the remote server.
remshd, similar as rlogind, uses only ports from the range 512 - 1023 (in the order 1023, 1022, and so on ).
The warning you mentioned in your question indicates that all these ports are busy.
The simplest way to check ports is to use netstat command on the server.
Also to confirm this reason try to rlogin to the same server.
You can also try to use rexec instead remsh.

Hope this helps.

Rgds.
