remsh error

[Rpger Tavener]

Hi

Tyring to remsh from serverA to serverA
and we keep getting this error:
remsh servera -n date
rresvport: bind: Permission denied

If we just do a remsh serverA (without the -n date) we get connected OK.. This happens no matter which user id try.. Any ideas would be appreciated..

Thanks

Hi Roger,

Could list the remsh command,

# ll /usr/bin/remsh

Hi Roger,

check the permissions for remsh, they should be -r-sr-xr-x. If required set the permissions using chmod to 4555.
chmod 4555 /sbin/remsh or /usr/bin/remsh. Check out which remsh is being sourced by trying "type remsh"

Hope this helps.

Hi Roger,

# chmod 4555 /usr/bin/remsh

You are missing the sticky bit.

tried chmod 4555 /us/bin/remsh , still no luck..

Check if
nslookup servera
comes back with a valid IP address.

Then check to see if it can get the host name based on the IP.

What do you have in
/etc/hosts.equiv
?

[Rpger Tavener]

Tried the IP address. Still no luck..
/etc/hosts.equiv does not exist..

Hi,

did you check which remsh you use ?

# which remsh

[John Poff]

Hi,

Are you trying this as a non-root user? If so, what does 'which date' return on ServerA as that user? Just curious, but maybe you have a questionable 'date' command on ServerA?

Also, do you get the same error with other commands on ServerA?

Roger,
Does remsh servera -n ls works?

Because the rresvport errors occurs on the remote host side. If the userids are not same, then hosts.equiv file is needed on remote host side.

Hi,

Check the in the /etc/hosts file entry

is there entry for remote server

r u able to ping by name

also check in /var/adm/inetd.sec file in both system.

Thanx

Try the following:

remsh servera -n "/usr/bin/date"

I reckon you aren't picking up "date" from the right place.....

Thanks to all who responded..
The problem was we needed permissions on /usr/lbin/remshd as follows:

-r-xr--r-- 1 bin bin 36864 Apr 9 1999 remshd

We had -r-sr--r--
