rsh problem

Prasad Joshi — Fri, 28 Apr 2006 04:09:40 GMT

I am trying to connect to the HP-UX system from my desktop which is Linux through rsh.

I am getting this error.

D-T11673A:~ # rsh slpam15
rlogind: Host address mismatch..

Can any one help?

Thanks & regards,
Prasad

Prasad,
have tried using the ip address of slpam15.
Also check that the correct ports are open.

Hi Peter,

I have tried with IP Adress but, getting the same error.

If I try the same from another HP-UX machine there is no problem.

Thanks

Seems You have more than one LAN card on the HP-UX machine and hosts file returns the incorrect IP address back to client. This caused the error messages.

Take a look at PHNE_23003 patch (r-commands cumulative patch).

bash-2.02# nslookup D-T11673A
Name Server: deleted
Address: deleted

Prasad,

You Linux machine cannot resolve the host-ip address. Please refer to
http://www.daemon-systems.org/man/rshd.8.html

Try giving ip address of the server directly.
If you know the ip address and you do not have a DNS - put the entry for the host and ip address in the /etc/hosts file on your Linux machine.

Ninad

Hi Ninad,

Troubleshoot as follows.
From linux box, just do plain telnet (with same user id hat you will use for rsh) and pass. Once logged, do who -um.
Note down what you see (ip_address/hostname) in last column of above command. Put same ip_address/hostname in .rhosts file on hp-ux in home dir. The .rhost file will look as follows.

"ip_address/hostname_you_seein_who-um" "user_name"from_linux"

I have put + in the .rhost file

nslookup on linux.

nslookup ip_of_hp-ux_server
nslookup of hostname_of_hpux_server

nslookup on hp-ux server.
nslookup ip_addr_of_linux_server
nslookup hostname_of_linux_server

Is everything correct? Do both servers use same dns/nis or plain /etc/hosts file?

Sorry, While I was editing - you had already updated the post.
So it needs to be analysed if it is really a problem of host name resolution at all, because you cannot rsh using ip address as well - even though the error message shows its not able to get the host name resolved.
First thing you need to sort out is whether its rlogin problem or you are not able to access the server at all.
Are you able to ping/telnet - reach the destination server in the 1st place ?
Are routing entries proper ?

Ninad
