Strange- RCP works every other time

Jeffro_1 — Thu, 04 Mar 2010 12:43:21 GMT

This just started to happen.
When I use rcp to copy a file from one server to another, every other time I execute the rcp command I get the error:
remshd: login Incorrect

As a example if I execute the command

rcp test.file server2:/db/tmp (It works ok)

The very next time I execute the same command:
rcp test.file server2:/db/tmp I get the error: remshd: login incorrect

Perhaps someone has associated more than one IP address with the name "server2" and a round-robin DNS server is flipping the order?

What happens when u run it again, yes DNS can be lil issue but it sounds strange :)

Do it with IP, and run nslookup for this server for sometime to see if IP is the cause.

On server2, append the IP address in addition to the hostname in .rhosts. If it works reliably, you have DNS problems.

I did append the IP address in addition to the hostname in .rhosts and it worked reliably. If I have a DNS problem and suggestions on how to proceed to resolve.

I am working on a HP server running HPUX

Thanks.

You have to take up the problem with your DNS administrator. HP-UX is simply asking the DNS server to translate a hostname to an IP address. Apparently it is not always working correctly.
