remshd: Couldn't look up address for your host

Hi,
I am not sure why this error is coming. Some times this error is coming and some times it is NOT. I don't know what to check and what is causing this issue. Any idea why this error is coming and what to check?
Thanks,

Re: remshd: Couldn't look up address for your host

Hi

What is your server's ip address?
What is the ip address of your DNS server?

Are they on different subnets?

Sounds like they are and you probably see this error when there's a lot of traffic on the network

You can either supplement your /etc/hosts file with more entries or move your DNS server into your subnet or vice verse.

Re: remshd: Couldn't look up address for your host

Check the following, /etc/hosts.allow on the remote server. Also did you change the IP address / hostname in DNS/NIS (if you're using either).


Are you using the fully qualified domain name (FQDN, hostname.domainname) in the .rhosts file or are you using the alias. Finally when you do a nslookup on the IP address, do you get the FQDN or the alias? If you get the alias, then that's what you need to use in the .rhosts file, if you get the FQDN, then use that. Check these on both the local and remote machines.
Problems are common to all, but attitude makes the difference
