rcp problem

[Frederic Sevestre]

Hi,
When I am trying to copy a file from a server A to the server B using rcp, there is the following error :
remshd: Couldn't look up address for your host
I tried it using the hostname or the IP address with the same result.
ftp works fine, ping from a server to a other works fine, rcp from B to A is ok.
Any idea ?

If you are doing rcp as user xyz: add
an entry on serverB's xyz homedirectory .rhosts file
serverB:$xyz/.rhosts -> add the entry serverA xyz .

IF the .rhosts file is not there, create
it with this entry.

Hi,
add the hostname/ip of host B in /etc/.rhosts of host A.

Hi:

Have a look at the man (4) pages for ' hosts.equiv'. You will find access rights are provided or denied for 'rcp' 'remsh' or 'rlogin' by this mechanism.

Hi,

.rhosts or hosts.equiv are the two files you should configure for rcp,remsh etc.
Try using IP address if host name doesn't work

Goodluck,

hi Fred,

Try hostname and ip resolution from both the servers. You may have a bogus entry somewhere, either in /etc/hosts or in your DNS. Do a "nslookup" from each of the servers and try the hostname and ip resolution for that server and the other server to which you are doing rcp.

Hope this helps.

hi,
Thanks for all guys.
It was a problem with the DNS server (an alias not set).
