Can't find remote host with ssh connect attempt to remote server

Using Linux and remote ssh command (I've placed my public ssh key on the remote server to allow non-password prompted connects)
The following command runs fine from the Linux command line:

ssh root@remoteIP /usr/bin/ls

However, when the following is called from my perl script:

system("ssh root@remoteIP /usr/bin/ls");

Perl reports:

ssh: Could not resolve hostname root.remoteIP: Name or service not known

(remoteIP is the real IP address of the remote computer. Obviously, I need to tell Perl how to resolve the address?)

Dont think you meant interpolate the var @remoteIP. Its always helpful print out the command you mean to execute.
Perl:
my $cmd = 'ssh ...';
print "'$cmd'\n";
system($cmd);

Double-check the server address or hostname you're using. Ensure it's accurate and matches the server you're trying to connect to.
