[Perl-unix-users] rcp says permission denied , or unknown host

[PRADEEP GOEL]

system("rcp $workdir/installP.pl $remhost:installP.pl");  says permission denied    i am not  much familier with rcp    i have tried several combination such as applying "  root@ "  before $workdir  etc sometimes it says permission denied or else it says unknown host    machine on which i am writing script , i am a user not root  at many places scripts assume root so i put " -l root" with rexec or remsh  not know about rcp -      system("rcp $workdir/installP.pl $remhost:installP.pl");   " $remhost root " entry is there in .rhosts  see if anyone can tell me the possible causes.    Regards  Pradeep
