Running ActivePerl 5.6.1 and using the net::telnet module i get the following error: Argument "" isn't numeric in numeric gt (>) at C:/Perl/lib/Net/Telnet.pm line 2569. The script generating this is : #!perl -w use Net::Telnet; $telnet = new Net::Telnet ( Timeout=>10, Prompt => '/bash\$ $/'); $telnet->open("host"); $telnet->login('username','password'); #$telnet->cmd('/drv02/pd/temp/perl/sfGraphic/log/sigtestgen.pl'); $telnet->cmd('logout'); any idea's on how to fix this? Thanks for any help
