some people have pointed out that the "map" probably isn't your problem, so i'll skip that and point out what i think may be your problem.

Net::FTP::Recursive is built ontp of Net::FTP .. if you look at the docs for that, you'll find this...

Passive - If set to a non-zero value then all data transfers will be done using passive mode. This is not usually required except for some dumb servers, and some firewall configurations. This can also be set by the environment variable FTP_PASSIVE.

I have no idea if Novell qualifies as a "dumb server" ... but it sounds likely. The only problems i've ever had in writting scripts that involve FPT have been from not using FTP_PASSIVE, or from servers on connections that suck so bad they died continuously)

If passive mode doesn't work for you, then it would be usefull to see the "Debug=>1" output from the script when -- both when talking to the Novell server, and the serrver you got it to work on. If you post it, some friendly Monk might spot your problem.
