tftp server giving following error

[Ashish Palkhiwala]

I have a perl script on HP-UX 10.20,which is supposed to copy running config file from cisco routers to tftp server. but for some reason I am getting following error when running " copy run tftp" cmd.

TFTP:error code 2 received - Access violation.
%Error opening tftp://IPaddressof tftp_server/file name (undefined error).

What should I do to make sure tftp server is running properly. This script used to work fine.

I started getting this error after I rebooted my tftp server. I have tftpd running with tftp user defined in /etc/passwd. and home dir for the user.
I have attached my perl script here please help me.

Thanks
Ashish
