I am aware of sftp, only for the specific computer I am trying to connect to, when I try to connect over sftp the connection locks up. I can't connect directly back to my computer since I am conection through the isp NAT and an extra home NAT which resalts with my computer having to reachable address as far as the remote is concered. The remote computer only allows conections over ssh, so I am looking for a way to tunnel some kind of file send protocol (ie ftp, tftp) over ssh in the reverse direction, where I can run any server I want. I need to transfer files in both directions, and I guess I can write a program to do this, but I'd rather not rewrite ftp. can tftp both send and recieve files and will it run over the reveresed ssh connection, or any other ideas on how to achive what I am trying to do? thanx ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
