    firewall causing ftp problems

    i have a linux box serving as a cable modem firewall / router. but ive encountered a problem with FTP. when i connect to an FTP server and attempt to list a directory's contents, it tells me its unable to create a data connection....i assume this is because my firewall is blocking the port used for this data connection...does FTP just pick a random unused high port or can you specify which one for it to use so i can unbock the port?


    damn firewalls.

    Don't know much about firewalls, but from what I do know, it sounds as if you have to tweak your settings. I would look into your ftp settings and make sure you have enabled downstream ftp. Otherwise you can upload all day, but you don't get to get a thing, not even directory listings! ;D
