ftp and ssh weirdness
i've just setup my desktop (ubuntu 8.04) to run vsftpd and sshd. i have two laptops, both running linux. on one laptop i can connect to the desktop via ftp and ssh and everything works fine. so i don't think there's a problem with the server.

on the other laptop i can't connect to the desktop via ftp or ssh using the command line. however, if i use the gui interface gftp (gnome ftp) i can ftp to my desktop. this seems weird. ssh still doesn't work with gftp.

here's verbose output from ssh on the laptop that doesn't work, ftp doesn't give back anything in verbose mode. both protocols hang after inputting the password.

wireless vs wired
ok, on a hunch i plugged my laptop into my router (wired connection). now i can ftp and ssh to the server just fine.

however, when i switch back to wireless i have to same problems, ftp and ssh hang after asking for the password.

do i need to change something on the router.......i'm using wpa2 personal encryption if that makes any difference.

hmm..... i'll try it with no encrytion, then wep, then wpa.....

encryption doesn't matter
ok, encryption doesn't matter, doesn't work if unencrypted.

only wired vs wireless. any ideas?

Solved!!!

I found that both of these two settings had to be made to my router's config: Enable Wireless QOS under Applications & Gaming/QOS, and Disable Upnp under Administration/Management (the answer to "Why?" would only be a guess).

Now it works.
