Unaccent an entire directory tree with files.
This command changes all filename and directories within a directory tree to unaccented ones. I had to do this to 'sanitize' some samba-exported trees. The reason it works might seem a little difficult to see at first - it first reverses-sort by pathname length, then it renames only the basename of the path. This way it'll always go in the right order to rename everything. Some notes: 1. You'll have to have the 'unaccent' command. On Ubuntu, just aptitude install unaccent. 2. In this case, the encoding of the tree was UTF-8 - but you might be using another one, just adjust the command to your encoding. 3. The program might spit a few harmless errors saying the files are the same - not to fear.

back ssh from firewalled hosts
host B (you) redirects a modem port (62220) to his local ssh. host A is a remote machine (the ones that issues the ssh cmd). once connected port 5497 is in listening mode on host B. host B just do a ssh 127.0.0.1 -p 5497 -l user and reaches the remote host'ssh. This can be used also for vnc and so on.
