ok so i have two PCs: one with ip 192.168.121.5 (dot5)
and other with ip 192.168.121.154 (dot154)

so i first create a folder test154 on dot154, initialize git, add, commit
now i create a folder on test5 on dot5, initialize git, pull from dot154 using this command:
         git pull ssh://gen@192.168.121.154/~/test154/

i have all files from test154 in test5.
now i delete everything in folder test5 using: 
         rm -rf *
and from git too:
         git rm -r *
         git add .
         git commit -m"asdf"

so now i have nothing in test5. now i pull again from the same command.
but nothing is transferred. Already-up-to-date msg comes.
Dunno wat to do?

using apt-ge git-core it says you have the latest version.
