This issue started happening after i changed router.
This is the scenario:
Windows7 Host
Ubuntu 10.04 Guest (VirtualBox)
Ubuntu 10.04 remote server
What i used to do is run a very basic rsync command:
rsync -avz --delete /local/path/ username@host:/path/to/remote/directory
This worked perfect until i did change adsl provider, and i changed router aswell: now, this happens:
rsync on Ubuntu Guest is not working anymore (to any random server), if using this new router
rsync on Ubuntu Guest is WORKING, if i switch back to old router
i tried a new virtual box ubuntu install, and the command is WORKING
with both the routers
So, the not-working-combo is oldUbuntu + newRouter.
To get things worst, i can state that (on the not-working ubuntu)
i ping the remote host
plain ssh connection to the remote host is working fine (i can auth, connect, and do stuff on the remote host)
scp is NOT working (this is just a further thing i tried)
This is the console output of the execution, with ssh verbose set to vvvv:
root@client:~# rsync -ae 'ssh -vvvv' /root/test-rsync/ {username}@{hostname}:/home/{username}/test/
