When the proxy.di.unipi.it does not work, open a shell, ssh to a Dept. machine where you have a login with a

  ssh -D 1080 username@machine.di.unipi.it
  

then set up you firefox browser to use SOCKS proxy on port 1080 (or any other number you used in the ssh) via 127.0.0.1

Don't forget to remove the proxy from the settings (this is the Firefox-Preferences-Advanced-Network window) *before* actually killing the SSH, otherwise Firefix my refuse to open again the network preferences.

After we moved the email to central admin, we got email addresses in the form

name.surname@unipi.it

Unfortunately, we used the old addresses

nickname@di.unipi.it

to register in a number of mailing lists, web sites etc. When sending to mailing lists you registered with the old address, messages result as sent from the new one and get blocked. In Thunderbird, you may simply edit the “From” field and force it to the old address. Being an alias, this is accepted by our mailer and guarantees messages are accepted on the mailing lists where you've been registered with the “old” addresses.

At Dept. we are moving wired Ethernet ports to run 802.1x authentication. On Ubuntu 16.04, just open the network settings dialog, pick up the secuity tab and set parameters as you did for accessing Eduroam. Ideally a

sudo service network-manager restart

should be enough, but I verified you have to reboot to have the interface working with the new configuration.
