SInce you're doing it by SSH (presumably) and not running Snort as root (presumably) and not allowing direct root remote logins (presumably), you'll need to do something like this after adding the account (snort) into sudoers:

o       Upload Settings tab

o       Upload Protocol = SFTP port 22

o       Upload Directory = /etc/snort

o       Configuration File = snort.conf

o       Test Connectivity Command = uname –a;id (pre-filled in)

                               Use Compression – unchecked

o       Authentication tab

o       Username = snort

o       Authentication Mode = Password

o       (Enter the password twice)

o       Restart Settings tab

o       Restart after Upload = checked

o       Restart Method = Script via SSH

o       Script = sudo /etc/init.d/snortd restart

o       Click OK

HTH,
