[Message part 1 (text/plain, inline)]

Package: x2goserver Version: 4.01.19 Server Fedora 21 x2goserver-4.0.1.19-1.fc21.x86_64 Client Fedora 20 x2goclient-4.0.3.1-1.fc20.x86_64 I had this working fine, and then one day the client would hang in a greyed out manner waiting to connect. Several hours of tracing through the scripts, I learned the server x2gostartagent script was simply infinite looping through sessions and /usr/lib64/x2go/x2gosqlitewrapper.pl insertsession was rejecting them all. I suspected the problem may be when I changed my user id on the server from alpha-numeric to all numeric... Yes I know traditional UNIX/Linux user ids are supposed to start with at least 1 alpha character, but working for a large corp where MS Active Directory runs everything, they have successfully standardized all Windows and Linux user accounts to 6 digit numerics. You don't have to convince me this was a BAD idea, but way above my pay grade. So when I changed my server to match (and yes Fedora will accept a numeric user id even without AD authentication, but it will warn against it), the failure started. One more test I ran a connect as 'root' and it connected right away, so I knew where the problem was. Digging through x2gosqlitewrapper.pl I noticed a lot of perl regex and found the sanitizer function, line 67. When I replaced it with if ($string =~ /^([a-zA-Z0-9\_] .... <adding the 0-9 to the match> everything started working again. Diff file attached.
