New subject: Bug#1131: Bug#1131: x2gosqlitewrapper - Session not opening when username starts with a number

9 Jan 2017


      Package: x2gosqlitewrapper
Version: 4.0.1.20-3.4
When a username starts with a number, the session on the client computer will not open, after connecting to the server.
The problem lies within x2gosqlitewrapper.pl in the sanitizer function.
This function will return 0 in the  $type eq "x2gosid" case, when the username starts with a number.
My workaround is to add a 0-9 in the line number 67 of x2gosqlitewrapper.pl
diff x2gosqlitewrapper.pl x2gosqlitewrapper.pl.original
67c67
<                       if ($string =~ /^([a-zA-Z0-9\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-([\d]{2,4})\-([\d]{9,12})\_[a-zA-Z0-9\_\-\.]*\_dp[\d]{1,2}$/) {
...
                  if ($string =~ /^([a-zA-Z\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-([\d]{2,4})\-([\d]{9,12})\_[a-zA-Z0-9\_\-\.]*\_dp[\d]{1,2}$/) {
elsif ($type eq "x2gosid") {
$string =~ s/[^a-zA-Z0-9\_\-\$\.\@]//g;
if ($string =~ /^([a-zA-Z0-9\_\-\$\.\@]*)$/) {
$string = $1;

                   if ($string =~ /^([a-zA-Z\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-([\d]{2,4})\-([\d]{9,12})\_[a-zA-Z0-9\_\-\.]*\_dp[\d]{1,2}$/) {


                   if ($string =~ /^([a-zA-Z0-9\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-([\d]{2,4})\-([\d]{9,12})\_[a-zA-Z0-9\_\-\.]*\_dp[\d]{1,2}$/) {
                           if ((length($1) > 0) and (length($1) &lt; 48)){
                                   return $string;
                           } else {return 0;}
                   } else {return 0;}
           } else {return 0;}
   }


I  am using a OpenSuSE Leap System with x2goserver Version 4.0.1.20-3.4
