Subject: Cannot connect to epel5 servers: Undefined subroutine &main::LOG_UPTO

Date: Sat, 3 Jan 2015 10:49:49 -0500

Package: x2goserver
Version: 4.0.1.18
Severity: grave

Server: CentOS 5.11 64-bit
Server distro's version of Perl: 5.8.8-43.el5_11

Client: x2goclient 4.0.3.1
Client OS: Windows 8.1 64-bit

While I was verifying the fix for #699, I noticed that whenever I
attempt to connect to my CentOS 5 server, I get the error:
Connection failed
Undefined subroutine &main::LOG_UPTO called at
/usr/bin/x2golistsessions line 35.

This bug prevents X2Go Server from being used at all on epel5 distros
(RHEL 5, CentOS 5, SL 5, OL 5).

It appears that the cause is that the LOG_UPTO() function is not
available on CentOS 5's version of Perl, 5.8.8. It is available on
CentOS 6 (Perl 5.10.1), hence why my CentOS 6 system is not affected.

Subject: Actually a packaging problem

Date: Sat, 3 Jan 2015 12:08:18 -0500

This is actually a problem with our packaging. A 3rd-party RPM exists
to provide a newer version of Sys::Syslog that is sufficient, and this
is stated on the wiki.

The bug is that yum is not informing the user of the need to install
that newer version. The wiki states the following, and the 2nd
sentence is false:
"One approach is to download required packages manually. Yum will tell
you what is needed, when you ask it to install x2goserver."
http://wiki.x2go.org/doku.php/doc:installation:x2goserver?&#rhel_5

For reference:
The RPM that I used (and tested successfully) was:
http://flexbox.sourceforge.net/centos/5/x86_64/perl-Sys-Syslog-0.27-1.el5.x86_64.rpm
Apparently 32-bit users should use this noarch RPM instead:
http://flexbox.sourceforge.net/centos/5/i386/perl-Sys-Syslog-0.27-1.noarch.rpm

the same issue already was reported as #563... attaching #563 to #714
