Version 5.6.1  [V5-STABLE] (rgerhards), 2010-11-24

  • bugfix(important): problem in TLS handling could cause rsyslog to loop in a tight loop, effectively disabling functionality and bearing the risk of unresponsiveness of the whole system.
    Bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=194
  • permitted imptcp to work on systems which support epoll(), but not epoll_create().
    Bug: http://bugzilla.adiscon.com/show_bug.cgi?id=204
    Thanks to Nicholas Brink for reporting this problem.
  • bugfix: testbench failed if imptcp was not enabled
  • bugfix: segfault when an *empty* template was used
  • Bug: http://bugzilla.adiscon.com/show_bug.cgi?id=206
    Thanks to David Hill for alerting us.

    Thanks varmojfekoj for the patch.

Installing RSyslog 5 on RHEL 4 / 5

By Adiscon SupportPosted on Posted in FAQTagged , , ,

To have rsyslog working correctly on RHEL 4 or 5, some conditions have to be met. The method described has been tested with rsyslog 5.7.1.

First of all compile and install the dependencies.

  • gnutls-2.8.6.tar.bz2
  • libgcrypt-1.4.6.tar.gz
  • libgpg-error-1.9.tar.gz
  • libtasn1-2.2.tar.gz

After that, you can install rsyslog using the following commands:

./configure PKG_CONFIG_PATH=/usr/local/lib/pkgconfig --enable-gnutls
make
make install

It could happen, that the install might complain about gnutls.pc. Simply comment out the URL found near the start of the file /usr/local/lib/pkgconfig/gnutls.pc.

Credit for this find goes to Forum member Johann Reinhard (johannreinhard).
