RHBA-2015:2397 - Bug Fix Advisory

Topic

Updated conman packages that fix two bugs and add one enhancement are now available.

Description

ConMan is a serial console management program designed to support a large
number of console devices and simultaneous users. It currently supports
local serial devices and remote terminal servers (via the telnet protocol).
Its features include:

• mapping symbolic names to console devices
• logging all output from a console device to file
• allowing clients to join or steal console "write" privileges
• executing Expect scripts across multiple consoles in parallel
• supporting monitor (R/O), interactive (R/W), and broadcast (W/O) modes of console access

This update fixes the following bugs:

• Before introducing the 'systemd' manager, limits for the conman service were able to be configured in the '/etc/sysconfig/conman' file. However, after migrating to 'systemd', '/etc/sysconfig/conman' was no longer used and was therefore removed. With this release, a new variable LimitNOFILE=10000 has been added to the 'systemd.service' file. Note that it is not enabled by default and therefore is commented out. Instructions on how to edit the 'conman.service' file are located in the systemd.exec(5) manual page. (BZ#1035228)
• In its original implementation, exceeding the limit on number of SOL IPMI consoles caused the conman package to crash on start. This has been fixed along with the added benefit of SOL support. As a result the conman package no longer reports 'Unable to start IPMI SOL engine' when the limit is exceeded. (BZ#1244189)

In addition, this update adds the following enhancement:

• Enhancements to conman include enabling the IPMI SOL support. (BZ#1084116)
