1.170.1. RHBA-2011:0817: system-config-network bug fix update
Updated system-config-network packages that fix a bug are now available for Red Hat Enterprise Linux 5.
The system-config-network packages provide network configuration utilities for both the graphical user interface and command line. These utilities support Ethernet, wireless, IPsec, Token Ring, ADSL, ISDN, and PPP.
* When the /etc/hosts configuration file contained an invalid entry (for example, an IP address without a hostname), an attempt to run the system-config-network utility failed with a traceback written to standard error. This update corrects the utility to verify that the /etc/hosts file does not contain erroneous lines. As a result, when an invalid entry is present, a warning message is displayed, and system-config-network starts as expected. (BZ#492915
All users of system-config-network are advised to upgrade to these updated packages, which resolve this issue.
