RHBA-2011:1596 - Bug Fix Advisory

Topic

An updated net-tools package that fixes various bugs is now available for Red
Hat Enterprise Linux 6.

Description

The net-tools package contains basic networking tools, including ifconfig,
netstat, route, and others.

This updated net-tools package includes fixes for the following bugs:

• Prior to this update, the "hostname -i" command failed to display related

network addresses when the hostname was not included in the /etc/hosts file. The
"hostname -f" command had the same issue with Fully Qualified Domain Names
(FQDNs). To fix this issue, new "--all-fqdns" (or "-A") and "--all-ip-addresses"
(or "-I") options have been implemented for the hostname command. These options
are independent on the /etc/hosts content. The "hostname -I" command now
displays all network addresses for all configured network interfaces, and the
"hostname -A" command displays all FQDNs for all configured network interfaces
of the host. (BZ#705110)

• The "netstat -p" command output incorrectly displayed a number in the

PID/Program name column instead of the program name. The code has been modified
to fix this issue, and netstat now shows the correct program name in this
column. (BZ#725348)

• The netstat utility truncated IPv6 UDP sockets when the "--notrim" (or "-T")

option was specified. This update fixes the issue, and whole IPv6 addresses are
now displayed for UDP sockets when using netstat with this option. (BZ#732984)

• The route(8) manual page now includes an explicit description of the "mss M"

option. (BZ#680837)

• The SYNOPSIS section of the plipconfig(8) manual page and the usage output of

the plipconfig command have been modified to show correct plipconfig options.
(BZ#694766)

All users of net-tools are advised to upgrade to this updated package, which
resolves these issues.
