Red Hat Bugzilla – Bug 49610
Last modified: 2008-05-01 11:38:00 EDT
Description of Problem:
Current "Fairfax" provides in /etc/issue and /etc/issue.net "fixed"
login banners with a string 'Kernel \r on an \m'. What, on earth, give
you an idea that a tty supplying program will be able to interpret
these escapes? If for a "regular" console there is a fair chance that
this will be mingetty, although this is far from given, it is quite
unlikely that whatever used on serial lines or network connections will
have this ability.
In particular if you will telnet to a machine running Fairfax to itself
you will be greeted by the following:
Escape character is '^]'.
Red Hat Linux release 7.1.92 (Fairfax)
Kernel \r on an \m
"Old hands" will shrug and replace; often they run custom banners anyway.
Newbies will be terminally baffled. Note that "fixing" /etc/issue.net
still does nothing for serial connections or alternate getty programs.
That was a telnet-server bug, which has since been fixed.
FWIW, everything in the distro (telnet-server, mingetty, mgetty, agetty)
all support the same sequences.
Upgrading from 7.0 to fairfax beta2 causes /etc/issue not to be updated, thus resulting in the login banner to display kernel version 2.2.16-22, /proc/version showing 2.4.6-2.
