Logcheck devel - Jul 2004 - Bug#260743: logcheck-database: dhcp rule updates for failover support

Package: logcheck-database
Version: 1.2.23
Severity: minor

Hi,
a couple of minor corrections to the dhcp rule sets:
First of all, the hostname matching parts need to include the "._-"
signs (maybe . is not needed but it might be).
Then when using failover, log lines of type DHCPDISCOVER and DHCPREQUEST
may be entailed by the string ": load balance to peer
<somestring>".
I've also had the message ": wrong network." appended, when a
client
requested an ip adress out of a different domain, which will result in a
DHCPNAK. This is a common case with WLAN users i think.

I also added rules for dyndns support by dhcpd.

The modified rules are:

# Dyndns support for DHCP
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ dhcpd: [Aa]dded (new )?(forward|rewerse) map
from [._[:alnum:]-]+ to [._[:alnum:]-]+$
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ dhcpd: Can't update forward map
[._[:alnum:]-]+ to [.0-9]+: no such RRset$
# Added load-balancing statements and hostname characters ._-
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ dhcpd: DHCPDISCOVER from [:[:alnum:]]+
(\([._[:alnum:]-]+\) |)via [[:alnum:]]+(: load-balance to peer [^ ]*|)$
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ dhcpd: DHCPREQUEST for [.0-9]+ (\([.0-9]+\)
)?from [:[:alnum:]]+ (\([._[:alnum:]-]+\) )?via [[:alnum:]]+(: load-balance to
peer [^ ]*)?$
# added ._- to allowed chars for hostname
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ dhcpd: DHCPACK on [0-9.]+ to [[:alnum:]]+
(\([._[:alnum:]-]+\) )?via [[:alnum:]]+$
# if you are paranoid, you'll want to skip these rules:
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ dhcpd: DHCPREQUEST for [.0-9]+ (\([.0-9]+\)
)?from [:[:alnum:]]+ (\([._[:alnum:]-]+\) )?via [[:alnum:]]+: wrong network.$
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ dhcpd: DHCPNACK on [0-9.]+ to [[:alnum:]]+
via [[:alnum:]]+$

Thanks for your good work.
I'm expecting to get more rule updates soon. Should i submit them here or to
some mailing list?

Hi,
sorry, the rules still had a couple of weaknesses.
I'll post new rules using [.0-9]{7,15} for IPs, [:0-9a-f]{17} for MACs
etc. soon - after i've verified with a couple of reports that these
rules catch all my new log lines.

I'll also attach a pptpd rule file, if you want to.

Greetings,
Erich Schubert
