RE: SNMP problems with an ISDN connection
This is a little off topic... but,
In looking to use SNMP more, what software do you use for snmp reporting and
monitoring. I'm interested in trying some things out since I haven't used
this much yet. Any suggestions for more information?
thanks.

We use a lot of SNMP here (or at least we try to), and in my limited
experience with SNMP on Linux I've found the UCD SNMP packages to be
more useful than the CMU packages (the UCD packages are in potato).
If you don't want to upgrade to potato yet, grab the UCD SNMP source
deb(s) from your friendly neighborhood debian mirror and build your own
debs. Works for me ...
To build packages (a quick un-asked for extra; sorry if this offends):
# (Uh, I used my local mirror :)
wget
http://debian.midco.net/debian/dists/potato/main/source/net/ucd-snmp_4.0.1.o
rig.tar.gz
wget
http://debian.midco.net/debian/dists/potato/main/source/net/ucd-snmp_4.0.1-5
.diff.gz
wget
http://debian.midco.net/debian/dists/potato/main/source/net/ucd-snmp_4.0.1-5
.dsc
# extract the source
dpkg-source -x ucd-snmp_4.0.1-5.dsc
# build it
cd ucd-snmp-4.0.1
dpkg-buildpackage -rsudo -uc -B
I just tried all this on a slink system, you should end up with the
following debs:
libsnmp4.0-dev_4.0.1-5_i386.deb
libsnmp4.0_4.0.1-5_i386.deb
snmp_4.0.1-5_i386.deb
snmpd_4.0.1-5_i386.deb
