Anyone using munin?

[Marc Runkel]

Trying to set up munin work with OpenBSD and was wondering if anyone had some
plugins pre-written?  In particular interface statistics but I'll take just
about anything.

Thanks,

Marc

Re: Assistance OpenBSD

Based on this email, I'd recommend you spend some of the money you've made in
the market and hire some computer expertise in your neighborhood.

The fact that you're getting stuck at adding packages and run executable
files is a big red flag for me.

It shouldn't cost more than a few hundred dollars to have someone install
Linux or *BSD for you to your specifications.

Based on your email, no amount of remote handholding is going to get you to a
working system that you'll be happy with.

As a point of reference, I went from 0 experience in OpenBSD to having a fully
configured system in  4 hours.   Just by reading the installation guide.

Let us know what area you're in and I'm sure someone can recommend someone.

Hello All,

I hope someone out there has plenty of patience and understanding.  I have
been playing
with open source for a number of years without much success.  The closest I
have come
to success is with Suse 10.2, but it is very unstable.  I have mouse freezes,
icon
disappearances, and at times the screen goes negative on me-white becomes
black etc.
I have downloaded PCBSD and DesktopBSD to where I had the desktop, but
neither
would connect to the internet.  And I could delete less from these OS than I
could from Windows.  The smaller and much more secure OpenBSD seemed to fit
the
bill.  However, I need help.  Nothing I do seems to work.  I have five books
on
FreeBSD and Absolute OpenBSD by Lucas.  I can do simple stuff like pwd, cd,
ls,
mnt CD, etc., but I cannot pkg_add from the 4.3 CD or run executable files.
What
I would like to do is add a browser and get on the web.  My computer needs
are
small; 95% of my time is following the markets.  I do not have three degrees
in
computer science, in fact I only have one degree and it is in economics.  I
do
well in the market, but BSD really has me confused.  I know the OpenBSD
community
does not like to deal with simpletons like myself, but I would appreciate
enough
help to get me started.  I have OpenBSD on my spare HP Pavilion N5250
notebook
with
an Intel pentium CPU but it is not connected to the internet.

Thank you.

Need help with OpenBGP 4.4

[Marc Runkel]

Hello,

We've recently begun testing using OpenBSD 4.4 with OpenBGP in our datacenter.
Our initial tests have uncovered an odd issue we hope you all can help us
with.  I've included our configs and relevant information below.

The summary of our issue is this:

1.) Upon starting bgpd the session between the two routers goes to established
and updates are passed.
2.) Keepalives aren't passed beyond the first exchange.
3.) After some time, the session goes to IDLE on both routers.
4.) The session tears down if we either issue a bgpctl command (like show
summary or show neighbors) or wait 240 seconds after the initial connect.
5.) The routers then reestablish connections but they drop again.
6.) The exact same setup works fine with OpenBGP 4.3.

Here's what we've found.  If we modify session.c at line 405 (timeout = 240;
/* loop every 240s at least */) to some number lower than our holdtime, it
works.   Adding debugging code to the code after that line shows us that the
code doesn't get processed again after the intial setup unless the timeout
value is reached or some bgpctl statement is excecuted.

We've replicated this error in two different test environments.  The error
causes sessions to be torn down anytime a 4.4 bgpd is used. (ie 4.4 - 4.4 and
4.4 - 4.3).

Please let me know if you need any additional information from me.

Thanks so much,
