Re: linux isakmpd with freeswan - ADD: No buffer space available

Are you trolling?  This is a list for OpenBSD, not Linux.

BTW, check memory or hard drive usage.

AES should be probably protected by #if openssl >= 0.9.7

just remove the AES define from the features list in the makefile.

You'd ask on misc <at> 

or "man mfs"

No buffer space available

Hi,

I'm having trouble with qos and openbsd3.3, basically I do ACKs 
prioritizing (www.benzedrine.cx/ackpri.html) and when there is a lot of 
outbound traffic (128kbps is the max on my adsl link), the network 
traffic stops after a couple of minutes, except already established 
connections. If I do a ping I get this message "No buffer space available".

I've stfa and there seem to be other people with same problem, so as 
suggested in other posts I've tried different NICs and increased network 
buffers via sysctl but it does not make any difference.

When the problem occurs, if I reload the pf rules with pfctl -f 
/etc/pf.conf if works again for a couple of minutes. If I remove qos 
from the rules, there is no problem, so it has definetely something to 
do with qos!

Any ideas ?

Regards,
Alexandre

Re: No buffer space available

Getting ENOBUFS is intended behavior--it is how altq indicates
to userland that the queue is full.

It sounds like your queue rules in pf.conf are the problem.  You
have to be very careful when prioritizing things that you don't
lock out important stuff (like outbound ICMP or DNS for example).
You probably want several priority levels.

Re: No buffer space available

That has solved the problem, looks like my qos rules were too extreme :)
Thanks.

Panic: ffs_alloccg: map corrupted

My system paniced a couple of times in a couple of days with the 
following error: "ffs_alloccg: map corrupted"!

Furthermore, I have noticed some strange things occur simetimes: a 
particular byte of a give file changes!

The system is an OpenBSD 3.4 i386 (a checkout of OPENBSD_3_4 of a couple 
of days ago).

What does it means?

Thanks.

P.S.
Here it is the dmesg:

Re: Panic: ffs_alloccg: map corrupted

Hmmm - it may be worth running a memory test for a day or so, see
http://www.memtest86.com/

(I usually make this a boot option on my x86 machines, & run it if
anything unexpected starts happening).

Dave.

I have run it for a while but no error was found...

If nobody else have problems with FFS under 3.4, then could it be a 
problem with the gdt driver (software or hardware)?

Thanks.
