That's the idea, though the IKE daemon on the transport+IPIP side has
to actually offer tunnel mode or the other end will typically reject
the negotiation.

I may have been mistaken. I just pulled this information from this document
which Gregory Lebovitz from Netscreen co-authored back in 2003. On page 46
he talks about using GRE to create a virtual routing interfaces AKA tunnel
interface. I have configure route-based VPNs between a Netscreen and
FortiGate which interop just fine, which leads me to believe that they are
using the same approach to tunnel interfaces.

this could be useful for either running routing protocols over IPsec, or

No FortiGate model supported GRE in 2003, it wasn't added until 2006.

Hi Claudio,
In fact, I'm looking to had a third providers soon (maybe 4-5 weeks)
so I will start to use 3 routers. I also want to use OSPF for future

I have one interface by router dedicated to inter-router traffic

I have read your documents "Routing with OpenBSD using OpenOSPFD and

Your situation is different from mine, I am new to OSPF, and my
information may not help you any, but here it is:
I have a set up with two external routers and two internal routers. Both
external routers uplink to the same ISP unlike in your situation. They
share a carp'd external/inet IP and the status of this carp interface
(and other path/interface failures determines which external router is
used as the main uplink. My main problem setting this up is somewhat

One thing you may want to consider - booting off /dev/sd0a, and mounting the
rest as raid, and mirroring /dev/sd0a to /dev/sd1a so that you can swap a
cable and be on the alternate /dev/sd0a. This should not be a big deal,
since the root partition should not change that much, and a nightly rsync
should capture everything that changed that day, if any.
One thing about a software raid solution - you may still have to swap cables
in order to get it to boot off the second hard drive anyway (no idea ...

| Walter Haidinger | tcp fast retrans for high packet loss network
Hi list!
Simple(?) question:
How do I enable "tcp fast retransmissions"?
I've got a wireless network with a lot of interference
which results in about 30% packet loss. Fast retransmission
should help here, right?
However:
* Counter for fast retrans in 'netstat -s' is always zero.
* Nothing appropriate in 'sysctl -a'
Is TCP_FACK (commented out in conf/GENERIC) what I'm looking for?
But I've got the suspicion that TCP_FACK is outdated (dead?) code:
* TCP_FACK was reenabled in ...

| Darrin Chandler | Re: problem on setting up ntpd
I think this is different, because it's reporting "Connection Refused"
Have you enabled pf on the machine running ntpd? From your configuration
and logs it does seem that ntpd is configured and running correctly.
Best guess is that you have "block return" for that port, or as the
default. The easiest test would be to temporarily disable pf (pfctl -d)
and try your telnet test again. If that works then it's your pf rules...

[Fix your mail client, please: 72 columns or less, at least on normal

ntpd uses UDP, telnet uses TCP, so telnet isn't the proper tool for
testing if the server actually receives packets.
In addition, ntpd will only sync to a server that is itself
synchronized; this would be the delay Mispunt mentioned. If this is the
case, you should see something to that effect in the clients' logs.
You might want to investigate -s and/or one of the external timesensors

His problem was not about ntpd not syncing. At any rate, Reza, do you have
any firewalls that could be blocking the port? If you switch "listen on
192.168.1.1" to "listen on *" does that change your situation?

It will take some time before ntpd begins with syncing. Don't ask me
why, but it took a day for me before my ntpd was beginning with
syncing.

| Soner Tari | snort any interface and 2.6.1.4 mysql problem
Hi All,
I have more than one interface I need to monitor with snort. I've read
http://www.snort.org/docs/faq/1Q05/node35.html, To do that, I've created
bridge0 and added both interfaces. Since I need to assign IP addresses
to each interface, I could not just up the interfaces and add them to
the bridge. Perhaps that's the reason, but I don't see alarms triggered
with -i bridge0 (snort warns that no IP is assigned to bridge0 anyways).
Do I need to do anything else?

That's interesting. How long have you been running OBSD 4.0 on that
machine? I have the mobile version of this cpu, and my laptop started
locking up erratically (also w/o ddb) shortly after upgrading from 3.9
to 4.0. After about a week of that craziness and no way to troubleshoot
further (short of running memtest86 and 'make build', neither of which
revealed any hardware issues), I went back to 3.9, ...

What you are describing is almost certainly the i386-on-amd64 problem.
Solution is to do one of the following (in my order of preference, your
criteria may be different than mine, of course!) :
* run OpenBSD/amd64 (where this problem doesn't exist)
* wait for 4.1 (where it is fixed)
* run -current (where it is fixed)
"fixed" is probably not quite the right word, several people suspect
the PAE support was PROVOKING a real problem elsewhere, but backing

Yes, it is. Any server offering OpenBSD via CVSup should include
