Re: GRE over IPsec
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. I have yet to get this to work between an OpenBSD box and a FortiGate/Netscreen. I ...

Re: GRE over IPsec
interesting; if my understanding of this and the RFC that the referenced 'touch' draft was published as (rfc3884), at one end you can configure one side in *transport* mode carrying ipip encapsulated packets - gif(4) with net.inet.ipip.allow=1, afaict - and the other side in tunnel mode as usual. this could be useful for either running routing protocols over IPsec, or for redistributing IPsec "routes" into an IGP (the latter being something I've been wondering about how to handle in some way ...

Re: carp, ospf can't see carp state
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 expension. I have one interface by router dedicated to inter-router traffic (iBGP, OSPF and of course the data to the other upstream provider) I have read your documents "Routing with OpenBSD using OpenOSPFD and OpenBGPD" and "OpenOSPFD" (http://www.networx.ch/OpenOSPFD%20-%20Presentation.pdf) and I'm under the impression that is possible ...

Re: carp, ospf can't see carp state
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 similar to yours in terms of ...

Re: Problem: Raid mounting root as read-only, and not fr ...
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 ...

Re: fileserver lockups: no ddb
best guess right now is that it'll be fixed by a 4.1 upgrade based on this 4.0 -> 4.1 change: "Revert PAE pmap for now, stops freezes commonly seen on amd64 machines running in i386 mode."

fileserver lockups: no ddb
have had this machine, with bioctl and dmesg posted below, lockup on me both this saturday and last weekend as well. its console is com0 by default and there is no serial console output (e.g. ddb). when viewing it over KVM (/dev/ttyC0) the cursor keeps blinking but it won't receive any kb input. none of the logs contain useful clues. the machine runs samba-3.0.21bp4, nrpe-2.5.2 and is a kerberos KDC. have not yet tried upgrading to current and would prefer to go release-to-release on this ...

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 ...

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... -- Darrin Chandler | Phoenix BSD User Group | ...

On 4/8/07, Reza Muhammad <rezmuh@razorblade.or.id> wrote: The NTP protocol is only used with UDP and not with TCP. As such, you can't connect to it with telnet. To see whether the server is listening for UDP packets on port 123, use "netstat -f inet -na | grep "udp.*\.123". If it is indeed listening and yet ntpdate doesn't work on the clients, then check your PF rules to verify that the packets are being let through in both directions. Philip Guenther

problem on setting up ntpd
Hi all, I was just trying to setup an ntpd server for my home network so it could sync with each other.

Re: problem on setting up ntpd
[Fix your mail client, please: 72 columns or less, at least on normal text.] 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 (nmea(4) and ...

Re: problem on setting up ntpd
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?

Re: problem on setting up ntpd
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.

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? Using 0.0.0.0 or any as ...

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.

Re: fileserver lockups: no ddb
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 out the PAE support seems to ...
