This probably isn't your problem, but that seems quite a lot of networks
to be natting behind a single IP especially with the default port range
(50001:65535). if you've got a lot of active natted states, the
search for a free port could involve a bunch of state searches
(pick a random port, lookup state to see if it's used, then search
sequentially for a free port looking up state each time).
So if you do have a lot of states you might want to either add more IPs
or increase the port range available (e.g. pass...nat-to $ext_if \
port 2:65535) and adjust the net.inet.ip.port* sysctls for
connections coming from the firewall itself (to make sure you have
some free ports which don't conflict with the range used by that
PF rule).
No, thats not a real issue, since there may be alot of netowrks/ips in
those nats, but there is only 1-2 active hosts on those networks.

239.255.170.187.in-addr.arpa domain name pointer
dsl-187-170-255-239-dyn.prod-infinitum.com.mx.
Our system has no relation at all with this ip.
But somehow our NAT translation at random intervals, decides to
redirects traffic to that ip instead of the intended destination.
Sofar we have primarily noted the problem towards 130.244.190.46 and
130.244.190.42, that are our providers sip gateways.
Since the only thing beeing used on the connection is a PBx solution.
A google on that perticular IP, gives a simular dmesg error output in
this post:
http://www.mail-archive.com/misc@openbsd.org/msg95116.html
But in his case, the system hangs, our system keeps on going.
And instead interferes with the connection of phonecalls.
since the problem was discovered ive set up pf to log the first packet
of every new state,
and then that is tcpdump thru tcpdump -n -e -ttt -s 1600 -vvv -XX to a
ascii log using the

Considering this snippet alone, there's no indication of a problem
with PF; it looks to me like 192.168.230.101 is itself sending
packets to 187.170.255.239, maybe your PBX software is confused.
I would look at packets on the inbound/outbound interfaces rather
than pflog and see what addresses show up there. (tcpdump -Xs1500
-nire0 port 5060 or something, and same for bge0).
The xxx.255.239 makes me wonder if the PBX is trying to do some
multicast thing and getting the byte-order wrong (239.255.xxx would
be a multicast address).
I have been taking a closer look on the packets, both on the external
bge0 itnerface,
and the internal re0.
And the problem happens when the packet transfers thru pf from bge0 to re0.
using the rule

This probably isn't your problem, but that seems quite a lot of networks
to be natting behind a single IP especially with the default port range
(50001:65535). if you've got a lot of active natted states, the
search for a free port could involve a bunch of state searches
(pick a random port, lookup state to see if it's used, then search
sequentially for a free port looking up state each time).
So if you do have a lot of states you might want to either add more IPs
or increase the port range available (e.g. pass...nat-to $ext_if \
port 2:65535) and adjust the net.inet.ip.port* sysctls for
connections coming from the firewall itself (to make sure you have
some free ports which don't conflict with the range used by that
PF rule).
No, thats not a real issue, since there may be alot of netowrks/ips in
those nats, but there is only 1-2 active hosts on those networks.

Sure. Not to mention it came with source code, which you only got from ATT if you had a source license, and those were*expensive*. I was fortunate enough to work for a company that had exactly that source license during the 1980:s, and I learned a*lot* just by reading the code.

I mean, I can assign to them, but if vlan40 is assigned to hme2 and hme2 failes, than vlan40 will be down and hosts in vlan40 are unreacheable. So: ifconfig hme2 up ifconfig hme3 up ifconfig vlan40 create ifconfig vlan40 vlandev hme2 ifconfig vlan40 inet 192.168.240.1 255.255.255.0 ifconfig vlan40 up ifconfig bridge1 create ifconfig bridge1 add vlan40 ifconfig bridge1 add hme2 ifconfig bridge1 add hme3 ifconfig bridge1 stp hme2 ifconfig bridge1 stp hme3 ifconfig bridge1 stp vlan40 ifconfig bridge1 spanpriority 61400 # avoid being the root bridge ifconfig bridge1 up is not working :( I want a solution, what is working with just one VLAN, so the VLAN is not dependent ont he phys interface. In your solution, if I don't pull up vlan41, than hme3 won't be in the bridge. This makes no sense. You don't add hme2 and vlan40(parent vlan2) to the same bridge. That's crazy talk, boy. The trunk interface handles redundancy across NICs if that is your end goal. You could use the failover or lacp options depending on the capability of your switch. Unfortunately I'm not sure that the vlan driver can easily layer on top of trunk, a few tweaks may be required to make it work properly unless it mirrors if_capabilities from the parent interface (which isn't clear to me after quickly paging through if_trunk.c). I'm not sure that you are solving the right problem by asking for redundancy across NICs. You are probably better served by asking for redundancy across boxes using CARP and PFSYNC and multiple firewalls
4.9-current (GENERIC) #47 kernel panic: Does not find any disk to boot from
Dear [misc] mailing list(eners), My amd64 system [4.8 (GENERIC.MP) #335] contains three sd? drives: sd0: MO drive sd1: boot disk sd2: additional disk In contrast to 4.8 (GENERIC.MP) #335 or 4.9 (GENERIC.MP) #819 kernels the snapshot 4.9-current (GENERIC) #47 kernel does not recognize sd1 as boot disk even when the MO drive sd0 is empty. The system ends up in ddb mode without having mounted any disk. Hence, there is no log file available after rebooting the old 4.8 (GENERIC.MP) #335 kernel. Included you find the boot messages for both 4.9-current (GENERIC) #47 (dmesg/ddb handwritten output), 4.8 (GENERIC.MP) #335 and, finally, 4.9 (GENERIC.MP) #819 (both dmesg log).

Re: Can command-line options be specified in any place?
OpenBSD specifically and old BSD in general is not true to Unix. From ksh to billions of options to find and other tools to the entire networking framework (bolted on with additional syscalls, pseudo devices etc), nothing of that is Unix (or even -like). Here is something to read: http://harmful.cat-v.org/cat-v/ Thanks for the link, it was a very interesting read. I have this dopey idea it would be fun to restore some of these programs on my system, mostly as a way to learn C, and also because I always get hung up on these little philosophical things rather than the real-world implications. There probably is no practical value to doing it other than the educational factor, but I don't really want to break my system in the process. That last part makes me wonder if there's a reason why OpenBSD devs didn't do this. I'm inclined to think it's because other things are more important to them in a world of finite time/manpower. If that's the reason, I may just plod ahead and give it a go, but if there's a functional reason, I'd like to know and would appreciate any insight.

ssh connections load on a server - NEWBIE question
What do you call an OpenBSD network admin? The answer is at the end of this message. What kind of server load will 62 sshfs connections have on an Atom server with 4GB RAM? The connections will last a workday. I am assuming that a sshfs connection is basically a ssh connection and hence the post on this list. Yes I did look through the archives w/o luck, and no I cannot easily create a test environment to measure what I want. If some soul has a similar experience, please share it. Mehma p.s. The answer is OB-WAN

That last part makes me wonder if there's a reason why OpenBSD devs didn't do this. What exactly? Removing useless options? On the one hand, that's often impossible because existing code, existing scripts depend on it. That's why adding useless knobs is so bad: You add them, people start using them, and if you wait too long, you can't rip them out any more. Sure, it would be nice to rip that unsigned abomination out of C. But who is goint to rewrite the world afterwards? On the other hand, we do remove things when we get a chance. Compare the number of tools and options in the groff-1.21p3 package and in mandoc(1), for example. I'm inclined to think it's because other things are more important to them in a world of finite time/manpower. No, you will find few other projects where people a so fond of removing useless stuff like round here. If that's the reason, I may just plod ahead and give it a go, but if there's a functional reason, I'd like to know and would appreciate any insight.

The answer is OB-WAN Doesn't sound like much load if it's just keeping the connections open. Depending on how much transfer, read/write, etc, you load may vary greatly. But keeping the connections alive should not be an issue. The amount of RAM may be an overkill for just this. Consider network speed, disk read (or write) speed, and other factor. In short, more info is needed to answer that question. If each connection is loading a 2kb file every hour, you'll have a different load than transferring HD video to all of them. -- Hugo Osvaldo Barrera
