Re: Max Speed: configuration in smnpd.conf for display in mrtg
Thanks Stuart, I guess I had the right oid before, but the fact that is doesn't allow the replacement always give me a fail at restart, I assume I wasn't using the right oid. Oh well. Doing the max speed in mrtg is possible, sure ,but as I have to many routers that do change a lot as new customers are added or removed, it was a lot simpler to do it in the actual router then trying to always go back and over write the final configuration or mrtg each time.

Re: [OpenIKED] Network traffic over VPN site-to-site tunnel stalls few times a day

In my opinion upstream DNS & UDP issues can cause interrupts with some ISP's.
I also believe that defining specific proto's in your nat rule can decrease
interrupts.
You might consider the following to modification to your nat rule to
specificity allow UDP & ICMP.
match out log on $ext_if inet proto { tcp, udp, icmp } rom { $lan_rac_local,
$backup_local } nat-to $ext_if set prio (3, 7)
It appears that you have ICMP allow rules which is a good idea in my opinion.
Have you ever done any logging of these packets. Is there any legitimate
requests from your ISP?
Do you have an alternate DNS server you can test against? Are you using your
ISP’s DNS?
Perhaps the new OpenBSD unwind package is worth investigating ;)

I’ve found that fast networking is actually CPU & memory intensive.
Pentium 4 and Xeon's are increasingly a necessity for stable firewalls in
my opinion.
Keep in mind OpenBSD is a monolithic kernel & isn’t a one to one ratio
with a commercial router.
What are your context switches & interrupts doing while the VPN is up &
traffic is flowing?
vmstat -w 4
What is your memory high water mark during a peak traffic?
vmstat -m

Piping multiple lines of text via ssh
hello, i have set my own app as the shell of a user on a remote host. My app reads from stdin, and prints output to stdout. If I do: ssh u...@remotehost.com and manually type multiple lines of text,the app works as expected (i.e. it processess each line, and outputs the result) However, if I do this: ssh -T u...@remotehost.com < file.txt my tool only processes the first line, and then quits. any clues? thx, - m

From a security perspective it is better to run usbhidaction as an unprivileged user. rc allows this by setting the user parameter like this: $ doas rcctl set user I've updated my article to include this setting. By the way it also solves some trouble when you try to send commands to other media players like moc (https://moc.daper.net/) which check for security.

Re: How do I publish default router preferences using rad?
I want to enable a scenario similar to what's described in
https://tools.ietf.org/html/rfc4191#section-5.1
I run local network services for which I want a stable, publicly routed
prefix, but my ISP's delegated prefix isn't static. I've setup a
Hurricane Electric IPv6 tunnel to get a static prefix along side the
dynamic, ISP-delegated prefix; https://github.com/cqcallaw/openbsd-router
has details.
Everything is functionally correct with the source-based routing
configuration described in the docs, but the HE tunnel is necessarily
slow because of the overhead incurred by the 6in4 tunnel. Connections
are faster if my multihomed hosts prefer the native route for traffic
that doesn't require use of the tunnel.
I had patched rad to experiment with route preferences as a solution to
this performance issue, but my local hosts don't seem to honor the
advertised route preferences. I'm still researching what's required on
the client side for route preferences to be honored.

pppoe only connects if tcpdump is running?!
Hello! I got myself a new PCI ethernet card instead of an old USB3 to ethernet in a "router" named desktop machine. in short: But pppoe doesn't connects via the new PCI card. Only if I start a tcpdump on it!? longer: # # THE CONFIG router# cat /etc/hostname.re1 up lladdr xx:xx:xx:xx:xx:xx router# router# cat /etc/hostname.pppoe0 inet 0.0.0.0 255.255.255.255 NONE pppoedev re1 authproto pap debug authname 'censored' authkey 'censored' up dest 0.0.0.1 !/sbin/route add default -ifp pppoe0 0.0.0.1 router# OpenBSD 6.5 amd64 # # THE STATE router# ifconfig re1 re1: flags=8843 mtu 1500 lladdr xx:xx:xx:xx:xx:xx index 2 priority 0 llprio 3 media: Ethernet 100baseTX full-duplex status: active router# router# ifconfig pppoe0 pppoe0: flags=8855 mtu 1492 index 5 priority 0 llprio 3 dev: re1 state: PADI sent sid: 0x0 PADI retries: 5 PADR retries: 0 sppp: phase establish authproto pap authname "censored" groups: pppoe egress status: no carrier inet 0.0.0.0 --> 0.0.0.1 netmask 0x router# router# dmesg|grep re1 re1 at pci3 dev 0 function 0 "Realtek 8168" rev 0x07: RTL8168E/8111E-VL (0x2c80), msi, address xx:xx:xx:xx:xx:xx rgephy1 at re1 phy 7: RTL8169S/8110S/8211 PHY, rev. 5 router# # # I TRIED: - rebooting, waiting for many minutes - pap or chap - mac filtering is OK, that is the MAC, what is in the hostname.re1 - doing: ifconfig re1 media "10baseT" - thinking of cable issue - tried to plug in to the pci eth card via a Gbit switch, still no pppoe - "ifconfig pppoe0 down" and "up" gives only these debug messages: down: Aug 24 15:15:06 router /bsd: pppoe0: lcp close(starting) Aug 24 15:15:06 router /bsd: pppoe0: lcp starting->initial Aug 24 15:15:06 router /bsd: pppoe0: phase dead up: Aug 24 15:15:11 router /bsd: pppoe0: lcp close(initial) Aug 24 15:15:11 router /bsd: pppoe0: lcp open(initial) Aug 24 15:15:11 router /bsd: pppoe0: lcp initial->starting Aug 24 15:15:11 router /bsd: pppoe0: phase establish Aug 24 15:15:11 router /bsd: pppoe0 (8863) state=1, session=0x0 output -> ff:ff:ff:ff:ff:ff, len=18 # # INTERESTING THING: if I plug back my old USB3 to ethernet, it works instantly (via the usb3 eth): router# mv /etc/hostname.re1 /etc/hostname.cdce0 router# sed -i 's/re1/cdce0/g' /etc/hostname.pppoe0 +puting the ISP cable to cdce0. then "reboot" it works... gets IP: router# ifconfig cdce0 cdce0: flags=8843 mtu 1500 lladdr xx:xx:xx:xx:xx:xx index 5 priority 0 llprio 3 router# router# ifconfig pppoe0 pppoe0: flags=8855 mtu 1492 index 6 priority 0 llprio 3 dev: cdce0 state: session sid: 0x5eb PADI retries: 0 PADR retries: 0 time: 00:00:20 sppp: phase network authproto pap authname "censored" groups: pppoe egress status: active inet yy.yy.yyy.yyy --> 10.0.0.1 netmask 0x router# # a funny thing happened.

Why? I can 100% reproduce it. If I stop the tcpdump, the public IP stays, but there is no internet connection to the world. is this a bug? or a flag is set by tcpdump for the nic? # What am I missing? Why can't I connect via pppoe with the PCI ethernet card without running tcpdump on it? Thanks.

Thanks. Hm, now the same command does play, and there is yeast on my monitor. Thanks. mplayer auto-recognizes the mjpeg format, but reports a lot of frame-decoding errors (see below).
