On a Lenovo IdeaPad 3-15IGL05 81WQ[1] laptop:
$ time sh -c "printf '#include \\nint main() { puts(\"Hello,\
world!\"); }\\n' | cc -o hello -xc -"
0m01.24s real 0m00.16s user 0m00.42s system
15 seconds? What is happening in the background? Ports compilation while
encoding video?

Re: bgpd(8) not announcing IPv6 addresses from local network

My router is connected to two other routers via mgre0 to 2 other routers (routes should be sent to those 2 routers). The router which is sending routes has 4 NICs sit on a veb0 and are connected to some hosts on the network. These hosts are given prefix information by the router and autoconfigure their ipv6 addresses. > I'm not sure you must use BGP to advertise all your connected and static > routes.

I can see these hosts in the routers routing table, however bgpd doesn't advertise these routes, even though these routes are present within my routing table and I've specifically configured bgpd to advertise connected routes.

Rsync. I also have a root directory in /home to keep local stuff. This is the same for about 20 machines running obsd and is also distributed by rsync. Since it is in home, it survives upgrades. Various shell scripts in /home/root/etc are used to manage the system.

Hi,

Hello, all;
I've been having some issues getting bgpd to announce IPv6 routes,
apologies for the dumb question in advance.
I've setup rad(8) and bgpd(8) on an OpenBSD machine. bgpd(8) is
sending routes over to some neighbors (routes such as
fd80::fce1:baff:fea6:bf3a) while rad(8) is sending prefix information
for hosts to auto assign themselves some address (such as
2620:ba:6000:3:21db:f1bb:8ad9:21d6).
Is it possible to have a sample network diagram or at least a better
description of how you setup your network?
[...]
bgpd(8) is configued to advertise all connected and static routes,
however bgpd(8) only advertises routes that are connected to the wg0
interface and none that are connected on the vport0 interface.
I'm not sure you must use BGP to advertise all your connected and static
routes. Of course it depends on your setup and goals but ideally before
BGP you may use an IGP for any prefix related to your infrastructure.
Then use BGP for what you consider as your 'end-user' prefix.
But speaking of BGP at this point if you want to announce a prefix (not
just addresses), you must advertise it by BGP *and* it must be in your
routing table.
[...]
As far as I can tell bgpd(8) is configured correctly, and there are no
anomalies when it comes to routes. Below is a sample of my bgpd(8)
configuration for reference.
AS 10261
neighbor fe80::9ab7:85ff:fe00:3726%mgre0 {
remote-as 10261
}
neighbor fe80::9ab7:85ff:fe00:3727%mgre0 {
remote-as 10261
}
network inet6 priority 4
network inet6 connected
network inet6 static
Is it this router that is speaking with your upstream?
Here you expect bgp to advertise routes:
- with a priority somewhere else
- connected
- statically configured
Do you have them in the routing table?

On the upstream end it is just a web server with some files, including a file that has the sha256 hashes of the files. This happens to be updated by a git post-receive hook but you could do it however you want. In my .profile it checks the sha256 hashes of the local files against the remote files and if they differ, downloads them. I used $RANDOM to make sure this doesn't run every single time I start a shell. On OpenBSD this works using ksh(1), ftp(1), and sha256(1).

Compared to similar ThinkCenters I have (m73 Tiny and m92 Tiny). Also a Raspberry Pi 3 (running OpenBSD at lowest freq). It seems not to be the SSD disk because the "slowness" is present when writing to MFS mounts. > 14 Watts for compilation or just idling? Just at idle. Granted OpenBSD tends to run quite hot compared to alternatives it still seems to draw more than the m73 and m93p. > What issues?

I tested against different operating systems and different hardware. As mentioned there is definitely something up with this combo but I haven't had time to explore further. Hence my general note to avoid this machine if people can for now (if they want something guaranteed working). The C program can be as simple as compiling "Hello World" to exhibit the issue. Takes about 15 seconds to compile "Hello World". It doesn't need to be a "test" to suspect things aren't quite right here. > I suspect something different, I guess it is from the black / red > combination of the case colors. This is a broken combination and a > dangerous one in art and design. The m73 and m92 have similar case colors. So it is definitely not that ;)
