Got it!

Answer: incorrect nc#

Sorry for the noise...

Hi, Alan, I also have one of these little systems from PCEngines. I've 
been following your thread. It's been a few years since I've messed around 
with my little 500Mhz AMD-based PCEngines board, but I think my method to 
solve the issue you are having was to hard set the console and baud rate 
in a custom kernel.



From the GENERIC conf file:

#optionsCONSDEVNAME="\"com\"",CONADDR=0x2f8,CONSPEED=57600

If you uncomment that line and nail the baud rate, then use that kernel 
you should be good to go.


This is uncomfortable but it works. What doesn't work however is the 
installation itself. The kernel boots for a while and stops on root 
device.


Can you do the install on another machine, install the custom kernel, then 
swap-a-roo the drive back to the PCengines host?


I can type what I want (wm0, wm1 etc.) but the installation hangs 
(sometimes after a curious message about NFS mount).


If you could post how far it got and what you see, that'd help.

Any ideas? Do you think that an network boot and install will solve 
these problems?


Why would netbooting help. I'm curious why that idea occurs to you? I 
thought the issue was the baud rate on the serial port ? I guess you could 
use a custom boot kernel via PXE/TFTP/BOOTP etc.. That might work/help.


I have tried to boot from an USB2 CDROM and booting the ISO image from 
syslinux system but this change nothing.


Are you passing any custom boot parameters? Can you summarize the specific 
issue you are having? I can try to help, since I have one of these 
machines myself and have used it for all kinds of BSD projects.

NetBSD 7.02 on APU2 PcEngines

[76nemo76]

Hi All,
  Finally I have switched between the speed of 9600bps and 115200bps
to install NetBSD 7.02 on APU2 from PCEngines.

This is uncomfortable but it works. What doesn't work however is the
installation itself. The kernel boots for a while
and stops on root device. 

I have to type the root device (and then the dump device) with a choice 
between: wm0, wm1, wm2 and wd0[a-p].
It's more or less as if the CD rom is no more found (by booting on
an other PC it seems that, at the moment of the boot process, 
the root device is "cd0a" and the dump device is "cd0b").

I can type what I want (wm0, wm1 etc.) but the installation hangs (sometimes 
after a curious
message about NFS mount).

Any ideas? Do you think that an network boot and install will solve
these problems?

I have tried to boot from an USB2 CDROM and booting the ISO image
from syslinux system but this change nothing.


kind regards,

Alan

serial console install at 115200 bps

[76nemo76]

Hi All,
  Almost all is alreay in subject. I plan to install NetBSD 7.02
on a PCEngines APU2 computer (https://www.pcengines.ch/). Basically,
this machine is an AMD64 PC without graphic card but with
a serial console working only at 115200bps.

The installation image (boot-com.iso) works at 9600bps. I would know
if it is possible to change the speed of the serial console
during boot (on openBSD it is possible to pass
a command "stty com0 115200" and in FreeBSD to add a parameter
in ISO image to boot with a serial console at 115200).

It is impossible to change the speed of serial console in BIOS
of PCEngines APU.

Without a solution, I think the only possibility is to start
at 115200, then disconnect from serial console and reconnect at 9600.

This is not very confortable but perhaps doable.

Thanks for ideas and help.

Best regards

Alan

Howto use agr to aggregate VPN tunnels

[BERTRAND Joël]

Hello,

	I open a new thread as I have made some tests and I'm now pretty sure 
that issue I see comes from NetBSD.


	I'm able to use agr with two physical ethernet controllers. But I'm not 
able to obtain a running agr interface with two OpenVPN tunnels.
Maybe problem comes from NetBSD kernel, maybe from misconfiguration, I 
have no idea to fix it.


	I have created two OpenVPN tap tunnels between a server an a NetBSD 
workstation (DEC PWS500au running 7.99.43, but I have seen same issue 
with 7.0.2 on amd64). Both tunnels runs as expected.


I have removed inet/inet6 address from both tunnels :

tap0: flags=0x8802 mtu 1500
ec_capabilities=5
ec_enabled=0
address: f2:0b:a4:b2:cb:28
media: Ethernet autoselect
tap1: flags=0x8802 mtu 1500
ec_capabilities=5
ec_enabled=0
address: f2:0b:a4:e9:16:fe
media: Ethernet autoselect

and I have created agr0 (round robin):

agr0: flags=0xb843 
mtu 1500

agrport: tap0, flags=0x3
agrport: tap1, flags=0x3
address: f2:0b:a4:b2:cb:28
inet 192.168.100.2/24 broadcast 192.168.100.255 flags 0x0
inet6 fe80::f00b:a4ff:feb2:cb28%agr0/64 flags 0x2 
scopeid 0x6


I have checked that 192.168.100.0/24 route goes through agr0 :
Internet:
DestinationGatewayFlagsRefs  UseMtu 
Interface

defaultweierstrassUG  --  -L epic0
127/8  localhost  UGR --  33112L lo0
localhost  lo0UHl --  33112L lo0

einstein   link#3 UHl --  -L lo0
192.168.100/24 link#6 U   --  -L agr0
192.168.100.2  link#6 UHl --  -L lo0

If I try to ping 192.168.100.1 (server), kernel sends packets to agr0 :

	I don't understand why there is no logical connection between tap0/tap1 
and agr0. Of course, I have verified that agr0 uses tap0 and tap1 as 
slave interfaces.


	The same configuration runs fine with two physical ethernet 
controllers. I have create agr1 that aggregates wm1 and wm2 (802.3ad):


agr1: flags=8843 mtu 1500
capabilities=7ff80
capabilities=7ff80
capabilities=7ff80
