Driver support for Marvell Amethyst (on MikroTik RB5009UG+S+IN)

[Alex Waite]

Hello Everyone,

I will purchase a new home router soon, and hope to consolidate my ancient 
switch into it as well.

Has anyone here had success running OpenBSD on the MikroTik RB5009UG+S+IN? [1]

It's ARM8 64-bit, so I expect OpenBSD to install and run, but the networking I 
am unsure about (Marvell Amethyst 88E6393X). [2]

I have not found any information about OpenBSD support for the Marvell Amethyst 
series, so I fear that it is not (yet) supported. Can anyone confirm one way or 
the other, or speak to the likelihood that support will be added?

How do you manage file sharing between these systems (if it all)?


Not sure what your environment is, but I'm a big fan of sshfs for light 
usage.


Then you can view Samba as a service for compatibility with the island 
that is windows.


* linux box hosts the data and shares via samba
* Win boxes connect via Samba
* All other *nix system connect using sshfs

If you get motivated, there's probably some "mount this sftp server as a 
drive" software for windows, and then you can get rid of Samba. But I've 
never looked for such a thing.

We're in the process of preparing for upcoming conferences with updates
to the ever-in-progress PF tutorial.

If you have thoughts on what you would like to see in a tutorial session
and would like to share them either with me or the list, we would love
to hear from you.

I would like to see more indepth discussion of queues, anchors, and
authpf. I suspect either of the three could probably fill an entire pf
tutorial.


I second this in its entirety.

Re: Suggestions home server

[Alex Waite]

I am considering buying a not so expensive home server.
[snip]
This might be a bit above "not so expensive" (~1,200), but I've been 
running this at home for just under a year and have been very pleased:

Caveat: I'm running SmartOS on the metal and OpenBSD (and other OSs) in 
zones/KVM.

Re: logging in to joyent images

[Alex Waite]

Hey Lyndon,


I have installed one of the openbsd-6 SmartOS VM images, gotten the
VM to boot, but I'll be damned if I can find out anywhere a login id
and password that will actually let me log in to the bloody thing.
Anybody been down this road and have an answer?


I have only limited experience with SmartOS, but the quick fix is to 
login to the global zone and use zlogin to enter the VM (get the VM hash 
from vmadmin list). You'll then have a shell and can change the 
password, add users, and adjust the sshd config to your liking.


Another option is, when writing the JSON descriptor, to have it inject 
an SSH key into the machine when provisioning. I've never done this 
myself, but I know there's a few examples floating around on the web 
somewhere.

Some nice useful info in there. Especially the USB driver. Thanks for

Check out the Ubiquiti Edgerouter Lite.  Sub $100 (US), three NICs,

I've used it as a router, firewall, dhcp server, you name it.  Versatile device.


Nice idea. Thanks. :-)

Do you mean it runs OpenBSD by default, or you can install OpenBSD?


Just that it can run OpenBSD. No need for default.

Cheap 2x NIC OpenBSD device

[Alex Waite]

I'm deploying a server to a different data center and I don't want to 
expose the IPMI interface of the machine to their semi-trusted 
management network. So, I'm planning on putting a simple OpenBSD device 
in front of it, logging and filtering.


Can someone here recommend a relatively cheap (< ~100 EUR) device that 
runs OpenBSD and has 2 NICs?

allow/deny BOOTP in dhdcpd.conf

[Alex Waite]

Hello Everyone,

I am pretty new to the networking world. But as a sysadmin, I am 
thoroughly appreciating pf and OpenBSD as a whole. I think I may have 
fallen in love.


My question is about BOOTP. I've always heard it in the context of PXE 
booting, but as I was configuring it in dhcpd.conf, I got that weird 
tickling sensation that made me think there might be more to it. And 
indeed the Wikipedia article[1] indicates that it at least /was/ used 
for more and is largely, though not entirely, superseded-by/merged-into 
DHCP.


I've read the man page for dhcpd.conf, and it seems to strongly 
imply/assume that one would only use BOOTP support for PXE, but it isn't 
entirely explicit on that point.


So my question is: will "allow/deny bootp;" in dhcpd.conf enable/disable 
anything other than PXE support?


Thank you for your time.
