Re: accidentally overwritten wrong drive with DD, please help

2024-06-26 Thread B. Atticus Grobe
This hasn't necessarily been explained very simply up to this point, so I'll give it a go. You are not going to be attempting to rebuild the filesystem or in any way make it functional. This is a key point to understand; the filesystem is done. Permanently broken. This is also the reason people k

A word of warning: even multiple overwrites are not guaranteed to erase any kind of flash-based storage. This applies even to some spinning rust now that have intermediate flash storage caches on them (although those tend to be enterprise-level devices). SSD/NVME's made by a reputable manufacturer

The E8400 processor doesn't support extended page tables, which vmm requires. AFAIK, all modern hypervisors require this.

I'm sorry the filter didn't work for you. I'm not using OpenBSD as a desktop right now, but I abused my router a bit to test, and can confirm that with an HL-L2370DW, the following printcap entry works, along with the filter. I know you've basically already moved on, but if you feel like giving it

Trouble with lpr and Brother wireless printer

2022-07-31 Thread B. Atticus Grobe
I use an HL-L2370DW which only accepts PCL on BINARY_P1. I think it likely that yours acts the same. You'll have to tell lp to send the output through a filter, using (iirc) the vf= option in printcap. This is what i used for a filter: #!/bin/sh gs -sPAPERSIZE=letter -sDEVICE=pxlmono -sOutputFile=

I've been running a Hewlett-Packard HP t620 Quad Core TC for a couple of years now in that role, with the AMD GX-415GA SOC in it. It's the bigger brother of that found in the APU systems. The stock configuration usually has 4GB of RAM in them, with a single re(4) 1GBps NIC, and a 16GB mSATA SSD.

Hardware for OpenBSD based access point

2022-03-13 Thread Atticus
AFAIK, OpenBSD doesn't support .11ac or .11ax at all, with only a very limited number of cards supporting Host AP mode. The only .11n ones I found being athn(4), bwfm(4), and ral(4). The (few) others that support Host AP mode only do so in .11g or .11b. In the future, I would take a look through se

SIP ALG and VoIP

2022-01-10 Thread Atticus
It isn't just SIP. You will need to set up NAT traversal and make sure RTP traffic can pass as well. Setting up a STUN server and configuring the clients to use it should aid in the NAT portion. The RTP traffic should be fine as long as pf is being stateful. If the phones register over SIP fine, bu

Add -R alias to -r for scp(1)

Second on adding an alias. I had no idea it was deprecated, and have never used -R at all... It never occurred to me to read the man page for cp. -- Byron Grobe On Thu, Jan 2, 2020, 11:57 AM Ingo Schwarze wrote: > Hi Marc, > > Marc Espie wrote on Thu, Jan 02, 2020 at 11:30:35AM +0100: > > > And
