In such cases, the OS will not spend time doing software checksums, but the hardware will do it just before the packet leaves for the network, so that is why the software sniffer will see 0 there, but the remote end (you do look for errors from both ends, right?) will see something else there. -- May the most significant bit of your life be positive.

I've never used gnu fortran, but it might accept the -mcmodel=medium option like gcc and generate code sequences for data symbols that don't limit them to the bottom 2GB (or to within 2GB of the involved code, depending on gcc's choices in implementing the model). If it doesn't accept that option, then you'll need to work with the the docs, mailling lists, etc of the upstream gnu fortran project about how to have it generate code for the medium or large data models per the amd64 ABI.

Re: suggestions for USB printer (maybe even with scanner)?
A lot of people are mentioning the need to deal with the new lpr tools
being at /usr/local/bin.
I found that adding a symmlink from /usr/bin/lpr to /usr/local/bin/lpr,
etc. to help with programs that expect to find lpr at that exact
location.
Using a symlink will make life much easier with a few programs, since
everything finds what it needs at either location. You will need to
refresh the symlink after each upgrade. Backup the /usr/bin files just
in case you really do need them later.
Good luck! Printing is so damned easy or so brutally hard. ;-{)>

Re: suggestions for USB printer (maybe even with scanner)?
Hi Claus: USB printers are kind of difficult to set up on OpenBSD. You can read the instructions on USB setup in /usr/local/share/doc/pkg-readmes/cups. I never get USB printing to work on my OpenBSD 6.6. Instead I used a wireless Xerox Laser printer. Here is how I did it for a Xerox 6022 laser printer. I paid $150.00 USD for my Xerox 6022 Phasor To get this laser printer running over WiFi do: 0) Connect the Xerox Phaser 6022 to your wireless access point. I did this using a spare windows computer. I suppose you can do this through the little setup screen, on top of the laser printer. 1) Install the CUPS package. 2) Add the following line to your /etc/rc.conf.local file: pkg_scripts=cupsd. Reboot the computer to make sure CUPS is running. See man (8) rc.conf.local 3) From the CD that came with my Phaser 6022, I removed the file xerox-phaser-6022_1.0-22_all.deb. 4) This is an archive file. It contains your *.ppd. Do $ ar x xerox-phaser-6022_1.0-22_all.deb (See man (1) ar) 5) After extraction you will see data.tar.gz. That tarball contains the Xerox_Phaser_6022.ppd. Get the *.ppd with $ tar zxvf data.tar.gz 6) Move Xerox_Phaser_6022.ppd to /root. 7) Start a web browser and point it to "http://localhost:631";. 8) Select add a printer and login. I had to use my user account to login. Logging in as root would not work. You CUPS will probe your wireless network and you should see an address like 192.168.1.X, where X can be any number. It will also identify the printer as Xerox Phaser 6022. 9) Since there is no entry for Xerox, load the Xerox_Phaser_6022.ppd. 10) Complete the CUPS setup and you are ready to print You have to use the absolute path name /usr/local/bin/lpr, /usr/local/bin/lprm, /usr/local/bin/lpq and /usr/local/bin/lp to print with CUPS. LibreOffice prints with out modification. You can print photos and graphics (*jpeg, *.png , etc) with Firefox xpdf reguires the following line in the .xpdfrc: # Set the default PostScript file or command. psFile "|/usr/local/bin/lpr" # Set the default PostScript paper size -- this can be letter, legal, # A4, or A3. You can also specify a paper size as width and height # (in points).

YMMV. However, I've found Brother **LASER** printers to be very good, and most of them support PCL6 and/or PS3. For example, the HL-L2370DW can only connect via USB, and supports PCL6, and currently sells for ~C$150-160. Just don't try to use their MFC-* line of color printers under UNIX (except MacOS). FWIW, if you're in a situation where you have a spare Mac, the Mac can bridge from CUPS/PDF format to Brother proprietary format... bit pf a pain but it works. -Adam
Re: VLAN or aliases or? best way to isolate untrustable hosts in a small network
The OP’s hostname.vlan* files never specify a vnetid. I get an error trying to configure and bring up the second vlan interface the same way without vnetid specified. Regardless of my error, the ifconfig(8) man page says without vnetid specified, vlan tag 0 will be used. You need to specify two different vlan tags. All of that aside: VLANs don’t give you any more security. If the client host is on the same physical network as your two VLANs, the only thing stopping them from jumping between VLANs would be physical devices (switches, etc.) configured to prevent that. From what I gathered, you don’t have this level of control. Therefore, you gain nothing by segmenting the networks with VLANs. -Brian > On Feb 5, 2020, at 11:58 AM, Christian Weisgerber wrote: > > On 2020-02-05, Janne Johansson wrote: > >>> # /etc/hostname.vlan101 >>> description 'WLAN attached untrusted hosts' >>> inet 192.168.156.0/24 255.255.255.0 vlandev run0 >> VLANs and wifi sounds like a non-starter. > > Yep, if you're building your access point with OpenBSD. > > More generally, though, any AP in the business segment has support > for multiple SSIDs that can be assigned to different VLANs on the > Ethernet side. > > -- > Christian "naddy" Weisgerber na...@mips.inka.de

I have had good luck on OpenBSD with a variety of HP printers using the hplip package and cups. (To use the latter, put /usr/local/bin before /usr/bin in your PATH to avoid confusion with lpr programs.) The xsane package does scanning on HP printers that have this function. I have connected them mainly via the network, but I don't see why direct usb connections wouldn't work as well.

This is the error as you can review.
I cannot find solution in Internet and the real think is that in many
others post people copy and paste packets and this error is visible but no
one think that is in effect an error or do not speak about.
I try some value on sysctl but no results.

Yep, if you're building your access point with OpenBSD. More generally, though, any AP in the business segment has support for multiple SSIDs that can be assigned to different VLANs on the Ethernet side. -- Christian "naddy" Weisgerber na...@mips.inka.de

rtbuf 0.2.2
rtbuf is a minimalistic real time modular synthesis framework in pure C99. it supports OpenBSD sndio and now Linux too through Portaudio. to run ./rtbuf test_synth please contact me if you are interested in developing high quality real time applications under a BSD license. https://github.com/kmx-io/rtbuf -- Thomas de Grivel kmx.io
Re: VLAN or aliases or? best way to isolate untrustable hosts in a small network
Denis, I suspect the fundamental problem is that you don't understand what VLANs are. There should be a lot of articles about this topic on the net; maybe somebody here can recommend a good one. -- Christian "naddy" Weisgerber na...@mips.inka.de
Re: sndio programming question
Hi, I originally wrote this program around 5 years ago and didn't know it was in this bad state. So disregard debugging this for now, I'm fixing it up. I think I'm very close to getting it to work. For the size of the program, I wasn't thinking at the time, maybe I'll better post just an URL to the program next time. Best Regards, -peter
Re: VLAN or aliases or? best way to isolate untrustable hosts in a small network
Hi Christian, I've made two VLANs to automatically assign random IPs from a pool by dhcpd: # /etc/hostname.vlan100 description 'LAN attached untrusted hosts' inet 192.168.155.0/24 255.255.255.0 vlandev em0 # /etc/hostname.vlan101 description 'WLAN attached untrusted hosts' inet 192.168.156.0/24 255.255.255.0 vlandev run0 Going to filter access from these VLANs by PF. My 'real' LAN and WLAN _trusted_ devices get IPs from preregistered MACs in /etc/dchpd.conf. No free IP registration is available for _trusted_ devices. For _untrusted_ devices I'd like to set IPs by dhcpd from address pools vlan100 192.168.155.2 192.168.155.200, and vlan101 192.168.156.2 192.168.156.200 # echo 'dhcpd_flags="em0 run0 vlan100 vlan101' >> rcctl.conf.local # . rc.conf.local Added address ranges for vlan100 and vlan101 to /etc/dhcpd.conf and restarted daemon. DHCPd tries to assign address for _untrusted_ from real subnet with no free leases available instead from vlan100 or vlan101 pool provided. How do you set IPs for your trusted/untrusted devices using dhcpd? Could you share your dhcpd.conf setup for vlans you're using?

accessing fe80::%if inet6 in browser - small success
Hello, I recently managed to find an ISP that could provide IPv6 for my company, unfortunately this was a custom config = expensive and they have no implementation expernence = bad idea. Long story short they delivered a /56 on their router port (local ethernet segment), no way to firewall/route the traffic. If you are getting inet6 pay more attention than I did to how your connectivity will be delivered. If you need to firewall/route the traffic make sure you get an interconnection network global unicast or link-local in between their router and yours. A week after this I got a new network printer that does not need internet access and that should only be accessible on the local ethernet segment. Simple: I just use the printer's default link-local fe80:: address. Problems: Most software such as Firefox or CUPS do not accept the %if link-scope specifier. I tried to somehow deliver it using unbound, create a route without %if, try to manually insert the address without %if using ndp, url encode the %if, all failed. After about 3 hours I also tried the following: echo 'fe80::aced:bead:beef:code%em0 printer.local' >> /etc/hosts and now I can access the config page using printer.local using Firefox. Hope this is helpful, Dimitrios
sndio programming question
Hi, I have made a small program to read out MIDI commands for my Numark iDJLive II, DJ mixer (USB). I got rid of all my Apple software on Apple Hardware and there I had used Algoriddim DJ Pro software to take commands from this mixer. I pretty well made a crossfader and menu out of curses to make something like it and did some reverse engineering to get the controls for the MIDI output of the iDJLive II equipment. Granted not everyone has this hardware so I'm trying my best to explain what I'm doing by giving the source code of this. Basically the program works with 2 childs, where one child is the foreground and does the curses and input output to the mixer and the other child waits for commands passed to it via a shared memory (mmap). I can't manage to get it to make a sound when I select a song on the right play pad (#2), the worst I hear is just a small pop of the speakers and then silence so I'm doing something wrong. Let me explain the program lines and then I'll paste the program itself maybe someone who is experienced with music and sndio can help me a little? lines 263-282 - set up the mmap's for 100 MB each (this is both sides of the cross fader) 283 - is where it forks and the child continues on to waiting instructions to play what's in the mmap 299 - indicates where I'M having some problems feeding data to sio_setpar() the data stems from data gotten through getheader() which parses WAV files and placed at offset 2 on the mmap. The action at this point is really in the child and I don't know what I'm doing wrong so lines 283 through 340 which is in a continuous loop. Obviously the program isn't finished but I was hoping I'd pad out the rest when I'd get something playing on #2 at least. If you do have this equipment and start it, wiggle the crossfader a little for it to flash the leds for a while and then it will list any .WAV's to be selected with the "push" button, the "browse" buttons will select the songs of which only #2 is currently programmed to do anything. If I get this equipment working, I have another DJ mixer which is more portable that has different MIDI commands that I still need to sit down on and figure out. But I figured I'd make one work first before working on the other. Thanks for any hints regarding the playing of the WAV, the program follows, it gets built with: cc -g -o numark numark.c -lsndio -lcurses Regards, -peter 1 /* 2 * Copyright (c) 2020 Peter J.
