incorrect link for OpenBSD 6.9 patches†

Mel (2021-05-11 (Tue) 14:26:19)

in front page of #FuguIta there is "Patch 001 of OpenBSD 6.9 has been applied."

when you click on the link, it goes to OpenBSD 6.8 list of patches.

Video Streaming by FuguIta†

kaw (2021-05-01 (Sat) 08:06:34)

In Niigata Prefecture, where I live, there is a traditional event called "Ushi no Tsuno Tsuki" ("Poke of bull horns" - bullfighting).

The first event of the year was held on April 29th, and I participated as a member of the team that delivered the video.

I was in charge of delivering the video directly to the smartphones and tablets of the audience at the event.

In this event, the MC and the remote guest interact via ZOOM, and the purpose of my job was to show the audience what was going on.

This was my first attempt at this, and the followings are required.

• low latency
• video only, no audio (to be heard over the PA)
• no need to install any application, just a browser.

To achieve this, I made the following choices

• Free WiFi turned out to be difficult to use for this purpose.
  • Establish a local network and operate inside it.
  • Install a WiFi access point.

• Adopt WebRTC technology.
  • TLS is required for WebRTC

Based on the above conditions, you will need the following

• dhcpd
• TLS httpd with certified domain
• local DNS

All of the above features are available in OpenBSD from the start, except for the web browser and WebRTC. So I decided to use #FuguIta as a base for implementing these.

For the video distribution software, We used Screego. Conveniently, Screego is supplied as an executable binary for OpenBSD.

Furthermore, this network is not completely independent and needs to remain in communication with the Internet. This is because smartphones communicate with sites on the Internet to determine the status of the network. If there is no communication with the Internet, the smartphone will complain. In addition, time synchronization is required for TLS communication, and therefore, NTP must be available. For these purposes, I decided to create a NAT in PF. I decided to limit the bandwidth of the communication through the NAT, because the main purpose of this Internet access line is to upload the video of the event to YouTube, and to communicate with the remote performers via ZOOM.

Based on the above, I decided to configure and operate the network as follows.

As for the web browser for the video distribution, We had originally planned to use Windows, but since the title bar of the window was displayed on the video to be distributed, and the video input with an aspect ratio of 16:9 was somehow changed to 4:3, I decided to use FuguIta for this purpose as well, and use MPlayer to convert the aspect ratio of the video to 16:9 and send it by Chromium.

The operation of the day is as follows.

As a result, it worked as planned, but there were a few problems.

• Screego terminated abnormally once and delivery was temporarily interrupted.
• WiFi access point saturation
• Traffic exceeding the set bandwidth of the Internet uplink (misconfiguration of pf.conf?)

We will need to improve on these issues in the future.

This time, I planted a monitor script modified from SAG in both the Screego server and the browser for sending images, so We will analyze the logs and plan countermeasures.

• Thanks for sharing a use case for #FuguIta. I use #FuguIta now as security system. I use motion(1) from ports, and capture RTSP data from 2 cheap IP camera. motion(1) detect motion and starts recording. Now it is very simple, it does not send any email notification to me. -- Mel 2021-05-02 (Sun) 07:41:15
• This is the first time I have heard about motion(1). Thank you for telling me about it.

FuguIta development†

Mel (2021-04-27 (Tue) 15:35:18)

i try to follow how to setup development for #FuguIta from this JPN page "河豚板の開発ツールを使う - LiveDVDのカスタマイズと作成".

i download the construction tool tools-6.8-amd64.tar.gz. there is .ffsimg file (media/fuguita-6.8-amd64.ffsimg).

i understand this is for OpenBSD 6.8, if i want 6.9 this ffsimg should be updated. but, my question is, how do you create this .ffsimg file for each new release of OpenBSD?

• When 6.9 will be released, I'll download *69.tgz files and then extract all of them.
  Next, I'll some modifications to adapt this to FuguIta. They are:
  
  • extract /var/sysmerge/*etc.tgz
  • fix dangling symlinks in /usr/{bin,sbin}
  • remove /usr/share/relink/kernel.tgz (KARL makes no sense for Live System)
  • prepare files under /usr/fuguita
  • add /usr/fuguita/{bin,sbin} to $PATH
  • sh ./MAKEDEV std (in a chrooted environment)
  • pkg_add rsync, rlwrapper and pv, then ldconfig (in a chrooted environment)
  • modify /etc/hosts, /etc/mtree/special and /etc/sysctl.conf
  • add /etc/localtime, /etc/firsttime, /etc/installurl, /etc/man.conf, /var/db/host.random, /root/.Xauthority and /etc/skel/.Xauthority
  • prepare /etc/rc.diff which will be applied at boot time
  • prepare /usr/fuguita/etc/mode0symlinks.cpio.gz with /usr/fuguita/sbin/gen_mode0sldir utility (This is for fast boot. FuguIta works without this file)

Above is the standard procedure to setup the content of *.ffsimg, and may have any variations by every OpenBSD release.
And also, it may possibly vary anymore at your case.

-- kaw 2021-04-28 (Wed) 05:40:16

syspatch†

m3th (2021-04-24 (Sat) 18:32:09)

Can I syspatch to #FuguIta?

• Because FuguIta is different from regular OpenBSD in many ways, syspatch cannot be used with FuguIta.
  
  For example, the FuguIta kernel was built to run the Live System, so it is not possible to use syspatches that are intended for use with the GENERIC kernel.
  
  Another reason why syspatch cannot be used is that the filesystem configuration is also very different from that of regular OpenBSD.
  
  FuguIta provides the fiupdate utility to update the system, so please use it if you are using LiveUSB.
  
  For more information on updating FuguIta, please refer to the following article.

Prototype from snapshot†

kaw (2021-03-23 (Tue) 18:01:06)

Prototyped a trial version of #FuguIta based on OpenBSD-current (6.9-beta).
It is only available for the amd64 architecture.
Get it from "test" directory on download mirrors.
Your trial reports are welcome.

• i tried it in vmd, it works. i have Panasonic CF-J10 running 6.8 #FuguIta but i probably will not test it on that machine. the problem is since 6.9-beta is a -current i can't install packages. i try to install "motion" and some dependency is not correct. -- Mel 2021-04-27 (Tue) 15:25:04

Change of mirror servers†

kaw (2021-02-16 (Tue) 19:00:58)

Two new mirror servers in Europe are now in operation.

They are de.dl.fuguita.org and fr.dl.fuguita.org, the successors to eu.dl.fuguita.org.

eu.dl.fuguita.org will be out of service in a few weeks.

I would like to express our sincere gratitude to the administrators of eu.dl.fuguita.org and everyone who are providing the mirror servers.

Laptop Connected to Monitor†

(2021-01-30 (Sat) 07:41:07)

I can use a second monitor with OpenBSD. I cannot use a second monitor with #FuguIta.

r600_cp: Failed to load firmware "radeon/SUMO2_pfp.bin"
[drm] *ERROR* Failed to load firmware!
drm:pid0:radeondrm_attachhook *ERROR* Fatal error during GPU init
drm0 detached
radeondrm0 detached

I saved settings after downloading the firmware, rebooted, and do have "/radeon/SUMO2_pfp.bin". I assume this error happens because the boot process executes the GPU init before I can choose boot mode 3. Is there an easy way to fix this error, myself?

Sorry. I am inexperienced with BSD (and computers).

• As you would expect, this is because #FuguIta's kernel tries to load the firmware before mounting filesystem which holds file of the firmware.
  To solve this problem, FuguIta's kernel must have the firmware in the root filesystem which is built in the kernel.
  
  In case of LiveDVD, you must rebuild ISO image to have the firmware built-in.
  This is quite complexed process, so you may select to use FuguIta LiveUSB or vanilla OpenBSD.
  
  If you use LiveUSB, you can write the firmware to built-in root filesystem with following process:

  # gzip -dc /sysmedia/bsd-fi.mp > bsd-fi.mp
  # vnconfig vnd0 bsd-fi.mp
  # mount /dev/vnd0a /mnt
  # mkdir -p /mnt/etc/firmware
  # (copy radeon's firmwares under /mnt/etc/firmware)
  # umount /mnt
  # vnconfig -u vnd0
  # mount -uw /sysmedia
  # gzip -c9 bsd-fi.mp > /sysmedia/bsd-fi.mp
  # mount -ur /sysmedia

Ventoy Compatibility?†

Fugu (2020-10-24 (Sat) 22:05:09)

Hello kaw:

Any chance of getting #FuguIta working with ventoy at www.ventoy.net/en/index.html.

No pressure - just asking since Fugu's broader goals align with such a tool.

Thank you.

• I've never heard of Ventoy. This seems a quite interesting tool.
  Looking at Ventoy's support list, it seems that the operation of #FuguIta has failed.
  In the first place, it seems that BSD-based OS such as OpenBSD itself is not supported very well.

• Hello Kaw: \n I just tried the cd and miniroot iso and img files of OpenBSD and could get to boot screens without issue. #FuguIta profile load looks for a hard drive and cannot proceed further. Is moving that part to ramdisk possible? I was thinking of antiX user settings load to RAM setup. -- Fugu 2020-10-25 (Sun) 15:49:03
• FuguIta tries to mount all partitions of all disk devices in order at boot time.
  This is to find the partition where the FuguIta system is stored and the partition for data storage.
  FuguIta booted from Ventoy is booted from a virtual disk, so it is unlikely that you will be able to find the device that contains the FuguIta system.
  You may be able to boot in fresh boot mode (modes 0, 1 or 2) by placing the ISO image on physical FAT / NTFS or ExtFS, as described in the chapter Coexisting FuguIta with Windows or Linux of the FuguIta Guide. -- kaw 2020-10-26 (Mon) 10:49:35

Is there a difference in boot mode of OpenBSD and #FuguIta? I have a Dell PC where OpenBSD is very slow without disabling acpimadt whereas #FuguIta has no such problems.

Any guidance will be gratefully received.

Thank you.

  So I don't know why it behaves differently.
  
  Since the storage device used is different between regular OpenBSD(internal HDD, SSD...) and FuguIta(DVD, USB Flashdrive, SD card...) there may be something wrong with the built-in disk device.
  
  In any case, I think we need to see what's slowing down regular OpenBSD.
  • disk I/O
  • stray interrupts
  • anything else?

• Thank you for the detailed response. It has to do with buggy bios - APIC. Thank you for sharing #FuguIta with us. -- Fugu? 2020-07-21 (Tue) 09:49:27
• With following procedure, you can check whether the internal disk or its corresponding BIOS function causes the problem:
  
  • In internal disk, make a directory named "ISO" at the root of a partition which is FAT, NTFS, Linux ExtFS or OpenBSD FFS.
  • Put a FuguIta's ungziped ISO image into "ISO" directory.
  • Boot FuguIta with LiveDVD or LiveUSB.
  • The internal disk will be listed as follows:

    scanning partitions: cd0a sd0i sd0j
    FuguIta's operating device(s): cd0a sd0i
    Which is FuguIta's operating device? [default: cd0a] -> sd0i  # in case that sd0 is internal disk

  • Select internal device, then continue booting.

If FuguIta runs slow as OpenBSD with this procedure, the problem could lay on internal disk device. -- kaw 2020-07-21 (Tue) 16:28:11

• I had quite a few ideas to test this:
  
  • Chroot install
  • chain load from a different OS
  • install via different system and move hard drive
  • use a different boot manager
  • install #Fuguita and hack via ramdisk

and one other escaping attention now.
To this end, I started reading through the show and list variables in the UKC config and found that #FuguIta has a lot more that get initialized than vanilla OpenBSD. When that did not work out, I once again disabled acpimadt, installed the operating system and waited for it to boot. The scenario now stood at reordering libraries (library_aslr). I let it complete the first time and then disabled the service via rcctl. This made a dramatic impact on reboot.
Presently, after having run sysupgrade (following -current), the performance is acceptable as good as on a ThinkPad.
My speculation is to do with the execute bit. I haven't read the source code to be certain of this but would appreciate your knowledgeable thoughts on it. I will try the above solution if video and browser performance in unacceptable with my continued testing. -- Fugu 2020-07-21 (Tue) 19:37:36

• Summary Update: During upgrade/install, the acpimadt needs to be disabled during runtime only. All things work except for the cpu temperature which is stuck at a very high inordinate value. The only similarity found is when the install medium is flash disk. Fans, hibernate, sleep - power management; userland setup; networking have no problems. Interestingly, #FuguIta also spends some time in kernel reordering but being a ram-mounted filesystem, the time spent is comparatively smaller. This is a two-hard drive machine and OpenBSD live USB is now getting stuck before Install/Upgrade/Interrupt message prompt (custom part of #FuguIta) - seems to be directly correlational to number of partitions. Pressing power option still gives back the prompt. Although the device will not be high workload intensive, lack of temperature monitoring (#FuguIta live also lists the same numbers) is unnerving. -- Fugu 2020-07-22 (Wed) 14:55:26
• Thank you for the detailed information.
  Is vanilla OpenBSD slowing down because the CPU temperature is considered high and the CPU clock frequency is low?
  If let apmd enabled and manually change the CPU clock with the apm command, can you see anything relevant? -- kaw 2020-07-23 (Thu) 12:54:58
• Hello Kaw: What I meant to say is everything works as in a supported machine except the sensor for reading the cpu temperature is broken.
  My guess is that this failure to initialize during boot is what causes the problem. #FuguIta does not display this behavior since the boot process has custom setup at this exact point where OpenBSD seemingly hangs. Just before shell access, there is an info which says XSDT entry 8 is corrupt. Not sure if OpenBSD devs would want this bug report since this is BIOS initiated.
  When I say userland setup, the fans (two of them) scale according to workload. I stress tested by encoding a video and simultaneously running a 4K Blender video. Everything works once the module is disabled during install/upgrade (workaround with sysupgrade -n) - one time activity only.
  I genuinely look forward to seeing you presenting #FuguIta this weekend. The only time I had these issues was with booting lilo on Slackware though FreeBSD works without complaint.
  Best wishes. -- Fugu 2020-07-23 (Thu) 23:05:59
