FuguIta 7.1: IceWMで日本語が表示されない†

kaw (2022-05-08 (Sun) 23:53:30)

#FuguIta 7.1を使い出して気がついたのですが、IceWMを使うとウィンドウタイトルやメニューなどで日本語の文字列が表示されません。
これは、IceWMのデフォルトのフォント設定が変更されたためのようです。
解決方法としては、フォント設定の"DejaVu"、あるいは"dejavu"となっている部分を削除すると日本語部分が表示されるようになります。
具体的には以下のコマンドを実行することで解決されます。

$ grep -i -B1 'dejavu' /usr/local/share/icewm/preferences | \
sed 's/^--$//; s/^# *\(.*\)[Dd]eja[Vv]u *\(.*\)/\1\2/' > ~/.icewm/preferences

"expand" vs. "encrypted partition"†

liar666 (2022-05-04 (Wed) 17:02:59)

#FuguIta
Hi,
Thanks for the great tool, with so much options. I love it!
I've dd'ed the (2.1GB) img on a 4GB USB stick, now I would like to configure an encrypted space to store my data/pkg.
I read pages about "expand" (StartGuide) and "encrypted partition" (BB/9), but I'm not sure if:

• they are exclusive and I should do *either* one *or* the other, or
  
• I should expand first, then setup an encrypted partition
  

  #FuguIta
  

• PS: In the "Notice" at the top of the page ("To avoid posts by spam, a message body without the word '#FuguIta' is rejected.") you should add that adding URLs (even to this exact website) to the message also makes it tagged as spam -- liar666 2022-05-04 (Wed) 17:07:00
• Thank you for liking #FuguIta.
  usbfadm's expand subcommand is for fitting the distributed FuguIta LiveUSB image to your USB flash drive.
  Unfortunately, it is not a universal tool.
  The easiest and surest way to fulfill your request is to run the usbfadm utility on your FuguIta LiveDVD or FuguIta LiveUSB and apply newdrive subcommand with encryption option to your own another USB stick. -- kaw 2022-05-06 (Fri) 11:08:29

How to use new build tool of FuguIta†

kaw (2022-05-02 (Mon) 00:01:06)

FuguIta 7.1 has made significant changes in the way the build tool is used. Much simplified compared to the previous method, A live ISO image can be created by deploying the build tool, placing the set of file, and running make.

In following explanation, FIBLD represents the working directory for building FuguIta.
Please replace it with your actual working directory when building.

1. The build environment is OpenBSD 7.1 or later, or FuguIta 7.1 or later, with root privileges.
2. Put OpenBSD kernel source code under /usr/src/sys.

   # tar -xz -C /usr/src -f sys.tar.gz

3. Extract new FuguIta build tool under FIBLD.

   # mkdir FIBLD
   # cd FIBLD
   # tar -xz -f tools-7.1-amd64.tar.gz && mv tools-7.1-amd64/* .; rmdir tools-7.1-amd64

   For the other platform, replace "amd64" with its name.
   
   
4. Copy or symlink OpenBSD install sets (e.g. *71.tgz) under FIBLD/install_sets.

   # cp SOMEWHERE/*71.tgz FIBLD/install_sets/.

   or

   # ln -sf SOMEWHERE/*71.tgz FIBLD/install_sets/.

5. Copy or symlink rsync, rlwrap, pv package files in FIBLD/install_pkgs.

   # cp SOMEWHERE/{rsync,rlwrap,pv}-*.tgz FIBLD/install_pkgs/.

   or

   # ln -sf SOMEWHERE/{rsync,rlwrap,pv}-*.tgz FIBLD/install_pkgs/.

6. Compile the kernels for FuguIta. In FIBLD, do the following:

   # make kernconfig && make kern

7. Extract the OpenBSD file tree and modify it for FuguIta.

   # make stage

   If you want to customize FuguIta, modify the file tree under the directory staging after this.
   
   
8. Make the contents of image file identical to this file tree

   # make sync

9. Combine the kernels, boot loaders, and an image file to create a versioned ISO file.

   # make iso

10. Compress the ISO file with a filename containing the release string

    # make gz

MSDOS FAT : 3GB†

m3th (2022-04-30 (Sat) 04:52:08)

Is it possible to install Fuguita 7.1 over an already existing Fuguita 7.0 without losing my data on fat partition? When are you going to end support for Fuguita 7.0? Should I upgrade it asap?

#FuguIta

• If you install #FuguIta 7.1 on a USB flash drive with FuguIta 7.0 already installed, all existing data including FAT partition will be lost because the partition information will be overwritten.
  Therefore, please backup the data on the FAT partition in advance and copy it from the backup to the new partition after installing FuguIta 7.1.
  After FuguIta 7.1 is released, Errata will no longer be applied to FuguIta 7.0, but the final release of FuguIta 7.0 will be kept in the mirror's /old directory. So, please migrate from 7.0 to 7.1 at your convenience. -- kaw 2022-04-30 (Sat) 09:19:57
• I'm about asking just the same. so, If we can't simply upgrade from 7.0 to 7.1 and also upcoming releases, our next question is How do we backup our #FuguIta config and files easily and conveniently? Thank you -- [[Arfian ]] 2022-05-04 (Wed) 13:40:34
• As you say, there is no migration tool provided from #FuguIta 7.0 to 7.1.
  I would suggest that you back up your data on FuguIta 7.0 to another media or another host. Then create a new FuguIta 7.1 and copy /etc, /home from your backed up data to it. For /etc, you can use sysmerge after copying to follow the release. For packages, it is better to save the output of "pkg_info -tz" on 7.0 then run pkg_add on 7.1 accordingly. -- kaw 2022-05-07 (Sat) 07:34:00

Change on FuguIta 7.1†

kaw (2022-04-26 (Tue) 01:02:40)

I'm working on FuguIta 7.1 with plans to release it soon.

#FuguIta 7.1 changes from TMPFS to MFS as a memory-based file system. Please see the ML archive for the details of the change.

This will result in the following changes

• The automatic specification of file capacity that existed in TMPFS does not exist in MFS. You will have to specify it explicitly.
• The maximum amount of files that can be held in memory will be a little over 1GB on the i386 platform and a little over 30GB on amd64. This is a limit of MFS itself, and the value is independent of the page-out to the swap partition.

How to port PFFW to FuguIta†

kaw (2022-03-04 (Fri) 18:27:07)

PFFW is a firewall management software running on OpenBSD that continues to be developed by Soner Tari.
PFFW uses OpenBSD's packet filter PF and provides a web user interface for configuring PF and monitoring PF and OS behavior.

I have ported this PFFW to FuguIta LiveUSB and would like to introduce the procedure.

Overview
PFFW is available as an ISO image for installation, including OpenBSD itself and related packages, and porting to FuguIta LiveUSB is generally done as follows

• Install PFFW in the usual way.
• After installation, take out the PFFW-specific parts.
• Run FuguIta LiveUSB and extract the files from PFFW onto FuguIta.
• Modify some files so that PFFW and FuguIta work together.
• Save the modified contents to FuguIta LiveUSB.

Install PFFW in the usual way.
Refer to the PFFW GitHub Page and download the installation image.
Refer to the How to Install section of the PFFW GitHub Page for instructions on how to install from the downloaded image.
Installation can be done either on the actual device or on a VM, but it is easier to do it on the actual device because of the network interface settings.

During the initial setup of PFFW, answer no to the question if you want to use MFS.

If the system has enough memory, you can mount /var/log as MFS
Enable MFS? [yes] no

MFS /var/log disabled.

FuguIta uses TMPFS, so the same effect can be achieved without MFS.

After installation, take out the PFFW-specific parts.
Next, launch the installed PFFW and archive the PFFW-specific portions.

pffw# cd /
pffw# tar czf /root/pffw.tar.gz etc usr/local var

Please copy this pffw.tar.gz to another media, another host, etc. so that it can be read from the FuguIta environment you will create later.

Run FuguIta LiveUSB and extract the files extracted from PFFW onto FuguIta.
Run FuguIta LiveUSB, which is the destination of PFFW, in mode 0.

Boot modes:
   0: fresh boot - standard mode as a live system
   1: fresh boot - less memory, faster boot
                  (/usr is non-writable, can't pkg_add)
   2: fresh boot - works using only RAM
                  (about 1GB or more of RAM required)
   3: boot with retrieving saved files from storage device
      or enter passphrase for an encrypted volume
   4: boot with retrieving saved files from floppy disk
   5: interactive shell for maintenance
-> 0

After booting is complete, extract the files you have just archived.

pffw-fuguita# cd /ram
pffw-fuguita# tar xvzpf pffw.tar.gz

Modify /etc/rc.

pffw-fuguita# cd /etc
pffw-fuguita# patch < /boottmp/etc.rc.diff
Hmm...  Looks like a unified diff to me...

permit nopass user as root cmd /ram/var/www/htdocs/pffw/Controller/ctlr.php
permit nopass keepenv root as root

In FuguIta, /var is a symbolic link to /ram/var, and doas will not allow execution with the original contents.
/var must be changed to /ram/var, which is a realpath.

Merge /etc/rc.shutdown for PFFW and FuguIta.

pffw-fuguita# cd /etc
pffw-fuguita# mv rc.shutdown rc.shutdown.pffw
pffw-fuguita# cat rc.shutdown.pffw /fuguita/etc/rc.shutdown > rc.shutdown

Uncomment the last line of the merged rc.shutdown.

          sleep $waitsec
      done )
}

# To re-sync on shutdown. uncomment the following line.
usbfadm_r    <== Uncomment this line.

This will cause the file to be saved to the USB flash drive and then shut down after the PFFW exit process is complete.

Save the modifications to the FuguIta LiveUSB.

To automatically specify the device name and save name and start up, please refer to the FuguIta's Start Guide.

• The PFFW installer is designed to install OpenBSD itself and related packages together, so a computer with PFFW installed becomes a "firewall-only machine" (which is usually fine as a mode of operation). By porting PFFW to #FuguIta, the PFFW environment can be loaded and operated only when necessary. It is also easy to migrate and operate on other hardware. -- kaw 2022-03-05 (Sat) 00:33:56
