[gentoo-user] Purpose of bashcomp_alias in bash-completion-r1.eclass?
Good day! Before reporting a bug I wanted to hear other opinions on that: In bash-completion-r1.eclass, what is the true purpose of bashcomp_alias? For now I only see error messages when trying to eselect bashcomp enable two aliases of the same script because of the same linkname. What benefit could one gain in aliasing their completion script to differnet names? In fact I find this confusing and highly contradicting, because you obviously can enable only one alias at the same time, but actually with enabling one you automatically enable all the others, since they are symlinks. Then why even bothering with those aliases? (Actual example: app-text/calibre-1.48-r1, which installs 14 or so aliases to the exact same completion script.) -- Flo

[gentoo-user] Dynamically change PORTAGE_TMPDIR via bashrc?
(This is my third E-Mail and I hope this time it gets through. Sorry to the
sysadmins if I caused you trouble with my rejected mails, I'm still trying to
get used to Mutt.)
Greetings,
let me quickly explain my setup: I use BTRFS snapshots and chroot to create
binaries of upgradeable packages with emerge. When I have some spare time, I
just need to install these binaries on my "real" system. While compiling, I
set PORTAGE_TMPDIR to a tmpfs mounted directory. When installing on my real
system afterwards, I set PORTAGE_TMPDIR to a "normal" directory on my hard
drive, since I won't gain anything from extracting a package to RAM, just to
immediately copy the contents back to the hard drive.
Now here is the tricky part: Since I do the compiling on temporary snapshots,
I tend to kill emerge and delete the snapshot, when I'm in a hurry and have to
shutdown my workstation. (PKGDIR of course is bind mounted to outside the
snapshot, so I won't lose the already finished packages.) When I later
"resume" my upgrade, there are several binary packages and several others that
still need to be compiled. With PORTAGE_TMPDIR still set to tmpfs, my RAM gets
cluttered with already compiled files from the binaries that may as well stay
on the hard disk.
Now, instead of simply changing my workflow (like for example not deleting the
snapshot prematurely in the first place ...) I want to have some fun and
wondered if there might be a possibility to change PORTAGE_TMPDIR dynamically,
based on wether I want to install a tbz2 or compile sources.
So far I've tried in package.env: "*/* merge_type.${MERGE_TYPE}.conf". But
this just gives me errors like "merge_type..conf not found", so obviously I
can't use such variables here. I guess, those tricks can just be played in
/etc/portage/bashrc. But when I try to change PORTAGE_TMPDIR in bashrc
(EBUILD_PHASE doesn't matter, problem occurs regardless), I always get errors
like "PORTAGE_TMPDIR is a read-only variable".
Now, before I try some crazy stunts like bind-mounting $D and $ED on "preinst"
and cleaning up in "postinst", I wanted to know if some of you guys did
similar experiments and/or have some advice that you could share with me.
Regards,
--Flo

I am aware that my setup might not be ideal and that approaches like bcachefs might help me creating a better compile-install-workflow. But for now -- just for the fun of it -- let's assume that the underlying basis is fixed and all that is left is finding a way to dynamically change variables like PORTAGE_TMPDIR. That could also be used for scenarios like "if the package needs to be compiled, then use every single machine in the local network as a distcc server; if there is already a tbz2 file for the given package, then just install it without searching for potential servers". Portage's bashrc can be a powerful script for several use-cases, but at the moment I am quite sad that I can't change environment variables in there. So, any other ideas? Regards, --Flo

I never had this experience with Cisco IOS. It may be worth updating the router and WAP firmware in case this was due to a bug. The router should never allocate IP addresses from its reserved IP address table, although it will not be able to stop PCs using these addresses themselves if they were manually configured so. I got this pre-configured router from my internet provider and I have *very* limited access to the configuration. I have no telnet and no ssh, as far as I can tell. For example, when I want to change my wifi configuration, I have to do that online on my provider's website, which obviously triggers some kind of over-the-air update to my router. After an automatic restart, the new (readonly) configuration shows up on my router. However, I *do* have access to the LAN configuration, including DHCP range and the like. And yes, you are right, if I reserve addresses, the router *should* not give these addresses away to other machines. I shouted at the router and telling her that, but she wouldn't listen. And if it is really a problem with the clients, then multiple Linux machines, multiple Android devices, Sony's PlayStation 4, and a lonely Windows laptop all share the same bug, namely wanting to have the same IP address via DHCP and failing to obtain another one. If I don't reserve addresses from DHCP range and use statically configured addresses outside the range with some computers, then there is no problem with DHCP and the other machines that connect. So I take this fact as my baseline and work from there. Besides, I like having configuration files on my computers, which I can exchange and adjust as I like, without the need to click through heavily overloaded router configuration WebApps. If it is a Cisco running IOS there should be SSH access to run CLI commands for it. If however it is a Cisco-branded cheap appliance, then it would probably not have any relationship with IOS, but it may be able to run OpenWRT or equivalent on its SoC. No SSH, no possibility to replace the firmware, no other way to connect to the internet. Sorry. Have a look at the documentation provided by netifrc, it is well commented with detailed examples: less /usr/share/doc/netifrc-0.5.1/net.example.bz2 I did multiple times, but obviously this specific syntax didn't reach my mind.

[gentoo-user] netifrc, configure by SSID and MAC simultaneously?
Hello! In my wireless home network I use a static IP for my machine. The regarding line in /etc/conf.d/net reads as follows (let's assume that my SSID is in fact "MySSID"): config_MySSID="192.168.0.10/24" Is there a possibility to configure this IP not only for this specific SSID, but also for a specific MAC address of my wireless card? I only want my "main" wireless card to have this static IP, if another card goes up and connects with the same SSID, it should be configured via DHCP. I tried the following: config_MySSID="dhcp" config_001122334455="192.168.0.10/24" I also changed the order of those two lines, but the SSID based config seems to "win" regardless. Also, if this config would actually work, then I would have this static IP in every network I change (this is not desireable). So I need a logical AND with those two variables, like so: config_MySSID="dhcp" config_001122334455_MySSID="192.168.0.10/24" This would mean the following: Connect to MySSID via DHCP, except when using the interface with the MAC address 001122334455, which should get a static IP. Not to mention that I indeed tried this last one, but it didn't work either. So, what are your thoughts? Is this possible via netifrc? -- Kind regards Flo

Do you want whichever NIC of your PC connects first to a specific SSID to always obtain IP 192.168.0.10/24 and any NIC which connects second to use DHCP? Not necessarily the first NIC, but the NIC with a specific MAC address, say 001122334455. But now that you mention it, as long as one NIC gets the static IP (but only for the specified SSID) and all the others will be handled by DHCP, I don't care which one of the NICs is statically addressed. Sorry for not being able to describe it well. What I am trying to achieve: I have a Raspberry Pi as a server, without monitor, without keyboard. Just a Raspi and a Wifi stick. I want the Raspi to use DHCP when I take it with me and power it on at my workplace. Thanks to Avahi I don't need to know the IP address it gets at my workplace. When I am at home, there are reasons why I can't rely on Avahi (Android Phones for example that do not have the possibility to resolve raspi.local). So I want it to have a static IP at home. Now, if for whatever reason I lose the connection to Raspi -- for example once my router at home freaked out and wouldn't let Raspi connect with a static IP -- I want to have the possibility to plug another Wifi stick into Raspi which then gets connected via DHCP, so I can at least connect to it. As I see it, I can't use config_001122334455, because I would not be able to connect at my workplace anymore (different network properties). I now use config_MySSID to get a static address at home, but what about a second Wifi stick being connected? It would use the same config and end up getting the same IP address that didn't work with the first stick. In general, it would be intersting to logically combine the configuration via SSID with the configuration via MAC. I can also think of a scenario where I have two wifi networks and two wifi sticks, each one getting a static IP on their connected network. But if I take the Raspi into another network, I would want NIC_1 to be DHCPed and NIC_2 to be nulled. I hope I could help you to better understand what I am trying to achieve and what my current problem is. If possible I want to solve it via pure netifrc, but I would also be happy if someone said that it isn't possible at all via netifrc, so I can stop researching in this direction and think of something different. -- Kind regards Flo

For any other gateway the Raspi will fall back to using dhcp. Something like this should work: # Define the gateway you want to configure gateways_eth0="192.168.0.254,AA:BB:CC:DD:EE:FF,192.168.0.10" # Define the default route for gateway 192.168.0.254 routes_192168000254_AABBCCDDEEFF="default via 192.168.0.254" # Define the IP and netmask when using gateway 192.168.0.254 config_192168000254_AABBCCDDEEFF="192.168.0.10/24" # Define the DNS servers to use with gateway dns_servers_192168000254_AABBCCDDEEFF="192.168.0.254" # Then you need to add a line for all other routers the Raspi may connect to: fallback_eth0="dhcp" NOTES = 192168000254 is the syntax used to represent an IP address for the home router of 192.168.0.254 AABBCCDDEEFF is the syntax used to represent a MAC address for the home router of AA:BB:CC:DD:EE:FF If your Raspi wireless NIC is not eth0, please adjust the fallback directive above accordingly. You may need to duplicate the above for any other NICs your Raspi may be end up with, for which you would want to configure a static IP address. Huh, neat. This looks indeed like it could be exactly what I was looking for. Thank you very much, I didn't know about this syntax! I'll try it the next days and report back afterwards! -- Kind regards Flo

That is a real nightmare. first of all, let me tell you that I am not a Haskell expert and the following is only based on my personal experience. I had similar problems with using pandoc, which also guides me in the "Haskell hell", as you call it. However, since I added 'dev-haskell/*' into my package.keywords, I have not experienced anything problematic anymore. As for rebuilds and preserved libs, sometimes (rarely) after big updates I get segmentation faults and the like with Haskell packages. Since I have "buildpkg" in my FEATURES, I can do the following: Remove the complete dev-haskell folder in my bin-package directory, plus maybe the packages, that depend on them, so app-text/pandoc or dev-vcs/git-annex. And then I recompile every package, that does not have a binary package present. This way, even if some packages fail because of OOM or the like, I can just continue where I left off, because the succeeded ebuilds created binary packages. I have never used haskell-updater, I never needed to. So, to summarize: - dev-haskell/* to package.keywords - use buildpkg when compiling/upgrading haskell Disclaimer: Your experience MAY vary. ;-) -- Regards Flo

Why is that?
it might possibly be related to hash randomization. I experienced a
similar "problem" during work some time ago, where I couldn't reliably
compare a set of values with a predefined list, without sorting it
first.
You can try the following Bash script to demonstrate the effects of hash
randomization in Python:
for _ in {1..5}; do python -c "print(set(['a', 'b', 'c']))"; done
Chances are high that you will get five completely differently sorted
sets.
Since Portage is programmed in Python, it might be the same effect here,
the packages are built up in a set or a dictionary and are therfore
affected by the random seed.

[gentoo-user] Sending HUP to OpenVPN after WiFi reconnect in Mesh
Dearest collective knowledge of gentoo-user,
I'm using netifrc with wpa_supplicant (no custom settings in netifrc)
for accessing a FRITZ!Box network at my parents house. They have some
WiFi repeaters set up, connected via AVM's Meshing capabilities.
Also, I am using OpenVPN to connect to VPN servers from ProtonVPN.
From time to time, I would see this in the syslog:

This happens even without setting "bgscan" or similar in
wpa_supplicant.conf, so I highly suspect, this is the magic of a Mesh
WiFi to pass me to a more fitting AP in the same network from time to
time. All fine so far, I don't lose WiFi connection, so this seems
normal to me.
What bugs me however is, that OpenVPN loses connection to the VPN server
after such an AP change and is not able to reconnect automatically
again.

The lines from 19:06:29 are repeated every 20 seconds
(server-poll-timeout 20), with varying IP addresses, so it seems to
cycle infinitely through all servers without success.
While this is happening, I cannot access the internet. I suspect, this
is because of the "persist-tun" setting in the OpenVPN config, but I
don't want to remove it because I'd rather have no internet at all than
having suddenly internet without VPN ("kill switch").
I can manually "repair" this situation by sending SIGHUP to OpenVPN,
which causes a hard reconnect.
Now, with this background information, I need your help to come up with
a strategy to survive an automatic Mesh WiFi reconnect, without the need
of manually restarting OpenVPN all the time.
- Might there be a problem with my OpenVPN config? I'm mostly using
the default config that can be downloaded from ProtonVPN, with some
additional "route" statements to make VPN unfriendly websites happy, and
I renamed the device name to have proper logs (see code block directly
below this bullet point). Has anyone a similar setup and did some
adjustments to make it work properly?

Re: [gentoo-user] Sending HUP to OpenVPN after WiFi reconnect in Mesh
Hi Hoël, thanks for your response! On 2024-01-03 18:11, Hoël Bézier wrote: I’ve encountered the same issue as you. I fixed it by removing the persist-tun option from my configuration file. The way I understand this configuration option, is that OpenVPN allows itself to destroy and recreate tun interfaces if needed. I’m not sure whether it means you may end up on the internet without going through your VPN. I tried again to remove the "persist-tun" option, and indeed I can now reconnect also via SIGUSR1 without problems. Also all traffic is blocked / dropped while waiting for the server timeout, so at least I'm not left open in the wild without VPN. I’d be very interested if anyone had further information on that matter, whether they would contredict my claims or support them. Yes, even though USR1 works now without falling back to no-VPN routing, if someone can give a little more insight if removing "persist-tun" is the way to go here would be nice! So at least one of the issues is "solved" for now, but the main problem still remains: How can I properly detect Mesh roaming and react timely to send HUP or USR1 to OpenVPN? I'm still thinking about some sort of wpa_supplicant "hook" mechanism for these roaming events, but I cannot find something like this in the docs ... Kind regards FloGa
