I haven't had to compile a kernel in 20 years.

Ah fuck, I just see that you are lemmy.ml tankie scum. Of course you are siding with autocratic fascists. blocked

Hey fuckwit, you didn't reply to a single thing I said.

Europe supported the Ukrainian people vocally, but verbally during the Maidan.

Russia armed and funded extreme Russian nationalists, you know like actual nazi scum, and sent them to Ukraine led by FSB officers, controlled directly from the Kremlin. Nobody in the Donbas asked for this, except for retarded nazi scum.

Fuck your disingenuous bothesidesism.

Western support of Euromaidan (what you erroneously call "meddling") isn't remotely comparable to the straight acts of war that Russia committed in the Donbas.

I live in a country that was occupied by Nazi Germany, where the Nazis did the exact same things and put the local Nazi sympathizers in charge of local administration. It didn't turn us into a country with deep Nazi roots.

We just imprisoned and shot those fuckers after the war.

Everything, because the people of D&L will not violently resist. They were peaceful citizens of Ukraine, who overwhelmingly voted for Ukrainian independence in 1991.

The Donetsk & Luhansk republics would violently resist any attempt by Kyiv to absorb them back into Ukraine.

LOL

You know that whole rebellion thing was created by Russia right?

You'll be lucky if there are actual VMs.

Mods should ban any account that has external links meant to sell something

There is r/nofans

I think cars peaked ca. 2010. Anything added after that are annoyances or things being taken away.

If I could get a brand new facelift E90, that would probably be my next car.

Do not allow username/password login for ssh

This is disabled by default for the root user.

$ man sshd_config

...
       PermitRootLogin
               Specifies whether root  can  log  in  using  ssh(1).   The  argument  must  be  yes,  prohibit-password,
               forced-commands-only, or no.  The default is prohibit-password.

If it is your single purpose to create a blocklist of suspect IP addresses, I guess this could be a honeypot strategy.

If it's to secure your own servers, you're only playing whack-a-mole using this method. For every IP you block, ten more will pop up.

Instead of blacklisting, it's better to whitelist the IP addresses or ranges that have a legitimate reason to connect to your server, or alternatively use someting like geoip firewall rules to limit the scope of your exposure.

I feel like we need to talk about Lemmy's massive tankie censorship problem. A lot of popular lemmy communities are hosted on lemmy.ml. It's been well known for a while that the admins/mods of that instance have, let's say, rather extremist and onesided political views. In short, they're what's colloquially referred to as tankies. This wouldn't be much of an issue if they didn't regularly abuse their admin/mod status to censor and silence people who dissent with their political beliefs and for example, post things critical of China, Russia, the USSR, socialism, ...

As an example, there was a thread today about the anniversary of the Tiananmen Massacre. When I was reading it, there were mostly posts critical of China in the thread and some whataboutist/denialist replies critical of the USA and the west. In terms of votes, the posts critical of China were definitely getting the most support.

I posted a comment in this thread linking to "https://archive.ph/2020.07.12-074312/https://imgur.com/a/AIIbbPs" (WARNING: graphical content), which describes aspects of the atrocities that aren't widely known even in the West, and supporting evidence. My comment was promptly removed for violating the "Be nice and civil" rule. When I looked back at the thread, I noticed that all posts critical of China had been removed while the whataboutist and denialist comments were left in place.

This is what the modlog of the instance looks like:

Definitely a trend there wouldn't you say?

When I called them out on their one sided censorship, with a screenshot of the modlog above, I promptly received a community ban on all communities on lemmy.ml that I had ever participated in.

Proof:

So many of you will now probably think something like: "So what, it's the fediverse, you can use another instance."

The problem with this reasoning is that many of the popular communities are actually on lemmy.ml, and they're not so easy to replace. I mean, in terms of content and engagement lemmy is already a pretty small place as it is. So it's rather pointless sitting for example in /c/linux@some.random.other.instance.world where there's nobody to discuss anything with.

I'm not sure if there's a solution here, but I'd like to urge people to avoid lemmy.ml hosted communities in favor of communities on more reasonable instances.

I have a small server in my closet which is running 4 Debian 12 virtual machines under kvm/libvirt. The virtual machines have been running fine for months. They have unattended-upgrades enabled, and I generally leave them alone. I only reboot them periodically, so that the latest kernel upgrades get applied.

All the machines have an LVM configuration. Generally it's a debian-vg volume group on /dev/vda for the operating system, which has been configured automatically by the installer, and a vgdata volume group on /dev/vdb for everything else. All file systems are simple ext4, so nothing fancy. (*)

A couple of days ago, one of the virtual machines didn't come up after a routine reboot and dumped me into a maintenance shell. It complained that it couldn't mount filesystems that were on vgdata. First I tried simply rebooting the machine, but it kept dumping me into maintenance. Investigating a bit deeper, I noticed that vgdata and the block device /dev/vdb were detected but the volume group was inactive, and none of the logical volumes were found. I ran vgchange -a y vgdata and that brought it back online. After several test reboots, the problem didn't reoccur, so it seemed to be fixed permanently.

I was willing to write it off as a glitch, but then a day later I rebooted one of the other virtual machines, and it also dumped me into maintenance with the same error on its vgdata. Again, running vgchange -y vgdata fixed the problem. I think two times in two days the same error with different virtual machines is not a coincidence, so something is going on here, but I can't figure out what.

I looked at the host logs, but I didn't find anything suspicious that could indicate a hardware error for example. I should also mention that the virtual disks of both machines live on entirely different physical disks: VM1 is on an HDD and VM2 on an SSD.

I also checked if these VMs had been running kernel 6.1.64-1 with the recent ext4 corruption bug at any point, but this does not appear to be the case.

Below is an excerpt of the systemd journal on the failed boot of the second VM, with what I think are the relevant parts. Full pastebin of the log can be found here.
