    How to increase Receive-Buffer (RX-Buffer) in LXC Container?

    PVE 8.4.1 Debian 12 LXC VE also Debian 12 NameServer on VE is under a so called pseudo-random subdomain (PRSD) attack. Basically a bot-net is flooding DNS w. MASSES of silly requests. The VE is at 98% idle but legit requests do not come through, apparently due to the Receive- or RX-Buffer...

    Did Kernel 6.2.16-5 kill IPMI? How to fix?

    search in quarantine by domain?

    Is there any way to search in SPAM Quarantine "by domain" rather then by email-address? I'd like to check all quarantined emails under a certain domain, not for a certain user. Tried '*domain.tld', '*@domain.tld', '@domain.tld', 'domain.tld', 'domain' but it shows only the list of (numerous)...

    User got this SPAM over the weekend. Countless, basically identical mails got through and we had similar cases in the past. He has catchall email for this Domain and X-Original-To went to random addresses @his.Domain, while the To:-address is on a totally unrelated Domain. How did the SPAMMERs...

    How did that one manage to get passed the SPAM filters?!

    'zfs destroy' of single disk killed all VEs

    with disk-space having become short, I wanted to clean up my server a bit. I deleted a virtual disk, that was not actually being used (VE1100 uses subvol-1100-disk-2) and could not be deleted via GUI, so I did a: zfs destroy -f rpool/subvol-1100-disk-1 as a result all other subvolumes sort of...
