A slow website is like a slow waiter: it doesn’t matter how good the food is if the service is frustratingly sluggish. If your site takes too long to load, visitors are likely to abandon it faster than you can say “bounce rate.” But fear not! Here are some tips to help you optimise your [read more...]

I do have a server with dovecot and postfix. Postfix forwards the authentication to dovecot via smtpd_sasl_type = dovecot In dovecot I am using a passwd-file. Unfortunately the auth_mechanisms of my phone and my desktop client don't overlap. I tried an entry like the following in my passwd-file: me@my_mail.com:{SCRAM-SHA-256}4096,FgoufjZuloE+HyKPXD9H1A==,tSxnPOR0YNJDlEVWbq1+Ktvm6MtbKWzbQ2PLbW+tPlo=,r0RulB/9Fe+JjPzUWz0NBrEqJy5/IcAJAd2SGY8v7RI= me@my_mail.com:{CRAM-MD5}37a74a50ce0ad5aba39d4ce28ef4a882b740913447210328f2ea5f3dc611ac1e (Dummy entries for the fictional password Password123) Unfortunately only the first entry in the file works, so either scram-sha-256 or cram-md5. Is there any way I can get both to work at the same time?

I have a zfs pool with some NVME devices. In normal usage of that pool over network, the network is limitting IO and everything stays cool and quiet. But when I do a scrub it goes with max IO of the SSDs running at 10GB/s. The scrub is finished in few minutes, but the CPU fan goes high and the SSDs are getting fastly hot. I am not so much concerned about general server performance during scrub, I just want to slow itdown that CPU and NVMEs stay cool. I don't want to plug in the fan of my Asrock PCIe M.2 Adapter card again, as it would spin useless for all the other time. I've read about tuning options, but they seem to be focussed on guarenteeing responsiveness for other pool access. So I am unsure whether they could help. I have WD SN850X installed. The critical temp for them is according to smartctl 90°. The reported temp at the end was 70, bit the hottest of the three reported temp sensors went up to 88°. So I am unsure which sensor is refered to and

I have a user data script that changes the SSH port on an EC2 machine to 9000 to make way for a podman bastion container on port 22. This worked fine for several months, until today when it didn't. No changes to the script prior to this, and the EC2 AMI is Ubuntu LTS, so I am scratching my head as to what could have changed. I have added set -x to the top of the script and a few echos of command outputs, and I can see systemd is listening, but it doesn't connect to ssh. The sleep and extra restarts were added today to see if it was a timing issue. The ListenStream= is the official way to clear an existing port 22 binding. First the relevant bits of script: # --------------------------------------------------------------------------------------------------------------------- # RECONFIGURE HOST SSH TO PORT 9000 # --------------------------------------------------------------------------------------------------------------------- mkdir -p /etc/systemd/s

i really hate it when a documentation misses a part. Which is probably the case with the Redmine upgrade documentation: https://www.redmine.org/projects/redmine/wiki/RedmineUpgrade I have done multiple Redmine upgrades already, but always into a new, freshly installed VM/OS. This time i thought i can just upgrade "side by side" of the old versions as my OS was already the latest version. So i unpacked the latest Redmine Install-archive into a folder /opt/redmine6.0.6, side by side to my old /opt/redmine/ installation that holds a working Redmine 5.0.13. I've copied over the two conf-files and have done those few "bundle"-cmds, like decribed in the manual and everything wen't smooth. Permissions are correct, no error shown, everything fine. But after a restart the website still showed me the old Redmine version. After scratching my head

We are currently facing strange issues while setting up Exchange Classic Hybrid configuration. We use a dedicated Windows Server 2025 / Exchange SE, which is added to an existing Exchange 2016 cluster (1 DAG / 2 CAS). As we try to run the Hybrid Configuration Wizard it fails while creating the migration endpoint. After digging around in Exchange, we found a strange issue: The hybrid server refuses connection with HTTP 401.0 Unauthorized. Running Test-MigrationServerAvailability from Exchange Online shell it returns a mentioned 401 error: # Executed in Exchange Online shell # $c = Get-Credential -> domain\localExchangeAdmin Test-MigrationServerAvailability -ExchangeRemoteMove: $true -RemoteServer 'exomail.company.com' -Credentials $c Result : Failed Message : The connection to the server 'exomail.company.com' could not be completed.

I'm implementing Kerberos authentication for a business application layer access to let the users authenticate with an external active directory using LDAPS. My implementation follows the article below, chapter 1, paragraph What is Kerberos?. I need to know which tcp and udp ports are required for the flows 5 + 6, between the client application and the service server (not domain controller).

I am trying to change the score of this rule RECEIVED_BAD_HELO as many emails use relays doesn't match reverse DNS of IP. root@web:~# spamassassin -V SpamAssassin version 3.4.6 running on Perl version 5.32.1 While chatting AI to help, I have tried to modify in vim /etc/mail/spamassassin/local.cf with several different rules types for score but it just never worked. I am explained that SA has something built it that overwrites whatever I try for this rule. Here are some details # RECEIVED_BAD_HELO was scored 4.0 #score RECEIVED_BAD_HELO 1.0 #SpamAssassin 3+ sometimes defines subtests or meta rules for certain tests (especially network/RCPT/HELO checks). # #In your debug log, you can see hundreds of subtests running (tests_pri_-2000, tests_pri_0, tests_pri_500, etc.). Some of them are internal checks like LASTEXTERNALHELO, SENDERDOMAIN that may multiply the score or force a minimum. # #In other wo

I have a high traffic set of 6 openresty servers that log (error.log and access.log) into a local mounted NFSv3 share from NetApp. My logrotate is: # cat /etc/logrotate.d/nginx /usr/local/openresty/nginx/logs/*log { daily copytruncate delaycompress rotate 14 missingok notifempty compress } When logrotate kicks in the copytruncate will copy the file to a tmp file within the share ( 1 ) truncate the old one rename the tmp file to the right name compress it which means take it to the server and return it compressed . ( 2 ) This means logrotate will need to copy the big log file from NFS to the server at ( 1 ) and ( 2). I understand that with this setup I can not avoid ( 2 ) but I could avoid ( 1 ) doing an mv in place and creating a new one; however I can't find a way for logrotate to do it. Can someone please enlighten me on how to avoid

I have a dual boot laptop and want to simplify backups of the entire laptop disk to an external drive. I boot the clonezilla.iso using a Ventoy modified external hard drive. I believe that since I am not using grub to boot the clonezilla ive iso, that I will be modifying "Z:\boot\grub\grub.cfg". I have the iso mounted on Z:\ in Windows. I have searched but most were too complicated for me and none used Ventoy to boot the image. The last two times I backed up with the live iso, I got this set of commands "to use the next time ..." /usr/sbin/ocs-sr -q2 -c -j2 -z9p -i 0 -sfsck -scs -senc -p reboot savedisk 2025-08-17-09-img sda I will be backing up the entire /dev/sda hard drive sda1 through sda8 which boots either Ubuntu or Windows 10. I'm booting Ventoy-Clonezilla from a hard drive /dev/sdb via Ventoy.
