Hi there. I've been using Dovecot for quite some time now but I just started using Let's Encrypt certs. Since LE certs are renewed automatically without user intervention I'm wondering if I will need to restart dovecot after that renewal... Has anybody had any experience with that? Thanks so much for your help! Ignacio -------------- next part -------------- An HTML attachment was

Automatic renewal The Ubuntu package for certbot comes pre-configured with systemd timer that will automatically renew existing certificates. What it does not handle however is reloading postfix/dovecot so that they will begin using the new certificates. For that, we need to implement a hook. Certbot has both pre and post hooks that you can use to execute a script prior to and after the renewal

Hi, I get my Email from my own SMTP server on the internet using "fetchmail". Some time ago I did the smart thing and configured dovecot to use SSL and the letsencrypt certificate that automatically renews. Welllll..... a few days ago my certificate expired and the fetchmail deamon running in the background had nowhere to complain. So I didn't notice. It turns out that dovecot

We are using tmux, screen and x2go to run long-running jobs on our compute servers. $HOME and other data should be mounted via CIFS or NFS4. Because such a job can run for more than a week, I would like to increase the Kerberos ticket lifetime or better the Kerberos ticket maximum renewable lifetime. I found this guide: https://wiki.samba.org/index.php/Samba_KDC_Settings Unfortunately, only settings that are smaller than the following have an effect: kdc:user ticket lifetime = 24 kdc:renewal lifetime = 24 There appears to be an upper limit of 24 hours that none of these settings...

Hello! Certificates from letsencrypt are renewed every three months. Does that mean a MUA has to accept the renewed certificates manually everytime it is renewed? Sorry if this is OT! Greetings Andreas

Hi all, I have setup icecast to work with letsencrypt ssl certificate, this works fine. But now I am struggling a bit on how to renew the certificate every 3 months. As per letsencrypt recommendation I run a cronjob to check for renewal every day, problem is when there is a new certificate Icecast needs to be restarted to pick it up, as the certificate only seems to be loaded at startup of

Install letsencrypt and request a certificate specifying the webroot of your Icecast server and the host.domain: certbot-auto certonly --webroot --webroot-path /usr/share/icecast2/web/ -d icecast.domain.name Now you should have a certificate for your server, it's only in the wrong format for Icecast, copy the key and the certificate to 1 file with the following cmd: cat

Hi, Would anyone have any idea as to why I would obtain completely different results when subsetting using the subset function vs bracket notation? I have a data frame with 65 variables and 4382 rows. When I use execute the following subset command I get the correct results (125 rows) > subset(df, Renewal==TRUE, 1:2)   However, I tried to obtain the same results with bracket notation as

Hi Ralph Boehme, A new system is installed with Ubuntu 24.04.1 and Samba 4.19.5 My hotfolderscan.exe tool runs now on a Windows 2022 system and use the Ubuntu 24 system as Samba share. The hotfolderscan tool has to run 10 hour before the Kerberos ticket renewal. Both on the Ubuntu 24 and the Windows 2022 system, Wireshare is catching the network packages. Tomorrow I hope to see the result. I
