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

Ran into a weird problem, and this seemed a good forum to toss it out into -- if I've gaffed, please let me know. Just upgraded my RH5.0 box to RH5.2. Went well, worked nearly seamlessly. When running 5.0, though, I'd installed the opie-fied ftpd that comes with the most recent opie package (ftp://ftp.inner.net/pub/opie/opie-2.32.tar.gz) and had it work without a hitch. I'd also

Hi, When php3 module is compiled in apache, files in any directory will be interpreted by the parser and executed. This is a security breach. There is a way to correct this? Any comments?

Hi Are there any known security holes or necessary precautions in using port forwarding with ipportfw? I'm planning on forwarding ports from an outer firewall/router (connected to the Internet) to a host in the DMZ, then on from the DMZ host to the inner firewall, and finally from the inner firewall to some host on the inside. Thanks, Jens jph@strengur.is From mail@mail.redhat.com Wed

This may be, or may not be a security issue, however, since alot of people still use tripwire-1.2 or lesser versions(this is what shipped with R.H. Linux 5.2 at least), they might be interested in following detail: Chuck Campbell (campbell@neosoft.com) pointed me out that tripwire dies with coredump on R.H. linux, if it hits a filename containing 128-255 characters. Playing a bit with debugger I

Hi everyone, I'm trying to rsync a large directory. After pondering on the list-of-files, it's now more or less doing nothing. It's running for over 4 hours now, not doing anything except eating CPUtime on the destination for over half an hour. I don't know what it was doing before that. The stdout of the rsync reported: 4675350 files to consider (which is about right)

Hi rsync team, I thought that rsync would try to overlap computing and IO on both machines. I'm rsyncing a large tree (18G) and am keeping an eye on that. Suddenly my side completely stopped. No IO visible, no CPU time spent. The otherside was doing 100% CPU. Then the other side started to do disk IO. Then suddenly the activities moved over to my side, and I saw things moving again in the

Hi, I Emailed this afternoon that bwlimit leads to a much too low bwlimit if small amounts of data are sent in each write. I wrote a small patch now. Congrats on the code: It's nice and clean: I wrote a working patch in 5 minutes after examining a total of 25 lines of code. (My backup used to require two hours of small sleeps alone, which should be reduced by a factor of 8....)
