Exim4 tls
sid:/etc/exim4# /usr/share/doc/exim4-base/examples/exim-gencert
[*] Creating a self signed SSL certificate for Exim!
This may be sufficient to establish encrypted connections but for
secure identification you need to buy a real certificate!
Please enter the hostname of your MTA at the Common Name (CN) prompt!
Generating a 1024 bit RSA private key
...................................................................++++++
.......++++++
unable to write 'random state'
writing new private key to '/etc/exim4/exim.key'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Code (2 letters) [US]:PL
State or Province Name (full name) [Some-State]:Lubelskie
Locality Name (eg, city) []:Lublin
Organization Name (eg, company; recommended) []:G
Organizational Unit Name (eg, section) []:unSecurity
Server name (eg. ssl.domain.tld; required!!!) []:grendel.ar.lublin.pl
Email Address []:eyck at grendel.ar.lublin.pl
[*] Done generating self signed certificates for exim!
Refer to the documentation and example configuration files
over at /usr/share/doc/exim4-base/ for an idea on how to enable TLS
support in your mail transfer agent.

Running proftpd with tls
Under woody:
$ openssl req -new -x509 -days 365 -nodes -out ftpd-rsa.pem -keyout ftpd-rsa-key.pemWith sid/sarge you also need those in proftpd.conf:
#TLSCACertificateFile /etc/proftpd/ftpd-rsa.pem TLSRSACertificateFile /etc/proftpd/ftpd-rsa.pem TLSRSACertificateKeyFile /etc/proftpd/ftpd-rsa-key.pem TLSLog /var/log/proftpd/tls.log TLSRequired on TLSEngine on

Making linux reboot on panic
Suppose you're running some unsafe kernel in remote location, you wouldn't like your machine to freeze waiting for you to power it down in case of panic. So what do you do?
echo "69" > /proc/sys/kernel/panicthis will make it wait 69 seconds and then reboot in case of panic ( unless of course, like with my problem with audio half of panics loop infinitely )
