Different OS Kernel Update Frequency
Hi guys
I'm trying to configure a collaboration suit (PHP, PostgreSQL, Apache) plus a mail server(Sendmail and Dovecot) on a single box. It will be used heavily 24*7. So having a long up time is really needed. I'm looking for 3 to 6 month up time. I want to know about kernel update frequency(because they are causing server reboot) for different operating systems such as Linux(CentOS, Debian, Ubuntu Server Edition), FreeBSD NetBSD, OpenBSD.
Could anyone help? I'm not trying to make a Linux vs BSD question as it is against forum rules.

poppassd
POPPASSD(8) POPPASSD(8)
NAME
poppassd - Password change server for Eudora and NUPOP mail clients
DESCRIPTION
poppassd runs from inetd and listens on TCP port 106 by default. Its sole purpose in life is to engage in short FTP-like conversations
from client applications and execute (or deny) remote password changes via the PAM facilities configured in /etc/pam.d/poppassd. The con-
versation looks something like this:
200 poppassd v1.8.4 hello, who are you?
user adconrad
200 Your password please.
pass foo
200 Your new password please.
newpass bar
200 Password changed, thank-you.
quit
200 Bye.
As can be seen from the example above, unencrypted passwords are transmitted over the network. Because of this, it is recommended that you
use this daemon only for local loopback password changing (for instance, from Perl, Python, or PHP web applications on the same server) and
block all non-local access to port 106, either via tcpwrappers (/etc/hosts.deny) or with appropriate firewall rules.
If sending unencrypted passwords over the wire doesn't bug you terribly much (as in the case of an ISP with hundreds of POP3 mail
accounts), this daemon can provide a simple way for some of your clients (those running mail clients that actually support this protocol)
to easily change their passwords.
FILES
/etc/pam.d/poppassd
Contains the PAM configuration for poppassd. By default on Debian, it merely includes the common-auth and common-password files,
which should work in most cases. If this doesn't cut it for your site, tailor to suit.
