MySql-Server Installation Problem

Sliding years...

Yesterday, I run into the same problem while upgrading 2.2.35 to 2.2.36.

The solution was...

1) For the security reasons, I had deinstalled bind9 because I have another server managing DNS for my IPs

=> After reinstalling for that upgrade (maybe this was not necessary!) my directory /etc/bind/ has to be symbolic relinked as described in the 'Perfect Server Setup...'


2) After reading several guides I had changed some setting in the /etc/sysctl.conf

=> Therefore, I commented out following lines:

Code:

#
# Turn on Source Address Verification in all interfaces to
# prevent some spoofing attacks
# Note: Make sure that /etc/network/options has 'spoofprotect=yes'
net/ipv4/conf/all/rp_filter = 1
#
# Do not accept IP source route packets (we are not a router)
net/ipv4/conf/all/accept_source_route = 0

#npe 100517 corresponding to tiger failures
#http://www.linuxquestions.org/questions/linux-security-4/how-to-resolve-tiger-fail-621670/
#http://www.securenetwork.it/ricerca/whitepaper/download/Debian-Ubuntu_hardening_guide.pdf
net/ipv6/conf/all/accept_source_route = 0
net/ipv6/conf/all/accept_redirects=0
net/ipv4/icmp_echo_ignore_all = 1
#npe
# TODO what about /etc/network/interface-secure  ?
#kernel.domainname = example.com
net/ipv4/icmp_echo_ignore_broadcasts=1

And execute:

Code:

#syscp -p
#/etc/init.d/rsyslog restart
#/etc/init.d/bind restart

Now, the upgrade worked fine. Afterwards, I reactivated the lines in /etc/syscp.conf


Maybe this works for other too.
