TXT_DB error number 2 failed to update database

While signing a certificate for a new OpenVPN user, I received the following error message which stops the whole process (exit code 1)

Certificate is to be certified until Nov 6 08:53:05 2023 GMT (3650 days)
Sign the certificate? [y/n]:y
failed to update database
TXT_DB error number 2

Problem:
Because you have generated your own self signed certificate with the same CN (Common Name) information that the CA certificate that you’ve generated before.

Enter another Common Name.

Debian disable IPv6

Since Debian 6 (squeeze) this is the working method to disable permanent IPv6 implementation. This method is also reboot safe.

cat /etc/sysctl.d/disable-ipv6.conf
net.ipv6.conf.all.disable_ipv6=1

cat /etc/sysctl.d/disable-ipv6.conf net.ipv6.conf.all.disable_ipv6=1

If you have no possibility to restart your system yet, this change can be made immediately work by executing:

sysctl -p /etc/sysctl.d/disable-ipv6.conf

sysctl -p /etc/sysctl.d/disable-ipv6.conf

Anothe method – perfect for firewall scripts:

echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6

echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6

Set TimeZone in Fedora

I forgot to set the correct time zone as I installed my new Fedora 18 system.
So this can be also done after the completed installation:

1
ln -sf /usr/share/zoneinfo/Europe/Berlin /etc/localtime

ln -sf /usr/share/zoneinfo/Europe/Berlin /etc/localtime

The localtime symlink will show to the proper timezone file.

RSS

Two days after I installed Tiny Tiny RSS (ttrss) v1.7.2 was released a new version of it 1.7.4. Thats great!

To be able to install Update from preferences are some fixes in config.php required. Maybe its only my problem!?; but my updater was not active. [Read more…]

Mac OS X 10.8 flush DNS cache

February 25, 2013 by Igor Drobot Leave a Comment

DNS-Cache

I came across this Apple specific DNS cache situation this morning.
I changed a DNS record for my GIT-server and was trying to access it again, the DNS was still showing the old IP-Address. After some attempts to clear Linux DNS cache with “rndc flush” I recognized that dns is was cached by my Mac.

Mac OS X keeps a local cache of successful resolved DNS queries for a time defined by the DNS server.

To clean DNS Cache in Mac OS X versions 10.7 and 10.8, run this command from your Terminal:

1
sudo killall -HUP mDNSResponder

sudo killall -HUP mDNSResponder
