I think you have 2 problems. first one is with TLS; the file /etc/ssl/certs/ca-certificates.crt is missing, or can't be read by postfix. Make sure the file exists and is readable. My be something went wrong with the installation. You could try to copy it from another machine. Second problem is with ...

Re: tar (child): bzip2: Cannot exec: No such file or directo

sound to me that bzip2 is not installed on your system.

check for the command bzip2

if you can find it, install it on Debian (or ubuntu) with

Code: Select all

apt-get install bzip2
If you use another flavor of linux, either use yum (CentOS, RedHat, mandrive, ...) or emerge (gentoo)

Re: DNS-server used in DDOS attack

The same can happen if you are running a NTP-server (Network Time Protocol). This service is less common to be set on a web-server then a DNS-server. But if it is running it can also be (mis-)used to setup a DDoS-attack. The easiest solution is to upgrade to the latest version (at least 4.2.7p26). M...

Re: read piped info into a script

I think piped info is just as standard input.

Something like this should work

Code: Select all

MESSAGE="$(< /dev/stdin)"
Standard input get stored in variable MESSAGE

You can test the script with this
echo "this is a test" | script.sh

Re: Increment a number in database

You can try the following, it should work in MySQL:

Code: Select all

UDPATE table SET num= num +1 WHERE id='x';
This way MySQL is doing the counting, and not your application or script.
Doesn't have to +1, it can do any counting.

Re: Change the timezone for a script

You can use the date_default_timezone_set() function

Code: Select all

date_default_timezone_set('America/Los_Angeles');
print date("Y-m-d");
date_default_timezone_set('Europe/Brussels');
print date("Y-m-d");
