I want every packet or packet fragment to be logged that comes to my server.

"Is there a log" - probably not.

How to make one - use snoop. Man page description:
snoop captures packets from the network and displays their
contents. snoop uses both the network packet filter and
streams buffer modules to provide efficient capture of pack-
ets from the network. Captured packets can be displayed as
they are received, or saved to a file (which is RFC 1761-
compliant) for later inspection.

Warning - you better read the man page, know what you are doing, or have more disk space than EMC. Snoop will fill up a disk quickly if you leave it running all the time. Plus, you would never have the time to go through all the data - learn to use it, and then filter out what you don't need.

I think you can Sniffer...Because It can View and Capture every Packet in your network...

Or, you can just use ipchains for this:
/sbin/ipchains -A input -l -p all
/sbin/ipchains -A output -l -p all
and then set a script to parse /var/log/messages (default for syslogd to send log entries from ipchains):
cat /var/log/messages | grep "Packet log: input" > $HOME/input_log
cat /var/log/messages | grep "Packet log: output" > $HOME/output_log

Then just save these files off-site. However, lots of ppl just like to use someone's tools to do the same thing, but hey, ipchains comes with a lot of distros nowadays, why not use it? ;-)

if you want to build advanced logging and to analyze automatically whether there are attacks or similar, just try SNORT. This is an Open Source IDS (Intrusion Detection System). Please note that it is better to shutdown all unnecessary network services in your servers. It makes everything easier.
