Title says it all.
How can I, with iptables, log all IP connecting to a server? As a little detail, I'd like to have only ONE entry in the log PER DAY PER IP.

It does not happen often, but sometimes after running the below script, checking the iptables with service iptables status shows that they weren't updated and the script doesn't output any error.

Hi all,
I'm setting up port forwarding for an L2TP VPN connection to the local Windows 2003 VPN server. The router is a simpel Debian machine with iptables. The VPN server works perfect. But I cannot log in from the WAN. I'm missing something.
The VPN server is using a pre-shared key (L2TP) and…

I was thinking initially needing to do a reverse proxy or something so I could get some SSL/TLS traffic look like it is being terminated at a server and IP address in the AWS cloud, and then that traffic is forwarded onto our actual web servers that aren't in the cloud...
I've not done much iptables…

I just set up LogRotate on my RHEL6 server so that it rotates my custom Apache log files. However, it doesn't do anything when i try manually running it.
I expect it to rotate the log files "access.log" and "err.log". They have been there for a few days and need to be rotated.
Here is the output:

I have problem with starting PostgreSQL 8.4 on Ubuntu 9.10 Server after blackout. When I try to connect to the database it says:
psql: server closed the connection unexpectedly
This probably means the server terminated abnormally before or while processing the request.
When I try to start it by…

Recently, I opened up the SSH port through my firewalls (and redirecting to my server) so I could check on the (http) server while on the road. The first week or two there was nothing different. But now, three or four weeks later, I see lots of this:

I'm sure there's a lot of questions on here similar to this, and I've been reading them, but I still feel this warrants a new question.
I want nightly, incremental backups (full disk images would waste a lot of space - unless compressed somehow.) Preferably rotating or deleting old backups when running…
