I have two gateways in my subnet. 192.168.1.2 - main 192.168.1.1 - secondary (yeah that's not a mistake)

So I am using 192.168.1.2 everywhere as default route

Is it possible to configure danted so it will forward outgoing connections to the secondary gateway (192.168.1.1) while main system will use main gateway? Or should I do some tweaking with iptables to achieve that?

Other possible solution is to do an lxc container with different network stack, but I am trying to achieve same goal on rpi with not much RAM and without that kind of redundant solutions.

So I wonder if it supports that out of the box, or maybe I can split network stack without any virtualization? (create virtual interface with other gateway maybe and then pass that secondary interface to danted)

Thanks

I am using nginx as a reverse proxy.

Is it possible somehow to access response page content as a variable to disable caching for a pages that have specific word in content (not in header) WITHOUT modifying backend?

Any way would be appreciated including inline perl, lua or even piping page content to php script that would parse the content.

I can even make a dirty code hack if someone could show me a source file which parses page response and any idea what I can change in that file (add no cache headers or just hack some other variable that corresponds caching)

I accidentally deleted my LVM partition inside /dev/md1. The good thing that my linux root partition and swap inside this LVM are still mounted. I was able to copy all data to my backup HDD, and was able to do a dd copy of my LVM root partition.

Now gparted on /dev/md1 shows that all space is unlocated. If I reboot my pc I will loose ability to boot it again. Is there any way to quickly recover partition table without reinstalling system? Keep in mind that LVM still knows the partition table, I am able to read and write to that non-existent partitions.

Thanks

Is it possible to detect rx+ rx- tx+ tx- wires of an ethernet cable having only a part of cable with multimeter or somehow else?

I mean the situation when you have just one side of the ethernet cable. The other side is connected to a working switch or hub far away. And the guy that did the other side of the cable didn't use standard wiring (green and orange pairs).

I am talking about 100mbit cables, not 1000mbit.
