I have a firewall that forwards port 2222 to a Linux machine running SSH server on port 2222. The problem is I do not know what the IP of the firewall is. So I want to scan the subnet to tell me which IP has this forwarded port.

I tried this script:

#!/bin/bash

for ((i=2; i<256; i++));
do

        sudo nmap -sS -p2222 10.1.$i.0/24
done

The output of this is a lot of this:

Host is up (0.00039s latency).
PORT     STATE SERVICE
2222/tcp open  EtherNetIP-1

For 256x256 hosts this is what I see. I think this answer could be one of two answers:

1. What should the output be? Maybe I missed it and must grep for it.
2. What is a different nmap scan I should use?

Sometimes I notice the server is running slowly and at those times a ps -e shows that logger and tee are running but I can't think of why. Is this a known issue? Why would these need to run without being called? When this happens there are very few systems running, but there is some connection to running Chromium maybe but I am not sure.

I am using ssh-keyscan in a shell script to accept keys for hosts. The hosts are identified by hostname but not in /etc/hosts. They are in ./ssh/config so I can ssh <hostname> but I can not ping etc.

It looks like ssh-keyscan is not using the .ssh/config file and that seems funny.

Can someone confirm this happens to them?

Real question: Does someone have a way to make ssh-keyscan use ~/.ssh/config?

When I install teamviewer_amd64.deb in a Debian VM it installs with no error.

I start "teamviewer" and I see this:

$ teamviewer

Init...
CheckCPU: SSE2 support: yes
Checking setup...
Launching TeamViewer ...
Launching TeamViewer GUI ...

$

So it returns me to the command prompt and I don't see TeamViewer running anywhere like I used to see on TeamViewer 12.

I have never used WebDAV before (I like sshf) but I am trying it. I want to mount a remote WebDAV share that I set up on my server, on my local computer.

If I try as non-priv user I can't access mount command fully.

If I try as root I can't access the folder as user. I used this command: sudo mount -t davfs -o noexec https://nextcloud.example.com/remote.php/webdav/ /mnt/dav/

I don't want to use /etc/fstab because I don't want the share to be mounted before I establish a VPN (but I do want mount -a in rc.local)

Is there something like -o idmap=user I can use for WebDAV?

Using Linux obviously.

I have a server that runs OpenVPN on it's primary IP.

There is also a second IP I connect to using SSH as a SOCKS5 setup like this:

ssh -C2qTnN -D 1337 me@<secondary-ip>

I go to whatismyip.com from each connection and I want to see the primary IP when I connect through the VPN and the secondary when I connect through the SOCKS5 proxy (assuming my browser is using the proxy obviously) but now always the primary IP shows.

What trickery do I need to do to fix this?

Edit: this is on a vps and the different IP addresses are on interfaces venet0:0 and venet0:1

What is the difference between conf-enabled and sites-enabled (or conf-available and sites-available if you want to think of it that way)?

When should a file go in one but not the other?

Are they read into apache2 differently or at different times?
