redirecting domain to subfolder with .htaccess

I’m new to using and changing the workings of a server and all that. So far I’ve only had one server with one domain for myself, but now a business is getting some traction and I want to use a different domain for it while keeping it on my server.

The situation is like this:

I have the main domain and root directory like I also just bought

The files for are within

I have established a forward from to already, but I can’t access sites via the url.

For example:

I wan’t to type and access while maintaining the link in the adress bar.

When I try it now I always end up in and never in the file I specified in the url.

I’ve tried working around it with the .htaccess file, but don’t really know much about it. What I have now is

RewriteEngine On RewriteCond %{HTTP_HOST} (www\.)? RewriteRule (.*)$  1 [R=301,L] 

Sorry for the noob question, I really don’t know much about the topic and I’m not sure what to google to get what I want.

how to setup ssh tunnel to named virtual host

I’m currently setting up server inside our lab at Uni that will be used for multiple purposes including a bibliography database and a CI Server (Jenkins). In order to maintain clean separation of concerns, I have a jailed virtual host for each function along with an assigned internal domain name. Inside the lab, the arrangement works fine.

However, in order to connect to our lab from home, we need to first VPN into the Uni and then SSH into our lab’s gateway machine. From the gateway we can access any internal machines we need to reach, and use SSH Tunnels as needed.

I’m wondering if it is possible to access virtual hosts through a single SSH tunnel? Like Server Name Indication (SNI)? Or would I need to setup a proxy server like Squid? I gather that both DNS as well as HTTP traffic would need to be routed correctly. Can this be done using just hosts file settings?

Any advice would be much appreciated. Thanks!

How to split a file with round robin

I am reading the split –help but I am unsure how to execute this command with the round robin feature, can someone please give me an example

Usage: split [OPTION]... [FILE [PREFIX]]  -n, --number=CHUNKS     generate CHUNKS output files; see explanation below  The SIZE argument is an integer and optional unit (example: 10K is 10*1024). Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (powers of 1000).  CHUNKS may be:     N       split into N files based on size of input     K/N     output Kth of N to stdout     l/N     split into N files without splitting lines/records     l/K/N   output Kth of N to stdout without splitting lines/records           --> r/N     like 'l' but use round robin distribution     r/K/N   likewise but only output Kth of N to stdout

Wireguard sends packets with source port 1 when using second routing table

I have a small home server in my basement that’s connected to a router and my home network. As my cable ISP only offers public IPv6 addresses and IPv4 is behind a carrier grade NAT I bought myself a public IPv4 address using a OpenVPN connection to a third party. As the contract with the latter provider includes some traffic limitations I only want to route the “public” server traffic over the VPN connection. All in all, it looks like this:

-------------------------- | WG Host                | |------------------------| | eth0:    | <- dhcp, home network, default gateway | tun0:   | <- vpn with public ipv4 address, gw for public services | vmnet:     | <- virtual machines, server daemons | wg0:    | <- wireguard -------------------------- 

Most services I have are on the vmnet subnet, ssh (on port 110) and wireguard (on port 123) are supposed to run on the host. I have set up a second routing table and route all traffic with source ports like 80 or 443 over the VPN connection unless an internal client connects to the services, because I do not want to route all that traffic over the internet when in fact the server is right inside my home network. To be able to do this, I’ve come up with some rather complex iptables-rules:

iptables -A POSTROUTING -t nat -o tun0 -j MASQUERADE  # Always set source IP to VPN ip, so home network clients do not get confused iptables -A POSTROUTING -t nat -p tcp --sport 80 -j SNAT --to iptables -A POSTROUTING -t nat -p tcp --sport 443 -j SNAT --to  # public services, default gateway via vpn iptables -A PREROUTING -t mangle -p tcp --sport 80 -j MARK --set-mark 2 iptables -A PREROUTING -t mangle -p tcp --sport 443 -j MARK --set-mark 2  # Do the same for ssh & wireguard (123/udp) iptables -A OUTPUT -t mangle -p tcp --sport 22 ! -d -j MARK --set-mark 2 iptables -A OUTPUT -t mangle -p udp --sport 123 ! -d -j MARK --set-mark 2  ip rule add fwmark 2 table 2 ip route add default via dev tun0 table 2 ip route add dev vmnet table 2 ip route add dev eth0 table 2 

This works pretty well for the vmnet services and ssh, but wireguard’s behavior seems to be a little bit strange: It works inside my home network, but when I try to reach it from the outside, it won’t work. When doing a tcpdump on tun0 I can observe that the client’s packets reach wireguard just fine. The answering packets are obviously sent on tun0, too (so routing seems to work). The strange thing is that Wireguard sets the source port of these packets to ‘1’. Unfortunately, they never reach the client. I suppose that is because the NATs in between don’t manage to match the (srcport,dstport) combination anymore.
