## virtualhost – Something wrong configuring apache to serve virtual host in local domain on LAN

I am using Apache 2.4.29 on Ubuntu 18. With a default domain, Apache worked fine but I am trying to configure additional subdomains. This is my virtual host configuration:

adam@gondolin:~$cat /etc/apache2/sites-available/edoras_mysql.conf ServerName edoras_mysql.gondolin.localdomain ServerAdmin webmaster@localhost DocumentRoot "/var/www/edoras_mysql" ErrorLog${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined  The default setting does not change. i ran a2ensite edoras_mysql and did not complain, and restarted the Apache demon, however, browsing the site results in: We can’t connect to the server at edoras_mysql.gondolin.localdomain. Of the same machine. Browsing gondolin.localdomain Although it is working. This is my /etc/hosts: adam@gondolin:~$ cat /etc/hosts
127.0.0.1   localhost localhost.localdomain gondolin
127.0.1.1   gondolin
192.168.0.3     gondolin.localdomain gondolin

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters


If I have done something basic wrong, I do not see it. This is what I should have according to everything I read on the net.

I am using this gondolin host like DHCP and DNS server, and gateway with iptables that works fine, so I don't see any problem with that.

## networks – Gigabit lan does not go beyond 140mbs outside of sandbox vm

I'm sorry for bad English. I have a gigabit connection (940mb day1 700mb tested with the port of my laptop today) my motherboard is msi z170 gaming m5, the lan port is e2400 atheros killer, the cable is cat6, the segment is gigabit and it always worked. For a while now I found that the connection is not as fast as ever. I found my speed test at 140 MB, tried to update the drivers, clean them and install them from scratch, with no luck. Then I thought the LAN port was broken or something because I tried the same configuration with the same cable, etc. With my laptop and the test speed was 700mbs, so I ordered a 3.0-gigabit USB from Amazon Basic. and the results were the same … then I thought about trying the new sandbox virtual machine with Windows 10 1903. and … the results were more than 400 mbs … with the hyper-v virtual ethernet adapter inside the sandbox . Both the e2400 and the USB adapter are listed as 1GB links. The duplex is automatically negotiated by default in both. ipv6 is not the problem. I didn't find any program that could limit bandwidth that way … the only one was the killer device center, but I uninstalled it. I need help. It is a crazy situation. I really don't want to restart Windows 10 …
remember
the cable is good because I can get more than 700 on my other laptop
I tried to reset netsh, etc. unlucky
the speed inside vm is 450+ and outside is 145
I tried in safe mode, still 145.
The limiter is not the cause, disabling it I only gained -1 or -2 ms of ping with the same speed.
I really don't want to bomb the operating system.

## Multiplayer: what is a good engine with LAN support for low-end computers?

I want to make multiplayer LAN video games on my old low-end 32-bit Windows laptop. So far I found ORX and it's all they said it was. Unfortunately, it is not possible to make multiplayer games.

I am trying to find some engine to achieve this.

Of course, Unity is not an option, since it requires 64 bits. And some others require 4 GB of memory to run …

I've been doing video games in C, but I'm sure there is a better hidden option somewhere.

Thank you-

## networks: bridging LAN and WIFI using netplan does not work and kills AP

Hello everybody and thanks in advance!

I am trying to extend my local LAN network through WIFI and I would like to have all the devices on the same network. The configuration is as follows:

• DHCP / DNS server running inside the LAN
• Separate PC linked to the LAN, with WIFI capability (unfortunately it is not an option, have the DHCP / DNS server running on this machine)

As I am running Ubuntu 18.04, I am trying to use netplan to configure everything. Here is my configuration file:

network:
version: 2
renderer: NetworkManager
ethernets:
enp2s0:
dhcp4: no
gateway: 192.168.1.1
nameservers:
wifis:
wlp1s0:
access-points:
"MyWifi":
mode: ap
bridges:
br0:
dhcp4: yes
interfaces: (enp2s0, wlp1s0)


Now, running the two networks separately, that is, without the bridges section, everything works. With dnsmasq enabled, I can connect to the access point.

However, I can't seem to make the bridge work. Worse yet, as soon as the bridge is activated, access to the AP is no longer possible.

Does anyone have an idea, what am I missing?

## Enhanced LAN

I have been using an ASUS router for the past 4 years and it is working good But not great. When working in IT, I should use computers that give me more control over my network and inbound / outbound traffic. Finally I pulled the trigger bought in the Ubiquiti Unifi product line. To start, I have the security gateway, the POE switch and an AP. Finally I have everything configured, all my VLANs, networks and L2TP VPN configuration for remote access. I also have an IPS / IDS running on the …

## networks: network configuration, access via LAN or modem

I'm trying to do something unusual (for me; I'm just an advanced user of networks). I have a modem that has a static IP address assigned by Verizon. It is connected to a switch. I also have two PCs connected to that switch. The modem is configured to forward ports to a web server running on a PC. I would like to be able to connect to that web server either on the LAN (using the second PC) or from the Internet through the modem. LAN access is fine, but modem access does not work. I think I have double checked everything, and all IP addresses are fine. Is there a reason why a configuration like this would not work? Thank you!

ETA: I'm sure I'm missing some details here, but on the one hand, everything has a static IP address. The LAN addresses are 192.168.40.x.

## ssh: you can access the server from inside the LAN through an external IP, but you cannot connect remotely

Currently, I am trying to configure a Raspberry Pi server that can be accessed from the Internet. With the OpenSSH server running, I have sent a port to my Raspberry Pi. The problem is that, when I am inside the LAN, I can use SSH on my server using its internal IP 192.168.xxx.xxx and its external IP 112.xxx.xxx.xxx. However, when I try to connect from the internet, it does not connect.

I have performed some tests and if I change the port number on my SSH server, I can access it through its internal IP, but not its external IP, regardless of whether I am inside LAN or not. Also, when I tested the port verification sites and everyone seems to conclude that the forwarded port is closed, even with the OpenSSH service running on the correct port.

Not sure what to do with this. Although I have tried to find a solution, the most common problem associated with access to keywords, the public IP, the LAN seems to have to do with the inability to connect from inside the LAN and something related to a NAT fork, That does not seem to request my particular case.

If the ISP is blocking the port, I suppose I should not be able to connect to my server regardless of whether I am inside the LAN or not when I use its external IP. The only explanation I can think of is some kind of firewall that blocks all packets originating from outside the network.

The router in question is ZYXEL USG110. Any help would be greatly appreciated.

## nginx: SSL only works through LAN but not through WIFI

I am new here

I have a reverse proxy on my network that I can access from inside and outside without problems, but when I'm SSL enabled I can not access my website through WIFI in the network, only through LAN, through WIFI 5GHz or outside my network.

On the router I enabled fowarding of ports with 80 and 443.

There are no established iptables rules

Maybe the ISP router fails?

Here is my nginx conf

server {
server_name my.domain.com;
Location / {
proxy_pass http://my.domain.com/;
proxy_set_header Host $host; proxy_set_header X-Real-IP$ remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_http_version 1.1; Connection proxy_set_header ""; proxy_buffering out; client_max_body_size 0; proxy_read_timeout 36000s; proxy_redirect off; } listen to 443 ssl; # managed by Certbot ssl_certificate /etc/letsencrypt/live/my.domain.com/fullchain.pem; # managed by Certbot ssl_certificate_key /etc/letsencrypt/live/my.domain.com/privkey.pem; # managed by Certbot includes /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot } server { if ($ host = my.domain.com) {
returns 301 https: // $host$ request_uri;
} # handled by Certbot

server_name my.domain.com;
listen 80;
refund 404; # managed by Certbot
}



and a loop output from 2.4GHz WIFI within the network.
