I have a problem encoding the OPENVPN config file. I would be grateful if you could advise me.
when we use openvpn via one proxy we can use this command:
http-proxy PROXY-IP PROXY-PORT auto
USERNAME
PASSWORD
How to change the above code so that when the connection to the first proxy server is established, it is established to the second proxy server (and to the end in a certain number) and finally to the main vpn server?
thank you for your attention

Is there any way for me to connect to a VPN without having it use my DNS? My internet provider where im connected can only use the DNS to connect to a separate server, which then connects to the internet as the router only interacts with that server, so if I change my DNS, my connection instantly stops working.
Is there any service that connects to a server without DNS as a VPN, or even some way to set up a proxy to go to another server after it interacts with my DNS?
Tried Changing DNS, no connection using cloudflare or google DNS servers (1.1.1.1, 8.8.8.8), Hotspot Shield VPN wouldn't connect, VPN from my home network wouldn't connect.
So, your ISP allows DNS traffic only to its server. And you want to by-pass this limitation.
Solution 1: SSH Proxy
ssh -D 5000 user#host
Now, you can set your applications to use proxy on socks5://localhost:5000
You must set "Proxy DNS on socks5"
This proxy goes throught the SSH server
Of course you need SSH server somewhere to connect to.
Solution 2: DNS over HTTPS
https://en.wikipedia.org/wiki/DNS_over_HTTPS
https://manpages.ubuntu.com/manpages/bionic/man1/dnss.1.html
It should work because your DNS packages go as HTTPS packages.
Solution 3: VPN or other services like nordvpn
It should work also since packages go encrypted to the VPN.
Actually, VPN should work without your ISP DNS as long as you connect to the VPN IP address instead the hostname.
Finally
Solution 2 seems to be the only one you are able to perform without external services.
Charles Web Debugging Proxy not connecting to localhost. It was working right after I installed, but all of a sudden get connection refused, when trying to connect to localhost. Other traffic is going through proxy ok. The web server and proxy ports are different. *.8888 proxy listening on all addresses.
Get the following error
Charles Error Report
Failed to connect to remote host
Charles failed to connect to the remote host. Check that your Internet
connection is ok and that the remote host is accessible. Maybe your
network uses a proxy server to access the Internet? You can configure
Charles to use an external proxy server in the External Proxy
Settings.
The actual exception reported was:
java.net.ConnectException: Connection refused Charles Proxy,
http://www.charlesproxy.com/
Did you use PHP Built-in server?
The FAQs of office document say:
Localhost traffic doesn't appear in Charles
Some systems are hard coded to not use proxies for localhost traffic, so when you connect to http://localhost/ it doesn't show up in Charles.
The workaround is to connect to http://localhost.charlesproxy.com/ instead. This points to the IP address 127.0.0.1, so it should work identically to localhost, but with the advantage that it will go through Charles. This will work whether or not Charles is running or you're using Charles. If you use a different port, such as 8080, just add that as you usually would, e.g. localhost.charlesproxy.com:8080.
You can also put anything in front of that domain, e.g. myapp.localhost.charlesproxy.com, which will also always resolve to 127.0.0.1.
Alternatively you can try adding a '.' after localhost, or replace localhost with the name of your machine, or use your local link IP address (eg. 192.168.1.2).
If Charles is running and you're using Charles as your proxy, you can also use local.charles as an alternative for localhost. Note that this only works when you're using Charles as your proxy, so the above approaches are preferred, unless you specifically want requests to fail if not using Charles.
If you use php built-in server use
php -S 127.0.0.1:8080 -t ./public
instead of
php -S localhost:8080 -t ./public
I have a VPN (pptpd) server configured and a client connected. In the same machine of VPN server, I have a proxy server (port 3128)(squid) running with authentication enabled. When I use the proxy in my firefox browser it works fine. However, when I conect my notebook to my VPN server I can't navigate using firefox + proxy. Just to remember Proxy server and VPN server running in same machine (a VPS). I'm using UFW firewall.
Is there some tips in configuration files (pptpd or squid) to get this problem fixed?
Best Regards!
use squid's access.log to make sure: squid doesn't receive requests from your notebook; check the routing availability between internal IP network of VPN server and proxy address, it must be accessible (pingable). you may use port address translation (PAT) as a simple fix.
A client has a web server that can only be accessed when on their network.
For example sake, let's say my login details are:
Server: example.com
User: user
password: password
for when I am on their company's internet. I use either Cyberduck or FileZilla to connect to their web server.
I'd much rather be able to connect remotely but I just have a lot of trouble setting this up. I have connected to the client's vpn, let's say vpn.example.com, and use Cisco AnyConnect to accomplish this.
Beyond this, my knowledge of VPN is limited. In an FTP client, is there anything I should be doing to ensure that it uses the VPN to connect to example.com rather than my home connection?
Thanks.

There two ways around this. I am assuming you are using Windows or a Mac since the AnyConnect client doesn't come in a Linux flavor.
Open a CMD/Terminal and type "route print" or "netstat -r" take note of where example.com is pointing to. Most likely the default route will catch it. In that case you want to add a route to have it go via the VPN interface for any traffic that goes to example.com (After doing this, once you disconnect from the VPN you will not be able to connect to example.com any more unless you connect to the VPN.)
The other way is to connect to the FTP using the local IP of the FTP once connected to the VPN.
As there is no Linux solution I will post my solution. I don't know much about the other side (vpn server side), so this solution might not fit your environment.
I'm using vpnc (installable via package manager on Ubuntu, other systems might work too). You can configure it with a .conf file, my values are
IPSec gateway <server address>
IPSec ID <gateway id>
IPSec secret <kind of group password>
Xauth username <your username>
Xauth password <you password>
If you are using UBUNTU
Install Open client for Cisco AnyConnect VPN from Ubuntu Software center, then use openconnect command.
My application (linux and windows) connects to oracle through OCI interface. Is it possible to connect to oracle through socks proxy? or some other similar proxy method? Simple ssh tunnel is not enough as I need to access multiple services (including oracle) through single port.
Edit: I have tried configuring the proxy as suggested in the answer, but it did not work. And I could not find anywhere information, that oracle can work through socks5 proxy.
I got the same issue to get solved. Anyway the solution above cannot work. You need to tell the client to just USE the proxy for connection initialization, but the target to connect to is supposed to be the oracle database server IP and port. Other forums read there is no such possibility via tnsnames.ora. But you're supposed to be able to achieve that using the Connection Manager. Haven't found out yet how to even download and install it though...
As I see Oracle doesn't support socks proxy.
To work around this for my self I did following:
Install proxifier www.freecap.ru
Start PL/SQL Developer from freecap
As I can see - this method not always work.
PL/SQL Developer was able to connect to database only on 3-4 try.
But after successful connect - it's seems stable enough for work.
Second option - is to use Java based tools like SQL Developer.
For Java there is system options for using SOCKS5 out of the box.
-DsocksProxyHost=localhost
-DsocksProxyPort=8081
there is official doc about SOCKS in java
Yes, this is possible. Your client tnsnames.ora file (or EZConnect string) should specify the proxy host as the database host, and the proxy listening port as the port. The SERVICE_NAME or SID is whatever the SQL*Net listener on the other side of the proxy is expecting.
[Edit]
If your proxy host is listening and forwarding on 1522, you should be able to:
telnet proxyhost 1522
and see:
Trying xx.xxx.xx.xxx...
Connected to proxyhost.domain.
