How to use MacPorts (rsync) through a SOCKS5 proxy

mac-osxPROXYrsyncsocks

MacPorts relies on rsync to do its job, and I rely on a SOCKS5 proxy to get full access to internet. How do I make rsync run all its queries through my proxy?

Alternatively to Sirex' answer, you can use nc(1) (netcat) to use the proxy.

Again, modify your ~/.ssh/config file:

Host server-prox
        Hostname www.server.com
        ProxyCommand /usr/bin/nc -x localhost:8080 %h %p

then run

rsync -e ssh server-prox:path/to/files

and rsync (or rather ssh) will automatically use the proxy command.

This assumes there is a SOCKS proxy running on localhost port 8080, which you can get with

ssh -D 8080 proxyserver.com

Personally I use

ssh -qfxND 8080 proxyserver.com

to set up a proxy tunnel, where -qfxN make the command run quietly in the background, see ssh(1).

Ssh – Use YaST through a SOCKS5 proxy

An "HTTP Proxy" and a "SOCKS5 Proxy" aren't the same thing. That's why YAST doesn't get it :)

A quick fix would be to install Squid or some other HTTP proxy on ip-of-box-with-internet-access , and then do something like ssh -L 12345:localhost:8080 user@ip-of-box-with-internet-access from the server. I do this all the time.

An example of a quick HTTP proxy would be micro proxy, but I haven't used that and thus can't give a recommendation. Squid isn't too bad to set up.

Configuring Ubuntu for Global SOCKS5 proxy

Each command has its own configuration parameters and/or configuration files to use proxy servers. For example, w3m recognizes the HTTP_PROXY environment variable and uses it as a proxy if defined. wget also has options related to proxy settings. apt-get can be configured also to use a proxy server (or better apt-cacher to cache your downloaded packages for future installs/upgrades).

At the very least, you can use iptables to redirect all you outgoing traffic to a specific proxy.

$ sudo iptables -t nat -A OUTPUT -p tcp --dport 80 -j DNAT --to-destination proxy_ip:proxy_port

Adding a rules such as the above is enough to transparently redirect all outgoing traffic to your proxy server. Of course, you can customize the rule according to your needs like forwarding other ports.
