![]() ![]() ![]() To make this easy for students, we used one address (e.g., ) that students could ssh to, which would load-balance the ssh connections across our various lab computers. The former now especially relevant as our institution had halved the number of students on campus and eliminated in person computer lab access as a response to the pandemic. This is an especially popular feature for students who either (1) aren’t on campus or (2) want to work from elsewhere on campus. To access the lab computers remotely, students ssh in. These 100 or so lab computers are spread out over the various lab locations on campus–all of which that run linux. The Swarthmore CS department maintains our own servers ( i.e., dns, web, email, ldap, etc) and lab computers. This page is a modified mirror of Jeff’s page that describes our setup. I completed this project in partnership with my CS Department’s wonderful Sysadmin Jeff Knerr. Username and Password - user authentication.Īppear as Web Browser - if checked, Proxifier emulates browser’s environment (some firewalls deny all requests that do not come from a browser).One of the many things I did last summer (2020) was set up a up HAProxy as a load-balancer for my CS department’s incoming ssh connections. SOCKS 4A extension - allows remote name resolving (“DNS through proxy” feature) for SOCKS v4 proxy. User ID - used for the purposes of authentication. The options available depend on the proxy server protocol. Please make sure that you have read and understood the HTTP proxy servers topic before using this option! You can enable this protocol at Profile->Advanced on HTTP Proxy tab. Unfortunately, such proxies can only be used for HTTP connections. HTTP - the most common type of proxy servers.You can also check the proxy with the Proxy Checker tool (Windows only). If an HTTP proxy works properly in the browser but fails in Proxifier, it most likely means that SSL support is unavailable. Many HTTP proxy servers do not support SSL tunneling therefore, they cannot be used as HTTPS. HTTP proxy with SSL tunnel support is also known as: Technical documentation can be found at: HTTPS - HTTP proxy with SSL support for arbitrary ports.Technical documentation can be found at: and SOCKS version 5 - has more features than version 4 and supports authentication.SOCKS version 4(A) - a widely used proxy server protocol that does not support authentication.Proxifier supports four types of protocols: The port number to connect to the proxy server (usually 1080, 80, 8080, 3128, etc.) The address of the proxy server can be a hostname or IPv4/IPv6 address. To add a proxy server, click the Add button, which will open the form where you can specify the details of the proxy server: You can sort the list by address, port and type (protocol). The order of the proxy servers in the list is not relevant. If several proxy servers are specified, you can create a proxy chain. This will open a dialog window where you can add, edit or remove proxy servers and proxy chains used by Proxifier. Your applications should then be configured to connect “directly” to the Internet (rather than through proxies). If you were using proxies before you installed Proxifier you should disable any built-in proxy settings. To add a proxy server, click either Proxy Servers in the Profile menu or the corresponding item on the toolbar: ![]()
