SOCKSIFY(1) General Commands Manual SOCKSIFY(1)


socksify - runtime socksification of selected programs


The shell script socksify is meant to aid in using socks with already compiled dynamic binaries. This works by setting the LD_PRELOAD environment variable to libdsocks. It will then attempt to wrap all networking-related system calls.

When used the script can socksify a program by simply prefixing the given program and its arguments with the socksify script, like in the example below.

$ socksify ftp


The socksify script, and the Dante socks library used by the socksify script, can interpret several environment variables.

Gives the name of the socks.conf file. Default is /etc/socks.conf, unless it was changed when compiling the Dante libsocks libraries.

Creating a socks.conf is the recommended way to use socksify, but socksify can also be used for most simple configurations without any socks.conf file, as long as the proxy server to use is set in one of the supported environment variables.

Enables debug logging. The value given should be a number, one or up, indicating the level of debugging provided.
This value controls where the client library sends logoutput. It can be either syslog, stdout, stderr, a filename, or a combination. The default is nowhere.
Use the value of SOCKS_USERNAME as the username when doing username authentication.
Use the value of SOCKS_PASSWORD as the password when doing username authentication. Not recommended as other users on the system might be able to see your password.
These variables allow the address of the server to be specified without using a socks.conf file. If a socks.conf-file is present, it is ignored if any of these variables are set.

The accepted format is <ipaddress>:<port>. If the SOCKS_SERVER value is set, it indicates the specified server supports all socks versions supported by Dante. If if either of the other two variables are used, they indicate the given socks server supports only the corresponding socks version, v4 or v5. Note that if the socks server requires any form of authentication, you need to use SOCKS5_SERVER, as v4 does not support authentication.

This variable can be used to specify the location of a HTTP proxy supporting the connect request. The format used to specify a HTTP proxy is http://<ipaddress>:<port>.
This variable can be used to specify the location of a UPNP enabled IGD router. There are three possible value for this variable: a full URL, the interface name the router is reachable via, or the value "broadcast" to search for the IGD on all appropriate interfaces.

proxy server to use are set, the Dante client will not parse the socks.conf file.

If this variable is set to "no", the client will not try to auto-add direct routes for all addresses on the LAN. The default is to add them.
If this variable is set, the client will not perform threadlocking. The default is for the client to attempt to figure out for itself whether the application to socksify needs threadlocking or not.
If this is set to "yes", the client will fallback to attempting a direct connection if the proxy route fails. The default is "no".
