If you need a powerful cross-platform proxy server, you will probably not find anything better than Squid. It supports traffic filtering and caching. As new versions are released, more and more tools are added. The latest version already has ssl filtering, new filtering and caching options. Often users ask how to find out the version of Squid installed in the system. It is quite easy to do, and a professional is unlikely to encounter difficulties, which cannot be said about beginners.
Easy way to find out the version
There is no simpler way to find out the version than typing a command:
$ squid –v
Alternatively:
$ squid3 –v
This is the command for versions above 3.x. Already here the compilation flags, compiler version, and distribution version are collected. The program name and version are displayed at the very top.
You can also find out the version of Squid using the package manager. In most cases, the package version is the same as the software version. Therefore, it is easy enough to see the package information. This is done as follows:
$ dpkg -s squid
This is a simple instruction that will certainly come in handy for beginners. There is nothing complicated in these operations.
