System Requirements Linux

SafeSquid (version 4.1.1 and higher) for Linux requires an Intel Architecture Hardware with Linux Kernel 2.6 (or higher) and glibc 2.4 (or higher), based operating system, properly installed with preferably latest updates and patches.

Recommendations for Standard Installations

  • Use Linux Distributions that have a good support for Web Servers, Perl, PHP, Caching Name Servers, etc. because a variety of Log Analyzers are now available both as closed and open source, that you will surely want to use.
  • SafeSquid servers shouldn't be requiring x-windows, so basic hardening should be enough.
  • Sooner than later you would want to install Antivirus to scan content being transported via SafeSquid, ClamAV is free, so at least install it, unless you are sure you prefer to be secured by a commercial vendor. In such case, choose a vendor that offers ICAP based solution.
  • If you have a Microsoft Network, then sooner or later you will want authentication to work from ADS, and in any case if you are a large network you'll alternatively want user authentication done from LDAP or RADIUS, or something else, that's available, so definitely install PAM libraries. And maybe also Winbind, that joins your SafeSquid server to Windows Network.
  • RPMS are available for most of the software mentioned above, but quite a few are served as raw source codes, and must be compiled on your server. So it's always a good idea to install GCC & G++ on your SafeSquid Server.


System Libraries Provider Package Package Description bzip2-libs

Libraries for applications using bzip2

Description : Libraries for applications using the bzip2 compression format. e2fsprogs Utilities for managing the second extended (ext2) filesystem.

Description : The e2fsprogs package contains a number of utilities for creating, checking, modifying, and correcting any inconsistencies in second extended (ext2) filesystems. E2fsprogs contains e2fsck (used to repair filesystem inconsistencies after an unclean shutdown), mke2fs (used to initialize a partition to contain an empty ext2 filesystem), debugfs (used to examine the internal structure of a filesystem, to manually repair a corrupted filesystem, or to create test cases for e2fsck), tune2fs (used to modify filesystem parameters), and most of the other core ext2fs filesystem utilities.
glibc The GNU libc libraries.

Description : The glibc package contains standard libraries which are used by multiple programs on the system. In order to save disk space and memory, as well as to make upgrading easier, common system code is kept in one place and shared between programs. This particular package contains the most important sets of shared libraries: the standard C library and the standard math library. Without these two libraries, a Linux system will not function.
krb5-libs The shared libraries used by Kerberos 5.

Description : Kerberos is a network authentication system. The krb5-libs package contains the shared libraries needed by Kerberos 5. If you are using Kerberos, you need to install this package. libgcc GNU C library

Description : The libgcc1 package contains GCC shared libraries for gcc 3.4
