Squid 2.5 for Windows NT 4.0/2000/XP/2003

Native port of Squid 2.5, with many NT service enhancement.

  • Current features:
    • Based on Squid 2.5 STABLE 5
    • Run as a native Windows NT Service
    • Currently supported build environments:
      • Microsoft Visual C++ 6.0 SP5
      • MSYS + MinGW
      • Cygwin
    • Multiple Squid service instances are allowed
    • Full Command line support when running as a service
    • Automatic Service restart after Squid failure on Windows 2000/XP/2003
    • Use PSAPI.DLL for full getrusage() emulation
    • Internal DNS looks in registry for configured DNS, resolv.conf no more needed
    • Multithreaded support for standard Squid external helpers or redirectors (pinger, unlinkd, dnsserver)
    • All squid -k switches (check, debug, interrupt, kill, parse, reconfigure, rotate, shutdown) works
    • Basic, NTLM and Digest Authentication schema
    • Native Windows NT Basic and NTLM Authenticators with NTLMv2 support
    • Cachemgr CGI interface supporting Microsoft IIS and Apache Web Server
    • SNMP
    • Revised awin32 async I/O
    • External ACL native WIN32 group helper for Windows Domains group membership check
    • OpenSSL Support at source level (no binary packages available)
    • Currently supported Windows platforms:
      • Windows NT 4.0 Workstation and Server SP4 and later
      • Windows 2000 Professional and Server
      • Windows XP Professional (Home Edition not tested)
      • Windows 2003 Server

    Current ChangeLog

    Some special builds are available on Squid download Page

  • Licensing
  • Install:
    • If You are upgrading from SquidNT 2.3, please uninstall the old service and merge your old squid.conf in the new squid.conf configuration file. Don't forget to take a look about squid.conf changes on Squid 2.4 and Squid 2.5 pages
    • Extract the binary archive in the desired directory (default c:\squid)
    • Read the CompileOptions.txt file
    • Copy squid.conf.default as squid.conf and mime.conf.default as mime.conf
    • Edit the squid.conf and change if needed the c:/squid path (use path with '/' char, NOT '\')
    • Manually create ALL the directories specified in squid.conf, except the contents of the cache directory
    • Starting with PRE9 revision, squid.exe was moved from bin to sbin directory.
      Please remove and reinstall SquidNT service to reflect the changes.
    • squid -i [-f configfile] [-n servicename] (installs the servicename Squid service using the configfile configuration file, default configfile is "c:/squid/etc/squid.conf", default servicename is "SquidNT")
    • squid -z [-f configfile] (creates the cache directories)
    • squid -O servicecommandline [-n servicename] (Set in Windows Registry the Squid servicename service command line)

  • Uninstall:
    • squid -r [-n servicename] (removes the servicename Squid service)

  • Usage:
      Service mode:
    • Start: Control Panel/Services: choose "Start" for the "SquidNT" service.
    • Stop: Control Panel/Services: choose "Stop" for the "SquidNT" service.
    • squid -h Print help message.
    • squid -n servicename [-f configfile] -k reconfigure | rotate | shutdown | interrupt | kill | debug | check
      Send signal to running copy and exit.
    • squid -O servicecommandline [-n servicename] Set Windows Service Command line options in Registry.
    • squid -v Print version.

      The rest of the (original) cmdline switches when running as a Service must be used once with the -O switch. If multiple service command line options must be specified, use quote.

      Don't use the "Start parameters" in the Windows 2000/XP/2003 Service applet: they are specific to Windows services functionality and Squid is not designed for understand they.

      Example: 
      squid -O "-D -a 8080" -n squidsvc
      Don't forget to take a look on Squid documentation on http://www.squid-cache.org/

      This Squid build can support multiple Squid service instances running from the same executable, so the service name MUST be ALWAYS specified when using all -k, -O commands even running only one instance.

      Every instance must have a different service name, use different TCP ports, use different logs and cache directory and use a different configuration file.
      So, when installing the service, if don't using the default settings (c:/squid,SquidNT Service Name), the service name and the associated config file MUST be specified.
      The same when removing or running squid -k or -O commands.

      Command Line mode:
    • All Squid cmdline switches are available, except the -N (no daemon mode)

  • Compiling source code:
    • Microsoft build environment:
      • Microsoft Visual C++ 6.0 Service Pack 5
      • Microsoft latest Core SDK
      • Native CVS, gawk, perl,sed and patch for NT
    • MinGW environment:
      • MSYS 1.0.9 or later
      • MinGW 3.1.0 or later
      • Windows API 2.4.0 or later
      • MSYS Developer Tool Kit 1.0.1 or later
    • Build environments configuration
    • How obtain the sources:
    • Build using Microsoft Visual Studio:
      • Check ASCII format of all project files, must be DOS (CR+LF)
      • Check paths on all project files
      • Verify the Squid options defined in autoconf.h
      • Check default parameters on squid_mswin.mak file
      • Check settings on Install files project
    • Build using MinGW:
      • From MSYS prompt run: 
        ./configure --prefix=c:/squid --enable-win32-service --enable-default-hostsfile=none
        make
      • For other configure options see Squid FAQ

  • Compatibility Notes:
    • It's recommended to use / char in Squid paths instead of \
    • Paths with spaces (like C:\Programs Files\Squid) are NOT supported by Squid
    • When using ACL like acl aclname acltype "file" the file must be in DOS text format (CR+LF) and the full Windows path must be specified, for example: 
      acl blocklist url_regex -i "c:/squid/etc/blocked1.txt"
    • The WIN32 equivalent of /dev/null is NUL
    • Squid doesn't know how to run external helpers based on scripts, like .bat, .cmd, .vbs, .pl, etc. So in squid.conf the interpreter path must be always specified, for example: 
      redirect_program c:/perl/bin/perl.exe c:/squid/libexec/redir.pl
      redirect_program c:/winnt/system32/cmd.exe /C c:/squid/libexec/redir.cmd
    • When Squid runs in command line mode, the launching user account must have administrative privilege on the system
    • "Start parameters" in the Windows 2000/XP/2003 Service applet cannot be used

  • Known Limitations:
    • Squid features not operational:
      DISKD: needs to be ported - Volunteers are welcome
      WCCP: cannot work because GRE support on Windows is missing - Volunteers are welcome
      Transparent Proxy: missing Windows non commercial interception driver
    • Some code sections can make blocking calls
    • Some external helpers may not work
    • File Descriptors number hard-limited to 2048
      At this time Windows is a platform partially supported from Squid Community.
      For general Squid configuration ask always on squid-users mailing list.

      No warranties of any kind. No time for support, sorry. Use at your own risk.
