| What about proxy authentication via LDAP? SSL options? Are these enabled by | default? | | Along the lines of the PHP, Apache feature/module comparison tables (that were | posted earlier in this mailing list), it would be useful to see a feature list | of Squid comparing the other OS distributions vs the one that would be part of SFW.
============================================ Here is a comparison with various distributions. All except coolstack are on squid 2.6.STABLE1X cool stack on squid 2.5. I will add more soon. Notes: . is default, x is set, - not set, ? tentative -p is may negatively affect performance +p is may positively affect performance +c adds dependencies ============================================ CoolStack FreeBSD 6.1 FedoraRPM Win32 SUNWsquid --enable-dlmalloc - - - - - --enable-gnuregex - - - - - --enable-carp - - - - x --with-aufs-threads 8 - - - x --with-aio - - - - - --enable-storeio aufs x - x x x coss x - x x x diskd x x x - x ufs x x x x x null x x x x x --enable-removal-policies heap x x x x x lru x x x x x --enable-icmp - - - - - --enable-delay-pools x - x x x --enable-useragent-log x - x x ?

Unless you have reason to use this option, you should not enable it. This library file is usually only required on Windows and very old Unix boxes which do not have their own regex library built in. --disable-carp Disable CARP support --enable-async-io=N_THREADS Shorthand for --with-aufs-threads=N_THREADS --with-pthreads --enable-storeio=ufs,aufs --enable-storeio="list of modules" Build support for the list of store I/O modules. The default is only to build the "ufs" module. See src/fs for a list of available modules, or Programmers Guide section <not yet written> for details on how to build your custom store module --enable-heap-replacement Backwards compatibility option. Please use the new --enable-removal-policies directive instead. --enable-removal-policies="list of policies" Build support for the list of removal policies. The default is only to build the "lru" module. See src/repl for a list of available modules, or Programmers Guide section 9.9 for details on how to build your custom policy --enable-icmp Enable ICMP pinging (keep track of gateways) --enable-delay-pools Enable delay pools to limit bandwidth usage --enable-useragent-log Enable logging of User-Agent header --enable-referer-log Enable logging of Referer header --disable-wccp Disable Web Cache Coordination V1 Protocol --disable-wccpv2 Disable Web Cache Coordination V2 Protocol --enable-kill-parent-hack Kill parent on shutdown --enable-forward-log Enable experimental forward_log directive --enable-multicast-miss Enable experimental multicast notification of cachemisses --enable-snmp Enable SNMP monitoring --enable-cachemgr-hostname=hostname Make cachemgr.cgi default to this host --enable-arp-acl Enable use of ARP ACL lists (ether address) --enable-htcp Enable HTCP protocol --enable-ssl Enable ssl gatewaying support using OpenSSL --enable-forw-via-db Enable Forw/Via database --enable-cache-digests Use Cache Digests see http://www.squid-cache.org/FAQ/FAQ-16.html --enable-coss-aio-ops Enable COSS I/O with Posix AIO (default is aufs I/O) --enable-select Force the use of select support. Normally configure automatically selects a better alternative if available. --disable-select Disable select support, causing configure to fail if a better alternative is not available --enable-select-simple Force the use of select support (POSIX). Useful if your system only supports the bare minium POSIX select requirements without fds_bits. --enable-poll Force the use of poll even if automatic checks indicate poll may be broken on your plaform. --disable-poll Disable the use of poll. --enable-epoll Force the use of epoll even if automatic checks indicate epoll may not be supported. --disable-epoll Disable the use of epoll. --enable-kqueue Force the use of kqueue even if automatic checks indicate kqueue may not be supported. --disable-kqueue Disable kqueue support. --enable-devpoll Use Solaris /dev/poll instead of poll --disable-http-violations This allows you to remove code which is known to violate the HTTP protocol specification. --enable-ipf-transparent Enable Transparent Proxy support for systems using IP-Filter network address redirection. --enable-pf-transparent Enable Transparent Proxy support for systems using PF network address redirection. --enable-linux-netfilter Enable Transparent Proxy support for Linux 2.4 and later --enable-large-cache-files Enable support for large cache files (>2GB). WARNING: on-disk cache format is changed by this option --enable-linux-tproxy Enable real Transparent Proxy support for Netfilter TPROXY. --enable-leakfinder Enable Leak Finding code. Enabling this alone does nothing; you also have to modify the source code to use the leak finding functions. Probably Useful for hackers only. --disable-ident-lookups This allows you to remove code that performs Ident (RFC 931) lookups. --disable-internal-dns This prevents Squid from directly sending and receiving DNS messages, and instead enables the old external 'dnsserver' processes. --enable-truncate This uses truncate() instead of unlink() when removing cache files. Truncate gives a little performance improvement, but may cause problems when used with async I/O. Truncate uses more filesystem inodes than unlink.. --enable-default-hostsfile=path Select default location for hosts file. See hosts_file directive in squid.conf for details --enable-win32-service Compile Squid as a WIN32 Service Works only on Windows NT and Windows 2000 Platforms. --enable-auth="list of auth scheme modules" Build support for the list of authentication schemes. The default is to build support for the Basic scheme. See src/auth for a list of available modules, or Programmers Guide section authentication schemes for details on how to build your custom auth scheme module --enable-basic-auth-helpers="list of helpers" This option selects which basic scheme proxy_auth helpers to build and install as part of the normal build process. For a list of available helpers see the helpers/basic_auth directory. --enable-ntlm-auth-helpers="list of helpers" This option selects which proxy_auth ntlm helpers to build and install as part of the normal build process. For a list of available helpers see the helpers/ntlm_auth directory. --enable-digest-auth-helpers="list of helpers" This option selects which digest scheme proxy_auth helpers to build and install as part of the normal build process. For a list of available helpers see the helpers/digest_auth directory. --enable-negotiate-auth-helpers="list of helpers" This option selects which negotiate scheme authentication helpers to build and install as part of the normal build process. For a list of available helpers see the helpers/negotiate_auth directory. --enable-ntlm-fail-open Enable NTLM fail open, where a helper that fails one of the Authentication steps can allow squid to still authenticate the user. --enable-external-acl-helpers="list of helpers" This option selects which external_acl helpers to build and install as part of the normal build process. For a list of available helpers see the helpers/external_acl directory. --disable-unlinkd Do not use unlinkd --enable-stacktraces Enable automatic call backtrace on fatal errors --enable-x-accelerator-vary Enable support for the X-Accelerator-Vary HTTP header. Can be used to indicate variance within an accelerator setup. Typically used together with other code that adds custom HTTP headers to the requests. --enable-follow-x-forwarded-for Enable support for following the X-Forwarded-For HTTP header to try to find the IP address of the original or indirect client when a request has been forwarded through other proxies. Optional Packages: --with-aufs-threads=N_THREADS Tune the number of worker threads for the aufs object store. --with-pthreads Use POSIX Threads --with-aio Use POSIX AIO --with-openssl=prefix --with-coss-membuf-size COSS membuf size (default 1048576 bytes) --with-large-files Enable support for large files (logs etc). rahul -- 1. e4 _
