- This is the port for OS/2 platform of the Squid version 2.3.STABLE3
- HTTP caching proxy server.
-
- The first port was made by Peter Meerwald (pmeerw@cosy.sbg.ac.at,
- seawood@very.priv.at) for versions 1.1.0 and 1.1.15.
-
- All information about Squid is available on
- http://squid-cache.org/.
-
- System requirements:
- OS/2 Warp 3.0 with FP18, Warp 4.0 or Warp 4.5.
- TCP/IP v.4.0 or higher.
- HPFS or JFS partition.
- EMX 0.9d fix01 (or higher) runtime.
- ───────
-
- 32Mb or more of RAM, SCSI hard disk are highly recommended.
-
- Installation of binaries:
- Unzip the archive.
- Place GNUREGEX.DLL in any directory from LIBPATH.
- To simplify some manipulations with Squid edit squid.cmd and place
- it in any directory from PATH. To change the language for error
- messages, copy the contents of /language directory in
- etc/errors/errors.zip archive to etc/errors.
-
- Before starting it's necessary to customize the etc/squid.conf file.
- For brief information see QUICKSTART. OS/2 version understands
- SQUID_DIRECTORY environment variable as the default root of
- Squid tree. For example, place
- SET SQUID_DIRECTORY=d:\servers\squid
- in CONFIG.SYS or in the CMD file starting Squid and all default
- file names will be referred to this directory. Otherwise,
- start Squid with -f option for pointing to the actual squid.conf
- name.
-
- Other useful options:
- squid -h Print help message.
- squid -s Enable logging to syslog.
- The ported syslogd daemon is required.
-
- -k options are used to send a signal to the running process:
-
- squid -k shutdown |
- squid -k interrupt | Stop Squid.
- squid -k kill |
- squid -k reconfigure Restart with new configuration.
- squid -k rotate Close and rename log files.
-
- Squid -N option is ignoring because it is specific for UNIX.
- Under OS/2 you can use DETACH command for starting Squid in
- "daemon" mode.
- The binaries where compiled with -O3 -mpentium optimization
- and include only the standard features of Squid. To get more
- (not fully tested for OS/2) features (ICMP, SNMP, HTCP, Cache
- Digests et al) it's necessary to compile Squid from sources
- with last versions of gcc or pgcc after defining
- desirable options in include/autoconf.h. Also, recompilation
- is required for increasing of the open file descriptors limit
- from default (256) value (see
- http://squid-cache.org/Squid/FAQ/FAQ-11.html#filedescriptors).
- Both SQUID_MAXFD in include/autoconf.h and EMXOPT in src/Makefile
- must be changed. For recompilation it's sufficiently to start
- configos2.cmd without parameters and run make from lib and src
- directories.
-
- Cache Manager (cachemgr.exe) is the powerful tool for control Squid.
- This CGI-script must be placed in CGI-BIN directory of HTTP server.
- To start it go to http://localhost/cgi-bin/cachemgr.exe.
- The ACL for cache_object protocol must be properly defined in
- squid.conf.
-
- client.exe is the text mode client program that may be useful
- for testing purposes.
-
- dnsserver.exe (in old versions), unlinkd.exe and pinger.exe
- (for ICMP support) are the child processes of Squid using
- for time-consuming operations.
-
- ---------
-
- Known problems.
-
- 1. Squid uses the internal implementation for domain names
- resolving. The valid list of domain names server must be presented
- in %ETC%\resolv2 or in squid.conf.
- 2. For using Cache Manager with Lotus Domino Go web server,
- it's necessary to rename cachemgr.exe to nph-cachemgr.exe.
- 3. Netscape for OS/2 (2.02 and 4.04) sends the buggy request
- to Squid when trying to upload a file to ftp server.
- The full local file name is moving up to URL and request
- looks like
- PUT ftp://ftp.server.name/incoming/E:\LOCAL\PATH\FILENAME.ZIP.
- This problem is fixed in Netscape 4.61.
- 4. Some of default values in squid.conf are not optimal and must
- be changed.
- cache_dir Directory-Name Mbytes Level-1 Level-2
- To avoid the existence of thousands empty directories,
- Level-1 can be calculated as (Mbytes/200+1) instead of
- default value (16). For example:
- cache_dir d:/squid/cache 100 1 256
- These values are using as default when SQUID_DIRECTORY is defined.

- "replacement_policy" tag in squid.conf).
- - Fixed the bug (not my!), that caused "dirty" rebuilding
- after normal shutdown.
- - Improved ICMP support.
- - Reduced CPU usage in idle state.
-
-
- v. 2.2.stable5
-
- v. 2.2.stable4
-
- v. 2.2.stable3
-
- - Removed all patches around sscanf() problem, that's fixed in
- EMX 0.9d fix 01.
- - Included executable for NCSA authenticator.
-
- v. 2.2.stable1
-
- - Fixed the bug in SQUID_DIRECTORY implementation.
- - client -P option works now.
- - Some improvements in ICMP support.
- - Correct CPU time measurment (thanks to authors of OS2UNDOC info).
- - Child processes don't require the special initialization, so even
- REXX and Perl scripts can be used as redirectors and authenticators.
- - Some unofficial patches from http://hem.passagen.se/hno/squid/
- were included.
-
-
- v. 2.1.patch2
