 TWiki Web > TWikiSystemRequirements| Resource | Required Server Environment * | 
|---|---|
| Perl | 5.005_03 or higher (5.6.1 recommended, 5.8.x does work in most cases, but see TWiki:Codev.IssuesWithPerl5dot8) | 
| Non-standard Perl modules | • Unix: Net::SMTP(orsendmail)• Windows: Net::SMTP,MIME::Base64,Digest::SHA1• Internationalisation: Unicode::MapUTF8(only for non-ISO-8859-1 sites using TWiki:Codev.EncodeURLsWithUTF8 with Perl 5.6 or lower) | 
| RCS | 5.7 or higher (including GNU diff)Optional, but the all-Perl RCS replacement is not currently recommended for live sites - see TWiki:Codev.RcsLite | 
| GNU diff | GNU diff2.7 or higher is required when not using the all-Perl RcsLite.Install on PATH if not included with RCS (check version with diff -v)Must be the version used by RCS, to avoid problems with binary attachments - RCS may have hard-coded path to diff | 
| Other external programs | fgrep, egrep | 
| Cron/scheduler | • Unix: cron• Windows: cronequivalents | 
| Web server | Apache 1.3 is well supported; Apache 2.0 is not recommended yet (see TWiki:Codev.IssuesWithApache2dot0). For other servers, CGI support, authentication, extended path info required; also, the registerscript is likely to need significant changes |
