What Is CTM ?

  • "Code Through Mail" might best summarise it at 2018-12
  • Source Code (patches, delivery & update) Through Mail. CTM is ideal for receiving source code updates on slow, intermitent, or expensive tarrif (eg mobile/cell) internet connections. Used by & supported on FreeBSD (FreeBSD also supports & is supported by other access methods eg rsync); CTM could easily be used by other BSDs, Linuxes & beyond etc.
  • Etymology: "Cvs Tree Mirror" as named by code author phk@ in 1994-04-11
    ( CVS is a source code repository management system, as are eg SCCS, RCS, SVN/Subversion.
    BSD used SCCS, FreeBSD used CVS, although FreeBSD now (2018) uses SVN, CTM continues to deliver FreeBSD Code Through Mail.

Purpose Of

Traffic Limit

  • Please do not overload It is not a powerful mirror.
  • Please avoid heavy traffic during business hours in Germany Timezone +01:00. Time now
  • There is no point regularly ftp'ing latest deltas from here, as a purpose of CTM is to provide Push technology, so you should be receiving distribution updates by ctm-* mail lists. If you want to regular fetch (which is Pull technology, not push) then you should not be using CTM, but be using SVN or Rsync
    Just use archives if you fail to receive a delta for use by ctm_rmail.
