distccd
distcc server daemon for distributed compilation
TLDR
SYNOPSIS
distccd [options]
DESCRIPTION
distccd is the distcc server daemon that receives and processes compilation jobs from distcc clients on a network. It accepts preprocessed source code, compiles it using local compilers, and returns the object files to the requesting client.The daemon listens on TCP port 3632 by default and should be configured with access control to prevent unauthorized compilation requests. Security is implemented through IP address allowlists specified with the --allow option, as the protocol itself provides no authentication.distccd can limit the number of concurrent compilation jobs to prevent system overload. It logs to syslog by default but can be configured to write to specific log files. The daemon typically runs as a dedicated user with limited privileges for security.
