Config files distribution: copying a file to multiple hosts

Then you administer several dozens of boxes, similar data and configuration files are scattered on multiple hosts.  Slurping is a useful technique of getting all those files into a single location, editing them and then pushing them back. It is a simple Unix Configuration Management Tools technique that is often more productive then complex packages like puppet. It is very simple to implement with classic Unix tools such as  rdist or xargs+scp. And those methods works for "sysadmin hostile" flavors of Unix such as AIX and HP-UX, as in this case you can use Linux or Solaris as your head node for distribution.

Opposite to slurping operation is called file distribution. Here we need to upload one file or a list of files to specified list of hosts. It also has several variants.

You can upload only changes file preselecting them with find or other filter. You can also use make for this purpose.  You can also store files in configuration management system although is not very suitable for unix config file administration. But this way you get versioning as well.

NEWS CONTENTS

Old News ;-)

fileq

fileq transfers files from an incoming queue (directory) to a list of destinations. Destinations can only be directories on remote hosts. The respective transfers are performed using the sftp command line utility from the OpenSSH package. After a successful transfer to all destinations, the local queue (directory) is emptied. This tool can be very handy for automated distribution of files to different hosts using a cron job and public key based authentication in ssh connections.

[May 02, 2013] AFD

Freecode

AFD is a program to automatically distribute files either locally or to remote hosts. The files are distributed by using FTP or SMTP, and can be sent in parallel and with priority. It provides a GUI to monitor and control the distribution and extensive logging of all activities.

CVSup

Freecode

CVSup is a software package for transferring and updating collections of files across a network. It consists of a server called cvsupd and a client called cvsup. CVSup is faster (often by an order of magnitude) and more flexible than traditional network packages such as rdist and sup. In addition, CVSup has special knowledge of RCS files (as used by CVS). Software projects using CVSup to distribute their CVS repositories include FreeBSD, KDE, and (shortly) Postgres.

Autodist

Mar 14, 2008 | Freecode

Autodist is a source distribution management system that allows powerful mechanisms to define what is included in and excluded from a distribution and what license is used. It is especially targeted at large software projects that create multiple distributions from a source tree. Autodist supports distribution management in directory, file, and file content level, and automatic relicensing of a distribution.

Flamethrower

Flamethrower is a multicast file distribution system. It was originally created to add multicast install capabilities to SystemImager, but is designed as a stand-alone package. It works with entire directory heirarchies, rather than single files. It uses a server configuration file, which takes module entries similar to rsyncd.conf. It is an on-demand system; multicast of a module is initiated when a client connects, but it waits a predetermined period for other clients to connect before beginning.
