# enslave(1)

start MandelSpawn computation servers

## NAME

enslave - start MandelSpawn computation servers

## SYNOPSIS

**enslave** \[ **-v** \] \[ **-n** \] \[ host \] ...

## DESCRIPTION

*Enslave* starts MandelSpawn computation servers (see  [*mslaved*(8)](/mslaved/8.md)) on hosts listed in the file *$HOME/.enslave*.  If a list of hostnames is given as  arguments, then servers are started only on those hosts.

The **-v** option causes *enslave* to print the rsh commands it executes to start the servers.  With the **-n** option, the commands are printed but not executed.

The file *.enslave* in the user's home directory contains the information necessary to start the computation servers.  It contains one line per host, each consisting of two or more whitespace-separated fields: the host name, the directory where the binaries of *mslaved* and *mslavedc* are stored, and any options that are to be passed to *mslavedc*.  The directory name may be relative to the user's home  directory on the remote host and should end with a slash.

In addition to the *.enslave* file, *enslave* uses information from the user's *.rhosts* file to determine a username for executing commands on each of the remote hosts.  Additional hostname-username  pairs for non-trusted hosts may be stored in *.rhosts* format in the  file *.rhostile*.

## FILES

$HOME/.enslave	control file\
 $HOME/.rhosts	hostname-username pairs for trusted hosts\
 $HOME/.rhostile	hostname-username pairs for non-trusted hosts

## SEE ALSO

xms(1), [bms(1)](/bms/1.md), [mslaved(8)](/mslaved/8.md), [mslavedc(8)](/mslavedc/8.md)

## BUGS

Forking off one rsh per host in parallel may be considered anti-social behaviour if the number of hosts is large.

Hostname aliases are not taken into account, so hostnames must be spelled identically in *.enslave*, *.mslaves*, *.rhosts*, and *.rhostile*.
