lsdistcc - simple distcc server discovery
autodetects listening distcc servers either by looking in DNS for
hosts named according to a given
or by checking the host names given on the command line.
Hosts are considered good servers based solely on whether their name
fits the format and whether they are listening on the right port (and
optionally whether they respond when you send them a compile job).
Scans for hosts named according to
(default is "distcc%d"; see
and starting from 1, so hosts such as distcc1, distcc2, and so on.
Stops after 7 seconds or the first host name that does not resolve.
Prints the names of all such servers listening on distcc's port.
If a list of host names is given in the command line,
will only check those hosts.
Displays summary instructions
Output latency in milliseconds after each hostname
(not including DNS latency)
Print IP address rather than name
Append ,down to down hosts in host list
Set number of seconds to stop searching after 
Set number of milliseconds before retrying gethostbyname 
Set number of milliseconds before giving up on connect 
(0 to inhibit connect)
Set number of milliseconds before giving up on compile 
(0 to inhibit compile)
Set number of bits of address that must match first host found 
Set number of extra DNS requests to send 
Set number of missing DNS entries to tolerate 
Port to connect to 
Protocol version to use (1-3) 
Name of compiler to use [none]
Append DNS domain name to format
Scan for servers named distcc1, distcc2, ...
that provide a compiler named gcc-4.6
and include their latencies in the output:
$ lsdistcc -l -pgcc-4.6
Scan for a compiler named gcc-4.6 on the servers hosta, somehost, hostx, and hosty:
$ lsdistcc -pgcc-4.6 hosta somehost hostx hosty
To use the program in a build script, add the lines:
before the line that invokes make.
Or, in a Makefile, add the line:
export DISTCC_HOSTS = $(shell lsdistcc)
which automatically invokes lsdistcc if you set DISTCC_POTENTIAL_HOSTS.
The exit status is 0 if any servers were found, and 1 otherwise.
Uses 'for i=1... sprintf(format, i)' to construct names of servers,
stops after 7 seconds or at second server that doesn't resolve,
prints the names of all such servers listening on distcc's port.
Default format is distcc%d.
