lsdistcc (1)

lsdistcc [OPTIONS] [FORMAT]

lsdistcc [OPTIONS] host1 ...

lsdistcc autodetects listening distcc servers either by looking in DNS for hosts named according to a given FORMAT, 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 FORMAT (default is "distcc%d"; see printf(3)) 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, lsdistcc will only check those hosts.

--help

Displays summary instructions

-l

Output latency in milliseconds after each hostname (not including DNS latency)

-n

Print IP address rather than name

-x

Append ,down to down hosts in host list

-tTIMEOUT

Set number of seconds to stop searching after [7]

-hHTIMEOUT

Set number of milliseconds before retrying gethostbyname [500]

-cCTIMEOUT

Set number of milliseconds before giving up on connect [900] (0 to inhibit connect)

-kKTIMEOUT

Set number of milliseconds before giving up on compile [1500] (0 to inhibit compile)

-mBITS

Set number of bits of address that must match first host found [0]

-oOVERLAP

Set number of extra DNS requests to send [1]

-gDNSGAP

Set number of missing DNS entries to tolerate [0]

-rPORT

Port to connect to [3632]

-PPROTOCOL

Protocol version to use (1-3) [1]

-pCOMPILER

Name of compiler to use [none]

-d

Append DNS domain name to format

-v

Verbose

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:

DISTCC_HOSTS=`lsdistcc`

export DISTCC_HOSTS

before the line that invokes make. Or, in a Makefile, add the line:

export DISTCC_HOSTS = $(shell lsdistcc)

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.
