SRV(8)SRV(8)NAMEsrv - start services
SYNOPSIS
lib/srv [ -n nsfile ] [ -v ] [ -s ]
DESCRIPTION
Srv starts listeners for local network services. It is now considered
obsolete: see svc(8), which replaces it using sh(1) and listen(1).
If the file /services/namespace exists, srv builds a new name space
using newns(2). The -n option may be used to supply a different file.
Srv then starts a listener for each service configured in /ser‐
vices/server/config.
The configuration file is a text file. Empty lines and lines beginning
# are comments, and ignored. Each non-comment line has at least four
fields: the server type, the service name, the network name on which to
announce the service (typically tcp or udp), and the path name of the
service command (module). Any further arguments are passed as argu‐
ments to that command.
Normally the server type field contains the letter S, and srv announces
the service on the network itself, listens for incoming calls, and on
each call invokes the command with any arguments given. The standard
input and output of the command are set to refer to the network connec‐
tion. If the server type field contains the letter M, however, srv
starts the given command once during its own initialisation, and leaves
the server to announce and manage its incoming calls. This is typi‐
cally used to start self-contained services such as bootp and tftpd.
The diagnostics from all servers will appear on the standard error of
srv itself.
For example, the default configuration file includes the following
lines:
S infsigner tcp /dis/auth/signer.dis
S infcsigner tcp /dis/auth/countersigner.dis
S inflogin tcp /dis/auth/logind.dis
S styx tcp /dis/lib/styxd.dis none clear sha md5 rc4 sha/rc4 md5/rc4
S rstyx tcp /dis/lib/rstyxd.dis none clear sha md5 rc4 sha/rc4 md5/rc4
S infdb tcp /dis/lib/dbsrv.dis none clear sha md5 rc4 sha/rc4 md5/rc4
S virgil udp /dis/lib/virgild.dis
The arguments to rstyxd and stxyd (see rstyxd(8)), and dbsrv(7) should
list the security algorithms supported by the server's ssl(3).

Each service should arguably start in a minimal name space.
