NAME

telnet-probe - lightweight telnet-like port probe

SYNOPSIS

$PCP_BINADM_DIR/telnet-probe [-v] host port

DESCRIPTION

telnet-probe allows the pmdashping(1) daemons to establish connections to arbitrary local and remote service-providing daemons so that response time and service availability information can be obtained.

The required host and port number arguments have the same meaning as their telnet(1) equivalents.

The -v option causes telnet-probe to be verbose while operating.

Once the telnet connection has been established, telnet-probe reads from stdin until end-of-file, and writes all the input data to the telnet connection. Next, telnet-probe will read from the telnet connection until end-of-file, discarding whatever data it receives. Then telnet-probe exits.

To operate successfully, the input passed via telnet-probe to the remote service must be sufficient to cause the remote service to close the connection when the last line of input has been processed, e.g. ending with ``quit'' when probing SMTP on port 25.

By default telnet-probe will not produce any output, unless there is an error in which case a diagnostic message can be displayed (in verbose mode only) and the exit status will be non-zero indicating a failure.

PCP ENVIRONMENT

Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configuration file, as described in pcp.conf(4).

DIAGNOSTICS

If telnet-probe succeeds, then 0 will be returned. If the attempt to establish a connection fails or is terminated, then a non-zero exit status is returned.

Ni Argo ? Ta morue marin
N'a bel liard. Rage t'écaille
Si sel lia cet égard raille
Banni rameur.. ô mât ô grain !

Cri à mat matelot amer :
"Case lien ultime ta bile
Ce célibat émit l'une île
Sacre ma tôle tam-tam air"

Cet artimon amirauté
Mal né - oh ! ce drakkar de l'âme
Mâle drakkar d'écho en lame
Tua, rima, n'omit raté

Pelé dur ce rameur calé
Dénia simoun et sirène
Je ne ris ténu ô misaine !
De la crue Mare Crudele

Plage. Le bac n'a l'abyssal
Ému ce lac rebat sa brume
Le mur basta ! berça l'écume
Las.. s'y balança bel égal
