TELNET-PROBE(1)TELNET-PROBE(1)NAMEtelnet-probe - lightweight telnet-like port probe
SYNOPSIS
$PCP_BINADM_DIR/telnet-probe [-v] host port
DESCRIPTIONtelnet-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 tel‐
net connection. Next, telnet-probe will read from the telnet connec‐
tion 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.
