After asking my question on several forum and search on Google, nothing good.
I have read something interesting about someone who want to use SSH as a coprocess and who fail with this:
girtby.net - The Other Kind of Reentrant
Finally, I think it's not possible to do by this way, because of SSH. After all I have read, SSH seem to be very boring to use in a script.
Like I want to communicate with network equipment like Cisco router, it's not possible tu use the system of public/private key so not possible to avoid the password prompt when I open the SSH sesssion.(Something is possible with
expect but if I can not use this it's better)
I want to do massive deploy of configuration on network equipment, about hundred, with Telnet it's ok but with SSH I don't know how I will do?
Idea? :)

I am wracking my brains over this. I am trying to use a Korn Shell script to execute an Oracle PL/SQL procedure, using the Oracle command line interface (sqlplus). The script starts sqlplus in a coprocess, and the two processes communicate using a two-way pipe. The bgnice option is off, so both... (8 Replies)

This is probably a simple one for the wise.

plink(1) PuTTY tool suite plink(1)
NAME
plink - PuTTY link, command line network connection tool
SYNOPSIS
plink [options] [user@]host [command]
DESCRIPTION
plink is a network connection tool supporting several protocols.
OPTIONS
The command-line options supported by plink are:
-V Show version information and exit.
-pgpfp Display the fingerprints of the PuTTY PGP Master Keys and exit, to aid in verifying new files released by the PuTTY team.
-v Show verbose messages.
-load session
Load settings from saved session.
-ssh Force use of SSH protocol (default).
-telnet
Force use of Telnet protocol.
-rlogin
Force use of rlogin protocol.
-raw Force raw mode.
-serial
Force serial mode.
-P port
Connect to port port.
-l user
Set remote username to user.
-m path
Read remote command(s) from local file path.
-batch Disable interactive prompts.
-pw password
Set remote password to password. CAUTION: this will likely make the password visible to other users of the local machine (via com-
mands such as `w').
-L [srcaddr:]srcport:desthost:destport
Set up a local port forwarding: listen on srcport (or srcaddr:srcport if specified), and forward any connections over the SSH con-
nection to the destination address desthost:destport. Only works in SSH.
-R [srcaddr:]srcport:desthost:destport
Set up a remote port forwarding: ask the SSH server to listen on srcport (or srcaddr:srcport if specified), and to forward any con-
nections back over the SSH connection where the client will pass them on to the destination address desthost:destport. Only works in
SSH.
-D [srcaddr:]srcport
Set up dynamic port forwarding. The client listens on srcport (or srcaddr:srcport if specified), and implements a SOCKS server. So
you can point SOCKS-aware applications at this port and they will automatically use the SSH connection to tunnel all their connec-
tions. Only works in SSH.
-X Enable X11 forwarding.
-x Disable X11 forwarding (default).
-A Enable agent forwarding.
-a Disable agent forwarding (default).
-t Enable pty allocation (default if a command is NOT specified).
-T Disable pty allocation (default if a command is specified).
-1 Force use of SSH protocol version 1.
-2 Force use of SSH protocol version 2.
-C Enable SSH compression.
-i path
Private key file for authentication.
-s Remote command is SSH subsystem (SSH-2 only).
-N Don't start a remote command or shell at all (SSH-2 only).
-sercfg configuration-string
Specify the configuration parameters for the serial port, in -serial mode. configuration-string should be a comma-separated list of
configuration parameters as follows:
o Any single digit from 5 to 9 sets the number of data bits.
o `1', `1.5' or `2' sets the number of stop bits.
o Any other numeric string is interpreted as a baud rate.
o A single lower-case letter specifies the parity: `n' for none, `o' for odd, `e' for even, `m' for mark and `s' for space.
o A single upper-case letter specifies the flow control: `N' for none, `X' for XON/XOFF, `R' for RTS/CTS and `D' for DSR/DTR.
