Assuming that PWR0 means the power is off and PWR1 means the power is on, and assuming that you want to mute if the power is on, I think you want something more like:
Obviously, this is untested (since I don't have an amp like this). If the amplifier has a command to terminate a command session, (something like exit or quit) you probably also want to add an echo to send that command to the amplifier in both of the above telnet scripts after the 2nd sleep.
Thanks! You are helping me allot!
When I add this code into the command line it gives me this:
This is just fine because it mutes the amp. This also works inside a bash script, making it executable and running it from the commandline.
When I add your script into the commandline it doesn't give me any errors, but it doesnt do anything else. It just goes back to the commandline. Maybe the connection is closed by foreign host maybe the problem. I also tried with or without the "" and this wasn't the solution. What am I doing wrong?

Hi Guys,
How do I write the script for the following
telnet 192.168.1.100 9002
if the result is less than 1 second. The script should say as port open
if the result takes more than 3 seconds. The script should display as port closed.
Thanks,

Hi all,
I would like to write a ad hoc shell script that would allow me to do some telnet tests to multiple IP's and ports at the same time . So, I want to determine which one is successful and which one fails. So, basically I would like the shell to spawn the telnet test and to break out of... (3 Replies)

Hello,
I wrote a script for doing telnet.However the requirement got changed and now I have to write a telnet script that will
1. Do the telnet from all the virtual ips in a box(Ex: x.x.x.x is the box ip, and x.x.x.1,x.x.x.2 etc are virtual ips associated with that box.)

iptos(4) Kernel Interfaces Manual iptos(4)NAME
iptos - Defines the IP Type Of Service (TOS) for FTP and Telnet
SYNOPSIS
/etc/iptos
DESCRIPTION
The /etc/iptos file configures the Type Of Service (TOS) of the Internet Protocol (IP) used by FTP and Telnet.
The TOS field in the Internet datagram is to specify how the datagram should be handled. It is a mechanism to allow control information to
have precedence over data.
Generally, protocols that are involved in direct interaction with a human should select low delay, while data transfers that involve large
blocks of data need high throughput. Finally, high reliability is most important for datagram-based Internet management functions.
In the Tru64 UNIX operating system, the ftp and telnet applications and the ftpd and telnetd daemons allow the configuring of TOS values.
These applications check to see if the /etc/iptos file exists; if the file exists, the applications obtain the TOS value from the file and
use that value to set the TOS field. If the /etc/iptos file does not exist, the applications default to the following TOS values recom-
mended by RFC1060: Low delay High throughput Low delay
Users who want to configure their own TOS values for the TOS field should provide the /etc/iptos file.
Note
Most IP routers do not differentiate based on TOS, and therefore providing values other than the default would have no affect. You
should not change the default values for FTP and Telnet.
Each entry should consist of a single line of the form:
Application Proto TOS-bits aliases
The entry fields contain the following information: The name of an application TOS entry. The protocol name for which the entry is appro-
priate. The TOS value to be set for the entry. A list of aliases that exist for the entry.
Items on an entry line are separated by any number of blanks, tabs, or combination of blanks and tabs. A number sign (#) indicates that
the rest of the line is a comment and is not interpreted by routines that search the file. Blank lines in the file are ignored.
Valid TOS entry names are ftp-control and ftp-data for FTP and telnet for Telnet.
The TOS value for the entry should be one of the following hexadecimal numbers, corresponding to TOS bits: Low delay High throughput High
reliability
If you need to disable the use of TOS bits, because you are having troubling communicating with a TCP/IP host that doe not conform entirely
with the IP specification, you can disable the TOS bits by using the the following settings in the /etc/iptos file:
# # Format of this file: # Application Proto TOS-bits aliases #
ftp-control tcp 0x0 ftp-data tcp 0x0 telnet tcp 0x0
EXAMPLES
The following example shows typical entries in the /etc/iptos file:
# # Format of this file: # Application Proto TOS-bits aliases #
ftp-control tcp 0x10 ftp-data tcp 0x08 telnet tcp 0x10
