How do I ping for 60 seconds in CMD?
ping www.google.com -t60
Doesn't works.
The command is working but not as you wanted since -t flag is for continuous ping unless stopped.
I think this ping feature you are looking for is available in Linux
It uses -i flag for interval from what I recall.

is there any way to set the system TCP KeepAliveTimeout in Windows 10?
In linux it is possible to do this thing by the following command:
echo 60 > /proc/sys/net/ipv4/tcp_keepalive_time
This command establishes a 60 second timeout for all connections.
I will appreciate any help
I tried creating the variable 'KeepAliveTime' in:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters
But it doesn't work.

The cluster system is constructed using the Perceus program. (scientific linuxs 6.9)
I installed condor in the vnfs file.
After this, when I make an ssh connection, I get a problem that ssh connection is disconnected after 10 minutes. The command is not recognized as shown below.
ssh was not disconnected before installing condor. However, we confirmed that pinging is done without loss.
how could fix this problem? Please suggest a solution

Can you go to this directory to edit ssh file
cd /etc/ssh/sshd_config
change
ClientAliveInterval 120
ClientAliveCountMax 720
This will make the server send the clients a “null packet” every 120 seconds and not disconnect them until the client have been inactive for 720 intervals (120 seconds * 720 = 86400 seconds = 24 hours).
I want to execute a .bat file 5 minutes after windows starts up. Unfortunately, windows task scheduler doesn't offer anything of the sort, only execute something right on start up. However, I need something to be 5 minutes after startup.
.bat file doesn't do much, just calls one separate .cmd file and passes a parameter. I've tried:
timeout /t 300 /nobreak
"C:\Documents and Settings\Administrator\Desktop\sikuli\runIDE.cmd" -r "C:\Documents and Settings\Administrator\Desktop\sikuli\SikuliXmlTestRunner.sikuli"
However, the runIDE.cmd gets called right away, regardless of the timeout.
You can give wait(300) command at the beginning in your sikuli script to achieve this.
XP doesn't have timeout command, use ping -n 300 localhost>nul or ping -n 1 -w 300000 localhost>nul.
I'm downloading huge sums of data at night and my PC in running through a UPS. Is there any way I can detect a power failure and command my PC to shut down automatically? Because I work at night, and there's no one to switch off the PC, it would be really helpful if anyone could help. Is it possible?
Thanks.
IMPORTANT: The scripts presented below will cause the system to shutdown whenever the network is down, so use them at your own risk!
A not so elegant way of doing what you want, if you have a network host (e.g. your router) that responds to ICMP echo requests and is not powered by the UPS (or at least the networking equipment is not powered by the UPS), would be to ping that host every few seconds and if it's down then shutdown the PC:
#!/bin/bash
while :
do
ping -c 1 -w 5 192.168.0.1 &> /dev/null
if [ $? -gt 0 ]; then
shutdown -hP now
break
fi
sleep 10s
done
You will have to change 192.168.0.1 to the IP address of the network host you want to ping.
You will also have to make the script executable with chmod +x <script_name> and place a call to it in /etc/rc.local (do not forget to append a & to make it run in the background) which will run the script as root on boot.
For completeness' sake, if the PC was running Windows XP one could use the following batch file:
:loop
ping -n 1 -w 5000 192.168.0.1
if not %ERRORLEVEL% == 0 (
shutdown -s
goto end
)
sleep 10
goto loop
:end
Note that the Windows batch file requires the sleep command which can be installed as part of the Windows Server 2003 Resource Kit Tools package (available as a free download from Microsoft's site)
If it's an APC and it has a data port you can use PowerChute. It's a java-based GUI (which could be a problem if this is your server) that does exactly what you are requesting.
I wrote a windows .bat script. To run a list of commands and then shut down the computer.
such as:
c:\someapplication.exe
c:\someapplication2.exe
Shutdown -s -t 0
Sometimes, "c:\someapplication.exe" freezes and do not respond. How can I setup timeout for my command "c:\someapplication.exe", so that after a certain amount of time, I want windows to force close the application and continue the rest of the commands?
You could use a combination of ping and taskkill to do this.
start c:\someapplication.exe
ping 127.0.0.1 -n seconds
taskkill /im someapplication.exe /f
start c:\someapplication2.exe
ping 127.0.0.1 -n seconds
taskkill /im someapplication2.exe /f
Shutdown -s -t 0 /f
Just replace seconds in the ping command with the number of seconds you want to wait before attempting to close the process (enough time so if it's still running it must have crashed). Then the rest of the app can continue until it is forced to shutdown.
if you may afford that all someapplications run in parallel try this
start someapplication
start someapplication2
wait n secons
shutdown
choose your value of n so that it does not proceed with shutdown while someapplications still run legit
or alternatively
start someapplication
wait n seconds
start someapplication2
wait m seconds
shutdown
for wait there are many solutions around, google some bat wait timeout
You can run your exe program and the shutdown command at once and put the timeout in shutdown options [-t].
To run multiple command at once, use "start" command ("start [yourProgram.exe]").
To do force shutdown use [-f] option.
good luck
