Configure ping reply time

rabeea · 01-17-2005, 03:02 AM

hi All,

My machine (Windows 2000 Pro)works in a manner that if i try ping other machines in the network it shows me the ping reply upto 1400ms and then it shows request timed out. Now wat i wanna do is that even if ping reply time is above 1400ms it still gives me the response.In other words i want to rest the ping reply time variable in my machine. Guide me to do so.
Waiting for an earliest response.
Thnx

You might want to look at the help options for ping:
C:\>ping /?

Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]
[-r count] [-s count] [[-j host-list] | [-k host-list]]
[-w timeout] target_name

Options:
-t Ping the specified host until stopped.
To see statistics and continue - type Control-Break;
To stop - type Control-C.
-a Resolve addresses to hostnames.
-n count Number of echo requests to send.
-l size Send buffer size.
-f Set Don't Fragment flag in packet.
-i TTL Time To Live.
-v TOS Type Of Service.
-r count Record route for count hops.
-s count Timestamp for count hops.
-j host-list Loose source route along host-list.
-k host-list Strict source route along host-list.
-w timeout Timeout in milliseconds to wait for each reply.

So you would probably want to do something like 'ping -w 3000 Target_name'

so it looks like you need to use the -i switch.

If I remember correctly...
The -i (TTL) refers to the number of routers that you will go through before giving up. I believe default is 256 as you go through a router this will decrease and when it hits 0 it will not try anymore and give you back a "TTL expired in transit." message.
Example time!
ping -i 2 google.com returns this:

hi All,

thnx for taking out time to reply. Well these options might help me work but still i dont want to mention these switches(-w,-i) again and again and i want to configure it in such a way that once configures permanently it itself works and makes the maximum ping time upto 3000ms.

Looking forward towards more support
Thnx

Code:

H:\>set/?
Displays, sets, or removes cmd.exe environment variables.

SET [variable=[string]]

  variable  Specifies the environment-variable name.
  string    Specifies a series of characters to assign to the variable.

Type SET without parameters to display the current environment variables.

If Command Extensions are enabled SET changes as follows:

SET command invoked with just a variable name, no equal sign or value
will display the value of all variables whose prefix matches the name
given to the SET command.  For example:

    SET P

would display all variables that begin with the letter 'P'

SET command will set the ERRORLEVEL to 1 if the variable name is not
found in the current environment.

SET command will not allow an equal sign to be part of the name of
Press any key to continue . . .

hi,

Yeah i did tried that as well. But all i could find is that ping is not an environment variable which could be set. Yes we can set parameters for CMD but it messes with the syntax in which i write.
Still looking for a possible solution.

thnx
