Hey Amjad,

It’s a capital E, not lower case. You can also use “—no-endpoint”.

Cheers,

Hi,

I have run the command with -e flag but it shows following result:

[root@kahuku ~]# bwping -s 198.129.254.58 -e 180.211.191.42

Invalid -e: Syslog facility "180.211.191.42" unknown

In  my system, eflag shows "  -e   syslog facility to log to ".

I am using perfsonar  version '3.3.2".

thanks

Hello Amjad,

If the receiving side isn’t running bwctl, you can add the “-E” parameter to the bwping command, and it will run anyway.

Cheers,

Aaron

Now if I change the receive host in the above command with another IP where no bwctl running, get error:

[root@kahuku ~]# bwping -s 198.129.254.58 -c 180.211.191.42

bwping: Unable to connect to 180.211.191.42
