Problem with the bwctl work on FreeBSD 11 #41

Closed 5minmoreplease closed 7 years ago

At startup bwctl can't determine the source address.

$ uname -a
FreeBSD node 11.0-RC1 FreeBSD 11.0-RC1 #0 r303979: Fri Aug 12 02:28:24 UTC 2016     root@releng2.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC  amd64
$ ./bwping -c "psum01.itep.ru:4823"
bwping: Couldn't figure out address to use to connect to psum01.itep.ru:4823

Trace from ./bwping -c "psum01.itep.ru:4823" truss.txt

Adding arguments -4 -B $local_address don't change anything.

Had the same problem with the bwctl tool. For me it helped to use the "-s"-Parameter. This parameter is also available for the bwping command. Try: ./bwping -c psum01.itep.ru -s 10.10.10.123 In this example 10.10.10.123 is the local IP address of the interface you want to use. At the "-c"-Parameter I am not sure if it is necessary to use the " and the port... try it out.

One other thing I had to do on machines with more then one interface is to setup a target-based Source-NAT, because I am going out on the external interface of the machine but want to use internal interface as sender... but this is a special installation, I think the first step with -s Parameter should help.
