My guess here is that if you excluded IPv6 support from the kernel that would explain the failure.<o:p></o:p></span></p>

<p class="MsoNormal">it looks like i found the culprit<br>
<br>
when running ibacm out of the box on rhel 7.4 the ibacm.log shows<br>
<br>
acm_if_iter_sys: ioctl ifconf error -1<br>
<br>
if i change the line<br>
<br>
s = socket(AF_INET6, SOCK_DGRAM, 0);<br>
<br>
to<br>
<br>
s = socket(AF_INET, SOCK_DGRAM, 0);<br>
<br>
as Hal suggested and start the ibacm daemon i acm correctly bind to be<br>
ipoib addresses and interfaces. my initial report of this change not<br>
being effective was a miss communication in that i though it related<br>
to the client and not the service process<br>
<br>
i can then run<br>
<br>
ib_acme -f i -s 172.22.64.96 -d 172.22.64.96 -S 172.22.64.96 -v V<br>
<br>
and get back valid data<br>
<br>
ib_acme -d <hostname> still doesn't work, but that might be internal<br>
we don't currently have reverse/forward entries for our ipoib<br>
interfaces, i'm still looking into it<o:p></o:p></p>
