mtcp with openNetVM: Error in arp.conf: more entries than are specifed, #205

Closed SSam009 closed 6 years ago

SSam009 commented 6 years ago

Hello,

I am trying to run mTcp over openNetVM. Example application epserver failing with " Error in arp.conf: more entries than are specifed," error. Did I miss any configuration step?

Here is epserver output

[root@testhost example]# ./epserver -p /root -f epserver.conf -N 1

Please see if the total number of entries present in arp.conf match the ARP_ENTRY macro value. It looks like there is a mismatch.

@ajamshed Sorry, It's my mistake. ARP_ENTRY is not matching. I was able to run the example application.
