Does anybody know if there is an equivalent tool to tcpkill for killing TCP connections that travel over Infiniband? At the moment, when I use an infiniband interface, tcpkill complains:

# tcpkill -i ib0 port 12345
tcpkill: unsupported datalink type
tcpkill: couldn't determine link layer offset

Thanks in advance

tcpkill comes from dsniff package. In the source I have found the problem in pcaputil.c. Adding support for DLT_IPOIB, DLT_IPV4 and DLT_IPV6 and correct offset is likely to fix tcpkill regarding IPoIB. – Yann Droneaud Feb 15 '12 at 16:49
BTW, this is not InfiniBand over IP (iWRAP), but IP over InfiniBand (IPoIB). – Yann Droneaud Feb 15 '12 at 16:51
In fact it is likely DLT_LINUX_SLL given tcpdump output. – Yann Droneaud Feb 15 '12 at 17:07
@ydroneaud yes, it was IPoIB (thanks Roland for the correction) – Luca Martini Feb 16 '12 at 11:39
it's 2020 and still have the same problem. Any alternative commands/tool at least? – Ioannis Kourouklides Oct 10 '20 at 11:01
