Before we had this in case of SYN retransmissions: (...) # ns4 MPTCP -> ns2 (10.0.1.2:10034 ) MPTCP (duration 1201ms) [ OK ] # ns4 MPTCP -> ns2 (dead:beef:1::2:10035) MPTCP (duration 1242ms) [ OK ] # ns4 MPTCP -> ns2 (10.0.2.1:10036 ) MPTCP ns2-60143c00-cDZWo4 SYNRX: MPTCP -> MPTCP: expect 11, got # 13 # (duration 6221ms) [ OK ] # ns4 MPTCP -> ns2 (dead:beef:2::1:10037) MPTCP (duration 1427ms) [ OK ] # ns4 MPTCP -> ns3 (10.0.2.2:10038 ) MPTCP (duration 881ms) [ OK ] (...) Now we have: (...) # ns4 MPTCP -> ns2 (10.0.1.2:10034 ) MPTCP (duration 1201ms) [ OK ] # ns4 MPTCP -> ns2 (dead:beef:1::2:10035) MPTCP (duration 1242ms) [ OK ] # ns4 MPTCP -> ns2 (10.0.2.1:10036 ) MPTCP (duration 6221ms) [ OK ] WARN: SYNRX: expect 11, got 13 # ns4 MPTCP -> ns2 (dead:beef:2::1:10037) MPTCP (duration 1427ms) [ OK ] # ns4 MPTCP -> ns3 (10.0.2.2:10038 ) MPTCP (duration 881ms) [ OK ] (...) So we put everything on one line, keep the durations and "OK" aligned and removed duplicated info to short the warning.
