Hello all, I am trying to figure out why arping on one of my servers is unable to send more than one packet. When I am not using the verbose flag it will appear to "hang" and not exit until a ^C is given. With the verbose flag it just scrolls those pcap_dispatch errors down the terminal. (this is even the case when I specify -c 1) I don't know what 'arping: select=1 pcap_dispatch=0!' means. Could someone shed some light on this problem? Both systems are built with libnet11-1.1.2.1_1,1 and arping-2.05_2. Both are FreeBSD 6.2-RELEASE SMP I disabled the firewall completely during these tests Not working: [root@host /usr/home/user]# arping -v -c 4 xxx.xxx.90.200 This box: Interface: em0 IP: xxx.xxx.90.201 MAC address: 00:30:48:5b:1d:88 ARPING xxx.xxx.90.200 60 bytes from 00:11:09:2b:b5:28 (xxx.xxx.80.200): index=0 time=19.895 msec arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! arping: select=1 pcap_dispatch=0! ^C --- xxx.xxx.90.200 statistics --- 1 packets transmitted, 1 packets received, 0% unanswered [root@host /usr/home/user]# Working: [root@workinghost /usr/home/user]# arping -v -c 4 xxx.xxx.184.69 This box: Interface: fxp0 IP: xxx.xxx.236.156 MAC address: 00:0f:ea:47:52:f1 ARPING xxx.xxx.184.69 60 bytes from 00:30:48:57:5a:de (xxx.xxx.184.69): index=0 time=6.914 usec arping: select=1 pcap_dispatch=0! 60 bytes from 00:30:48:57:5a:de (xxx.xxx.184.69): index=1 time=5.007 usec arping: select=1 pcap_dispatch=0! 60 bytes from 00:30:48:57:5a:de (xxx.xxx.184.69): index=2 time=5.007 usec arping: select=1 pcap_dispatch=0! --- xxx.xxx.184.69 statistics --- 4 packets transmitted, 3 packets received, 25% unanswered Thanks.
