That command did not work on my 11.1-RELEASE-p6 > system. I suspect the reason for it not working on your system is you do not have a host called gw, where as this person does. > > > root@apron:~ # route add -net 1.2.3.4 gw 127.0.0.1 > route: bad address: gw Try echo "1.2.3.4 gw" >>/etc/hosts and run the command again, you should now get an error about unreachable gateway. > Here's what worked for me. Just use route del with the same parameters I believe your correct, if the poster executes the orignal command with s/add/delete/ the right thing should just happen: route delete -net 61.177.172.137 gw 127.0.0.1 I believe if one looks at the man page for route: route [-n] command [-net | -host] destination gateway [netmask] [-fib number] you see that what happened here, after dns/hosts file translation was: route add -net 61.0.0.1 MY.GW.IP.HERE 127.0.0.1 The trailing 127.0.0.1 is interpretted as the netmask, and this is why you see 60.0.0.1&0x7f000001 as the route entry, 0x7f000001 is 127.0.0.1 in host order hex. > root@apron:~ # route add -net 1.2.3.4 127.0.0.1 > add net 1.2.3.4: gateway 127.0.0.1 > root@apron:~ # netstat -nr > Routing tables > > Internet: > Destination Gateway Flags Netif Expire > default 10.1.10.1 UGS bge0 > 1.2.3.4/32 127.0.0.1 UGS lo0 > 10.0.0.0/8 10.1.10.1 UGS bge0 > 10.1.10.0/24 link#1 U bge0 > 10.1.10.175 link#1 UHS lo0 > 127.0.0.1 link#2 UH lo0 > > Internet6: > Destination Gateway Flags > Netif Expire > ::/96 ::1 UGRS > lo0 > ::1 link#2 UH > lo0 > ::ffff:0.0.0.0/96 ::1 UGRS > lo0 > fe80::/10 ::1 UGRS > lo0 > fe80::%lo0/64 link#2 U > lo0 > fe80::1%lo0 link#2 UHS > lo0 > ff02::/16 ::1 UGRS > lo0 > > root@apron:~ # route del -net 1.2.3.4 127.0.0.1 > del net 1.2.3.4: gateway 127.0.0.1 > root@apron:~ # netstat -nr > Routing tables > > Internet: > Destination Gateway Flags Netif Expire > default 10.1.10.1 UGS bge0 > 10.0.0.0/8 10.1.10.1 UGS bge0 > 10.1.10.0/24 link#1 U bge0 > 10.1.10.175 link#1 UHS lo0 > 127.0.0.1 link#2 UH lo0 > > Internet6: > Destination Gateway Flags > Netif Expire > ::/96 ::1 UGRS > lo0 > ::1 link#2 UH > lo0 > ::ffff:0.0.0.0/96 ::1 UGRS > lo0 > fe80::/10 ::1 UGRS > lo0 > fe80::%lo0/64 link#2 U > lo0 > fe80::1%lo0 link#2 UHS > lo0 > ff02::/16 ::1 UGRS > lo0 > root@apron:~ # uname -a > FreeBSD apron.ad.nyingma.org 11.1-RELEASE-p6 FreeBSD 11.1-RELEASE-p6 #0 > r328506M: Sat Jan 27 23:09:57 PST 2018 > root@apron.ad.nyingma.org:/usr/obj/usr/src/sys/GENERIC > amd64 > _______________________________________________ > freebsd-net@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org" > > -- Rod Grimes rgrimes@freebsd.org
