panic.polar.on.ca, a FreeBSD 2.2.6 machine, can't ping itself. When
squid is installed it fails to reach the web sites that are associated with
the aliased IP addresses. I've had the same problem with 2.2.4 and 2.2.5.
I thought it was a bug, I guess it is a feature.
IP address of machine is .101. Alias address are shown below. Alias
entries are created in rc.conf like this:
ifconfig_ep0_alias0="inet 199.212.22.99 netmask 255.255.255.192"
ifconfig_ep0_alias1="inet 199.212.22.102 netmask 255.255.255.192"
ifconfig_ep0_alias2="inet 199.212.22.106 netmask 255.255.255.192"
ifconfig_ep0_alias3="inet 199.212.22.107 netmask 255.255.255.192"
ifconfig_ep0_alias4="inet 199.212.22.108 netmask 255.255.255.192"
How can I make aliases do what I expect? Under OS/2 I can ping
aliases created with "ifconfig ... alias." Do I need another parameter?
Do I need to create specific arp entries? How do I do that?
