I wanted to test the "new" pf with support for hot-pluggable devices
and stumbled over the following issue:
## Version
[EMAIL PROTECTED] cat /etc/motd
OpenBSD 3.4-current (FLASHBANG) #20: Mon Jan 5 18:54:07 CET 2004
## pcmcia wireless NIC not plugged in :-)
[EMAIL PROTECTED] ifconfig wi0
wi0: no such interface
## Variant 1 - Everything fine here.
[EMAIL PROTECTED] cat pf1.conf
# pf1.conf
ext = "fxp0"
wi0 = "wi0"
pass in quick log on $ext inet proto icmp from any to ($ext) icmp-type 8 code 0
pass in quick log on $wi0 inet proto icmp from any to ($wi0) icmp-type 8 code 0
[EMAIL PROTECTED] pfctl -v -n -f pf1.conf
ext = "fxp0"
wi0 = "wi0"
pass in log quick on fxp0 inet proto icmp from any to (fxp0) icmp-type echoreq code 0
pass in log quick on wi0 inet proto icmp from any to (wi0) icmp-type echoreq code 0
## Variant 2 - I'm lazy and want to group interfaces. Hmm, doesn't work.
[EMAIL PROTECTED] cat pf2.conf
# pf2.conf
ext = "fxp0"
wi0 = "wi0"
allif = "{" $ext $wi0 "}"
pass in quick log on $allif inet proto icmp from any to ($allif) icmp-type 8 code 0
[EMAIL PROTECTED] pfctl -v -n -f pf2.conf
ext = "fxp0"
wi0 = "wi0"
allif = "{ fxp0 wi0 }"
pf2.conf:5: syntax error
## Variant 3 - Next try without ( ).
[EMAIL PROTECTED] cat pf3.conf
# pf3.conf
ext = "fxp0"
wi0 = "wi0"
allif = "{" $ext $wi0 "}"
pass in quick log on $allif inet proto icmp from any to $allif icmp-type 8 code 0
[EMAIL PROTECTED] pfctl -v -n -f pf3.conf
ext = "fxp0"
wi0 = "wi0"
allif = "{ fxp0 wi0 }"
no IP address found for wi0
pf3.conf:5: could not parse host specification
Sorry if this behaviour is described in the docs, maybe I just didn't
see it (Current is a fast moving target :-).
regards,
Oliver
