Package: ifupdown
Version: 0.6.4-4.12
Severity: normal
Abstract:
"ifup -a" does not handle all interfaces defined with their
own "auto" stanza.
Workaround:
Add all interfaces into a single "auto" stanza.
Detailed report:
interfaces(5) says:
Stanzas beginning with the word "auto" are used to identify the
physical interfaces to be brought up when ifup is run with the
-a option. (This option is used by the system boot scripts.)
Physical interface names should follow the word "auto" on the
same line. There can be multiple "auto" stanzas. ifup brings
the named interfaces up in the order listed.
So it should not make a difference whether the interfaces are defined
within the same "auto" stanza or in seperate stanzas.
In our case, we have the interfaces lo, eth0 and sixxs defined within
one "auto" stanza for each in /etc/network/interfaces - but "ifup -a"
only brings up lo and eth0 and does not touch sixxs.
The /etc/network/interfaces (with the addresses changed):
-------<snip>----------------------------------------------------------
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 10.0.0.1
netmask 255.0.0.0
network 10.0.0.0
broadcast 10.255.255.255
auto sixxs
iface sixxs inet6 v4tunnel
address 2001:1111:1111:2222::2
netmask 64
local 10.0.0.1
endpoint 10.0.0.2
ttl 64
up ip link set mtu 1280 dev sixxs
up ip -6 route add default via 2001:1111:1111:2222::1 dev sixxs
-------<snip>----------------------------------------------------------
If, however, we comment out all those "auto" stanzas and add a single
one
auto lo eth0 sixxs
at the beginning of the /etc/network/interfaces file, "ifup -a" now
brings up all three devices lo, eth0, and sixxs.
A comparison test with "ifdown -a" suggests that "ifdown -a" behaves
according to interfaces(5) and does not make that distinction.
