Error appears to be due to ifconfig taking 08 as an invalid octal value rather than a binary with leading 0. Error also affects ifup/ifdown if /etc/network/interfaces has similar entries. Values 01->07 accepted as they are valid octal units.
Ifconfig uses inet_aton to check if you provided an ip address, if it says it's invalid, it will try to resolve it with DNS. inet_aton will accept many formats of ip address, dotted-decimal, dotted-octal, dotted-hex, and raw decimal, octal and hex addresses: ifconfig eth1 0x0f.0x0f.0x0f.0x0f ifconfig eth1 15.15.15.15 ifconfig eth1 017.017.017.017 ifconfig eth1 0x0f0f0f0f ifconfig eth1 01234567123 ifconfig eth1 999999999 All of these are valid, although inet_aton doesn't document this. If you provide a string which is invalid to inet_aton, such as an invalid octal, it will try with gethostbyname and then you see the error you mentioned. So, I'm not even sure if this could be considered a bug. In any case, it's libc fault... What do you think? -- Martín Ferrari
