I have this small DNS

[Odd Arild Olsen]

I have missed some messages from the list lately, but here is a 
comment/question on the subject:

Leading 0 number in a part of a dotted quad IP-address  taken as octal, e.g. 
192.168.054.100->192.168.44.100:
I assume this bug is caused in the inet_aton function since the first release 
only used strings for IP and RIP. But is this a bug?

IP-addresses are often called dotted decimal, but check the aton_inet source 
in uClibc libc/inet/addr.c:
 * Each part may be decimal, octal, or hexadecimal as in ISO C.
 * 0x or 0X    -> hexadecimal
 * leading 0   -> octal
 * all else    -> decimal
This indicates that octal numbers are allowed for. There is probably a RFC 
which defines this exactly, I don't know yet. 

If we want to follow this, the formats now used in scdns for the sscanf 
functions should be changed from %u to %i, or we can revert back to handle 
the IPs as strings. 

Newest version is now http://www.oao.no/filer/scdns-22.tgz
