I'm running miniSAPserver 0.3.1 under MacOS Tiger Server 10.4.2. It compiled fine and runs OK serving SAP to the local subnet.

But other subnets cannot see the announces, and a packet snoop says the TTL is set to 1, even though my cfg file specifies sap_ttl=255. I've tried it on other values (12 say) but still no change at our core router.

This is an IPv4 network.

Does anyone have miniSAPserver running on a multi-segment network? On which OS?

thanks
George

Its a bug..

in broadcast.cpp

line 100

Change

if (setsockopt(fd6, IPPROTO_IP, IP_MULTICAST_IF,

to

if (setsockopt(fd4, IPPROTO_IP, IP_MULTICAST_IF,


Someone accidently Changing the fd6 TTL in the IP4 section.
This makes it work

Thanks

Thanks Craig,

Actually, line 100 is already like that but using the same principle I changed line 111 from
to
make clean etc and all is well. My SAP announces are now broadcast beyond the local subnet.

thanks very much for your help,

George


PS - Are you the maintainer of this package? If not I'll post a message to the developer list about this change.

Fixed in today's release 0.3.2.
Thanks.
