SDR error message....

[Alexander Kushnirenko <kushnir@pccmu1.fnal.gov>]

Hi,

I took SDR v2.4 from unstable distribution.  When I launch it I got the error
message 

<pccmu1> sdr
setsockopt - IP_ADD_MEMBERSHIP: Protocol not available
setsockopt ttl: Protocol not available
ttl: 0
setsockopt - IP_ADD_MEMBERSHIP: Protocol not available

Indeed ttl is not specified in /etc/protocols.

What should I do about it?

Thanks,
Sasha.
