what binaries are required for domain name resolution   
Hi,

With io-pkt-v4 and dhcp.client to get an IP address, what additional binaries are needed so that domain name lookups 
succeed?

e.g.

# ping foo
ping: Cannot resolve "foo" (Host name lookup failure)

When I mount the HDD with my SDP install the look up succeeds, so it appears a binary is needed, but I'm not sure which 
one.

The resolver library is part of libsocket, so if ping
runs at all you have it.  Check out the docs for /etc/resolv.conf.

I think that you need to have a writeable /etc/resolv.conf file.

RE: what binaries are required for domain name resolution   
Thanks all for the suggestions.  The /etc/resolv.conf doc mentions dhcp.client, and 'use dhcp.client' describes the '-m'
 option:

-m           Write resolv.conf data as in-memory configuration strings
              (Neutrino only, default is off)

Using dhcp.client -m seems to do the trick when /etc/resolv.conf isn't available.

Pidin mem from ok system and not ok system as starting point + /etc/hosts config file. 

Perhaps?

Betreff: what binaries are required for domain name resolution

Hi,

With io-pkt-v4 and dhcp.client to get an IP address, what additional binaries are needed so that domain name lookups 
succeed?

e.g.

# ping foo
ping: Cannot resolve "foo" (Host name lookup failure)

When I mount the HDD with my SDP install the look up succeeds, so it appears a binary is needed, but I'm not sure which 
one.
