Hello all,
I have a LEON3 / XILINX Virtex / Buildroot Linux running on my fpga.
I have a weird issue with localhost :
When there is no default route, ping localhost works fine.
When I set a default route (route add default gw 1.2.3.4), ping localhost doesnt work anymore (but ping 127.0.0.1 still does).
I have checked my /etc/hosts and my /etc/network/interfaces, they are fine :
auto lo
iface lo inet loopback
hosts :
127.0.0.1 localhost
What am I missing ?
Thanks.

Problem SOLVED :
I was missing the nsswitch.conf file in /etc, so the resolv order was
wrong (nslookup localhost was requesting the dns server in
/etc/resolv.conf whereas it should have beeb /etc/hosts)
I just added a nsswitch.conf from an another correctly running linux.

So you're using a glibc-based system, right ? If so, maybe we should
add this nsswitch.conf file to the default Buildroot and make sure it
gets installed when a glibc toolchain is used.

I just ran into the exact same problem, and here is a links to a LFS manual
stating the problem as well :
http://archive.linuxfromscratch.org/lfs-museum/4.1/LFS-BOOK-4.1-HTML/chapter06/glibc.html#AEN2505
So yes I think that should be good to ship nsswitch.conf.
For information, I used the nsswitch.conf file found in my external toolchain
sysroot that was re-created under buildroot, in my case it was at
<buildroot_path>/output/host/usr/sh4-unknown-linux-gnu/sysroot/etc/nsswitch.conf
Kind regards,
Lionel
