next in thread | raw e-mail | index | archive | help
I started with a fresh 5.3-RELEASE install and then upgraded the kernel
source to 5.3-STABLE before installing a new kernel. I now find that netstat
fails to show any Internet sockets ('netstat -finet' and 'netstat -ptcp'
give nothing, 'netstat' shows only Unix domain sockets)
I didn't do a buildworld/installworld, but I've tried a make / make install
on netstat itself, and also on the libraries it depend on (libkvm, libipx
libnetgraph, libutil) but it still doesn't work. It also depends on libc,
but I've not rebuilt that on the basis that nothing significant seems to
have changed recently:
# cd /usr/src/lib/libc

Another machine which I have, running 5.3-RELEASE, has a working netstat,
and that's also compiled without INET6.
My kernel does have 'device mem' in it (I only removed INET6 and unnecessary
device drivers), and a search on Gnats, and FreeBSD-current/questions doesn't
turn up any answers. I see nothing recent in /usr/src/UPDATING.

Any other suggestions where I can look to fix this? Do I really have to do a
buildworld?
Thanks,
