How can I test this locally to ensure it works > for me? if-hurd.c and privsep-hurd.c are mostly stubs because setting up IPv4 is pretty common amongst all platforms and the only hurd specifics we need is the ability to get the interface index and hardware address - other platforms can get this via getifaddrs and look at AF_LINK/AF_PACKET address which the Hurd lacks. The Hurd also lacks important things like interface/address/route state change notification. Anyway..... Checkout the hurd_test branch ./configure make sudo make install Ensure pfinet is running sudo dhcpcd And the 10-pfinet hook script we installed should then configure pfinet on the fly with the needed details and configure resolv.conf for you. IF lwip only supports one interface then it could be configured the same way. Otherwise we'll need to start adding ioctls to if-hurd.c to handle setup. > > > One thing I lack the time to do because I am very much limited by my > > inability to upgrade > > much on my Hurd VM is fix the ethernet header disater. > > If you can get any changes upstreamed to Hurd libc I would appreciate that > > greatly. > > > > See here on my hurd_test branch: > > https://github.com/NetworkConfiguration/dhcpcd/commit/cbd462a9a671a5bd20212eba4619aca5f4e8bc5e#diff-9625d3bf762014910c77568e8fab6f16ed8a0c3891483266d32e47793ec9b41e > > > > > > #ifdef __GNU__ > > #include <net/ethernet.h> > > #include <net/if_arp.h> > > #else > > #include <netinet/if_ether.h> > > #endif > > > > I should NOT have to do this. > > Every other OS dhcpcd compiles on (it's a long exhaustive list) pulls in > > what I need from netinet/if_ether.h > > Relevant upstream bug: > > https://sourceware.org/bugzilla/show_bug.cgi?id=11142 > > > > Again, if you can progress that so I don't have to special case Hurd each > > time I want some ethernet stuff I would greatly appreciate it. > > Yes, of course.

No need to bypass it, dhcpcd configure works out it's Hurd and compiles in bpf-hurd.c Thanks Roy
