Description Denis Ovsienko 2013-11-28 10:25:29 UTC

Description of problem: there is an important file missing from the RPM. ahcpd needs two executables to perform address management. The first is a compiled binary (/usr/sbin/ahcpd in the current package) and the second is a shell script (/etc/ahcp/ahcp-config.sh by default, not currently packaged but available in the source tar.gz). The shell script normally performs actions based on environment variables set by the compiled binary. The compiled binary never does direct management of addresses.

Version-Release number of selected component (if applicable): ahcpd-0.53-4.fc19.x86_64

How reproducible:

Steps to Reproduce:
1. take two hosts and make sure ip6tables don't block UDP port 5359
2. configure host A as AHCP server and start ahcpd
3. configure host B as AHCP client and start ahcpd
4. (optinal) watch packet dump with the development version of tcpdump and see the exchange occurs similar to this: https://raw.github.com/the-tcpdump-group/tcpdump/master/tests/ahcp-vv.out
5. Copy ahcp-config.sh from the repository to /etc/ahcp/ahcp-config.sh and restart the client to see it helps.

Actual results:
Protocol exchange completes successfully but the allocated address isn't assigned to the interface.

Expected results:
The allocated address get assigned.

Additional info:
The current systemd helper file (/usr/lib/systemd/system/ahcpd.service) has network interface name hardcoded and may be non-functional. ahcpd needs to be run from the command line like this: ahcpd -d 5 -t 300 -c /etc/ahcpd.conf wlp2s0

Comment 1 Gwyn Ciesla 2014-02-21 15:51:55 UTC

I've updated the RPM to include ahcp-config.sh and added -d 5 -t 300 to the service file, but left the interface hard-coded, as there isn't a good way to choose a default.  It can be copied to /etc/systemd/user/ and modified.

I've placed a build here:

See if this is better.

Comment 2 Denis Ovsienko 2014-02-27 08:19:56 UTC

Thank you for the update. I hope to test the new package this weekend.

Comment 3 Denis Ovsienko 2014-03-03 06:17:24 UTC

This build manages the IP address and nameservers OK (given the interface name is correct as noted above).

Comment 4 Gwyn Ciesla 2014-03-03 18:37:01 UTC

Excellent, I'll get updates out.
