Hi Dejan, We are glad to contribute. Pacemaker is an impressive project.
I used wget because I had prior experience. I am used to Gentoo systems, so wget is always installed. Since the output isn't restricted to just the information I want, I would have to sed the output anyway and the lack of \n actually makes it easier. If all the other RAs use a single tool, I will adapt the RA. The cgi interface is actually documented in the manual so I hope they also have the decency to keep it stable. If not, I will probably have to do the maintenance anyway. I was already writing a follow-up when I realised that the device needed configuration before the RA would work :) I have added the necessary documentation in comments. It now includes a link to the product manual too. Feel free to copy it to a seperate README if that suits your needs better. Btw, since I found references to some of their other products in the telnet interface, I think they use this firmware for many of their products. It seems likely that this RA will work for some of the other power switching products.

You # can then configure the device with new network settings with that # tool or just do it yourself with a browser. I used the latter # method. I set the device to DHCP and assigned it a static lease. # # Second step is to name the ports so the RA can find which port to # reset for which host. Assign the ports a name equal to the # hostname of your system (without domain part): name a port node1 # if the fqdn of the connected devce is node1.example.com # One of the minus points here is that the names are restricted to 15 # characters so fqdns are not an option. # # Last step is to supply the RA with the IP of the device and the username # and password to allow it to reset ports. You can use the default admin # account or create an account for the RA through the web interface of # the device. # On Mon, 2009-10-05 at 12:42 +0200, Dejan Muhamedagic wrote: > Hi, > > On Mon, Oct 05, 2009 at 10:37:54AM +0200, Johan Verrept wrote: > > Hello guys, > > > > I completed the RA and have attached it.
