Hi Christoph,
try adding -net.slp.interfaces=192.168.1.121 to the list of java
properties to make jSLP bind to this (external) interface.

Hi Markus
thanks for your input! That gets me one step further, but I still get an exception during start up and I still see 127.0.1.1 in the middle of it.

Hi Christoph,
what is the content of /etc/hosts and the output of ifconfig on the Pi?

Hi Markus, hi Wim,
thanks for your replies! The weekend has been busy, but now I'm eager to get this working.
@Wim: Thanks for your inspirational talk at ECE in Ludwigsburg! Your presentation was the reason I wanted to try this stuff myself 
I don't know what you mean with "add the property on the remote end". I compared my script to the start script of your pipolos and it looks like you're basically doing the same thing, in the sense that i'm also setting net.slp.interfaces and ecf.generic.server.hostname when I start the server on the pi.
I get the feeling that my issue is probably not connected to ECF but has more to do with the setup of the pi itself. I admit that I am not very komfortable with linux yet.
ifconfig
eth0 Link encap:Ethernet HWaddr b8:27:eb:ab:28:b9
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
wlan0 Link encap:Ethernet HWaddr 00:0d:81:ae:df:05
inet addr:192.168.1.121 Bcast:192.168.1.255 Mask:255.255.255.0

collisions:0 txqueuelen:1000
RX bytes:391016 (381.8 KiB) TX bytes:28622 (27.9 KiB)
I've also tried this with lan (eth0) which uses the ip 192.168.1.120 with the same result. The ip is provided by a dhcp server which reserves 192.168.1.121 for pi01 over wlan0.
/etc/hosts
127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
127.0.1.1 pi01
I tried to change the last line to "192.168.1.121 pi01" which leads to
16:15:43.322 ERROR ch.ethz.iks.slp - Exception during sending of SRVREG - xid=23438, locale=en_GB, url: service:ecfosgirsvc://ecfosgirsvc://192.168.1.121:32565/osgirsvc_MF/pJaj+VOw71ZqWCthAHXHogLw=, serviceType: service:ecfosgirsvc, scopeList: [default], attList: [(ecf.generic.server.hostname=192.168.1.121), (endpoint.service.id=83), (ecf.endpoint.ts=1416240935602), (endpoint.package.version.org.eclipse.ecf.examples.raspberrypi.management=1.0.0), (remote.intents.supported=passByValue exactlyOnce ordered), (ecf.exported.async.interfaces=*), (ecf.rsvc.id=1), (ecf.generic.server.port=3288), (x-28392-SERVICEIDNAME=\FF\62\33\4e\6e\61\58\4a\7a\64\6d\4e\66\54\55\59\76\63\45\70\68\61\69\74\57\54\33\63\33\4d\56\70\78\56\30\4e\30\61\45\46\49\57\45\68\76\5a\30\78\33\50\51\3d\3d), (x-28392-PRIORITY=0), (objectClass=org.eclipse.ecf.examples.raspberrypi.management.IRaspberryPi), (remote.configs.supported=ecf.generic.server), (endpoint.framework.uuid=404bd8eb-746e-0014-185e-e526cf180d47), (service.imported.configs=ecf.generic.server), (x-28392-WEIGHT=0), (ecf.endpoint.id.ns=org.eclipse.ecf.core.identity.StringID), (ecf.endpoint.id=ecftcp://192.168.1.121:3288/server), (endpoint.id=03f6ccef-743e-4417-98dc-63acb17f8896)]

Hi Christoph,
thanks for the follow up. Without a loopback interface, SLP cannot
detect a locally running Directory Agent [1].
What Raspberry Pi image are you running? It would be good to know if it
has no loopback interface by default.

Cool! and thank you for your compliments.
Are you also running the egg interface? Please note that out of the box pipolos uses a slightly newer version of the raspberry pi examples. In addition, pipolos uses JmDNS and not slp for discovery.
The egg interface can be found here: https://github.com/wimjongman/eggclient
Please note that you also need to supply the java properties:
-Decf.generic.server.hostname=192.168.1.33
-Dnet.mdns.interface=192.168.1.33 // (without the "j") to tell jmdns which network to use
-Dadmin=true // activates the cooking pin
See egg.ini for details.
