Is the RTCM and the server on the same Ethernet LAN at the same location? Are you using an Ethernet switch or a hub? If you are using a switch then why are you not running everything full duplex? On Sat, May 21, 2016 at 3:02 PM, info@rainerbertsch.de < info@rainerbertsch.de> wrote:
Hi there,
Since November, we are trying to build a voting system. We need some help please !
Hardware: Supermicro Intel Atom D525 (we also tried a RaspberryPi and an other computer) Software: Since yesterday DIAL from Alllstar-Homepage (Before we tried it with ACID) RTCM from Micro Node, Mark, we have 4 of them and tried all of them Garmin GPS 18x LVC, also wie tried 4 of them.
Error: More or less often the RTCM switch in the offline mode. When there is traffic very often. But not if at the same time there is a telnet connection from any computer to the RTCM.
We suspect a networking problem between our asterisk-server and RTCM Network-Card is set to 10 MB / s half-duplex like in the RTCM.
From tcpdump from server to rtcm we got:

Does anyone have an idea what it may be ? Why there is no problem with telnet at the same time and how can we run the system without this workaround
