Marco | Configuration | Hardware | Adding darkside01 | Wrong MAC address fixed in CERN network setting, now the machine is visible from external network too:
From CERN network (even laptop) can connect by
ssh -XY dsproto@ds-proto-daq2.cern.ch. (same password as local account in ds-proto-daq)
From ds-proto-daq can also connect by:
ssh darkside01
That is to say that the two network card are now associated to two different names.. but the "real" name is still darkside01.
(will fix).

Ben Smith | Configuration | Hardware | Failed to talk to steering module from DAQ PC | I have failed to communicate with the steering module arduino from the DAQ PC.
The steering module has the most bizarre communication protocol of any device I have used:
* it has a static IP address (192.168.121.2)
* if something connects and sends a command, it doesn't send a response to that device - it sends responses to a different static IP address on a fixed port
* before a device connects, it's ethernet port is not open all the time - it turns it on for a brief period, and if something connects during that period, it remains on; if not, it turns off for a while. I'd estimate something like on for 500ms, off for 500ms.
We are currently using a macbook to connect to the steering module. The macbook is statically assigned IP address 192.168.121.1. When pinging the steering module, then first few pings fail with "no route to host". Eventually one of the pings coincides with the steering module having its ethernet on, and then the steering module keeps its ethernet on and the rest of the pings succeed.
We bought a new NIC for DAQ machine. I assigned it same static IP address (192.168.121.1), added a hole in the firewall (and even tried turning the firewall off for a bit), ensured the correct interface was used for connections to 192.168.121.0/24, but we never get a route to the steering module.
I have run out of things to try (but I may have missed something). My hypothesis is that linux isn't able to negotiate a connection quickly enough, but I may be wrong. It is my last evening at CERN, so I have returned the steering module to be connected to the macbook. Shifters will continue to have to manually change channels rather than having it automated by midas.
I hope that future versions of the steering module will have a more normal network protocol - open a server socket (static if must be, but preferably on DHCP), wait for connections, reply to commands on that same connection. |

Ben Smith | Configuration | Hardware | Adding darkside01 to the network | The analysis server from Roma (darkside01) is now connected to the local network. It is not yet connected to CERN.
There are 2 network ports on the rear of the machine:
* The port labelled "1":
* MAC: 9c:71:3a:22:d5:62
* Name: enp2s0f0
* Configured for DHCP
* Connected to local switch
* Assigned IP 192.168.1.10 by ds-proto-daq
* The port labelled "2":
* MAC: 9c:71:3a:22:d5:63
* Name: enp2s0f1
* Configured for DHCP
* Should be connected to CERN network
I have set up password-less ssh between ds-proto-daq and darkside01.
There are 3 problems connecting to the CERN network:
1) The long cable that was created does not work. I tried using it to connect ds-proto-daq to socket 0001/06 (i.e. the socket ds-proto-daq is normally connected to) and there is no link light - the cable is broken.
2) Socket 0001/07 does not seem to be operational. I tried connecting ds-proto-daq to socket 0001/07 using the cable we know works, and there was no link light. Either CERN have disabled the connection intentionally, or it is broken.
3) When I used the good cable to connect to the good socket (0001/06), CERN claimed the machine was unregistered. Marco told me that the interfaces have MACs 9c:71:3a:22:d6:4[ab] (rather than 9c:71:3a:22:d5:6[23]), so presumably the wrong MAC addresses were registered with CERN.
So, we need to register the correct MACs, fix the cable, and either get 0001/07 working or connect to a different socket. |

Ben Smith | Routine | Software | New "run type" selection page | I made a new page that makes it easier to switch between laser/noise/physics runs.
It handles setting the most common chronobox trigger settings, and the V1725 self-trigger thresholds.
For the latter, it assumes that the baselines are at 15500. A suggested workflow would be to run
"equalize_baselines.py" in the morning to ensure all channels are at 15500, then you can use this
page to set the self-trigger thresholds for the rest of the day/week without using the python scripts.
The page is available at https://m-darkside.web.cern.ch/?cmd=custom&page=Run%20type |

Ben Smith | Problem Fixed | Software | Increased max waveform length that we can take | I've increased various thresholds so that we can now take 3000us (3ms) waveforms.
The changes are:
* /Experiment/MAX_EVENT_SIZE in ODB is now 50,000,000
* /Experiment/Buffer sizes/SYSTEM in ODB is now 500,000,000
* max_event_size for V1725 frontend is now 45,000,000 (we use this in several places, so I now have `#define V1725_MAX_EVENT_SIZE 45000000` in v1725CONET2.hxx)
* event_buffer_size for V1725 frontend is now big enough for 10 of these largest events
The main data-taking works smoothly with 3ms traces, albeit at a low event rate.
However protoDisplay segfaults after a few events. The backtrace is random each time, so we're clearly overflowing a buffer somewhere. I will try to look into it, but it will probably be painful and I don't think it's the highest priority issue to fix (it works "fine" for the usual 200us waveforms). |
