| Frequently Asked Questions: |
| Q: | How can I gain the remote access to GMCA computers? |
| A: | The remote access needs to be requested when applying for beamtime.
There is a checkmark in the user account setup utility that enables remote access after
the beamtime is granted. |
| Q: | What network should I have in order to be able to collect data remotely? |
| A: | Please read the Speed Benchmarking page. |
| Q: | How long can I use the remote access capability? |
| A: | The NOMACHINE remote access is provided to two beamline computers
('acquisition' and 'processing') during allocated beamtime and solely for collecting
and analyzing data in parallel. Additionaly, two more days SSH-only access is provided
to our second-day area computer solely for backing up data. Please request SSH/SFTP
connection details from your host. |
| Q: | Can I have an extended or permanent remote access? |
| A: | Long-term remote access to GMCA systems is not allowed.
The major consideration is to prevent overloading our systems which may slow
down data collection or processing for the group that is currently doing an
experiment. |
| Q: | Why do I have to login on different systems for 23ID-D and 23ID-B? |
| A: | The two beamlines have independent computing systems with different NX
servers, different account management, different central storage and different subnets. |
| Q: | What types of operating systems can I use for remote access? |
| A: | Supported platforms are Mac OS X, Windows, Linux and Solaris.
Check NOMACHINE web site for additional details. |
| Q: | What are the requirements to hardware?
|
| A: | Network connectivity must be ADSL or faster.
Minimum video resolution is 1280x1024, but 1600x1200
or higher is strongly recommended. |
| Q: | Are dual monitors supported? |
| A: | Not yet, at least on Windows platforms.
See the NOMACHINE article
for additional details. |
| Q: | What are the known problems? |
| A: | If Windows computer has Cygwin installed and the cygwin.dll
is in the system path, that may cause a conflict with NX client installation.
Upgrading cygwin and NX to their latest versions usually fixes the problem.
Alternatively, remove the cygwin directories from the system path.
Simultaneous remote and local access to the same account on the computer
running NX server may cause conflicts in GNOME settings. Therefore, users
present at the GMCA locally should not login on the blXws2 and blXws6 workstations
if the remote access session is in progress. |
| Q: | How can I learn more about GMCA remote access? |
| A: | Study our Remote Operations Manual for Users.
Also, check our remote access demo (please turn on the sound!). |
