Environmental Variables for EPICS
...
- Search for "env" in the search box.
- Bring up "Edit the system environment variables".
- Click the "Environment Variables..." button.
- Add or modify the EPICS variables; EPICS_BASE, EPICS_CA_ADDR_HOST and EPICS_HOST_ARCH. Example.
- Reboot.
NFS Mount
The target computer mounts the E906/E1039 network disk (i.e. "/data2") to record slow-control data. The disk is automatically mounted when the main user logs in. It was configured on 2021-11-21 by the following procedure.
...
- Network path = "192.168.24.160:/mnt/seaquestdsk0" — Found in "e1039gat1:/etc/fstab"
- UID = 500 (e1039daq) and GID = 10391 (e1039sc) — Found by "ls -n /data2/e1039_data/slowcontrol_data"
...
Open "regedit" from the task-bar search box.
Expand HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> ClientForNFS -> CurrentVersion -> Default.
Create a new DWORD value (via right-click menu), with name = "AnonymousUid" and value = "500".
Create a new DWORD value (via right-click menu), with name = "AnonymousGid" and value = "10391".
...
- Open "command prompt" from the search box.
- Execute this command: "mount -o anon -o nolock -o fileaccess=775 \\192.168.24.160\mnt\seaquestdsk0 Z:". Note that "-o anon,nolock,fileaccess=775" does not work!
- Screenshots: Command prompt. and Z: folder.
Misc Settings
The following settings were made, as instructed in another page.
- Git repository
- NFS mount
- Disabling automatic Windows update
...
Create "nfsmount.bat" with the following contents:
...
Notes:
- The mount option "-o nolock" was necessary to avoid an error when creating a file: "0x80070021: The process cannot access the file because another process has locked a portion of the file."
- "UID = GID = 65534" didn't work since the write permission of "/data2/e1039_data/slowcontrol_data" is not granted.
- It is a bit anxious that any user on the target computer can (re)move any network files by mistake, where such mistake can happen more easily on graphical interface. A precaution is wanted.
- The registry can be edited via the command prompt. Have a try next time:
- New-ItemProperty HKLM:\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default -Name AnonymousUID -Value 500 -PropertyType "DWord"
- New-ItemProperty HKLM:\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default -Name AnonymousGID -Value 10391 -PropertyType "DWord"

Disabling Automatic Windows Update
There are several ways of disabling the automatic Windows updates on Windows 10 Pro. Let's use "Group Policy" on the target computer. It was disabled by the following procedure on 2021-10-25.
- Search for "gpedit.msc" (using the task-bar search box) and execute it.
- Go to "Computer Configuration" -> "Administrative Templates" -> "Windows Components" -> "Windows Update".
- Double click "Configure Automatic Updates" policy setting and select "Enabled".
- Choose "2" ("Notify for download and notify for install") under "Configure automatic updating" section.
- Click "Apply", followed by "OK".
