Re: Permissions question...
Let me learn a bit more about Ubuntu groups, and I will return later. I clearly am beyond my knowledge base here...

Re: Permissions question...

Re: Permissions question...
Dave,
Your file permissions are fine for read and write.?? -rw-rw-rw- 1 dcole dcole 3 Jun 11 05:20 /home/dcole/scripts/solar_data/incoming/lotwcount.txt. What group is node red being run from? You can check /etc/group. If it is not in the same group you can add dcole to the node red group chown 'node-red-group':dcole //home/dcole/scripts/solar_data/incoming/lotwcount.txt Can you even write to the file? From all the above posts, I am getting the impression you can't even write to it. At this point Dave,? I would just work with Adrian on this.? Too many cooks in the kitchen.?? -- Mick, W8BE |

Re: Permissions question...
Just did a very fast scan of that info, let me get setup for sudo, with no password, then try again...

Re: Permissions question...
I believe you are asking if there is any code in the section for code for the file node, (is that called a function as well as a node?), nothing is in that part.

Hi Adrian,?
I'll check if it's a utf16 issue... and if that fails, I'll issue a temp update with a radio type dropdown as you suggest.? I'm out for breakfast now and I have lawn mowing etc to do later.? But I'll issue an update later. Greg ve9gfi |

Re: Permissions question...
Let me absorb this a bit... I am quite new to Node-Red, and have never even heard of the visudo before...

I have learned to understand what changes I make first though, so I am going slow and careful here... I brought up visudo, and I don't see dcole anywhere... If all of this is to insure dcole can use sudo, I can already, however I do need a password when I invoke sudo. 73, and thanks, Dave (NK7Z) ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst.

Re: Permissions question...
BTW, the file is created by a perl script I run under dcole, same group the file is owned by.

If the permissions are set correctly the only other reason I would think node red could not read the file is that node red is not apart of the group. |

#file-notice
Hi Adrian, ? I created two dynamic dropdown lists, and each one works. Then I added a Switch node to select what list should be used, based on the getradio response.? ? I'm stuck ... but I wanted to share that this will work for your radio and mine, automatically, if I can get the Switch node to cooperate. I tried using both the msg.payload output from MQTT and the flow.getradio variables... same response (not working). It's Saturday here, and I need to run the roads ...? If you see my error, please let me know. ? EDIT>>>? The one thing that comes to mind is that perhaps the getradio and mqtt string is UTF16 and is not matching my typed in string. Greg VE9GFI ? |

Re: Permissions question...
Dave
Perhaps the file is in a directory that requires administrative privileges?? I suggest two ideas. 1- Move the file to different locations, like the documents directory. 2- prepend a "sudo" to your Node-Red read file command, with a password. ?The command will look like this: ? "sudo -S <<< "password"?

Permissions question...
Hi,
I am trying to read a file under Ubuntu... The file is under my home directory, as shown in the screen capture... I am using readfile, and all permissions are set to read/write for everyone on system, for the target file. I know this is some sort of permissions issue, but I don't know what it is... Any suggestions? -- 73, and thanks, Dave (NK7Z) ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst. Director, NW Division, Technical Resources |
