Manually add setuid-bit for executables #80

Open JanGaertner opened 3 years ago

JanGaertner commented 3 years ago

Using Version: 1.3.5

Hello,

after I have installed the hpc-workspace and created a ws user and group I confirmed that ws-db is in fact owned by the ws user and has the ws group. I can also create workspaces as root but when I switch to a normal user I cannot execute ws_allocate

The error message I get is: "Error: can not change uid." of Line 906 in src/ws.cpp. From the issue #58 I know that the permissions should have the setuid-bit set. But they do not. Only once I set this manually i can use non root users to allocate some workspace.

It seems to me that this is not the default behavior. What have I done wrong or how should it be done?

all as expected, you just missed the part in the HOWTO to set the setuid by hand.

Could you point to where it is stated in the Admin Guide (https://github.com/holgerBerger/hpc-workspace/blob/master/admin-guide.md)? I cannot find that information

JanGaertner commented 3 years ago

I do not want to say that it is not there, but that maybe this information could be made more visible.

Is the install command from cmake tested? As an idea, to include the cmake --build . --target install command in the how to?

no you are completely right, it was only in the HOWTO file, not in the admin guide. I added a sentence.

I do not test any automatic install, but it might be there by contributions, I am not 100% sure.
