How can delete server_connections? #113

Closed perrfect closed 4 years ago

perrfect commented 4 years ago

Hello. I want to delete "server_connections", because I changed my certificate and when i want to enter my "server_connections" i get error:

http://vpn-test:1515/server_connections/1/ 1.9.6 AssertionError /root/strongMan/strongMan/apps/server_connections/forms/SubForms.py in fill, line 396 /root/strongMan/env/bin/python3 3.6.8 ['/root/strongMan', '/root/strongMan/env/bin', '/root/strongMan/env/lib64/python36.zip', '/root/strongMan/env/lib64/python3.6', '/root/strongMan/env/lib64/python3.6/lib-dynload', '/usr/lib64/python3.6', '/usr/lib/python3.6', '/root/strongMan/env/lib/python3.6/site-packages']

So, I want to delete this configuration and create new, but don't want to delete my users from "EAP Secrets". How can I do it?

What do you mean with _"delete "serverconnections""? What exactly did you do?

perrfect commented 4 years ago

I mean that I want to delete my existing configuration, because when i want to see the configuration or change i get error.

I deleted my existing certificate from server, but i didn't delete the certificate from my configuration.

I deleted my existing certificate from server, but i didn't delete the certificate from my configuration.

What does that mean? Did you modify the database manually?

perrfect commented 4 years ago

No. I deleted my certificate from tab "Certificates". And after that i restarted strongMan as service. But i didn't delete my certificate from "Server Connection" tab and get error.

Do you have any ideas how can i restore my configuration?

Do you have any ideas how can i restore my configuration?

Presumably, the database is in an inconsistent state. So I guess you'd have to manually add a certificate (or rather identity) entry with the same ID as the previous one (the one still referenced by the connection). Otherwise, deleting the connection entry might be the only option.

I saw that there is a check that should prevent deleting certificates if they are in use by a connection. I wonder why that didn't work here.

Hi. Thank you for reply I've been testing new configuration and noticed that when I create new "Connection" and upload new certificate (on tab "Server Connections", field "Server certificate") and after that delete this certificate from tab "Server certificate", get error which i described above.

I finally had some time to look into this. It turns out that the check that should prevent deletion of in-use certificates I mentioned above was not correct. The code was copy-pasted from the client connection app without necessary modifications to take into account properties of server connections. I pushed a fix to master.
