Provides an SSHD AuthorizedKeysCommand. Needs to be configured in the sshd config file:
|
||||||
|
|
||||||
|
```ini
|
||||||
|
...
|
||||||
|
# The value of -e and the AuthorizedKeysCommandUser should match the
|
||||||
|
# username running gitea
|
||||||
|
AuthorizedKeysCommandUser git
|
||||||
|
AuthorizedKeysCommand /path/to/gitea keys -e git -u %u -t %t -k %k
|
||||||
|
```
|
||||||
|
|
||||||
|
The command will return the appropriate authorized_keys line for the
|
||||||
|
provided key. You should also set the value
|
||||||
|
`SSH_CREATE_AUTHORIZED_KEYS_FILE=false` in the `[server]` section of
|
||||||
|
`app.ini`.
|
||||||
|
|
||||||
|
NB: opensshd requires the gitea program to be owned by root and not
|
||||||
|
writable by group or others. The program must be specified by an absolute
|
||||||
|
path.
