Title
Permission denied (publickey) Error is seen When Accessing Core Shell on syslog-ng Store Box -
Description
Administrators may be unable to access the core shell on a syslog-ng Store Box (SSB) system. When attempting to connect using SSH and launch the core shell, the access attempt fails and returns the error “permission denied (publickey)” -
Cause
This issue occurs when the root user’s login shell defined in the
/etc/passwdfile is changed to a shell that is not listed in the/etc/shellsfile.If the configured login shell is not present in
/etc/shells, it is treated as invalid by the system, which results in authentication failure and the “permission denied (publickey)” error when attempting to access the core shell.This behavior is due to an unsupported configuration
-
Resolution
Verify that the root user’s login shell configured in/etc/passwdis a valid shell and that it is listed in the/etc/shellsfile.Correcting the login shell to a valid entry, will restore access to the core shell.
