Hello,

have you guys experience scanning the FreePBX 17 (Sangoma) server using Qualys and you are having problem to authenticate the server?

Thanks

The failure on server for authentication occurs during the post-login shell validation phase because the expected shell response is not received within the allotted timeout period.

what was recommend by Qualys was to review the shell environment, login scripts, banners, or any post-authentication processes on the affected host that could be delaying or preventing the expected command output from being returned.

Anyone have some suggestion where to start the this checking?

Thank you in advance.

Are you able to increase the scanner’s timeout length ? How long is it currently set for ?
