Nick, thanks for the info…is there a way for me to make a feature request? I would suggest a way to list banned ip’s and a way to un-ban an ip would be helpful.
Thanks!

I have it set pretty aggressively and occasionally, someone gets banned who should not. I looked up how to unban an ip and I see references to “fail2ban-client” but that command does not work in the container. Is there another way to remove a banned ip from the list? Is there a way to add fail2ban-client to the container? If you're using the 1.6.0 container, the implementation is actually not based on Fail2Ban, it's a Guacamole-specific extension that tracks failed logins based on client IP address and blocks those client IPs if they exceed the specified threshold for failed logins within a certain amount of time. The documentation for it is here: https://guacamole.apache.org/doc/gug/auth-ban.html#installing-enabling-brute-force-authentication-detection<https://urldefense.proofpoint.com/v2/url?u=https-3A__guacamole.apache.org_doc_gug_auth-2Dban.html-23installing-2Denabling-2Dbrute-2Dforce-2Dauthentication-2Ddetection&d=DwMFaQ&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=FAi7_Un_xIwqyE1tNdU-gb08bRZLlfxR_VZo5-zbQF0&m=RO197TLEWq-OHw43zt1FG5jhhs2LzuSfWCPG7tRIikY7EkIZqi9omK1fKjlfZjML&s=sOOSKak3jExPbGXrAoNEIBgZJdvG_RZ1eLkrXX9oFz0&e=> There currently is no way to affect the list of IP addresses (e.g. remove addresses from the list) - you simply have to allow the timer to expire. There are some configuration parameters available in the document linked above that help you adjust things if you need to tune the duration of the lockout, the number of failed attempts, etc. -Nick ________________________________ This email has been scanned for spam and viruses by Proofpoint Essentials.
