Version-Release number of selected component (if applicable): 1.3.10-4.fc10 (updates-testing) 1.3.10-1.fc10 (updates) How reproducible: Always. Steps to Reproduce (assuming the host has IP 192.168.1.251): 1. Using localhost:631, edit config -> choose default config 2. Enable - Share published printers connected to this system - Allow printing from the Internet - Allow remote administration 3. Save and restart cups 4. Access 127.0.0.1:631 -> works 5. Access 192.168.1.251:631 -> works 6. Access fully.qualified.host.name:631 -> "400 Bad Request" Actual results: 6. Access fully.qualified.host.name:631 -> "400 Bad Request" Expected results: 6. Access fully.qualified.host.name:631 -> works Additional info: cuspd.conf attached.

However, Adding "ServerAlias *" (and restarting CUPS) does not change anything for me. The docs mention "If your CUPS server is accessed using a hostname or hostnames not known to the server itself you must add "ServerAlias hostname" to cupsd.conf for each such name." but I fail to see why CUPS does not know the FQDN of the local system. It's in /etc/hosts and DNS. ... Which precisely turned out to be the problem. The FQDN was stored in /etc/hosts as 127.0.0.1 and apparently CUPS doesn't like 2 IPs for a single FQDN. AFAIC we can close this bug.

[Bug 516018] Re: cups 400 Bad Request for fully qualified host name
Also I think this is important to support HOST.local (avahi/bonjour/ZeroConf) type of name resolution. I have a home network in wich i can't manage the routers dns since it only relays a dns from the cloud and al machines are assigned via dhcp so no static ips. Avahi and Bonjour in Mac and Windows hosts have helped me to manage internal names and services on my lan, having a server with a dynamic ip is not ideal, but is the way It works better on the router side. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/516018 Title: cups 400 Bad Request for fully qualified host name -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 516018] Re: cups 400 Bad Request for fully qualified host name
Hello, I ran across this while having the same error. I'll add this info for others to see... It is best to use the ServerAlias directive with an actual hostname versus the * command Just add it to the end of the cupsd.conf file Example: ServerAlias server-name.your-ip.com Reason:http://www.cups.org/documentation.php/ref-cupsd-conf.html Note The ServerAlias directive is used for HTTP Host header validation when clients connect to the scheduler from external interfaces. Using the special name * can expose your system to known browser-based DNS rebinding attacks, even when accessing sites through a firewall. If the auto-discovery of alternate names does not work, we recommend listing each alternate name with a ServerAlias directive instead of using *. -- cups 400 Bad Request for fully qualified host name https://bugs.launchpad.net/bugs/516018 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Adding ServerAlias * to /etc/cups/cupsd.conf did work. Thank you, Pretto, for you post. This was missing from my Karmic server and Lucid test server. This small change has caused a huge problem.
