Network-related Problems381– RFC2617: HTTP Authentication: Basic and Digest Access Authentication(Basic authentication support only, others are not supported)– RFC2817: Upgrading to TLS Within HTTP/1.1– RFC2818: HTTP Over TLS• HTTP/HTTPS scheme compatibility, GET/CONNECT/HOST method compatibilityIPv6 AddressesRestrictionsThis section explains the restrictions on network connection using an IPv6 address.CentreWare Internet Services• When SSL is enabled, “http://[IPv6 address]” entered on a web browser is notredirected to “https://[IPv6 address]”. Directly specify “https://[IPv6 address]”.Printing• The following operating systems support IPv6 printing.– Windows Vista– Mac OS except Mac OS X 10.4 and earlier– Linux distributions with CUPS that supports IPv6• The WINS protocol does not support IPv6 communication.• On an IPv6 network without a DNS server, the machine cannot be connected toWindows Vista via SMB.• Netware does not support IPv6 communication. Use IPv4 for Netware.• Bonjour does not support IPv6 communication. Use IPv4 for Bonjour.Scanning• When IPv6 is enabled and IPv4 is disabled on the machine, the Browse function ofthe Scan to PC (SMB) service is not available.• In an IPv6 network with no DNS server installed, the file transfer using the Scan toPC service fails if a destination server is specified using the computer name. Directlyspecify the IPv6 address.Discovery• IPv6 devices cannot be searched in UPnP. Use the WSD discovery function for IPv6device search.Authentication• In an IPv6 network without a DNS server, SMB authentication fails if an SMB serveris specified using the computer name. Directly specify the IPv6 address.Connection to External Applications (Custom Services)• External applications, such as DocuShare, cannot be specified in IPv6 addressformat. The machine supports only the domain name format or the IPv4 format toaccess external applications. In IPv6 environment, use a DNS server and specifyapplications in domain name format.
