If the hostname of a SRW2008 switch contains non valid characters for FQDN (fully qualified domain names) the web interface will not log the user on but repeat the log on screen in a loop.
Example:
The hostname of the switch is: deau_ls001
(note the underscore in the name)
The companies domain name is: acme.com
The DNS server of the zone acme.com will resolve an IP address for "deau_ls001.acme.com" as 192.168.1.254.
Then:
If you use following URL in the webbrowser: http://deau_ls001.acme.com.
The web site will appear, but any subsequent log on attempt will fail.
If you use the IP address in the URL instead: http://192.168.1.254
The log on procedure completes successfully.
Recommendation: Use only valid characters in hostnames
Tested with firmeware: 1.0.2 and 1.0.4
Note about valid charatcters in domain names from wikipedia:
Restrictions on valid host names
Hostnames are composed of series of labels concatenated with dots, as are all domain names[1]. For example, "en.wikipedia.org" is a hostname. Each label must be between 1 and 63 characters long, and the entire hostname has a maximum of 255 characters.
RFCs mandate that a hostname's labels may contain only the ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen. Hostname labels cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted.
