Hi Tony, nope. The GUI gives me a hostname, something like BMC23453234 and it is greyed-out so I cannot change it. The string after BMC is basically the MAC address without any hyphens or so.
However, given I can go to the login page and given I then get rejected by the webserver and redirected to another page, I am not quite sure how that could affect my ability to log in. Something I am missing here? All the best Jörg Am Donnerstag, 21.
