Dotaz: SSHD - banner

[muficek]

Ahoj, mám tento "problém".
Rád bych docílil toho, aby když se přihlásím přes putty ke svému serveru, tak aby se jako první zobrazil banner a hned pod ním login následovaný heslem.

V tuto chvíli mi to funguje, ale jinak, než si představuju. To znamená, že nejdřív zadám login, pak se zobrazí banner, který je následován dotazem na heslo.

Já to potřebuji v pořadí: 1=banner, 2=login, 3=heslo.

Poradíte prosím ?
Děkuji.

Tak si ten login nastav do puttyny předem a pak se to zeptá akorát na heslo. Jinak si myslím, že to nepůjde.

Viděl jsem, že to jde, bohužel už nevím u koho. Řešení přes Putty není na místě.

Please note that this feature may not work with third party ssh client such as Putty.

Osobne mam pocit, ze to je vec puttyho, protoze dotaz na uziv. jmeno je plne v rezii puttyho. Tzn kdy se putty rozhodne zobrazit banner a kdy se zeptat na heslo zavisi jen na nem.... Ale nijak podrobne jsem to nezkoumal, takze se muzu mylit...

Taky mám ten pocit. Dotaz na uživatelské jméno podle mého není v režii sshd, to je věc klienta.
