AnyConnect funciona bem com o Windows XP.
No Ubuntu Linux 9.10 de 32 bits, eu baixei o anyconnect-linux-2.4.0202-k9.tar.gz, instalei-o e tentei conectar-me ao mesmo firewall ASA. Ele falhou com:
>> state: Connecting
>> notice: Establishing VPN session...
>> error: AnyConnect package unavailable or corrupted. Contact your system administrator.
>> notice: Connection attempt has failed.
>> state: Disconnected
>> state: Disconnected
Então eu baixei o anyconnect-linux-2.4.0202-k9.pkg do cisco.com e o instalei no flash do ASA:

Tentei novamente com o Linux - falha exatamente da mesma maneira. O log ASA diz:
Group <DfltGrpPolicy> User <foo> IP <X.Y.Z.K> WebVPN session terminated: User Requested.
Estou sem ideias. Alguma sugestão?
