Error

Invalid message received during Encryption STS handshake (pre-2.1.2 client trying to connect?). Encryption is enabled on this remote daemon, but it does not appear the client has encryption enabled. Disconnecting

A client using TTM 2.1.1 or earlier attempted to connect to a daemon that uses encryption.

Error

Proxy client advertising HALF STS

A client is connected and encrypted using Anonymous Authentication and Encryption (half STS).

Info

Proxy client attempting to login with no encryption parameters while XTRH is configured for encryption only. Disconnecting!

A 3.1.X or 3.2.0 client that does not have encryption parameters is trying to connect to a 4.2.2 or later Remote Host that is configured for encryption and has allow_insecure_connections disabled.

Info

Proxy client advertising FULL STS while this is not supported. Disconnecting!

A 3.1.X or 3.2.0 client that has encryption enabled is trying to connect to a 4.2.2 or later Remote Host.

Info

Proxy client attempting to login unencrypted, connection will be unencrypted.

A 3.1.X or 3.2.0 unencrypted client is connecting to an encrypted 4.2.2 or later Remote Host that has allow_insecure_connections enabled. The result is an unencrypted connection.

Info

Proxy client advertising HALF STS, encryption is disabled. Disconnecting!

A 4.2.2 or later client that has encryption disabled is trying to connect to a 4.2.2 or later Remote Host.

Log File Entry: Base Filtering Engine Enabled

TT requires you to disable the Base Filtering Engine (BFE) Windows service when TTM is installed on Windows Vista, Windows 2008 Server, or Windows 7. Failing to disable this service so allows Windows to block all PGM traffic.

If the Base Filtering Engine (BFE) Windows service is enabled, TTM adds the following error message to the ttmd.log file:

ERROR: Base Filtering Engine detected, no PGM traffic will be received by TTMD.
