TLS errors

[Hans Schnehl]

Thx for the fast replies, I wasn't really scared but rather curious about what the logs were saying.

I read the message, and there is a simularity, mayber there is something about openssl
with freebsd, as Scott Bennet  lso runs a freebsd machine.
Mine is running  now with freebsd7, but the logs did show up also with fbsd6-stable.

All correct, the ones I cannot really understand are those:
Jan 02 12:46:14.711 [debug] crypto error while performing RSA decryption: oaep decoding error (in rsa routines:RSA_padding_check_PKCS1_OAEP)
Jan 02 12:46:14.711 [debug] crypto error while performing RSA decryption: padding check failed (in rsa routines:RSA_EAY_PRIVATE_DECRYPT)

and the ones with:
Jan 02 12:45:57.965 [info] TLS error: <syscall error while writing> (errno=1: Operation not permitted)
Jan 02 12:45:57.965 [info] connection_handle_write(): tls error. breaking.
Jan 02 12:45:57.965 [info] TLS error: <syscall error while writing> (errno=1: Operation not permitted) 
 

what should be not permitted ?

I reckon one reason for bandwidth behaviour is, the node runs with another secret-key, as I lost the original. 
It may take some time until it is 'named' again, so the 7 authorities handle the node  
differently. 
How long does it take nowadays for a registered name to expire and the name to be used for (in my case the same) 
new machine ?

I had with Tor 0.2.0.7 and ..06 a full utilizatiojn of bandwidth within 
roughly 2 to three hours after reconnection,
but that was lost somewhere with the next -0.8- to todays -0.15.
