If I SSH to a remote server, is it be possible for the admins of that machine to use my SSH session to send data back down the connection and do something to my local PC? I use DSA keys and do not allow password logins to my SSH server, and I do not allow root access. If it would still be possible despite these precautions,  could you explain how it is done with code/links so I can understand?Another thing I am worried about is that if I connect to the remote server, the admins may be able to hijack my pts session and simply type exit to get to my PC. Again, please let me know if this is possible and if so please provide code/linksI've done a bit of googling and turned up nothing so far.
