I've run into a weird problem. I have an ASA5505 with a very slow Internet connection that acts as an EasyVPN client. I want to upgrade the software image on it but given the speed of the Internet connection, it's going to take about 2 hours. Every time I try to upload the new image to flash, it stops after 1 hour. I guess it's because of the SSH session idle timeout value which is set to 60 minutes (max). Is there any way I can fix this problem? Thanks.
