Remove the "access-class 23 in" under the line vty 0 4. The access-list is probalby preventing you from coming in.

do you have an ACL 23 to permit you network as the following

access-list 23 permit 10.10.10.0 0.0.0.7
access-list 23 permit 10.10.10.0 0.0.0.255
access-list 23 permit 192.168.1.0 0.0.0.255
access-list 23 permit 192.168.0.0 0.0.0.255


plus here is a working config.

line vty 0 4
 access-class 23 in
 exec-timeout 120 0
 length 0
 transport preferred all
 transport input all
 transport output all
