Our network recently crashed due to some possible changes on our Cisco 2651 router. It took about 3 hours to fix the issue, but we never found out what caused it. We basically had to upload a back up of our configuration to the router for it to work again. We would like to pull the syslog messages off the router but we are not really sure how to so this. We have tried but there is no clear cut step-by-step way to acheive this. Also, is it possible to log telnet sessions and trace them back to an IP address? And one last question, will the logs tell us what changes were made and where the changes came from (IP, username, etc.) Any help would be greatly appreciated!

How to pull log files from Cisco 2651

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
