GNS3模拟cisco7200与实体系统联网、启动telnet、SSH2，具体操作留存

ubuntu下gns3实验5：7200启动ssh2

GNS3 Images: c7200-adventerprisek9_sna-mz.152-4.M8.image

cloud + C7200，7200插槽0为c7200-io-2fe

cloud config:

NIO Ethernet -> 选择vmnet1 【vmware虚拟机的虚拟网卡】

7200 config:

conf t

inte f0/0

ip address 192.168.81.4 255.255.255.0

no shutdown

ip route 0.0.0.0 0.0.0.0 192.168.81.1

wr

ping 192.168.81.147 ok

添加telnet远程登录用户:

(config)#aaa new-model

(config)#username test privilege 15 password test

(config)#line vty 0 4

(config-line)#transport input ssh telnet

从虚拟机中telnet可以访问，OK

(config)#hostname test

(config)#ip domain-name 7200.com

(config)#crypto key generate rsa

(config)#ip ssh version 2

(config)#ip ssh pubkey-chian

(config-ssh-pubkey)#username test

(config-ssh-pubkey-user)#key-string

(config)#end

#wr

test#show ip ssh

SSH Enabled - version 2.0

Authentication timeout: 120 secs; Authentication retries: 3

Minimum expected Diffie Hellman key size : 1024 bits

IOS Keys in SECSH format(ssh-rsa, base64 encoded):

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAAAgQDLG2ZOB7sEoZdfEWjp/a4+BICOdDjg+mM0nz+mitea

从虚拟机中SSH test@192.168.81.4 OK

如果只想SSH连接：

(config)#line vty 0 4

(config-line)#transport input ssh

如果只想telnet连接：

(config)#line vty 0 4

(config-line)#transport input telnet
