Cisco router + SSH ?
Does a Cisco router support SSH? How to configure?
Cisco routers support SSH. However, you need to have an IPSEC encryption image running on the router. Configuring SSH on a router is a simple process.
Use this link to configure SSH:

Not able to telnet or ssh to outside interface of ASA and Cisco Router
Dear All
Please help me with following question, I have set up testing lab, but still not work.
it is Hub and spoke site to site vpn case, connection between hub and spoke is metro-E, so we are using private ip for outside interface at each site.
Hub -- Juniper SRX
Spoke One - Cisco ASA with version 9.1(5)
spoke two - Cisco router with version 12.3
site to site vpn has been successful established. Customer would like to telnet/ssh to spoke's outside ip from Hub(using Hub's outside interface as source for telnet/ssh), or vise versa. Reason for setting up like this is they wants to be able to make configuration change even when site to site vpn is down. Sound like a easy job to do, I tried for a long time, search this forum and google too, but still not work.
Now I can successfully telnet/ssh to Hub SRX's outside interface from spoke (ASA has no telnet/ssh client, tested using Cisco router).
Anyone has ever done it before, please help to share your exp. Does Cisco ASA or router even support it?
When I tested it, of cause site to site vpn still up and running.
Thanks
YKHello YK,
On this case on the ASA, you should have the following:
CConfiguring Management Access Over a VPN Tunnel
If your VPN tunnel terminates on one interface, but you want to manage the ASA by accessing a different interface, you can identify that interface as a management-access interface. For example, if you enter the ASA from the outside interface, this feature lets you connect to the inside interface using ASDM, SSH, Telnet, or SNMP; or you can ping the inside interface when entering from the outside interface. Management access is available via the following VPN tunnel types: IPsec clients, IPsec LAN-to-LAN, and the AnyConnect SSL VPN client.
To specify an interface as a mangement-only interface, enter the following command:
hostname(config)# management access management_interface
where management_interface specifies the name of the management interface you want to access when entering the security appliance from another interface.
You can define only one management-access interface
Also make sure you have the pertinent configuration for SSH, telnet, ASDM and SNMP(if required), for a quick test you can enable on your lab Test:
SSH
- ssh 0 0 outside
- aaa authentication ssh console LOCAL
- Make sure you have a default RSA key, or create a new one either ways, with this command:
*crypto key generate rsa modulus 2048
Telnet
- telnet 0 0 outside
- aaa authentication telnet console LOCAL
Afterwards, if this works you can define the subnets that should be permitted.
On the router:
!--- Step 1: Configure the hostname if you have not previously done so.
hostname Router
!--- aaa new-model causes the local username and password on the router
!--- to be used in the absence of other AAA statements.
aaa new-model
username cisco password 0 cisco
!--- Step 2: Configure the router's DNS domain.
ip domain-name yourdomain.com
!--- Step 3: Generate an SSH key to be used with SSH.
crypto key generate rsa
ip ssh time-out 60
ip ssh authentication-retries 3
!--- Step 4: By default the vtys' transport is Telnet. In this case,
!--- Telnet and SSH is supported with transport input all
line vty 0 4
transport input All
*!--- Instead of aaa new-model, the login local command may be used.
no aaa new-model
line vty 0 4
login local
Let me know how it works out!
Please don't forget to Rate and mark as correct the helpful Post!

Cant ping behind cisco router (site2site vpn)
Dears;
After configure site to site vpn between cisco router and fortigate firewall,
site A : 10.0.0.0/24 behind fortigate
site B: 10.10.10.0/24 behind cisco router
the tunnel is up and I can ping 10.0.0.1 from site B and can ping 10.10.10.1 from site A but I cant ping any ip inside 10.0.0.0/24 form site B or network 10.10.10.0/24 from site A

ThanksHi David Castro,
Thanks for your answer,
I configed following your guide, but it have not worked yet. I saw that I cannot ping IP gateway Internet . I using ADSL Internet and config PPPoE and my router receive IP from ISP. Here show ip int brief :
GigabitEthernet0/0 192.168.1.1 YES NVRAM up up
GigabitEthernet0/1 unassigned YES NVRAM up up
GigabitEthernet0/2 unassigned YES NVRAM up up
Dialer1 210.245.54.49 YES IPCP up up
Dialer2 101.99.7.73 YES IPCP up up
NVI0 192.168.1.1 YES unset up up
Virtual-Access1 unassigned YES unset up up
Virtual-Access2 unassigned YES unset up up
Virtual-Access3 unassigned YES unset up up
But I cannot ping Interface Dialer 1, so may be VPN is does not worked. Do you have some ideal ?
Thanks very much ! -
How to arrive Password expiration situation in Cisco Router
Hi,
i have to test something on cisco router so i have to achieve this following scenario :-
I am trying to login using ssh username & passoword. so i need to expire this username & password on router.
Anybody tell me how to get this situation in my cisco router.
Thanks,
PranayPranay,
Here is a guide on configuring the SSH username and password on your Cisco device:
http://www.cisco.com/c/en/us/support/docs/security-vpn/secure-shell-ssh/4145-ssh.html
You will need to setup the VTY lines, as well as setup a password in order for this to work.
Judging from the screen shot, you will need to run the commands listed in Global Configuration mode. (configure terminal)
Example:
Router#config t
Router(config)# username Pranay priviledge 15 secret 0 yourpassword
I hope this helps. Please let me know if you need further assistance.

Management of integrated AP in Cisco Router 887
Hello!
I have a Cisco Router 887 here, with an integrated AP. This AP is a separate device in the router, with its own software, config, etc.
My problem I can't get the remote management of this AP to work (I'd prefer CLI, which means via SSH).
The router has a separate interface to communicate/manage with the AP:
interface wlan-ap0
description Service module interface to manage the embedded AP
ip unnumbered Vlan100
arp timeout 0
interface Vlan100
ip address 172.22.2.1 255.255.255.0
After this initial configuration, I can login to the AP *via the router* by issuing this command:
wlan service-module wlan-ap 0 session
When I'm on the router via console, this works! But when I'm on the router via SSH, it won't work:
router#connect 172.22.2.1 2002
Trying 172.22.2.1, 2002 ...
% Connections to that host not permitted from this terminal
I'd like to configure the access to work via an SSH-session also!
My line-configs are as follows:
line con 0
no modem enable
line aux 0
line 2
no activation-character
no exec
transport preferred none
transport input all
line vty 0 4
access-class VTY.TRUSTED in
exec-timeout 120 0
transport input ssh
I tried to remove the access-class and allow every protocol (transport input all), but it didn't change it. How can I make this access to work? How can I find out what is preventing it?
*Note: The rest of this posting covers technically a different problem! I would be very happy if i had at least an answer to one of the given problems!
After failing to achieve this, I tried to tackle the problem differently. This time by configuring an IP-Adress on the AP itself, to SSH directly to it. But I also couldn't get this to work!
There is an internal data-connection between router and the integrated AP:
router:
interface Wlan-GigabitEthernet0
description Internal switch interface connecting to the embedded AP
switchport mode trunk
no ip address
AP:
interface GigabitEthernet0
description the embedded AP GigabitEthernet 0 is an internal interface connecting AP with the host router
no ip address
bridge-group 1
bridge-group 1 spanning-disabled
no bridge-group 1 source-learning
interface GigabitEthernet0.100
encapsulation dot1Q 100
bridge-group 100
bridge-group 100 spanning-disabled
no bridge-group 100 source-learning
interface BVI100
ip address 172.22.2.5 255.255.255.0
bridge 100 route ip
The problem here is: I can't get the IP from BVI100 to work correctly in VLAN100. That is, I can't reach it anywhere from VLAN100. This happens in spite of the fact that the SSID (config not shown, it's a Dot11Radio0.100 subinterface with the corresponding bridge-group 100 attached) works perfectly fine.
In my tests I found if I configure the IP in BVI1 (Vlan1), it's reachable. Just in this case the VLAN 1 is not the VLAN I'd like the management IP to be.
Is there some additional bridge-group config missing? I wouldn't know which, as I see no difference to bridge-group 1, where it would work. The only difference is that VLAN 1 is bridged natively via the internal data-link, whereas VLAN 100 is tagged. As I said, WLAN over these SSIDs/VLANs works as expected.
Thanks,
FlorianOK thanks, I will look into that.
Do you perhaps also have an idea why I can't connect via the internal console port, if I have connected to the router previously via VTY?
router#wlan service-module wlan-ap 0 session
router#connect 172.22.2.1 2002
Trying 172.22.2.1, 2002 ...
% Connections to that host not permitted from this terminal
Thanks,

Send configuration file to Cisco router
Where can I find a C programm that send configuration file to Cisco router from linux workstation?
I wonder what kind of config changes you are making and whether that may have an impact on SSH. For example if you change the host name or change the domain name then the keys need to be regenerated.

Site-Site VPN PIX501 and CISCO Router
Hello Experts,
I'm having a test lab at home, I configure a site-to-site vpn using Cisco PIX501 and CISCO2691 router, for the configurations i just some links on the internet because my background on VPN configuration is not too well, for the routers configuration i follow this link:
www.firewall.cx/cisco-technical-knowledgebase/cisco-routers/867-cisco-router-site-to-site-ipsec-vpn.html
and for the pIX configuration I just use the VPN wizard of pix. Done all the confgurations but ping is unsuccessful. Hope you can help me with this, don't know what needs to be done here (Troubleshooting).
Attached here is my router's configuration, topology as well as the pix configuration. Hope you can help me w/ this. Thanks in advance.YES! IT FINALLY WORKS NOW! Here's the updated running-config

Configure a Cisco router with Username and Password.
Hello Guys,
Am quite new in cisco and i need to configure an 891 cisco router,can someone please show me step by step configuration commands for configuring Username and Secret Password.I would like the router to ask for "Username"and " Password" anytime i want to login the router through telnet.I also want to know if i have to erase the default configurations on the router first, before i start the configuration,and how it should be done in other not to loose the router whiles working on it.Thanks for your usual quick responds.
Regards,
Eben.Hello Eben,
Peter has suggested to use SSH because of the fact that telnet data is sent in clear text, so someone with the right tools could easily find your password and your device could/would be compromised. It is security best practice. SSH is encrypted.
Technically speaking you do not need to change the hostname / domain name. But majority of Cisco documentation follow this method.
In case you are interested on how to do this without change... see below.
Router(config)#
Router(config)#crypto key generate rsa modulus 1024
% Please define a hostname other than Router.
Router(config)#crypto key generate rsa modulus 1024 label CISCO
The name for the keys will be: CISCO
% The key modulus size is 1024 bits
% Generating 1024 bit RSA keys, keys will be non-exportable...[OK]
Router(config)#
*Jul 11 13:27:51.431: %SSH-5-ENABLED: SSH 1.99 has been enabled
Router(config)#
The normal cases just as shown in Cisco documentation, the parser (without a label on the crypto key) would force us to change the hostname, create a domain name. I think the domain name is there to put a label on the keys.
Router(config)#crypto key generate rsa general-keys modulus 1024
% Please define a hostname other than Router.
Router(config)#crypto key generate rsa
% Please define a hostname other than Router.
Router(config)#hos
Router(config)#hostname ISR
lexnetISR(config)#crypto key generate rsa general-keys modulus 1024
% Please define a domain-name first.
ISR(config)#ip domain name net.com
ISR(config)#exit
ISR(config)#crypto key generate rsa general-keys modulus 1024
The name for the keys will be: ISR.net.com
% The key modulus size is 1024 bits
% Generating 1024 bit RSA keys, keys will be non-exportable...[OK] -
Cisco Router tried to take a firmware update and no longer works
Ok so internet was working fine until Cisco Connect told me to take an update. My connection is wired and there were no disruptions during the download. Yet the download still failed and now my power light blinks continuously and there is no internet access. I tried instructions on "How to unbrick your Cisco Router", even got them to work, it took the firmware update from the cmd line. Still doesnt work though. What's wrong with this thing and how do i fix it?
Solved!
Go to Solution.I ended up downloading a firmware utility program and was able to get it to reload. The power light became solid somewhere between 2-5 mins, however still didnt connect to the internet. Found that all this factory resetting will change your Internet access name & password, with no way to find out the new one. You have to remove the Cisco Connect program from your computer and reload it from the original disk. Only then will you be up and running again. While I appreciate the response Helm, I was way beyond a 30 second reset button solution when I posted this lol.

Dear Sir ,
I am doing Remote Access VPN through Cisco Router. Before the real deployment, I want to simulate it with GNS3.Need you help to complete the job .Please see the attachment for Scenario, Configuration and Ping status.

I don't hve any NAT-exemptions in Cisco IOS Router. Transform-set I will change soon, but I've tried with tunnel mode and it didn't work.
Maybe NAT-exemptions is the issue. Can you advice me which exemptions should be in Cisco IOS Router?
Because on Cisco ASA I guess I have everything.

I have AppleTV and Ipad2 running VJay app to my TV over a private cisco router disabled firewall but I keep loosing the video on my TV after a few minutes what can I do?
I also get this problem on my iPad, so probably not related to the AppleTV. On the iPad I restarted Airport Extreme this time, and then the iPad saw my Home Sharing.
So to recap, restarting the router or Airport Express allowed the iPad and AppleTV to see Home Sharing. Restarting AppleTV also allows AppleTV to see Home Sharing.
So does anyone have any idea?
Thanks -
Do you need a cisco router at remote sites when using VRF BGP?
Hello.....
If you could refer to the attached document and read the following... I need to know if a CISCO router is required for each of the sites. OR does the ISP (Provider) provide the only required Router in the private cloud?
We want to replace the Cisco 891 with a PepLink but I don't know if we can do that. Can anyone jump in and help me understand?
When we hear about VRF, its almost synonymous to MPLS VPN. Virtual Routing and Forwarding is commonly used by Service Providers to provide services within an MPLS cloud with multiple customers. The most interesting feature of this is that, VRF allows creation of multiple routing tables within a single router. This means that overlapping use of IP addresses from different customers is possible. Some enterprises use VRF to seggrate their services like VOIP, wireless, geographical location and other varieties.Whether you can replace the 891 device with another device boils down to a single question: Do you need to run BGP with the Service Provider in order to use their service. If you need to run a routing protocol with your service provider, your service is likely a L3VPN (IP VPN) solution ( i.e. you inject your site's routes into the providers L3VPN session, they use MP-BGP+VRF for segmentation within their network).
If, however, they just drop you a L2 connection and provide L2 emulated services ( e.g. L2VPN or VPLS ) across their network, then your device can be whatever you want it to be.
From your device's perspective, it is not VRF aware. That is, it does not know about how the service provider segments your service from another customers. In the L3VPN case, your device is routing-protocol aware. In the L2VPN case, your device is not routing protocol aware and does not need to form adjacency with the service provider's equipment.

how to configure one dsl connection and one public ip in cisco router and map to one interface for using exchange server
Hi ,
Have you got any additional public IP Address from your service provider , If yes on router you can have static route for those additional IP Address pointing to your ASA outside interface .
Accordingly you can configure NAT
