Cisco WAN :: Telnet Access Through Router 3925 Not Working?
Feb 18, 2013
i have 68 sites with Routers. On each site I have one equipment DIRECTLY connected to the Router that needs to be accessed by telnet port 23.
I have 15 off this sites that the access via telnet to the equipment’s connected after the routers are not working. These sites are using Router Cisco 3925. The other sites that are working are using Routers Cisco MWR 2921.
Both router models are running the same configuration with no filter on it.
The equipment’s after the routers are all accessed directly via telnet without the router. If the router is directly plugged to the equipment the 15 sites with Router Cisco 3925 are not accessed via telnet.
There is any bug related with the IOS version that Router Cisco 3925 is using?:
Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.1(2)T2, RELEASE SOFTWARE (fc1).ROM: System Bootstrap, Version 15.0(1r)M8, RELEASE SOFTWARE (fc1).System image file is "flash0:c3900-universalk9-mz.SPA.151-2.T2.bin"
I recently acquired a Cisco VPN 3000 Concentrator Series (fairly old hardware) without a manual, and I'm trying to figure out how to 'telnet' or browser into the router to access the IOS. The device has been reset and I am plugged into the console. I'm running Windows 7 and enabled the Win7 Telnet Client in the OS. Can any tell me how to do this or at least point me in the right direction to obtain the user manual for basic instructions?
Model number: CVPN3005-E/FE
I found the manual for it after going through some hyperlinks. But when you access the console in the Windows OS, is your network connection supposed to show disconnected, or connected but no internet access?
I'm trying to find out if there is anyway to enable telnet access on the WAG120n modem/router .I can't seem to be able to find related info in the support web site for this device. Any info if telnet is even available ?
I want to connect my clients from the Windows WS to a VPN Tunnel using 3925 router w/o Cisco VPN client. Is there the way to use native IPSec client on Windows XP or Windows 7?
implementation of the cisco CSS 11501 boxes available as spare on our site into production for an application evry thing worked as expected. i was able to telnet the active/master box and was able to console both master and backup box from the console port.however a week post the activity im faced with this weird problem where im not able to take console or the telnet access of my primary/active box.The boxes are working in BOX-to-BOX redundancy and now im not able to telnet or console my active/master box. The telnet and console window prompts me for username and password and after entering the credentials nothing happens. no prompt or no error message is displayed.
The telnet primary authentication is via tacacs and secondary is via local. however for console im not using any method for primay authentication and local for secondary authentication. however i can successfully console my backup box. below are my obsrvations 1. the left and right status LED on the active CSS box is OFF.- it means my CSS 11501 failed and has no power. 2. upon firing the rcmd command with show line command on backup box i see that the telnet sessions and console session is established with the master box3. the redundancy state of the active box says it is master and has not changed state since my last activity, no application issue reported, all the services are active on the active box and also i can ping the active box ip address from my backup box over which box to box redundancy is established. This confirms the active box is functioning well 4. i initially thought the telnet sessions are not getting cleared, however the show line cmd with the rcmd cmd on the backup box confirms this is not happening. now im stuck as the active box cannot be accessed at all via console or telnet. i was thinking of below steps to be carried out.1. to failover the boxes and make the backup as master2. then try to take the faulty box off the network and troubleshoot (are there any other commands that i should use to troubleshoot)3. if nothing works try rebooting the box and check
NOTE: the software running is version 7.20.30.3 with standard feature set. we are not using cvdm or the CSS GUI. we could access the css initially on CSS gui and that is also not working now.
I have a customer with a 861 ISR.I want to block all the privilege 0 users from access the enable command
If i telnet into the device, as a priv=0, enable does not work If i telnet into the device, as a priv=15, enable does work If i telnet into the device, as a priv=0, enable does not work If i telnet into the device, as a priv=15, enable does not work
I have issued the command:privilege exec level 15 enable Should block everyone except 15's from accessing the enable command SSH and TELNET are on the same vty:
line con 0 login authentication local_authen no modem enable line aux 0 line vty 0 3
[code]....
Basically TELNET is following the rules ( priv=0 not allowed to access enable ) but SSH is not following the rules ( both priv=15 and priv=0 cannot access the command ) is there a way from blocking somes users from login in completely?
I have a DCP 3925 with 2 telephone and 4 internet ports.So, how can I combine DPC 3925 + E3000 to have more internet ports? and wich one is the best wifi than I can use ??Main router is the DPC 3925, where the internet is connected.
I have configured the ip telnet source-interface Loopback 0 command on a Nexus7010, but when I telnet to another device and do a show users, the ip address is of the closest interface to the device I telnet to, not the ip address of the Loopback. All interfaces are in vrf default. I am running 5.1(6) NXOS.
I've set up this router in the office, and I can access it via PPTP without any problems from home (via windows VPN), Router is sat in DMZ with full access to the internet.
Q1,I've created a 2 phase ipsec vpn with an IKE & preshared key (AES/MD5/1), but I can't find out how to get my encrypted hash for it?also, I can't access the IOS via telnet/ putty, I found an article online explaining how to enable it via url string, but it didn't work,
Q2,I've setup the cisco client on my laptop, and working on the pcf file, without much luck.. Everytime I try to connect it get " error 412. the remote peer is no longer responding. " With wireshark, I can see the requests been made to the router.. ( from the office )
I have spend half day to look up this question in cisco official web site, but get nothing . Any infomation about vpn performance of 3925 router？Produce : cisco 3925 ( Cisco 3925 Security Bundle w/SEC license PAK )Question is , how much ipsec vpn tunnels can be carried as a vpn server of this bundle ? if more licenses may be bought, how much most tunnels can be held？
I try to access to WS-SVC-NAM-2 module in the Switch 6509. But is not work although the HTTP port is enabled (I tested with the command telnet @ip 80).
I try telnet access to the module to check the config , but I always the message that the lo gin / password is wrong even though they are valid.
We've got a SG200-18 switch that is to be used as a workgroup switch in our environment (SW Version 1.1.1.8). Working with CLI on big and mid-range Cisco-gear over the past two decades I'm having a hard time figuring out the following on the SG200:
o) I want to change the Management-VLAN from the default "1" to the management-VLAN used in our environment. Sure enough I created that vlan in the SG200-config, however when it comes to assigning the management-IP and VLAN for the management interface in the corresponding pulldown under "IPv4 interface -> Management VLAN" the only thing selectable is the default "1". (see screenshots enclosed)So how do I set a management VLAN different from 1?
o) How do I enable telnet/ssh-access to the SG200-18 - I'd be far more comfortable with a CLI-environment?
I want to remotely access Cisco 500 switches via TELNET and WEB BASED from a server. I dont know the ip addresses for Cisco 500 switches which are configured as backbone which the ip address assigned on the network is static ip address. Specifically I want to get their configuations inorder to get their specified assigned vlans on the network. I know the ip addresses for their specified cisco 500 switches' gateways. I know that cisco 500 switches can be accesses through web. Is there other ways to solve the problem apart from going onsite and connect to the cisco 500 switches using network cable since cisco 500 swithes dont have console ports?
We currently installed a 100Mbps fiber line with Ethernet hand-off. I purchased a Cisco 3925 ISR to be the gateway for this connection. I am not going to use it for any security purposes. I have an ASA5520 that will do that work. Right now I am currently just trying to get the router online.
I know the following
Laptop <--->GB 0/1((()))GB0/0<---->Ethern et handoff from ISP.
I can ping and SSH to the outside interface of the router from outside the network. I can also ping and SSH to the router from the laptop that is directly attached to the routers GB0/1 port. From the Router's CLI I can ping IP addresses on the internet. From the laptop I can not. I can not access the internet through the router though. Here is my config.Building configuration...

I have a network with 3 sites that are on different subnets. Each site has an ASA Right now, I am only able to connect to the ASA that is connected to the subnet I am connected to.I want to be able to connect to the ASA that are on the remote subnets on the address of the inside interface.The sites are connected all together by site-to-site VPN.Is there any way I can achieve that without opening the outside interface directly on the Internet?

In trying to make sure it was NOT wide open to the internet (amongst many other problems of setting it up, which I ,may address later if I can actually connect to the thing ever again) I told it to only accept connections from a range of address inside the LAN. Now it wont accept anything except telnet from the LAN.Short of wiping out 6 hours of trial and error configuration and resetting it, are there any other options I can exercise via the telnet interface?
I was trying to give the following host name to my 3925 router.Iht comes up with the following error. DRT0(config)#hostname DRT#0 % Hostname contains one or more illegal characters.% Hostname "DRT#0" is not a legal LAT node name, Using "CISCO_000000" DRT#0(config)#
Im going to change my NAT status to "open" on my xbox 360, but I don't have access to the router I think. Its my grandmas internet and im going to be here for 10 days so it could be nice if you could tell me the username and password so i can open the ports?
I was trying to enable AutoQoS on my router 3925 GE interfaces, but failed to do so !! But I was able to do so on FE interfaces !! I have Security/K9 and Data/K9 license on this router. Or do I still miss out anything ?? I am on IOS 150-1(M4).
I was able to enable AutoQoS on all my Cisco 2811 and 1841 routers !
I am facing an issue with a cisco 877 router. I am not able to telnet to this router from outside using the public IP. I have also notices this works when the Nat is removed.
