Cisco Security :: 871 - Ssh Not Working
Nov 2, 2011
I am setting up ssh on my 871 router and I get prompted for only a password. I have typed in the correct password and it doesnt let me in. I also have telnet enabled and with telnet I do get prompted for both username and password and I am able to login. I would like to setup ssh so that it used the local username and password. This is what my vty has.
line vty 0 4
access-class 23 in
privilege level 15
login
transport input telnet ssh

I am trying to get a NAC demo running and am having some issues with a Layer 2 OOB, Virtual GW configuration. Currently I have 3560G switches and would like to assign ports to a vlan based on user roles.
My Auth VLAN is 110 and maps to VLAN 11
Guest VLAN is 11 (172.16.1.0/24)
Employee VLAN is 1
NAS Mgmt VLAN is 20 - CAS is 10.10.20.5 (this ip is setup on both eth0 and eth1 per documentation for L2 OOB Virtual GW)
NAM Mgmt VLAN is 30 - CAM is 10.10.30.5
Untrusted (Eth1) switchport is setup as a trunk allowing only vlan 110 and has a native vlan 999 to blackhole traffic.
Trusted (Eth0) switchport is setup as a trunk allowing vlan 1, 11, 20 and has a native vlan 998 to blackhole traffic.
I also setup a Managed Subnet on the CAS with IP 172.16.1.254 and VLAN 110.Switchport controlled by NAC is access vlan 110. When a machine connects an snmp trap is sent to CAM and is forced into vlan 110. If I try to put the port in another vlan CAM puts it back to 110 immediately. This all seems to be working well.The machine connected to the port gets a DHCP address from VLAN 11. When I initiate traffic from this machine, everything is blocked. If I open a web browser I do not get an authentication page. I also installed CCA 4.1.10 on the machine but it does not find a discovery host and the Login option is grayed out. The only way to get this machine to send traffic is to add a filter for it and force it to the ALLOW option. I did setup a default web login page but I seem to be missing something to get authentication to work. I am running version 4.1.8 with a demo license. The host running CCA is Windows Vista.

what the problem is with the "Call returned Connection time out for update testlab831.xxxxxx.com <=>" line.

A N600 Router Model F9J1102v1 router first installed in July 2012 with WPA-PSK, MAC Address Filtering and "Self Healing" enabled would not allow a new PC to connect via an RJ45 port. Belkin support ask for the unit to be reset to factory settings which is done and the Security system re-enabled again. Valid MAC Addresses start to be added and midway a PC is discovered in the Network without its MAC address added. Closer scrutiny reveals that another unknown device has also found a way into the router and that the 'Block' option on the MAC list is also failing to work. Anyone think of what one should do with this security shambles other than turn the thing off quick?

Just got a new router. All of my devices connect fine to it except for the desktop that is using an external Linksys wireless adapter (WUSB54AG).The desktop is running Windows XP (Home Edition) SP3.The latest driver for the adapter has been installed (3.0.18.0).I am able to connect if security on the router is turned OFF.The router has 3 security options:
1) WPA-PSK (TKIP)
2) WPA2-PSK (AES)
3) WPA-PSk (TKIP) + WPA2-PSK (AES)
My understanding (from Linksys tech support) is that the device SHOULD be able to connect using WPA-PSK (TKIP). My Linksys Monitor indicates that the device is connected to the access point but not the internet (when I used WPA-PSK (TKIP). The IP address that is assigned is 169.254.3.129 and not the expected 192.168.1.x.When I turn security OFF on the router, the device can connect and I am assigned a "good" IP address (192.168.1.x).

I have a WRT610N (v2) router and I recently updated the firmware to the most current version 2.00.01 build 15. I can no longer set WPA2 security for both bands (used to work just fine). Every time I try to save settings for WPA2 for the 5 GHz band, it tells me it was successful but then displays that the security mode is disabled (and it shows up on my computers list as not having any security enabled. If not, where can I get a copy of the old firmware that worked?

I have a Linksys WRT610N wireless system with WPA-PSK security and this works fine with several computers but now one computer detects the wireless security as WEP and can thus not connect to the router. I have tried to manually connect to the router with correct security WPA-Personal (TKIP) and correct password but then the computer says "settings saved on this computer for the network do not match the requirements of the network".How can I get the computer to detect the correct security? The computer is running Windows 7 home premium.

Is it true that the FCC is investigating the Pogo game site because of poor security? Is Java the cause of this problem?I'm very leery of getting on the Pogo site because I've been told that my computer could get a virus and crash.

I'm new to IT, and have been put in charge of managing our servers hile my boss is on vacation.We currently have a Sonicwall Network Security Appliance that handles our Firewall/VPN and have web content filtering set in place.I have a user who belongs to 2 CFS policy groups that we have set up. I've double checked with Active Directory, and he is a member of both groups.
This person SHOULD have access to Job searches/ and Restaurants,but receives a "content blocked" message on his browser.It appears to me that the settings in Sonicwall are correct, as well with AD member groups.

I was informed by a co-worker that there is a security vulnerability with the local certificate authority in the ASA running 8.3 code. I've looked through the security advisories and haven't been able to find anything about this. Was this just misquote or am I missing the security advisory release?

I have a ASA 5505 that I test with which originally came with the Security Plus license. I recently erased flash and loaded the latest asa841-k8.bin version of IOS along with asdm-642.bin. Everything booted fine and came up as it does when freshly wiped however I noticed that i was now only running a base license. If I issue the sh activiation-key command, I noticed the following messages (full output is at the bottom):
The Running Activation Key is not valid, using default setting
......
This platform has a Base license.
......
Failed to retrieve flash permanent activation key
Did I somehow kill my Security Plus licensing when I did the erase flash? If so how do I recover it?
ciscoasa# sh activation-key
Serial Number: JMXXXXXXHU
Running Permanent Activation Key: 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000
The Running Activation Key is not valid, using default settings:
Licensed features for this platform:
Maximum Physical Interfaces : 8 perpetual
VLANs : 3 DMZ Restricted
Dual ISPs : Disabled perpetual
VLAN Trunk Ports : 0 perpetual
[code]...
This platform has a Base license.Failed to retrieve flash permanent activation key.The flash permanent activation key is the SAME as the running permanent key.

ASUS Notebook G60Vx Series
Windows 7 Home Premium 64-bit
Intel(R) WiFi Link 5100 AGN
A few days ago my internet suddenly stopped working. I plugged in the ethernet cord and everything worked fine. Checking the properties in the device manager showed the device was working properly, I also tried resetting it to make sure it was enabled but it did not work.
Upon troubleshooting, the "Windows Network Diagnostic" said the problems was that the Wireless adapter was not turned on. Using the switch on the front of the laptop as well as the function keys does nothing. Usually a graphic pops up showing if the WiFi is on or off, changinging transparent to show the WiFi is disabled. Now when I turn the switch on it always appears transparent, effectively going from off to off
So I know the computer reads both the function keys and the switch on the front but both methods never actually turns the adapter on. I just finished a system restore and nothing has changed

Today, while surfing the web my internet connection on my PC just randomly shuts off. I go check on my laptop and its normal. My WiFi says that I am connected to an Unidentified network with no internet access. So i got frustrated and checked all the forums and nothing seemed to work. So i restored my computer to factory settings and I still got this problem. Does this mean my Wifi Card is bad? Is it a virus? I can see other networks fine but i just cant connect to mine!
