a) Is ~/.ssh/known_hosts or ~/.ssh/authorized_keys where cached secure shell encryption keys from other systems that the user has contacted in the past are stored?
b) What file must I edit to configure the settings used by the secure shell daemon ?
Customer is running LMS 2.6.Scheduled backup was running perfect. But it is no more happening.When we checked we found that the "License Manager/ Deamon Manager is down" message pop ups.
We reset the casuser password, and then restarted the services. It becomes ok.But only the immediate backup is successful. Scheduled task fails for all those devices."License Manager/ Deamon Manager is down" happens quite often.

Here is the requirement.One shell profile with privelege 15 for IOS device admin and other one with different privelege for WCS admin.As there can't have two shell profiles on the same authroization profile, I created two different profiles, and match with the ACS local group name. However whenever user tries to access it always hits the 1st profiles.

I am trying to solve this problem without success so far. I have fresh ACS 4.2.15 patch 5 ACS installation and I am tryng to deploy it to our environment. So I have configured one 2960S to be my test client and everything works fine. Problem is when I try to create fine grained policies using network device groups and shell authorization sets.
I have created shell authorization sets called ReadOnly and FullAccess. I have also created NDG called FloorSwitches and added my 2960. I have 2 user groups called FloorSwitchesReadOnly and FloorSwithcesFullAccess. Now, if I configure group FloorSwitchesFullAccess and assign Shell command authorization set per NDG and then log into the switch, all of my commands are refused as unauthorized.
One thing that I have noticed is that if I assign shell command authorization set to any device ( in user group settings ) it works fine. Or if I create association with DEFAULT NDG in user group it also works. So my conclusion is that ACS for some reason does not associate my switch with correct group but rather puts it to DEFAULT group for some reason.
Currently i deploy a ACS 5.3 at customer site. The issue i face currently is some command sets not able to deny. Example like below:
i want to deny the AD user with priviledge level 15 to change the enable secret password and delete the enable secret password.

How to link the command set to a shell profile in acs 5.2.
View 1 Replies View RelatedI am in the process of setting up ACS 5.2 for a network and have run into an issue when attempting to apply the following aaa commands to a network device:
aaa authorization exec default group tacacs+ local if-authenticated
aaa authorization commands 1 default group tacacs+ if-authenticated
aaa authorization commands 15 default group tacacs+ local if-authenticated
Once the commands have been applied to the device configuration I get "command authorization failed" when attempting to do anything. Taking a quick look at the TACACS Authorization reports I see a failure reason of "13025 Command failed to match a Permit rule" and under the Selected Command Set "Deny All Commands" is listed. After doing a bit of searching, I noticed some articles online that indicate I should be able to specify the appropriate command set to the authorization profile under the Default Device Admin policy. However, when I open up a Device Administration Authorization Policy, nowhere in the window does it display command sets that I can select from.
I'm trying to configure a shell commnds set such that all commands (including under conf t mode) will be allowed, except for administrative commands, such as write, copy, admin, format etc.It's been working for (most) priviliged mode commands (such as write and copy) but has been unsuccessful for any command under conf t mode. It's important in order to prevent the users from performing 'do write' and 'do copy run start' commands, for example.Here's the input of the shell command authorization set (Partial_access):
Unmatched Commands: permit
Command list:
admin
copy
delete
do

This question might actually belong under tacacs server but it's only happening with the ACE. I've configured tacacs on the 4710 and configured the tacacs server per the documentation. If I enter the shell:<context>*Admin default-domain under the group settings when I login with my tacacs ID my role is set to Network-Monitor. If I set the shell in my specific tacacs ID I'm assigned the correct role as Admin. We're running ACS ver 4.1 and the ACE is A4(1.1)

I have two Nexus 5520 running 5.0(3)N1(1c).
I have both boxes heading off to ACS for TACACS lo gin authentication and for command authorization. When I first set things up everything works fine. I have a shell profile configured in ACS with Cisco-av-pair*shell:roles="network-admin" to set the network-admin role. I even have command sets configured to deny the use of configure terminal as I am using switch configuration profiles. Everything runs fine. User lo gins are authenticated by ACS and users have the correct command set applied to them.
The problem comes when I make a change to a shell profile in ACS. Even something as simple as changing the name of a shell profile causes the 5520's to crash as soon as I try to log on. If I unplug the management link so that the TACACS server is unavailable I can log on fine with the local admin user.
The NEXUS console reports this error. (amongst many others)

Could this be a bug with Nexus/ACS?
I'm using Fedora 15, in GNOME Shell, my mobile broadband connection was working absolutely fine, until I set the connection type to Connect Automatically using nm-connection-manager. Now, when I start the Fedora, the Top panel network icon shows red exclamation symbol and when I click it, instead of showing me available networks' list, it shows only "Network Settings", and when I open it, it shows GNOME 3's new Network Manager app, and it pops out the dialog saying that, "Current network settings service is incompatible with this version". And after a few seconds of log in, the shell freezes and all I can do is log out using Ctrl+Alt+BackSpace.
I'm facing this problem since I opened old network manager app using nm-connection-manager in the run dialog, and editing my connection to connect automatically.
After logging in to the shell I somehow managed to delete that connection from the same app and created a new one, but the problem still exists. How can I delete all network preferences (by deleting its configuration files from my home directory or something like that) and reset the GNOME 3's network manager to its default state?

View 2 Replies View Relatedhow IPSEC VPN works but i hit a stumbling block understanding symmetric encryption keys.Here is my understanding about the process
1.Peers will negotiate plocies
2.Authenticate using pre-shared or certificates
3.Exchange DH Public Keys
4.Using Public keys encrypt symmetric key and exchange the same key which will be useful for communication
5.maintain sessions
But when we are configuring we will define encryption keys in isakmp phase and ipsec transform set ,i thought we will use the same encryption key for both management and data communication in fact i thought management phase is to give us a securely exchanged encryption key for the data tunnel.But we can use 2 different encryption keys in 2 phase i am bit confused.

View 1 Replies View RelatedI have a Cisco 877 router and I configured it to act as a VPN server, supporting both PPTP and L2TP VPNs. I can succesfully connect to it from Windows computers using the built-in VPN software.There is only one problem: when using a PPTP VPN, encryption doesn't work. If I configure the client to require encryption (default setting), the connection fails with an error about the remote endpoint not supporting it. If I remove the encryption requirement, the connection succeeds. I've also tried tweaking the encryption settings (40/128 bits), but this didn't work either. [code]
The router's IOS version is 15, and it fully supports encryption. The strangest thing is, encryption is actually required in the router config; but not only the router doesn't seem to offer it... it also accepts unencrypted connections, which it shouldn't. It's like the ppp encrypt mppe auto required command is completely ignored.
I've some VPN encryption method questions.Is it recommended to use different encryption algorithms for both VPN phases (phase 1 and phase 2)?I’ve read once that it is much secure to use different encryption algorithms for each phase.In my opinion, I would go for the AES256 algorithm in both phases. But maybe it is a better idea to use AES128 or AES192 in the first phase and AES-256 in the second phase… I don't know.After saying this, I’m also wondering about the best VPN encryption setup for a site-to-site VPN (IKEv2) when using a Cisco ASA like the 5510, 5520 or the 5515.Which encryption method is recommended for phase 1 and phase 2Which PFS / DH-group should be used (considering CPU load and security)
