Cisco AAA/Identity/Nac :: 3750 - IP HTTP Server (with No Authentication)
Dec 29, 2011
I have a customer who used to own a 3750 with a older version of IOS. The switch he had used a three year old version of IOS which allowed him to browse to the switch IP and manage it via HTTP without entering a password at all. Now that he has a replacement switch with a new ver of IOS (since the previous switch died). We slapped the config on from the old switch but no matter what we do (understanding that new http aaa authentication commands were added) we cant get this thing to let him in without prompting him for a password. I understand this was an insecure config to begin with so I shouldn't be advocating using it in the first place, but this is what the customer wants.Basically what I'm trying to figure out is are we banging our heads into the wall for nothing as the "ip http server" will not allow an authentication method of "none" anyway? None of the offical documentation I have read for the http aaa authentication cmds shows this as an example nor have I found any blog posts on how to do it ether. Perhaps Cisco removed this by design.
Here is the config:
aaa new model
aaa authentication login default local
aaa authentication enable default none
aaa authentication login none none
ip http server
ip http authentication aaa login-authentication none
I am trying to get AAA authentication for HTTP to use radius, and seem to be having problems with setting the priviledge level. It works fine with SSH login, but doesn't work with web management. The model is a WS-CBS3130X-S-F running 12.2(58)SE1 with http version 1.001.002...
Config is as follows:
aaa new-model aaa authentication login VTYSandHTTP group radius local aaa authorization exec VTYSandHTTP group radius local ip http server ip http authentication aaa login-authentication VTYSandHTTP
[code]...
This is what I get when I try to log on to HTTP
HTTP AAA Login-Authentication List name: VTYSandHTTP HTTP AAA Login-Authentication List name: VTYSandHTTP HTTP: Authentication failed for level 15
My switches are able to successfully authenticate user access against ACS 5.1 via SSH with TACACS+, but I am not able to authenticate via HTTPS with TACACS+. I don't even get a log in ACS when attempting to authenticate via HTTPS.
Here is my AAA config, followed by a debug:
aaa new-modelaaa authentication login ACCESS group tacacs+ localaaa authorization consoleaaa authorization config-commandsaaa authorization exec ACCESS group tacacs+ aaa authorization commands 1 Priv1 group tacacs+ none
I would like to make a centralized management of loggin account on my cisco switch (with a radius server). But, on Cisco 3750 E, i use 12.2(44) SE1 IOS and no command aaa authentication login exist.
Cisco 3750 can support other IOS than 12.2 who have this ability ?
I'm experiencing some problems with AAA authentication banners and banner logins.I'm trying to use spaces and empty lines, but when login, all the lines are after each other, no empty lines, no spaces.The problem appears on a 3750 with IOS version 12.2(5)SE2.
We are setting up a new office and I am trying to get RADIUS setup for authentication to my switches and routers. Currently I am working on a 3750 running IOS 15 and getting hung on what I think on something small. I have attached my Microsoft NPS Network Policy. Below is my IOS config:
aaa group server radius corp-radius server 10.15.10.20 auth-port 1812 acct-port 1813 ! aaa authentication login default group corp-radius local aaa authentication login radius-localfallback group corp-radius enable aaa authorization exec default group radius
We have a Catalyst 3750 switch that failed over to local login after the Tacacs authentication stopped working. I went through the configuration settings and everything appears to be identical to another switch in this same building.
1 ) : Is it possible to do authentication with one ACS server while authorization with another ACS? Use case is if the user authenticated to one ACS server and then switch loses the connectivity to this ACS. Now command authorization requests will go to another ACS server since switch is not able to communicate to the 1st ACS.
2): How can the local database sync be acheived in distributed ACS deployments?
3): Are the accounting records are sync between different ACS? In other words can accounting be centeralised with ACS4.2
We got 2 Cisco ACS 5.2.0.26.10.Primary server as authentication server and log collector.Secondary server as authentication server. Replication is configured. url..."There are some exceptions to this usual setup, which you can handle as described below: If the ACS 5.3 primary server also functions as a log collector in your 5.3 deployment, you should promote any one of the secondary servers as primary server in the deployment. See Promoting a Secondary Server to Primary "
This exception matches with my case. I have to promote my secondary server as primary.I would have :Secondary server as authentication server and log collector.Primary server as authentication server. I think I have to deregister secondary from primary server..According to the guide, I have to upgrade the log collector server. "Step 1: Choose any secondary server to become a log collector:" I dont have another secondary server..
Does Cisco Secure ACS 5.3 support LDAP authentication with Apple Mac OS X server? One of our clients require an access control system. The major portion of the network consists of Apple Mac OS X 10.7 (Lion) Server and clients. They were using MAC-address based authentication along with LDAP through Cisco Wireless LAN Controller. But now the number of users has exceeded the maximum number of MAC addresses supported by WLC (2048). Hence we suggested ACS appliance to overcome the limit. My doubt is whether ACS 5.3 appliance can communicate with the Mac server and perform LDAP authentication.
I've been configured my device 6506-9 with TACACS+ server authentication: [code]
but when I tried to access the device only uses authentication local but not uses TACACs (with username/password defined) it can be an error in configuration? in the other devices of network this works properly, only it's wrong in Cat6506-E
I installed NGS 2.0.2 for wireless guest user management and authentication. I implement webauth via webauth page on wlc deployed.One Branch with a WLC5508 version 7.0 wireless anchor controller is working on the NGS.But now I integrate next branch with WLC4402 version 6.0.188 and the authentication of users at the new branch gets an error, wrong user/password.
I double checked configuration and user/password but I can't find any configuration error. Also stopping and starting of radius service and reboot of NGS still does not work. I tried to debug the radius via web interface and watched for the loggfile and there is still a reject.I also tried the freeradius command radiusd -X but I got an error when starting the radiusd -X.
1.) How can I figure out, if I will get the correct password from my WLC ? Are there any debug options to see more ? e.g. some cli commands, radiustest utilities or how to get the received password from the chap challenge of the debug ?
2.) I have appended a part from my radius loggfile. How can I find the detailed error in the radius log file? Is it correct that the password in the debug file is empty ? raiuds logg line "[radius-user-auth] expand: %{User-Password} -> "
We have configured following commands on switch to fallback to local Vlan if both radius server (policy persona's) is found dead. For test purpose we shutdown both servers (policy persona's) but fallback didn't work. We have 3750 switch running image 12.2(55)SE6 having following configuration.We do not know whether we configured switch in proper way or do we need to modify it. [code]
I have follow below URL to disable the https over web authentication:
[URL]
What i want to achieve is disable https over web authentication due to certificate issue, but it seems like even we have disable the http over web management as above URL describe, still https while doing web authentication. Or it is possible to configure use port other than 80, like 8080 for web authentication? (need to reboot the wlc?)Is there any bug that related to this CSCsy32145?
We are using WLC 2500 and AP 1041 with web authentication. Due to we do not have the trusted/public certificate and want to get rid of the certificate warning during the user login. Is this possible to change the web authentication method from HTTPS to HTTP.
We have ASA 5520 as SSL VPN concentrator so users can access internal web from outside. Our internal web also has several internet URL. What we want is when user click internet URL in our internal web, ASA forward those request to internal proxy server. I already config proxy using port 8080 and username "companyuser" and password, but always have authentication failed on ssl vpn browser. We uses forefront TMG as proxy. Username and password have right to access Internet.
I have a strange problem in my ASA 5510 firewall. I turned on HTTP inspect policy to block certain URLs, but that destroyed svn communication. Interestingly, if I use simple web-browser to access svn server - it works, but any svn-client requests fail with an error "Could not read status line: An existing connection was forcibly closed by the remote host". I did some packet sniffing, and discovered that with HTTP inspect off the Webbed request is answered, but with HTTP inspect on it is rejected with an error unauthorized. Here are examples of success and failed conversation packets:
I found one mentioning of that error with that assessment: "Older firewall/proxies do not understand the Webbed related HTTP requests for accessing Subversion using HTTP{ URL} in that post But not any useful tips.
I am trying configure tacacs authentication for http in Cisco 2960 with IOS 15.0.1.SE. [code] But the device is not authenticating. It ask the credentials (user and pass) but not authenticates.
I have a web cache server, and I redirect all the HTTP request to it using WCCP.
Everything works without a problem, however I have a monitoring system that every minute tests the access to some customer sites that are hosted inside our infra-strutcture.
As soon as I configured the WCCP the monitoring system complains of timeouts accessing those sites, about 20% of the requests start to fail (timeout).
I don't think it is the fault of the cache because in the WCCP ACL I exclude all traffic that comes from my monitoring system. However as soon as I turn of WCCP the monitoring system never ever gives timeouts accessing those sites.
Is there anything I should do in WCCP to tweak it? I have WCCP configured in my core gateway that is a CISCO 3750.
I am facing issue with http login after IOS upgrade on 3750 switches. I upgrade IOS from c3750-ipbase-mz.122-35.SE5.bin to c3750-ipbase-mz.122-53.SE2. bin Any other command I have to run.
I have tried search but found found anything for the 3750 switch about how to redirect HTTP, HTTPS & SMTP traffic to altenative gateway, than our standard gateway on our network, so here goes:
The network that need the HTTP, HTTPS and SMTP traffic redirect is 192.168.5.0/24 and should be redirect to 192.168.5.205 where as all other traffic need to be direct to 192.168.5.199.
Can the 3750 switch do this typo of refirect and if how?? I cannot find anything on the Cisco site stating how or even if it is possible!
I am trying to mark http packets from a web server with DSCP ef, but when I am doing a traffic capture all http packets have tos 0x0.I am able to mark UDP and ICMP packets originated from this server, but not any TCP traffic.The web server is in VLAN 20This is my config mls qos ip access-list extended MARK-HTTP-ACL permit tcp host 10.10.10.10 eq www.

I configured before ACS v4.2 to authenticate network devices using internal users at first, and if the user is not found use AD list users. But with v5.3 I have some problems doing this, on identity policies I use rule based result selection option, I configured 2 polices for Identity source, one for Internal Users and other policy for AD user, but it only works with the first policy, internal users or AD, but works only for the first policy identity. how to do that, if the user is not found on first policy, continue to the next policy.
I need a specify users to allow access to particular devices and give privilege only for show command or show run. Here is how I tried to configured.
1. Configured two seperate Shell Profile and Command set with privilege level 4-5 and allowing only show run command
2. create seperate service selection rule with adding the require NDG and protocol TACACS and maching service "RestrictAccess"
3. In the RestrictAccess Service I have following configured; Identity: internal users, Group Mapping to a particular group where the user exists, authorization: matching the above created identity group, NDG, shell profile, command sets
All the steps are attached in the .doc file. However when I tried with the particular user he is able to access everything and he is not hitting the correct access rule.
In CLI we have users log in at priv 1 and use "enable" to increase privilege and do configurations. This allows "accounting" of command history. On the AIR-AP1121G-A-K9 (12.3(8)JED1) I cannot duplicate this for http login.
I can log in as a user at priv 1. When I try to go to a privileged link like "Security" I get prompted for a second login/pw. Nothing works here unless I have a second user defined at priv 15 and enter that login/pw. The problem is - that login/pw can be used to log in via http in the first place which bypasses accounting of the actual user. It also allows login to the CLI at priv 15 which I cannot permit.
i had done inter-vlan routing , attached a DNS server to that network, i didn knw how to config a server to act as http??? so that i can view webpages forn systems of that network??
we are having some trouble setting up our router (Cisco 861W) webserver on the LAN so that it can be accessed from outside (http via port 80). When we try to access it via the web address, we just get the login window of the Cisco router software?
I have one server-A(windows 2008) installed one application called"host front" which gives athentication to connect Linux(mainframe console)server(SERVER B). These 2 servers are bihind the firewall.If one internal user who has the athentication to logine server-B ,tried to login server A,will get the" username and password"screen and once they enter the username and password ,will get the server-B screen.But if somebody try to connet via MPLS(we need to test MPLS site customers) from outside via ASA 5540 ,to server-A will get the "username password" screen and once enter the credentials,after 1 minitue will get error"http server faild to send datas to the server" and will not move to server -B screen.Where do you think is the problem?
I just upgraded my ASA 5585 cluster from 8.2 to 8.4. I also upgraded the asdm .bin from 6.35 to 6.43. after rebooter the cluster, I try to access it with ASDM installed on my computer but it blocked at 17%.I tried to access [URL] but I just an error (with IE & FF) [code] What did I miss in the ocnfiguration ? I precise that I never used the http page, I already had the ASDM installed from another ASA.
I using IOS c2950-i6k2l2q4-mz.121-22.EA14.bin but no support command "ip http secure-server" and I not connect switch by CNA. How I fix ? Or IOS C2950 support ip http secure-server and ssh ver2 ?
