I am using a Cisco 2801 Router and currently have Telnet enabled on all interfaces. How do I change that so it is enabled from all inside networks, but not on the outside interface?

i tried no telnet alone it wont work as i didnt configured any telnet at all.
I setup a site-to-site VPN tunnel at the remote ASA5505. I am able to asdm to the outside interface but not ssh. I switch to telnet and still not allow me to access. I added an ACL to allow telnet any to the outside interface but still not working. In ASDM I see the log Here is the second issue. When I want to change the telnet back to ssh using ASDM I got the following error.

the intent of the above is that management connections will only be accepted via SSH, and all of those will be authenticated via RADIUS, unless it's down, then it will use the local username/pw combinations, most of which are given Privledge level 15. Telnet should never work.SSH works as expected (authenticates via RADIUS), but the problem is that Telnet also works, will ONLY use the local database (never RADIUS), and, for some reason, leaves the users at Privledge level 1, instead of the configured 15.Essentially, it seems that at every point I have told it to do something that isn't the default with regards to telnet, it ignores me.Prior to a recent IOS upgrade, the switch didn't support SSH, so the previous config was Telnet with RADIUS, and that worked fine.
disable telnet for ACS 1120 Appliance version 5.0.0.21 .is there anway to do it , not able to login via telnet and ssh it says wrong credentials but webgui is working fine with same user and password.

In have a cisco 2801 router, fast 0/0 - internal network and fast 0/1 - internet
I have packets coming into fast 0/0 with dscp values ef, cs3, cs5, etc ... going the the internet thru fast 0/1. I only have basic configuration on fast 0/1 - no service-policy, no class-map, configured
Scenario: packets with dscp values arriving in fast 0/0 will exit fast 0/1 to the internet.
Question: Will these packets will be tagged the same dscp values when they exit to the internet?
Is this true or do I have make some configuration changes at my end to have this scenario configured.

I have one problem doing a ping to a router lan interface, I have 3 routers (2801) connected between each other (separated 1 mile each), the link is established trough microwave signals (connected to the 2801 fast ethernet interfaces), every router has a connection to a LAN. One of them is located at headquarters.Last thursday I replace one of the router with a cisco 2901, i configure the router with the same configuration that was on the 2801, i power up the router and the 2 link were up without problems.One day after the noc called me to tell me that after i replace the router they can't ping the router IP lan interface on the new 2901 (before the replacement the ping was sucessful). I called one user the lan connected to that 2901, and they can do a ping to the router's LAN IP address.
I can ping the 2901 IP wan interfaces, I can ping the LAN users ip address, but i cannot ping the router LAN IP address, from my desktop, and neither the 2 routers 2801 connected to the 2901.I show the configuration on the 2901, I couldn't change it because i didn't have time to do that, but i'll change the configuration to use ipsec tunnels.The configuration as you can see, has a crypto map, but the acl used by the crypto map, only permits the interfaces ip address, so i think that doesn't work, so the traffic doesn't get encrypted, but i don't know if that is the problem why i can't do a ping to the lan interface.

I have Cisco router 851 at my region site. It has five Fa ports. One of them is connected to ISP and has ip address 10.1.1.2 (for example). It also has vlan 1 interface, that has ip address 192.168.0.1 (also for example). I also have Tun0 interface that goes through ISP network and connects to my hub network. The rest of Fa interfaces are swithcable and they are in vlan 1.The problem is that from hub LAN I can telnet to 10.1.1.2 ip address, but I can't telnet to 192.168.0.1. Whereas I can Ping 192.168.0.1 from my hub LAN.

I recently configured a Cisco AP 1242, software version 12.4, via the web interface using the default Cisco credentials. At that time I setup an administrator account with read/write access and changed the Cisco to a read only access. Now went I attempt to login to the web interface it won't accept the administrator password. It will except the administrator password in a telnet session however. So via the telnet session I setup another user with privileged exec level access and that wont work on the web interface either. The Login box keeps coming back requesting a password. Strangely enough, I can login to the web Interface using admin username, with the Cisco password; but I can't do anything, and I also can't view everything. I've tried the following:
I've turned on SSH and created a certificate in the AP, but the login box continues to pop on the https://url.I've attempted to setup a user with a non-encrypted password, but have been unsuccessful.I've tried a different browser - login box continues to pop.I've made sure the web interface is activated in the API've tried a differnet computerI've tried disabling password-encryption service. Reset the enable password , I've successfully setup other 1240 APs but must have done something wrong on this one.
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 tried connecting from the PC's serial port to the units console port using Cisco's blue cable with no avail. All I get is a cursor but no response. I've tried using 9600,8,none,1,none as settings and I can sucessfully console a Cisco 1700 router with those same settings in Putty no problem, but it doesn't work with this Pix. I've also tried using other possible common speeds like 1200,1400,4800,19200, 38400, 57600 and 115200 in case the firewall was set to use those and that didn't work either.

I have a cisco asa 5520. i need to forward telnet to a router on the inside interface. Here is what i have done so far but it doesnt seem to be working.
I have created an access-list that looks like this:
access-list 102 extended permit tcp any host 10.10.60.2 eq telnet
But when do this it still doesnt forward my request to the router at 10.10.60.2 . So just to explain what im trying to do. I use Putty, i am putting the outside interface IP into putty, selecting telnet and opening the session. i need the outside interface to see this request and know to forward port 23 to the router on the inside interface with IP 10.10.60.2. The ASA is running version: asa842-k8.bin
I got 2 x 5520 ASAs configured in active/standby mode and they are connected to 2 x 4500 switches in which too configured for failover.Telnet to ASAs is allowed only via subnet 172.18.0.0./24
I can only ping and telnet to the active ASA from subnet 172.18.0.0./24 but not the standby But i can ping and telnet to both the active and standby ASAs within the 4500 switches.
I have very strange behaviour on my Cisco 2801 router when I applied access list on wan interface.
Architecture:
SIP Provider <----> Cisco 2801 <-----> CUCM 6
Problem:
We are using Cisco 2801 as Voice gateway for CUCM 6. so only one purpose of this router is just receiving calls on sip dial-peer and transfering to internal network.
If you look on access list below, if 'log' words don't present on these 2 lines, access list didn't work. Problem with it is that when I establish call from us or to us I can't hear incomming RPT stream, but other side can hear me. But when I type word 'log' there, everything stars working immediately.
