• Configure spanning tree from HP to Cisco hardware

  - by Tim Brigham

  I have three switches I'd like to configure in a loop - a Cisco stack (3750s) and two HP 2900 series. Each is connected to the next with a 10 gig backplane of one form or another. How do I configure the spanning tree on these systems to make this function correctly? From the documents I've looked at it looks like I need to set both sets of hardware to use MST mode but I'm not sure past that point. The trunking, etc is all set up as needed. HP Switch 1 A4 connected to Cisco 1/0/1. HP Switch 2 B2 connected to Cisco 2/0/1. HP Switch 1 A2 connected to HP Switch 2 A1. HP Switch 1 show spanning-tree Multiple Spanning Tree (MST) Information STP Enabled : Yes Force Version : MSTP-operation IST Mapped VLANs : 1-4094 Switch MAC Address : 0021f7-126580 Switch Priority : 32768 Max Age : 20 Max Hops : 20 Forward Delay : 15 Topology Change Count : 352,485 Time Since Last Change : 2 secs CST Root MAC Address : 0018ba-c74268 CST Root Priority : 1 CST Root Path Cost : 200000 CST Root Port : 1 IST Regional Root MAC Address : 0021f7-126580 IST Regional Root Priority : 32768 IST Regional Root Path Cost : 0 IST Remaining Hops : 20 Root Guard Ports : TCN Guard Ports : BPDU Protected Ports : BPDU Filtered Ports : PVST Protected Ports : PVST Filtered Ports : | Prio | Designated Hello Port Type | Cost rity State | Bridge Time PtP Edge ----- --------- + --------- ---- ---------- + ------------- ---- --- ---- ...

• Cisco VPN Connection - No internet no nothing

  - by Kevin

  Hi all, Sorry if this has been posted, I tried searching but I am not exactly sure what I am looking for, I am a developer not a networking guy. We have a client whom we need to use Cisco VPN client to connect to their servers. I have installed the software, dropped in the provided .pcf file, and I can connect. However, when I do, I lose all local and internet capabilities, no hosts resolve, and I still can't connect to their internal FTP and development sites. This leads me to believe either a setting is wrong in my Cisco software, and/or their network is not correctly configured. Does anyone know anything about Cisco VPN'ing that can give me a hand? My colleague seems to indicate that they need to enable split tunneling on their end (or a similar setting).

• Enable Cisco ASA as an SSH Tunneling

  - by Jim

  I am trying to utilize my Cisco ASA as a SSH Tunnel. I've configured this before when using a Linux server as the SSH target, however I cannot seem to get it to work with the ASA. I have configured and enabled SSH on the Cisco ASA, as well as a username that I can SSH to the console, however the SSH Tunneling feature does not work. For example, on my PC I use Putty with a Local Tunnel defined to a server behind the ASA. I should be able to (if SSH connected to the ASA) be able to access the server. See screenshot of putty. has anyone come across this before? Again this is to use my Cisco ASA as a SSH tunnel, this is not a port forwarding. -Jim

• No graphics after installing AMD Catalyst 12.4 and installing the recommended updates afterwards

  - by Innonic

  Some days ago, I installed Ubuntu 12.04. Since I wanted to use dualview using an external display I installed the propriatary AMD Catalyst 12.4. The graphics are fine, but if I run the updates found by the updates manager, Ubuntu won't be able to start with graphics after reboot. I installed Ubuntu 3 times until I realized what the problem was. So now I got the basic installation with Catalyst running but I can't update the system. Is there any solution to this? Or can I somehow identify which update causes this? My System is a Lenovo y560 Ideapad (Intel Core i7, 8GB RAM, with AMD Radeon HD 6570M/5700 Series. Thank you in advance

• Determining the health of a Cisco switch port?

  - by ewwhite

  I've been chasing a packet-loss and network stability issue for a handful of end-users on an internal network for the past few days... These issues surfaced recently, however, the location was struck by lightning six weeks ago. I was seeing 5-10% packet loss between a stack of four Cisco 2960's and several PC's and phones on the other side of a 77-meter run. The PC's were run inline with the phones over a trunked link. We were seeing dropped calls and interruptions in client-server applications and Microsoft Exchange connectivity. I tried the usual troubleshooting steps remotely, having a local technician do the following during breaks in user and production activity: change cables between the wall jack and device. change patch cables between the patch panel and switch port(s). try different switch ports within the 2960 stack. change end-user devices with known-good equipment (new phones, different PC's). clear switch port interface counters and monitor incrementing errors closely. (Pastebin output of sh int) Pored over the device logs and Observium RRD graphs. No link up/down issues from the switch side. change power strips on the end-user side. test cable runs from the Cisco 2960 using test cable-diagnostics tdr int Gi4/0/9 (clean)* test cable runs with a Tripp-Lite cable tester. (clean) run diagnostics on the switch stack members. (clean) In the end, it took three changes of switch ports to find a stable solution. The only logical conclusion is that a few Cisco 2960 switch ports are bad or flaky... Not dead, but not consistent in behavior either. I'm not used to seeing individual ports die in this manner. What else can I test or check to determine if these devices are bad? Is it common for single ports to have problems, rather than a contiguous bank of ports? BTW - show cable-diagnostics tdr int Gi4/0/14 is very cool...

• Cisco VPN stops Windows 7 Browsing

  - by Sharjeel Sayed

  My browsing and other 'internet' activity (dropbox,digsby etc) halts when I connect to my office VPN using Cisco Systems VPN client Version 5.0.04.0300 on my Windows 7 Ultimate.The only option left for me at this time is to use my office proxy to enable the connection back. I tried doing the ucheck "Use default gateway on remote network" solution as mentioned on a previous post Windows 7 VPN stops web browser but I don't see that option on the properties of "Cisco systems VPN adapter" connection properties.

• Cisco ASA Act as a Hardware Security Module?

  - by Derek

  Hello, We have a partner that is requiring us to get a HSM for a web application that we host for them. This is something new for us, we've always installed our SSL certificates on our web servers and never needed a hardware device. We currently have 2 Cisco ASA 5510 firewalls in an active/standby configuration. Both ASAs have a ASA-SSM-10 security module installed in them. The web application is a standard HTTPS webpage with no authentication required. I was wondering if we could use our Cisco ASAs to meet this requirement or if we'll have to buy another device. I was doing some searching and read about Cisco's clientless webvpn feature. It sounds like it might work, but I'm not sure. We basically want the ASA to handle the SSL and proxy the connection to our web servers. We do not want to prompt for a username or password to connect or show any portals, just display the web page. If the ASA cannot do this, does any one have any recommendations for network attached hardware security modules? We are using VMware vCenter, so we'd rather have an external device attached to the network, rather than buying HSM cards for every ESXi host. Thanks, Derek

• How to allow local LAN access while connected to Cisco VPN?

  - by Ian Boyd

  How can I maintain local LAN access while connected to Cisco VPN? When connecting using Cisco VPN, the server has to ability to instruct the client to prevent local LAN access. Assuming this server-side option cannot be turned off, how can allow local LAN access while connected with a Cisco VPN client? I used to think it was simply a matter of routes being added that capture LAN traffic with a higher metric, for example: Network Destination Netmask Gateway Interface Metric 10.0.0.0 255.255.0.0 10.0.0.3 10.0.0.3 20 <--Local LAN 10.0.0.0 255.255.0.0 192.168.199.1 192.168.199.12 1 <--VPN Link And trying to delete the 10.0.x.x -> 192.168.199.12 route don't have any effect: >route delete 10.0.0.0 >route delete 10.0.0.0 mask 255.255.0.0 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 if 192.168.199.12 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 if 0x3 And while it still might simply be a routing issue, attempts to add or delete routes fail. At what level is Cisco VPN client driver doing what in the networking stack that takes overrides a local administrator's ability to administer their machine? The Cisco VPN client cannot be employing magic. It's still software running on my computer. What mechanism is it using to interfere with my machine's network? What happens when an IP/ICMP packet arrives on the network? Where in the networking stack is the packet getting eaten? See also No internet connection with Cisco VPN Cisco VPN Client interrupts connectivity to my LDAP server Cisco VPN stops Windows 7 Browsing How can I prohibit the creation of a route in Windows XP upon connection to Cisco VPN?

Going forward, we can try to solve the same problem with their new client.

• iPad connections to Cisco VPN error -- "Enter your user authentication"

  - by rhart

  Is anyone else having problems with the iPad IPSec (Cisco) VPN configuration? I've configured a Cisco VPN connection to a PIX 501 firewall on a 32GB Wifi Apple iPad. This is done in Settings - General - Network - VPN - Add VPN Configuration - IPSec tab. When everything is set up properly and I attempt to connect I just get a popup that says "Enter your user authentication" with no fields to enter either piece of info, and just OK and Cancel buttons. I've read about similar problems with the VPN client built into Mac OS X and the iPhone 3GS but never with the iPad. Does anybody know a solution? I'm not afraid to change the configuration of my PIX 501 if that's necessary.

• Cisco ASA bonding/teaming/port-channel capabilities

  - by Antoine Benkemoun

  Hello, This seemed to me like a really simple question that I would be able to answer by myself but I have not been able to find any info on this subject. I have a Cisco ASA 5510 which has 4 FastEthernet interfaces. I was wondering if it would be possible to use 2 or 3 of these interfaces as a port-channel in order to agregate bandwidth for multiple VLANs. I have found no info on the Cisco website nor on Google. Is this just a stupid/crazy idea or am I missing something ? Thank you in advance for your help, Antoine

• Cisco 877 as a VPN server?

  - by Massimo

  I have a Cisco 877 router which connects my network to the Internet using an ADSL line, a single public IP address and NAT; the IOS version is 15. Everything is working ok, but I'd like to configure this router to be a VPN server, to be able to connect to the network from the outside. I've tried looking for documentation, but everything I can find is related to having the 877 act as a VPN client, or to site-to-site VPNs; I can't find anything about letting single remote computers access the internal network, which is something I can do quite easily using Windows' RRAS or ISA Server. Can the Cisco 877 act as a VPN server for remote client computers? (Looks like it should, but just to be sure...) Which type of VPNs does it support? Do they require some special software on the client machines, or can they be used by standard out-of-the-box Windows computers? And, finally: how to set up this?

• Stop Cisco AnyConnect from locking down the NIC

  - by Johannes Rössel

  Cisco's VPN crapclients (including the AnyConnect one) have the nasty habit of clobbering all NICs on the system you're using them. The old client had a checkbox in the connection options that allowed you to use other network interfaces while being connected while the AnyConnect client doesn't have any options at all, seemingly. But they both lock down the network interface they are using to connect to the VPN. Since I am forced to use AnyConnect to actually have an internet connection and I like to control a second computer at home via RDP (over the same network interface so far) this doesn't quite work out. With the old client IPv6 still worked just fine, though AnyConnect seems to dislike that as well now. Is there any way to still use the same network interface for LAN access? I actually don't really care about any possible security implications (which might be why Cisco does this) as it's my freaking internet connection and not a secure way of working from home. The trade-off is quite different :-)

• Cisco WebVPN RDP Plugin and NLA

  - by bab

  I'm having trouble finding anything in Cisco's docs or with Google searches, so I'm hoping someone out in ServerFault land might know. We've recently enabled NLA domain-wide to protect against some of the recent RDP vulnerabilities. However, we can no longer use the Cisco WebVPN on our ASA to connect to these boxes (Connection Failure). I assume this is because the RDP2 plugin (as of Apr 27 2012) doesn't support NLA? Is there another version of the plugin that does? Thanks!

• Quickbooks and Cisco ASA 5505

  - by user41516

  I have a Cisco ASA 5505, and everything has seemed to function fine, however I have had problems with Quickbooks 2008 running super slow over the network (Samba) and narrowed it down to the Cisco box. Other Samba transfers seem to be pretty fast, and the Quickbooks file is not very large at all (<25 MB), and other Samba transfers seem to be fine. However, I'm not sure if Quickbooks uses another protocol or if there are other ports that need to be opened. Can anybody give me any clues on how to resolve or troubleshoot the problem or have any prior experience with running Quickbooks over a network?

• Cisco ASA not forwarding traffic from one interface to another

  - by Antoine Benkemoun

  Hello ServerFault, I am needing help in the configuration process of my Cisco ASA 5510. I have set up 4 Cisco ASA interconnected together via a big LAN. Each Cisco ASA has 3 or 4 LANs attached to them. The IP routing part is taken care of by OSPF. My problem is on another level. A computer connected to one of the LANs attached to an ASA has no problem communicating with the outside world. The outside world being anything "after" the ASA. My problem is that I am completely unable to have them communicate with another LAN connected to the same ASA. To rephrase this, I am unable to send traffic from one interface of a given ASA to another interface of the same ASA. My configuration is the following : ! hostname Fuji ! interface Ethernet0/0 speed 100 duplex full nameif outside security-level 0 ip address 10.0.0.2 255.255.255.0 no shutdown ! interface Ethernet0/1 speed 100 duplex full nameif cs4 no shutdown security-level 100 ip address 10.1.4.1 255.255.255.0 ! interface Ethernet0/2 speed 100 duplex full no shutdown ! interface Ethernet0/2.15 vlan 15 nameif cs5 security-level 100 ip address 10.1.5.1 255.255.255.0 ! interface Ethernet0/2.16 vlan 16 nameif cs6 security-level 100 ip address 10.1.6.1 255.255.255.0 ! interface Management0/0 speed 100 duplex full nameif management security-level 100 ip address 10.6.0.252 255.255.255.0 ! access-list nat_cs4 extended permit ip 10.1.4.0 255.255.255.0 any access-list acl_cs4 extended permit ip 10.1.4.0 255.255.255.0 any access-list nat_cs5 extended permit ip 10.1.5.0 255.255.255.0 any access-list acl_cs5 extended permit ip 10.1.5.0 255.255.255.0 any access-list nat_cs6 extended permit ip 10.1.6.0 255.255.255.0 any access-list acl_cs6 extended permit ip 10.1.6.0 255.255.255.0 any ! access-list nat_outside extended permit ip any any access-list acl_outside extended permit ip any 10.1.4.0 255.255.255.0 access-list acl_outside extended permit ip any 10.1.5.0 255.255.255.0 access-list acl_outside extended permit ip any 10.1.6.0 255.255.255.0 ! nat (outside) 0 access-list nat_outside nat (cs4) 0 access-list nat_cs4 nat (cs5) 0 access-list nat_cs5 nat (cs6) 0 access-list nat_cs6 ! static (outside,cs4) 0.0.0.0 0.0.0.0 netmask 0.0.0.0 static (outside,cs5) 0.0.0.0 0.0.0.0 netmask 0.0.0.0 static (outside,cs6) 0.0.0.0 0.0.0.0 netmask 0.0.0.0 ! static (cs4,outside) 10.1.4.0 10.1.4.0 netmask 255.255.255.0 static (cs4,cs5) 10.1.4.0 10.1.4.0 netmask 255.255.255.0 static (cs4,cs6) 10.1.4.0 10.1.4.0 netmask 255.255.255.0 ! static (cs5,outside) 10.1.5.0 10.1.5.0 netmask 255.255.255.0 static (cs5,cs4) 10.1.5.0 10.1.5.0 netmask 255.255.255.0 static (cs5,cs6) 10.1.5.0 10.1.5.0 netmask 255.255.255.0 ! static (cs6,outside) 10.1.6.0 10.1.6.0 netmask 255.255.255.0 static (cs6,cs4) 10.1.6.0 10.1.6.0 netmask 255.255.255.0 static (cs6,cs5) 10.1.6.0 10.1.6.0 netmask 255.255.255.0 ! access-group acl_outside in interface outside access-group acl_cs4 in interface cs4 access-group acl_cs5 in interface cs5 access-group acl_cs6 in interface cs6 ! router ospf 1 network 10.0.0.0 255.255.255.0 area 1 network 10.1.4.0 255.255.255.0 area 1 network 10.1.5.0 255.255.255.0 area 1 network 10.1.6.0 255.255.255.0 area 1 log-adj-changes ! There is nothing really complicated in this configuration. It just NATs from one interface to another and that's it. I have tried enabling same-security-traffic permit inter-interface but that doesn't help. I therefore must be missing something a little bit more complicated. Does anyone know why I cannot foward traffic from one interface to another ? Thank you in advance for your help, Antoine

  I am hoping someone here can help me with my problem. I am trying to setup an IPSEC site-to-site VPN between two cisco ASA 5520's in GNS3 (both using 8.4.2). I have been unsuccesful in getting the tunnel up and it appears neither ASA is sending packets out,in regards to phase 1 and phase 2 (tested by using wireshark and seeing NO udp 500 packets). Doing show ipsec sa and such shows nothing. CALIFORNIA(config)# show ipsec sa There are no ipsec sas FLA-ASA# show ipsec sa There are no ipsec sas I will attach both configurations in two different pastebin files as to keep this post a bit cleaner. Essentially California side has 172.20.1.0/24 and Florida side has 10.10.10.0/24. California ASA config: http://pastebin.com/v0pngYzF Florida ASA config: http://pastebin.com/E2geybta Please let me know if there is any other vital information that could help. I have gotten IPSEC tunnels to work using openSwan (linux) and cisco routers but cannot for the life of me get ASA IPSEC tunnels to work. The ASDM is out of the question I only use cli. Thanks for any useful help!

• ATI Catalyst doesn't retain changes after reboot when setting extended display

  - by rfc1484

  I have Ubuntu 11.10 and I'm trying to set up extended display for my two displays. I have an AMD 6870. fglrx and fglrx-updates are installed. When I launch amdcccle trough the terminal (using sudo), I select in tab "Multi-Display" the option "Multi-display Desktop with Display(s)". Then it says for changes to be done I have to reboot my computer. Being a good an obedient lad I do just that, but after rebooting the displays are still in the same "clone" option as before in the Catalyst Control Center and no changes are made. Any suggestions?

• Creating static NAT blocks outbound traffic Cisco ASA

  - by natediggs

  Hi Everyone, I have two web servers sitting behind a Cisco ASA 5505, which I don't have much experience with. I'm trying to create two static NATs. One static NAT that goes to xx.xx.xx.150 and another that goes to xx.xx.xx.151. I've created the static NAT for the .150 web server and it works FINE. Incoming and outgoing traffic work great. This is the staging web server. I now need to duplicate the setup for the production web server. So, I connect the webserver to the firewall, change the public IP address on one of the NICs reboot the server and I have outbound internet access. Then I run the command: static (inside,outside) xx.xx.xx.150 192.168.1.x which is successful. I then run the command: access-list acl-outside permit tcp any host xx.xx.xx.150 eq 80 Which is successful. I then try to browse the internet and I get nothing. I try to telnet in through port 80 and I get nothing (though I'm guessing because the response to the telnet request is being blocked). I've tried this with the production web server and then I tried it with another web server that is for internal testing and have the exact same problem. Both work fine until I run the static NAT rule and then no outbound internet access. I have a feeling that it's something simple that I'm missing, but my limited experience with this device is killing me. Below I've pasted the current configuration. I'm currently trying to get this to work on the .153 server which is the internal testing server. Once I can verify that works, I'll try it with production. : Saved : ASA Version 8.2(4) ! hostname QG domain-name XX.com enable password passwd names ! interface Ethernet0/0 switchport access vlan 2 !

  We are evaluating the Cisco SA 500 router for our new office router. Would anyone recommend another similarly-featured router from another manufacturer? Requirements: - Office of 14 people - We are likely to switch to 14 VOIP phones (Linksys SPA-942) soon - We want to use VPN on the router, if possible, with Windows and Mac users
