Cisco Firewall :: SSH Stopped Working On ASA5520?
Mar 27, 2012
I can no longer SSH to a primary active firewall. It had all of a sudden stopped working. However I am able to SSH to the secondary standby firewall without any problems. I did try to regenerate the RSA key on the primary fw, but still unable to connect. The only way I can connect to it is by using telnet.
I ran the "show asp table socket" command and I'm seeing port 22 listening on the primary IP address (not the standby), foreign address is 0.0.0.0:*. I did a packet capture on port 22 on the inside inside, seeing my request hit the fw and then right away a reset back from the fw.
version 8.2.(5)
model ASA5520
I'm hitting a bug in the software version I'm running? Or what else can I check before rebooting the primary fw?

I'm trying to configure an ASA 5520 with cut-through proxy feature. The user is required to be authenticated when trying to access an outside resource from the inside. This is a test lab before it is implemented in production. [code]

We care currently using an ASA5505 as our firewall and redirecting web traffic to a S160 Iron port. Recently the web filter stopped working and the only way to get filtering again is to reset the redirection.
1. Is there any available log information to find out about the WCCP process and maybe way it stops?
2. Are there keep alive packets or anything of that natural between the ASA and Ironport?

I've recently migrated a PIX 525 to ASA 5520, but for some reason (through ASA) the users from OUTSIDE aren't able access services published in DMZ as well as some DMZ servers aren't able to communicate to some OUTSIDE services.
-INSIDE to DMZ is working fine. (through ASA)
-INSIDE to OUTSIDE is working fine. (through ASA)
Below is the configuration from my PIX (where everything works just fine) as well as the one on the ASA (where there is a problem), what could be the cause?In the below case the DMZ hosts from 11.1.10.0 aren't able to access SMTP services (through ASA) and the OUTSIDE users aren't able to access DMZ web server (11.1.10.40) through ASA, this all just works fine with PIX.

I have a Cisco ASA5520 that I have setup to allow a GRE tunnel through from a router at site B. This all works fine when I use the below NAT with associated router object on the inside
object network SWTEST nat (inside,outside) static interface
My problem comes in that this kills off my Cleintless VPN connection to the same firewall, I changed my NAT to point at another of my statically assigned IP addresses, and then nothing works. Can anyone help with what I've done wrong, or what i should do? My rule base allows any GRE in from the source, and rules all look fine.

After I have upgraded our ASA 5510 to 8.4.2 I have problem with the management interface.Our former firmware 8.2.3 had no problem using the management interface as a DMZ zone, but after we upgraded to 8.4.2 we can't make it work.The interface and the protocol is up, when I type: show interface.But when I ping the interface from a computer connectet to the interface, nothing happens.
Even the logging shows nothing.

Our firewall expert has gone off on long term illness leave and I am trying to pick up the pieces :-(
We have an ASA 5520 (local office) talking to another ASA (remote office) via a VPN Tunnel.
My 1st problem is that I cannot ping from my inside network (local) to the outside interface of my remote ASA.
My 2nd is that I have debug enabled on my rules but am not logging anything.

I'm trying to setup the SSL VPN portal:When I connect via HTTPS to the ASA5520 outside interface I get the login prompt and after successfully login it takes me directly to the Anyconnect client download (starts Anyconnect immediately) even though in the group policy is configured to not prompt the use to chose the post login and the post login is ste to go to Clientless SSL VPN Portal?

we noticed that the Cisco Secure Desktop / Hostscan is not working with Internet Explorer 10 on Windows7/Windows8.
As described here, the SSL VPN is/should working but no documentation about Cisco Secure Desktop / Hostscan. url...It's a Cisco ASA5520 with the lates release.
- ASA Version 9.1(2)
- ASDM 7.1(3)
- Cisco Secure Desktop csd_3.6.6249-k9.pkg
- Hostscan hostscan_3.1.03104-k9.pkg

I've had 1 to 1 NAT setup for years now with no issues and the other day it simply stopped working. Rebooted everything, had ISP clear arp on their cable modem yet nothing going. As soon as I remove the 1 to 1 NAT on the router the PC has internet access. Add the 1 to 1 back and no out going internet. The configuration is pretty basic and has not changed.Thinking it could be a hardware issue I swapped it out with another RV042 I have with the exact config, same thing 1 to 1 NATs have no internet access. Upgraded one of the RV042 firmware to Firmware Version: 1.3.13.02-tm, had cable modem replaced, spent numerous calls with ISP. nada
I have found one interesting thing however, any internal machine which is set to dhp works fine, and static ip that does not have a 1 to 1 nat works fine and the last ip in the 1 to 1 nat range works fine. If I extend the range it is always only the last ip that works. Even if I add 1 to 1 nats one line at a time, it is always the last entry that works..

I was installing a IIS server to our client and created access - rules for http server and port translations. After that i noticed i lost local lan access trough vpn. Anyconnect and ipsec vpn. No other changes made to asa than those access-rules and nat changes. I'm trying to find out what is wrong, vpn connects okay, i can ping ASA but nothing else on inside network (for example dns server). Dns is not either working. When i ping local server, i can see in log.

I have tried a lot of drivers and even tried installing Vista 64 bit drivers (something that worked for someone in some thread), but it won't work.The adapter is recognized by the computer, but the smart wizard won't launch.

My router has been working for close to 4 years now with minor problems, just stopped yesterday, All my PCs lost wifi access and then when I looked at my Linksys WRT300N only the 4 Ethernet port lights were on. Unplugged plugged it again, I connected one of the PCs to the one of the Ethernet port, the PC is reporting that there is nothing connected to the other side. It's been 4 years already, I do have a Linksys wireless G router even older than this which is till working. I guess its spoiled, I don't mind replacing it

I have been using a d-link router for some time now and since yesterday it has stopped working ( I have an orange 'world' light on all the time) After looking around this site I have tried resetting etc and nothing works. If I plug the ethernet cable into the modem I can get on the internet if I plug the cable into the router then nothing. These are the details I got from the config all when I plugged the ethernet into the router.

Randomly my router stopped working in the middle of the night. I didn't think the issue was with the router so i called the Tech Support people from Brighthouse and they told me to connect directly to the modem so i did that and I had internet. But why would my router randomly stop working, I've had this Linksys Dual N bound router for a year and never had a problem with it. I want to think that its the internet providers fault but I guess I really don't know.

I have a toshiba satellite laptop (windows 7) with wireless on-board and an ethernet cable port. Up until last night, both worked flawlessly since I bought the computer a few years ago.
Now, the wireless still works in three different locations I have tried (i.e. three different networks), but the ethernet cable will not work. I thought it was the ethernet connection on the mobo at first, but then after acquiring a USB-NIC connection, I found I had the exact same problem... I can't connect to my router or even direct to the DSL modem using a ethernet cable. I know my system is good since all my other computers (7) work with wired connections, and my laptop doesn't work on other cables on which other computers do. Essentially, it appears that my computer has lost the ability to get an i.p. address using an ethernet cable of any kind. Both the onboard card and the usb-nic cable tell me they are 'working correctly' in the systems/devices/network adapters section. I have tried disabling one while trying the other. I have tried disabling the wireless while trying either, and still nothing.

I currently own a Sony Vaio Laptop that has been working fine for the last 2 years, I was happily on facebook when all of a sudden, my laptop started lagging massively and it disconnected me from wifi, I was shocked to find that when I tried reconnecting, the laptop decided to stop working for a second and my wifi stopped working completely, every time I disconnect the Ethernet cable from my laptop even though my wireless switch is on, it won't even pick up my Virgin Media superhub I have about 5 meters from my laptop, it indicates that there is NO wifi anywhere, just the ascending bars with a big red X on it

My desktop was wirelessly connected to a router. It was working perfect, I did a wired connection from the modem to the desktop and when I tried to get the wireless connection again it has not been possible. When I try network trouble shooting I get DNS server might be unavailable. Been reading around and tried many of the things that I've read but none has worked so far.

I have been a loyal customer of a hosting company for over 10 years. The main reason I have a dedicated server is to eliminate those shared-hosting issues.For the past 4 years the service has been getting crappier. In fact; this week alone the ftp stopped working, mysql stopped working, and email.It is now to the point I have to move all my domains, mssql databases, mysql databases, email servers and countless files.I have been contemplating to set up my own dedicated server (Mac) and hook it up to my ISP. Most of the websites I host are local - only one or two are national/international.

I recently reinstalled Vista on my Dell laptop.Before that,I could view and open shared files on my XP desktop, although the PC couldn't see the laptop.Now, I can get online, but can't see the PC in Network places.I've ensured both have same workgroup name.I think it may be due to Norton Internet Security,which I've renewed and reinstalled from new disk.But the former one didn't prevent file-sharing, albeit one way,XP to Vista.Before I uninstall Norton again, is there anything else I should have done after Vista reinstall ?

My Linksys router stopped working. Resetting it didn't restore it.I bought a new Linksys E4200 router and configured it to the same settings as my old router. However, now I can't access certain website like Hotmail, Facebook, a weather site and others.But I can connect to most other websites, stream video, etc. Any suggestions why I can't connect to Hotmail, Facebook, etc???? I have 4 computers (3 wired, 1 wireless) connected through the router and they all do the same thing.

My router suddenly stopped working yesterday and I've tried everything I can think of to fix it. I have one computer wired directly in to it and a few laptops that use wireless connections.The power LED and the internet LED light up, but the status LED and the WLAN LED do nothing. Pushing the factory reset button on the back doesn't seem to do anything.Can't connect to the router site (192.168.0.1) The internet works fine when I plug in to it directly, so its definitely the router.

I used the wireless adapter (Netgear - WG111v3) on my computer for weeks without any trouble at all. (At the time i installed it, I remember I found out it didn't work/didn't work well on windows 7 so I downloaded some driver or something -- Don't really remember -- and it worked fine.) Suddenly, today, it stopped working. I have tried a lot of drivers and even tried installing Vista 64 bit drivers but it won't work. The adapter is recognized by the computer, but the smart wizard won't launch.

My computer stopped being able to Remote Desktop to my server on my network. My backup software also doesn't recognize my server. But, I can access its folders using Windows Explorer. Any other PC on the network can remote desktop to the server and connect. What happened to my machine? This message appears when i try to connect: "Remote Desktop can't connect to the remote computer for one of the following reasons:
1) Remote access tot he server is not enabled
2) The remote computer is turned off
3)The remote computer is not available on the network
Make sure the remote computer is turned on and connected to the network, and that remote access is enabled."
My computer is:
AMD: Athlon 64 X2 5200+ 2991 MHz
Mobo: Gigabyte M57SLI-S4 v.2
RAM: 4GB Mushkin DDR2 PC2-6400
OS: Win 7 64bit
VC: Geforce GTX 470

"Ethernet Connection has stopped working".Its stopped working again and I've run the Network Test and the results are in the file REG.txt attached. I can connect to the internet via wireless OK but I had wireless turned off to run this test.I've proven the ethernet cable OK by connecting another pc to it which works OK.
