Cannot get SSH to forward through to my mac...

I finally ponied up the money and replaced my crappy Belkin G router with an Airport Extreme N router and I can't say enough good things about it. However, I am having a problem that I just can't seem to resolve. I have several services forwarded into my iMac such as FTP, BitTorrent, Blizzard Downloader, and SSH. All of them seem to work flawlessly except for SSH. If I try to SSH to my iMac from my macbook from within my LAN it works just fine (ssh [email protected]) so I know that SSH is running properly on my iMac and accepting connections. However, if I change how I SSH and try to access it through my router's external IP address I get a connection refused (ssh [email protected]). I know port forwarding is working on my Airport Extreme because if I FTP to that external address I access my iMac perfectly. I checked and the firewall is disabled on my iMac and the SSH forwarding on the Airport Extreme router is definitely forwarding all TCP connections on port 22 to port 22 on 10.0.1.2.
Anyone got any ideas? This is just baffling to me!!

OK, first, could you clarify this:
+Another thing I tried was plugging my MacBook into one of the Gigabit Ethernet ports on the AEBS and turning off the Airport card in my MacBook to ensure I was using Ethernet. I setup the Port Mapping on the AEBS to point that that IP address (which was 201) and still got Connection Refused.+
What I was basically doing there was making sure it wasn't just the Wireless part of the AEBS that was causing the problems. So I setup one of my macs on one of the Gigabit Ethernet ports on the AEBS. It didn't make any difference, I still couldn't connect to it.
And regarding the cable modem, there may be two options on how it handles the public WAN IP address (this option is available on my DSL modem).
Basically you can pass the public IP address to the AEBS (Ideal), or you can have your modem be assigned the public IP address, and then it assigns your AEBS it's own set of internal addresses. It is easy enough to tell, by looking at your AEBS in the utility. For IP address, if it is clearly a public IP address like 24.xxx.xxx.xxx or 69.xxx.xxx.xxx then you are good. If it is like 192.168.1.2 or similar, that could be the problem.
My cable modem just passes the public IP address right to the AEBS. If I look at the IP address that the AEBS has it is 74.166.xxx.xxx.
BTW, you might be able to config your cable modem by going to 192.168.0.1 or 192.168.1.1 in your browser, while directly connected to the cable modem.
I will go home and try to figure out a way to access the cable modem directly. Although I have my doubts since it is just passing the public IP address right to the AEBS. Not even sure what IP it would be using or if it is even running any kind of web services.

  • Cannot get adat channels 5 through 8 to produce signal in logic

    Recently bought an audient as880 going in to a universal audio apollo twin, I receive and hear signal on the console adat 1 through to 8 yet even with armed tracks correct input selected I cannot get adat channels 5 through 8 to produce signal in logic

    I am recording at 44.1, I receive signal but only through channels 3 and 4 and no others regardless which channel is selected.
    The word clock is on the Ua as this is the master the 880 can only be a slave.
    Thanks for coming back I appreciate the feedback
    Well, I don't know if this is your problem but you should have a single lightpipe cable coming out of the 880 into the Apollo, correct?
    The 880 should be set to Internal clock 44.1 the Apollo should sync to clock that's coming in on the lightpipe cable.
    What I described is the standard correct method for connecting two digital units in the configuration you're using.
    The Apollo can sync to external clock can't it. Also, if the Apollo has digital settings make sure they're on "8-ch ADAT" not s/pdif. (which is stereo two channel input)
    The problems you're describing could be caused by not having the clocks set correctly.

  • I cannot get Flash Player to install on my Mac

    I cannot get Flash Player to install on my Mac Air.  I have repeatedly confirmed that I meet the system requirements and installed and uninstalled the software.  It always fails at 51% installation and give me and alert that says Install Error.  Please help!
    MAC OS 10.8.5
    Safari 6.1
    Firefox 26.0
    Just performed the update to FP12 on my iMac.  Worked perfectly.
    MAC OS 10.6.8
    Safari 5.1.10
    Firefox 26.0
    It appears the problem is with the newer OS...

    "Allllllllrighty then!" as "Ace Ventura" said....
    The problem ISN'T with Flash Player...
    If you remember back in September, when Apple released the 10.8.5 update, shortly thereafter... you no doubt discovered a file named "mach_kernel" was in your Mac HD directory.  And... unaware of what it was, you deleted it.
    That (mach_kernel) is a base file of OS X and Apple screwed up the update and made it "visible" when it's supposed to be hidden.
    Hundreds of thousands of unsuspecting Mac Users worldwide deleted it and it'll make things worse as time goes by.
    YOU'RE in luck, though. I have a fix.
    If you have a TIme Machine and use the "Secrets" pereference pane to reveal "hidden files", you can restore it from a "pre 10.8.5" backup.
    If not, I have a "fresh" mach_kernel file you can download.
    You'll need to download and install the Secrets prefpane. It'll then be in your System Preferences.
    Make sure you have it set to "show hidden files"
    Check the box and you have to restart Finder
    Press "Quit This" and then go to the Finder Dock icon and right click it
    Select "Open"
    Open your TIme Machine
    Go back to September 28 or earlier.
    You'll see the mach_kernel file in the Mac HD directory
    (I can't show it in the TM because screenshots don't work while it's open but here it is in my MAc HD)
    Right click it and select "Restore to"
    Then, when it goes back to Finder, choose the Mac HD directory and click OK.
    It will place the mach_kernel back where it was and you can install software again
    DON'T FORGET to go back and hide your files (and restart Finder) again, or you'll have a mess with the clutter of hidden files everywhere.
    IF you don't have the Time Machine...
    WITH hidden files shown, download this file (mach_kernel.zip)
    Move it to your Mac HD directory and THEN unzip it with Stuffit Expander or TheUnarchiver, whichever you use (most people have Stuffit).
    You should see the mach_kernel file there.
    You can delete the zip file, and then go back to Secrets in your System Preferences, and uncheck Show Hidden Files.
    Restart Finder and it'll be safely hidden again.
    THEN you can install Flash Player and other software without the "General Installation Error".

  • Cannot get SSH thru DynDNS to work with Leopard

    Hi everyone,
    OK, I have been digging around online for a long time trying to find a clear answer to my problem, and I can't find it anywhere so I figured I would just start a new thread and see if I could get some help.
    I have an iMac connected wirelessly to an Airport Express which is plugged into my cable modem. I would like to be able to SSH into my iMac remotely. I have an account with DynDNS and have installed their daemon program, which detects my external IP fine. With Tiger, SSH and DynDNS worked great -- I regularly used SSH to sync up my school documents. However, with Leopard, I absolutely cannot get it to work. If I ping my DynDNS name or my IP address, it responds, but I cannot portscan my machine or access it in any way. Back To My Work works fine (when it works at all), but I want a solution that will always work with any machine.
    I am not a newbie and know a lot about OS X, but I am not very familiar with networking lingo and have been largely confused by the information I have found online about similar problems. If you have figured out a solution to this problem and can give me a clear explanation, I would love it. I seem to have read somewhere that this required me to set a static IP for my iMac from the Airport, but I haven't been able to figure out how to do that without breaking my internet connection.
    Thanks!
    Alex

    All my macs at home and in my office are running leopard. I have no problem with SSH logins from outside my network using a Dyndns name.
    From the mac that your using to engage the ssh connection use the host command in your terminal app to see if the dyndns name is resolving to the correct IP of your server.
    host dydns.name.org
    If that runs up the correct IP address engage the ssh connection using the IP address.
    If that works then your ssh client is having dns issues
    so engage the connection again with the dyndns name but use a very verbose login so see if it turns up an error
    ssh -vvv dyndns.org
    replace dyndns.org with your actual domain name.

  • Cannot get printer to work through Home Hub 3

    I have replced my old router with a BT Home hub3 and so far I cannot get the printer (HP Officejet Pro 8500A) to work.
    Printer appears in the "my network" area in the hub settings.
    It also shows up in the control panel.
    It is connected to the hub via an ethernet cable "to slot 2)
    Test pages from the control panel and the hub both fail as does notebook.
    The printer itself will print Configuration pages etc just fine.
    The old set up worked flawlessly and was easy to set up in minutes. What am I missing?
    Windows XP desktop.

    Is the printer still is still set to shared? Might of become unselected when you set it back up.

  • I cannot get on the internet through Ethernet

    Hi Everyone,
    I am 100% new to macs, I just purchased a mini used from someone and I have tried to set up the internet through ethernet card and it will not work. I have researched for two days now and there doesn't seem to be an answer. I have done it all using DHCP to try to automatically get the settings but it is bringing up 169 IP address is is wrong. I have tried manually entering the information in and no luck. It is connected straight from the modem there is no router. I am usually good with PC's and could fix everything but right now I am stumped. I am running Mac OS X v10.4 Tiger. I thought I would try this out to see if anyone could help.
    Thank you in advance

    OK, If they are not using fixed IP addresses, then you should be using THEIR Router. You should get your IP Address through DHCP from their Router. \[As an aside, there can be quite a large cascade of Routers -- yours plus theirs.]
    The 169.254.xxx.yyy address is the "self-assigned" address used by your Mac when no one responds to its initial broadcast of a request for assignment of an IP address. This is a complicated way of saying "no one will talk to you".
    One thing to check for before declaring their box dead is the lights when the cables are plugged in. No lights sometimes means you are using a cross cable where a straight cable is required or the reverse. Most modern Macs "sniff" the cable and adjust to use whatever cable is provided, but older Macs do not.
    Some providers grab the first M.A.C. Address (Hardware Address) they see, and limit connection to only that device, ever. So if your computer dies and you get a new one, you have to call them up and ask them to reset their box. Sometimes there is a procedure for a "Deep" reset in their manuals, and you may need to apply that now. \[and if you decide to add your own Router later, you call them and tell them you are installing a different "computer". Your Router then becomes the only registered device.]

    I cannot get adobe or quick time to download on my Mac Air.  Does anyone know how?  What do you use instead

    Welcome to Apple Support Communities
    Consider yourself lucky that your MacBook is still working. Now, turn it off. Wine may have damaged other parts of your computer.
    Then, take the MacBook to an Apple Store or reseller. It will be a very expensive repair, as it's not covered by warranty and the logic board has to be replaced. In some cases, it may be better to get a new MacBook.
    If you can't take it to an Apple Store, contact with Apple > http://support.apple.com/kb/HE57

  • HT4970 I have chosen not to use iCloud for the time being, and cannot get the Reminders i input on my Mac to replicate to my iphone and iPad?  any help is appreciated.

    I have chosen not to use iCloud for the time being since the syncing was inconsistently working with the calender and contacts;  and cannot get the Reminders on my Mac to sync/replicate onto my ios device, neither iphone nor ipad.  Help is appreciated in respect to Reminders.  Thank you.

    ok, thanks.  couple other questions...
    1. will it sync to my reminders on my MAC too if i enter via icloud?  if not, what's the reason for  having the reminder list available on my Mac if it can't sync? 
    2. I have 2 different email accounts, one with a .mac address and another with .msn.  both can be accessed via icloud.  i ran a test using my msn acct as the signin and it logged the reminder onto both the iphone and ipad fine.
    however, when i try with my mac address, it only shows up on my iphone, which list reminders under icloud(which worked on both devices and then under mac which worked only on the iphone, not ipad.  any idea why that might be happening?
    thanks for your help.

  • Cannot Get Music To Play Through CD Player!

    Hey guys, I am new to mac but have used iTunes for years. I know how to burn a cd off of itunes, even though I have never done so before, problem is I can't get it to play in my cd player! I have changed the format of the songs to mp3 but my cd player does not play mp3. My boyfriend has a mp3 player in his car and it worked, so I know itunes isn't totally screwing up. So what format do I need to have the songs in in order for it to play?? I have done it also through the default (AAC) and even WAV but when I put the cd in the player there is nothing there, just dead aire! PLEASE HELP

    I have changed the format of the songs to mp3 but my cd player does not play mp3.
    If your CD player will not play MP3 files, don't use MP3 files.
    So what format do I need to have the songs in in order for it to play??
    Select Audio CD for the format when you burn.

  • Cannot get WRT160N to Internet through Actiontec 1524 on Qwest DSL

    Suffice it to say, I have literally tried everything.  No wired or wireless computer connected through my WRT160N can see the internet.  I can use my old Linksys BEFW11S4 for all wireless and wired as long as the patch cable is connected from the uplink port on the linksys to my Actiontec 1524, and the BEFW11S4 is set up with static ip's.  The Actiontec then acts as the DHCP server for all the other computers.  The problem as I see it is that there is no uplink port on my new WRT160N.  I can't set it up for DHCP because it will never get an IP address from the Actiontec.  I can't set it up for PPPOe, even though it works from the Actiontec to Qwest servers and recieves an IP address, the Linksys never get an address.  I currently have the WRT160N set up with a static IP, within range and scope, with no duplicates on the network, but no computer, wired or wireless, can see the Actiontec much less the Internet.  There is no uplink port on the WRT160N, so I'm thinking that may be the problem in my case, I'm just hoping that someone has more brilliant ideas than I've run across so far.  Oh, and the WAN port..  is not an uplink port.  My BEFW11S4 has both an uplink and WAN port, so I know the WAN is different.  Someone mentioned that crossover cable might make a difference, but I've also read that the ports on the Linksys are normally autosensing.   Please give me hope that I didn't waste my money.  I've got a co-worker that has one but has cable for internet and had no problem what-so-ever.  I'm thinking the Actiontec doesn't like routers, but I'd need proof before I go beat up Qwest.
    Thanks in advance

    I should also mention, I brought the 160N into work, setup exactly like it was at home, dhcp, etc. and it all worked flawlessly.  Could it be the Actiontec has a penchant for not working well with routers??

  • Cannot get sound to come through my iPad it keeps coming up airplay dock connector and I can't switch it off ?, Cannot get sound to come through my iPad it keeps coming up airplay dock connector and I can't switch it off ?

    The sound on my iPad sound doesn't always work, it will work without headphones for less than 3 minutes when I'm playing music but will work for longer when I'm not. It will work for an hour maybe with head phones in but then stop, in which time I have to take them out and put them back in to get the sound to work again. When the sound isn't working airplay says the sound is coming out of a dock connector, and the option, 'iPad' goes.

    - Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so.
    Try the following to rule out a software problem
    - Reset the iPod. Nothing will be lost
    Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Reset all settings
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup
    - Restore to factory settings/new iPod.
    - Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack or other problem
