VNC cannot connect to port 5900

I have a VNC app on my iPhone and I enter the ip address but when I try to connectt it says it cannot connect to port 5900. Please help.

Have you opened the ports on the linksys router for VNC...?
Try this link and open the required ports on the router using port forwarding.Also,check this link to use VNC on your iphone.

  • Cannot connect to port 25 externally and owa is not working

    Hi all,
    just finished installing exchange 2013 and all went well.   Internally, everything works perfectly.   However, I then moved my testing externally.   Browsing to https://mydomain/owa times out - as does https://mydomain/ecp   
    Also, I cannot telnet to my mail server either:  telnet mydomain 25 times out.  I can though telnet mydomain 143 and telnet mydomain 110 no problem.
    I have setup the receive connector as per the instructions (in fact, it was already setup) the frontend default allows anonymous access (as it should).  Windows firewall is off.  Router forwarding ports fine.
    I can telnet 25 locally and as I said, everything works internally.    Clearly, there is another step that has to be taken to allow external access to the port 25 and also for owa and ecp.  I have double checked the SERVERS - VIRTUAL
    DIRECTORIES area and all the external url are correct.  Can someone help please?

    Ok, I rechecked my router page by page and have found one solution .. .the https management page of the router defaults to 443 - so have changed that to 4443, rebooted router and can now access my http://mydomain/owa - so that is good.  However, still
    cannot telnet to port 25 on the exchange server from external.  The port forwarding is definitely correct for port 25.
    I have rechecked the receive connector:  MAIL FLOW -  RECEIVE CONNECTORS - DEFAULT FRONTEND SERVER
    and under security - anoymous users is checked.   That SHOULD let me connect yes?  But it does not.
    Where else does this need to be changed - can you advise?
    regards

  • Cannot Connect to Port 26 - Cannot Send/Receive Mail

    I have Maverick on my MacBook Pro.
    All of a sudden, with NO CHANGES MADE to my system, my email no longer works. I cannot send or receive. I get the error:
    ===========
    The server “mail.mydomainnamel.com” cannot be contacted on the default ports.
    Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent.

    =============
    I use port 26 to send. Receiveing is mail.mydomain.com
    OSX recently updated. Could that of screwed up my settings or broke something?
    My internet proider says the issue is not on their end.

  • Server error, cannot connect to port 110

    Hello Support,
    I'm trying to set up a mail account but can't connect to port 110. The mail account works on my old powerbook. I've tried changing the settings to 111, 125 etc. No luck.
    What am I doing wrong???
    Please help...

    I'd call your ISP and go through your settings with them. It's likely that something in your setup is incorrect, or they changed their server to require new settings recently.

  • Printer cannot connect at port 9600

    Hello,
    OS 10.5.6
    I have a Laser Jet directly connected to one computer with an ethernet cable. The IP address and default gateway are set at 192.168.1.15 and the subnet mask is at 255.255.255.0.
    When I try to print there is an error which says :
    "Attempting to connect to host NPIC86923.local. on port 9100
    Unable to connect to printer will try in 30 seconds."
    All the addresses seem right, the printer shows up and the driver is the newest from HP for OS 10.5
    Ideas?
    Thanks, Garrett

    The printer's assigned IP address cannot be the same as your network's default gateway address. Typically the router's gateway address might be 192.168.1.1. The router may serve addresses between 192.168.1.2 and 192.168.1.199. The printer's IP address must then be somewhere within that range.
    If the printer supports DHCP then it would be preferable to configure the printer to use DHCP rather than trying to assign the TCP/IP parameters manually.
    Open Network preferences on the computer and select the Ethernet port. The displayed information will provide the Router or Gateway IP address for your network.
    Select Mac Help from the Finder's Help menu and search for "add printer" to locate the help articles on adding and configuring a printer.

  • Cannot connect 4-port switch to hub3

    Hi, recently had infinity installed and we are absolutely impressed with it and speeds in excess of 75down which is fantastic!
    So the setup we have is the router downstairs, and an ethernet going from that to the 4-port switch which was all set up for us by the engineer.
    What I wanted to do however, was to plug another 4-port switch (a white 'PEAK' branded wifi switch) into one of the 4 ports of the hub3 in order to increase the capacity up to 7 ethernet sockets.
    This setup worked fine when we was with sky over on the old DSL line where the 4-port swtich simply went into skys netgear switch and worked automatic.
    However, since switching to bt infinity, for whatever reason, this white switch will not work with BT's hub3.  By plugging a computer into the white switch, i can access the actual routers setup page by typing in 192.168.1.254, and can access all the settings.  The following settings come up...
    INTERNET: Connection Method - DHCP
    Internet IP Address: 192.168.1.67
    LAN: IP Address 192.168.1.254
    LAN: Network Mask 255.255.255.0
    LAN DHCP Server: ON
    But like I say, the switch, which has got a cable coming from one of the HUB3's 4 ports into my old white PEAK routers INTERNET port, will not allow my old switch to access the internet.
    So im really confused.  Why will my old switch not work on the BT Infinity HUB3?

    Thanks for both your replies.  I read them earlier in the day, and been trying a few things out...
    1st, I tried plugging the hub3 into lan4 on the peak switch, and the other 2 (sky and roku), along with my laptop for testing purposes into 1, 2 and 3, and all worked great!
    Well... all wasnt so great, the connection was sporadic and intermittent, ping was low, and throughput was fast, but it was on and off.  A speedtest.net would stall, web links sometimes took 2 or 3 clicks, and so on.
    So what have I learnt?  Well, the fact that it has an internet port (which I was wrongly trying to use before), means that it isnt a basic switch.
    So today, I went and bought http://www.tp-link.dk/products/details/?model=TL-SF1005D.  Plugged that in the same way, and everything works perfect!
    So now, I have the router (downstairs), plugged into the hub3 (upstairs via existing ethernet run throuth the stairs), 3 ports plugged into 2 pc's and 1 youview box, the 4th into a powerline socket upstairs,, with the other powerline socket plugged in downstairs behind the TV, connecting to the tp-link switch socket 5, with the sky+HD and Roku XL plugged into 1 and 2 on the switch respectively, and after testing I now everything running lightening fast with HD on demand, and the world is good
    So thanks for both your advice, i learnt a bit today.

  • Apple Remote Desktop, VNC, and port 5900 LAN weirdness

    Hi all,
    I am trying to share screens with a Mac Mini running ARD in OS X 10.3.9 over a LAN from my Macbook Pro (10.4.11). I have an Airport Extreme base station (7.2.1). The Mini is connected to the base station via wired Ethernet cable, the Macbook is wireless.
    I'm using Chicken of the VNC (2.0b4) on the MacBook, but I can't get anything but Connection Refused.
    * The software firewall on the mini is off (I'm behind NAT)
    * I've turned on ARD in the Sharing prefs control panel, set up the users and checked all the "allow" checkboxes (and restarting the mini)
    * I've tried connecting to port 5900, 5901, and 3283
    * I've tried enabling port mapping on the Airport (which seems crazy, since this is all happening within the LAN)
    I can SSH to the mini just fine from the Macbook. Using NetUtility, I can ping it, traceroute to it, you name it.
    The only weird thing that I can find is that when I do a Port Scan on the Mini, it never returns port 5900 as open (which it seems like it should). Other ports return as open.
    I've Googled my brains out looking for answers on this, and the best info that I can find points toward a network config. problem. But if that's the case, why can I SSH okay?
    And yes...I could upgrade to Leopard on the MacBook. Or install OSXvnc on the Mini. But I can't see why I wouldn't have exactly the same problem. And, dadgum it, this should work!
    I'm totally stumped (and have a sneaking suspicion that I'm missing something obvious). If anyone can shed light on this, or point me at a resource, I'd be very grateful.
    thanks,
    c

    Thanks to the folks at macosxhints.com, I have discovered that ARD in OS X 10.3.x doesn't support VNC connections.

  • ARD/VNC connection logging? Port 5900 attempts not getting logged

    I have a 10.7.5 machine on my home network with the built-in screen sharing turned on. I connect to it from work with the standard Screen Sharing app, so it's a basic VNC connection using the default Apple client/server software on the default port 5900.
    These connections show up in /var/log/secure.log like this:
    Jan 15 10:16:41 MyServer screensharingd[7630]: Authentication: SUCCEEDED
    Jan 15 10:21:35 MyServer screensharingd[7630]: Authentication: FAILED
    But when I look at my traffic logs (using PRTG Network Monitor), I see frequent port 5900 connections to that machine that don't correspond with any secure.log entry.
    Where might those connection attempts be logged? Is there something other than screensharingd that might be handling port 5900 traffic?
    Thanks,
    Ian

    Got the answer on another tech board. It's just a port scan, not a connection attempt.

  • Windows VNC clients cannot connect to Snow Leopard Server native VNC server

    I am resurfacing the following related comment made in another post that discusses the same issue I am having with VNC on Snow Leopard. This is still an issue and I cannot connect to our Xserve's Snow Leopard Server with a VNC client on Windows.
    I don't want to install another third party VNC server onto our SL Server, and am looking for a VNC client for windows that will connect to our SL Server.
    Does anyone have any solutions?

    Re: Newbie: Connect Windows -> OSX Server
    Posted: Nov 4, 2009 9:26 AM in response to: Antonio Rocco
    I would politely disagree. Yes, definitely, the Mac 'Screen Sharing' app works a treat, and Apple Remote Desktop.app works as well, but I am coming from a Window's PeeCee.
    For me, connecting to my 10.5(.8) Server via tightvnc gives 'Server did not offer supported security type!". Using RealVNC to this machine states "No matching security types Do you wish to reconnect to ... ?" a telnet to this AppleVNCServer service (port 5900), shows RFB 003.889 *, or Remote Frame Buffer Major 3, minor 889.
    Also, connecting to multiple 10.6(.1) Clients with Tightvnc correctly asks for a password but then hangs at "Status: Security type requested". Using RealVNC opens, connects, asks for authentication, and exits. Telneting to this AppleVNCServer service (port 5900), also shows RFB 003.889 *.
    The Current Version of the protocol is supposed to be 3.8, that is Major version 3, minor version 8. Not 80 or 800 but Eight). http://www.realvnc.com/docs/rfbproto.pdf and I believe that tightvnc only supports up to version 3.7.
    On each station I have installed the 'old' OSXVnc.app as a service (to a unique port). OSXVnc utilizes protocol 3.3 and I can control them successfully, but that is of my own doing because of this issue.
    Now JollysFastVNC works a treat to any machine I have EVER tried to connect to. I have not tried COTVNC or any of the others (too slow for me, when they wer e around)
    Also, I just noticed that RealVNC states that their free and personal version will not connect to Mac OSX (x86 and PPC) but the Enterprise one will. I just Dl'ed the Enterprise Viewer and it gave essentially the same thing ('protocol is not valid' message, even after it asks for a password). Anyway, I am not here to hijack this thread, just trying to keep the info flowing and open.
    Maybe I am the only one with these problems but the bottom line is I cannot use Real or Tight, or UltraVNC to administer my server or clients as long as AppleVNCServer gives out the 003.889 protocol version.

    * The ProtocolVersion message consists of 12 bytes interpreted as a string of ASCII characters in the format "RFB xxx.yyy\n" where xxx and yyy are the major and
    minor version numbers, padded with zeros.

    Searching on the net brought me to the same solution that Mr. Hoffman found as well, I was a bit skeptical at first but since he recommended it, and all my other attempts failed, it was a last resort and I have some additional notes of my own for a successful solution. Read the two links below first before doing anything, as they contribute to the solution in tandem.

  • VNC, port 5900, help

    I want to set up a vnc connection to use my computer through my iphone.  When I run the program it tells me "VNC server not found on port 5900".

    If you have a firewall running on your computer you have to open port 5900 on that too. You also have to forward port 5900 on your router to the computer on your network (if you want to access it from the outside world).

  • HT1338 cannot connect my MacBook Air to a projector  -does not detect and 2nd monitor. I have a new Mini port to VGA cable made by apple. When I read online I see that many people have the same problem - Is this an Apple defect??????????????????

    I cannot connect my MacBook Air to a projector - It will not detect a 2nd monitor or display. I am using an Apple made Mini Display port to VGA adapter. As I read online I see that many other peple are having the same problem. Is this an Apple defect!!???? If so it just burst the bubble about how great macs are. I never had a problem with that on a PC. I hope I am wrong. What can you tell me?

    Hi There,
    I have had the exact same issue but with a projector.
    The issue lies with Mountian Lion 10.8.2.
    I tried many a combination with no luck to get HDMI working.
    Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
    Bought my macbook home and voila, now displaying through my projector.
    There is a small graphics update after 10.8.1 which seems to be the cause.
    Hope this helps.
    Thanks.

  • HT6437 My itunes cannot locate my ipod. All the sync option are grayed out and diagnostics says that itunes cannot find usb ports and that no device is connected when it is. What should I do to solve this issue?

    So itunes is giving me problems. Since around Christmas time, itunes decided to stop reading my ipod. I connect it to my computer with the usb cable and my computer will recognize that a device is connected but itunes will not. If I go to file->devices and try to sync, all of my sync options are grayed out, while before it would just automatically sync.
    When I run diagnostics it tells me that under ports that it cannot find usb ports (it has a green circle?), a type of cable isn't found, and that no device is connected with the usb cable (which my ipod is). I have been trying to fix this issue but nothing is working. I've tried restarting my ipod, itunes, and my computer, i've also tried resetting my ipod and uninstalling itunes then reinstalling itunes but nothing seems to be working.
    Does anyone know how to solve this issue?

    Do the USB ports work for other devices?
    Does the iPod charge?
    See
    iOS: Device not recognized in iTunes for Windows
    - I would start with                  
    Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
    However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Features app in the Window Control Panel. Then reinstall all the Apple software components
    - Then do the other actions of:
