Connecting to an NTP server

Good Afternoon.
I'm having a big problem connecting to an NTP server like www.worldTimeServer.com. I want to create a java application that can load time from such servers then display it in my time text field. I do not know how to start.
Can somebody teach me how to do it or give me a link that provides how-tos to do this.

There is a package provided by http://jakarta.apache.org/commons/net/
that have classes for ntp. I myself is new to this (very old) protocol but I'm
building an application that is needing this service so if
you find it helpful let me know.

Dreamweaver (on Windows 7) wont connect to IIS (v7) Server using "FTP over SSL/TLS..."

I am evauating wether to purchase Dreamweaver CS6...
Dreamweaver CS6 trial (on Windows 7) wont connect to IIS (v7) Server using "FTP over SSL/TLS (explicit encryption)". I have a NEW Godaddy SSL certificate installed on the IIS server.
On connecting Dreamweaver states: "Server Certificate has expired or contains invalid data"
I have tried:
-ALL the Dreamweaver Server setup options
-Using multiple certificates (tried 2048 bit and 4096 bit Godaddy SSL certificates)
-Made sure the certificate 'issued to' domain name matches my domain name.
I am able to connect no problem using Filezilla, with equivalent Filezilla setting "Require explicit FTP over TLS". I can also connect fine using Microsoft Expression web.

Thanks for your prompt reply.
My comments:
1) You should update your tread (forums.adobe.com/thread/889530) to reflect that it still occurs on CS6 (I had already read it but figured it was an old tread and thus should be fixed by now).
2) You said “These warnings will also pop up for your users if you have a store saying the SSL certificate does not match the domain/ip and this can make users checking out in a storefront very nervous” . This does not seem to be correct – my https pages display properly using the same Godaddy certificate … using IE:
3) Godaddy is not my host (I use Amazon AWS) – but the SSL certificate is from them.

Windows 2012. Assign RDS service Licensing Server on Standalone Server. Connect to the licensing server on the same server as RDS

I have installed Windows Server 2012 Standard. I wish to run this server as a standalone server using local users as the authentication for RDS and not part of a domain. I have my RDS licenses loaded in RDS licensing service and all license show up
in the Licensing Server. I get events telling me to connect to a licensing server and I find no configuration tool now to connect to the local licensing service. It will not let me connect to the licensing service on the same computer.

Hi Bill,
After referring to your post, we can understand that you are facing issue with licensing service for your RDS Server. As Ryan has provided great article for deploying RDSH server in workgroup mode you can refer that and also I would like you to check that have
you specify a license Server for RDSH server to use. You can perform this setting under
deployment properties of RD Licensing and specify the name of the server and in addition there is registry setting for this under below path.
Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Licensing
More information:
Specify a License Server for an RD Session Host Server to Use (For your reference)

When Firefox shows me an update and asks if I'd like to update, I click continue, but it doesn't update. It just goes to a "software update" window and says "connecting to the update server..." and then doesn't do anything else. It never updates. HELP!

When I sign on to Firefox, a "Software Update" pops up and asks if I'd like to update Firefox. I click Yes/Continue and when I do, the page says "Downloading Firefox" - connecting to the update server... - but it never finishes. It continually shows the blue/white striped line.

Start at '''http://www.mozilla.com''' and download the latest
version. At the completion of the download '''don't let the setup
start Firefox for you''', when the setup ends, start Firefox in your
normal manner this way you will be less likely to create a new profile.
The extra startup pages are temporary -- read them. The next time
Firefox comes up you should be back to starting with your normal home page.
Note: Firefox must be down once the install starts.
:Close Firefox with File>Exit. Then make sure Firefox is not running --
:On Windows: check the "Processes" tab in the Windows Task Manager.
:On Mac: Firefox > Quit then Command+option+Esc, if Firefox running use Force quit
'''Permission errors on Mac:'''
"If you were getting permission errors on a Mac, download the latest
Firefox version, then uninstall and reinstall Firefox. '''Do not let the uninstall remove remove anything but Firefox itself'''; otherwise, you will lose your profile directories and files as they contain your settings,
bookmarks, history, extensions, passwords, and cookies.
If you can't download as mentioned above, find your system and the Firefox version you want in releases, download and start the install as seen above

Help with connecting to NIST NTP server on port 123

I can get NIST time in Daytime format using the rt_nist_date_time.llb example posted on ni.com, but I cannot connect to NIST NTP format time data using port 123. I freely admit to being over my head with this stuff, and have spent much of this Thanksgiving holiday reading about UDP and TCP.
The attached vi summarizes what I've tried so far. The UDP case is what I thought would work, but I can't come up with a network address that the UDP-open vi likes. Can anyone out there help this n00b tell the time?
The attached file is supposed to be in 8.0 format, although I'm working in 9.0
Here is a link discussing the time formats: http://tf.nist.gov/service/its.htm

THANK YOU!!! I don't think I ever would have come up with connecting the web address to a Read or Write UDP rather than the Open UDP block. Not to mention starting by opening port zero.
Unlike TCP, UDP is a connectionless protocol. Here's a quick explanation in different words.
A udp packet travels from a [sourceIP, sourcePort] to a [DestinationIP, destinationPort].
UDP open basically reserves a local port used for sending (soucePort) and receiving (incoming packet with that same destinationPort). Since some local ports are always in use, you would generate an error if you would accidentally pick a used port. Picking zero is useful for requests (as in this case!), because the OS will pick an unused ephemeral port. The actual source port number does not matter because the NTP server will just send the reply packet back to whatever port it came from. (If you would write your own NTP server in LabVIEW, you would of course need to set the local port to 123, and would get a conflict if another NTP server is already running on your rig). Writing an NTP server in LabVIEW would be a trivial modification to the current code, try it! . Simply listen for packets on port 123, form a response packet based on the timestamp, and send it to whatever IP/Port it came from (that info is available from udp read) and then go back to listen for new requests.).
UDP write sends a packet to the server using the above opened local port as source port. You can use the same connectionID to write to several other servers and ports, because UDP is connectionless. (TCP is connection based, so a TCP connection involves a defined source/destination pair)
UDP read listens for incoming packets from all over the world at that same local port. It is very unlikely, but theoretically possible that other UDP packets will arrive at that same port, so you could even filter to make sure to read incoming packets until they match the port and IP of the original request. The current code is somewhat vulnerable to a DOS (denial of service) attack for example as follows: Imagine the guy in the next cubicle had means of sniffing your network traffic. He could write a small program that looks for your NTP requests and then immediately starts flooding your IP with meaningless UDP packets to the sourcePort you just used. The current program only reads one packet and thus will never see the return packet from the NTP server.
UDP close frees up the local port and the computer is now no longer listening for packets on that port. Of course you could keep the port open for the duration of the program, especially if you intend to send UDP request once in a while during execution.
Makes sense?

Why won't a Windows 7 client connect to my web server?

I've got 5 Mac clients that can connect to my Snow Leopard server. They use file sharing, iCal, and web services.
We're trying to put a Windows 7 client on the network to use just file sharing and web services. Unfortunately, I can't get the Windows client to connect to the server at all.
We're using an Airport Extreme as a local network router. All devices are successfully connecting to this device.
When I try to access web services on the server using the Windows 7 client, I get an error message that the server is inaccessible.
Anyone know what might be different about how the Windows device is accessing the server vs how the Mac devices are?

How are you trying to connect to it? Just typing in its web address in a browser?
Is your DNS configured correctly?

I suspected some issue with AV so uninstalled.
To resolve the Access Denied I followed these steps:
stop w32time
w32tm /unregister
reboot
regsvr32 /u w32time.dll
w32tm /register
sc query w32time -- you should see that the service is set to
shared mode -- this is presumably how it should be -- if you try to start right now, you'll get the expected 1290 SID-related error
reboot
w32time should now automatically start at boot up and be running -- that was my result -- it's running as shared, started on its own, and I can do the w32tm /query commands successfully
After rebooting the time service started.
I then repeated the steps:
net stop w32time
w32tm /config /syncfromflags:manual /manualpeerlist:"0.pool.ntp.org, 1.pool.ntp.org, 2.pool.ntp.org"
w32tm /config /reliable:yes
net start w32time
w32tm /query /configuration
And all worked. I'll wait a short while to see if this fixes the issue. I also have am SA case with MS so will confirm fix when resolved.

Connect Oracle 9 client from windows 2012 server to 9.0 oracle database

I have windows 2012 64 bit with installed oracle 9.0 32 bit client

Is it possible to make this connection because when i have tried to connect received this error ORA-06413 connection is not open

Trying to combine versions of the Oracle client that weren't even certified on Windows 2003 with a bleeding edge Windows 2012 system is a recipe for pain and suffering. Even if you appear to get things working, there are any number of bugs that will likely crop up over time due to the massive version incompatibility.
If i understood right i can't make connection between oracle 9.2.0 32 bit client installed on windows 2012 to connect to oracle server 10 i?As others have pointed out, you probably can though you'll need to change the firewall rules. As others have stated, the firewall changes you'll need to make should probably be the same for a 9.2 client and a 10.2 client. But if you're determined to work with highly unsupported combinations of software, you're likely to have to embrace the idea that you're going to be blazing some new trails and that you'll have to spend a decent amount of time debugging issues that arise from your very unique combination.

How To Increase TCP Connections in Windows 2012 Server

We have installed our Java application in Windows 2012 Server. After running for some time application started showing Connection Time out. We have set TCP Parameters MaxUserPort = 65534 and TcpTimedWaitDelay = 30.
We are facing the same issue, even after setting the parameters in windows registry. We have verified in our application, "There is no connection pool issue and no thread issue".
We are using JDK v6.0.29, Tomcat 7, MYSQL 5.5.
Apart from MaxUserPort and TcpTimedWaitDelay is there any other TCP parameters in Windows 2012 to improve performance of the server and our application.
2) At the same time we have found that ‘There is sluggishness in I/O process’. Is there any registry parameters to improve I/O performance in the system.
Thank You.

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.

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.

Error: Cannot connect to NTP server or NTP server is not running - Cisco IPS

This is different scenario here:
I have two Cisco IPS 4260-k9 and both are in production now.
One of the IPSs is configured with NTP and works fines, but another one is not.
When tried to configure when the device is ON and live in production and got the following error,
Error from CLI:
" Error: Cannot connect to NTP server or NTP server is not running "
Error from IME:
" Delivery failed.
err Unaccepable Value - cannot connect to the NTP server or NTP server is not running"
I am able to reach the NTP server, also the same NTP is working fine with other devices....
Am I doing anything wrong?
Please advise

Windows 2012 R2 RDWEB on a different port number

Hi All,
I am having a big problem at the moment.
When I launch apps on the Windows 2012 Remote Session Host server it keeps prompting for credentials.
I have 2 VMs under Hyperv-2012 R2:
VM1 is an Exchange 2010 server with OWA on port 443
VM2 is a Windows 2012 R2 Remote Desktop Session Host server which is also on port 443 for the gateway.
Both servers have a domain verified SAN certificate installed.
We only have 1 public IP address and HTTPS goes to the exchange server(OWA). There is a rule in the router for this.
To access the RDWEB I thought I create an inbound rule on the router to redirect traffic on port 1443 to port 443 an point to the internal IP address for the RDP server.
Therefore when from outside I type:
httsp://mail.domain.com:1443/rdweb, I get to the logon page after I supply my credentials, but when I launch the remote app I get the logon prompt repeatedly.
Then I changed the HTTPS in the router to my terminal server instead of the exchange server, and it works perfectly.
But I need port 443 for owa.
So I went in the RD gateway config and change the port in there from 443 to 1443 thinking this would do the trick, but it does not.
When I tried to access RDWEB from the outside it prompts again.
Are there any other ports I have to open for this to work on port 1443?
Maybe it has to do with the digital certificate not working with non standard ports?
Any help appreciated.
Thanks and regards
Ipnotech

Hi,
1. What is the name on the certificate assigned to the various RDS purposes listed in Server Manager -- RDS -- Overview -- Deployment -- Certificates tab?
2. Please run the following commands in an administrator powershell prompt:
Import-Module RemoteDesktop
Set-RDSessionCollectionConfiguration -CollectionName QuickSessionCollection -CustomRdpProperty "gatewayhostname:s:yourgateway.domain.com:1443"
In the above please substitute the public FQDN for your RDG server (mail.domain.com.au:1443).
3. In RD Gateway Manager, Properties of your server, Transport settings tab, please set both TCP and UDP ports to 1443.
4. On your firewall, please forward TCP port 1443 and UDP port 1443 to your RDG server.
5. Please double-click Set-RDPublishedName.ps1, agree to run it if you get the security prompt, and then enter the FQDN that matches what is on the certificate you are using.
6. After completing the above please refresh the RDWeb page if you have it open already, and then reply back with any error messages you may be receiving.
Please note that if you are using the same FQDN as your Exchange server you may need to reconfigure things a bit in order to make it work. For example, an outside user connects to the RDG using FQDN of mail.domain.com.au, then the RDG will attempt
to connect to mail.domain.com.au (internally), and of course it will be connecting to the Exchange server using the internal ip address. That is why I was suggesting a different name (and certificate) for your RDS server, like remote.domain.com.au.
It would be a single-name certificate which is inexpensive.
The DNS records both internal and external.
Thanks.
