Ports are remained blocked

Hi all,
I have a service with weblogic application server 8.1.2, running on Solaris 9 machine. Though the service is stopped,and it shows the status as it is not running, but the port which was using by this service earlier is still open. Is this problem something related to incompatibility between (Solaris + JVM + Tomcat).
Thanks in advance for your response,
Rajendranath.

Ports are being block (not responding)

Ports are being block (not responding), port forwarding is configured on the router and firewall is turned off on the server (osx 10.8). Am I missing anything?

I'm setting up VPN server and need ports 500, 1701, 1723, 4500 open
Thanks

Depending on the exact set-up of the network, L2TP requires UDP ports 500, 1701 and 4500 and the IP-ESP protocol, which is IP protocol 50; ESP.
Other than ESP (which is protocol 50 and not port 50), these are UDP ports, and not TCP.
TCP 1723 is used for PPTP. Not L2TP.
It is common for L2TP passthrough to fail when more than one connection is active.
As compared with L2TP, PPTP is usually easier to get going around NAT. Though conversely, L2TP is rather more secure than PPTP.
Check your Mac OS X Server firewall settings, too. If you have some outboard network device providing a NAT gateway, try dropping the server firewall.
Use of an external firewall-gateway with an embedded VPN server is something I've variously recommended, too. (I find that VPN NAT passthrough is something best avoided, as VPNs and NAT are operating at crossed purposes. VPNs seek to keep connection end-points known, while NAT tries to hide those connection end-points. Doing the VPN processing on the Internet side of the NAT is just... well, easier.)
Also ensure that your ISP is not blocking VPN connections. While you might be on static IP, confirm the ports are open. Trust, but verify. Get yourself a UDP port scanner, and have a look.
If it's permissible within your ISP service tier (and depending on what protocols you're testing), probe the specific target ports using telnet or the openssl s_client command and (particularly for this case) the nc (netcat) tools, and see if the ports allow access. nc can run port probes on UDP, which is the key piece here given telnet and s_client target TCP and TCP SSL connections. Probably something like the nc -zu w.x.y.z udp-port command.

What incoming public TCP ports are blocked?

I just setup my 890L to forward incoming public TCP ports to to a couple of my LAN devices. Unfortunately, it looks like VZB is purposefully blocking common incoming TCP ports.
I tried searching on google.com for what ports are blocked; but, just found a bunch of posts like this one. Some people actually tried contacting 1st and 2nd tied VZB tech support about this; but, it's clear they don't have this information available to them.
Has anyone verified what incoming public TCP ports are not blocked? There's no easy way for me to test this using my 890L.

You can find out for yourself which ports are being blocked by using a Port Query utility. Depending on the OS of your computer there should be multiple utilties available for free floating around.
As we have seen numerous times before, devices on VZW's new SIM card/4G LTE network are blocked from many of the public facing services and features we have previously been dependant on. Public IP Addresses, Public Ports, Webcams, VOIP phones, etc. all suffer under the same umbrella of limitations on the new network. The list is too long to publish everything that is blocked or not working as it previously did. Much easier for you to post the requirements of your application and have us confirm if its working or not.
If you have not already experimented with VPN's I'd suggest checking them out. VPN's are one of the easiest ways around these new limitations. With a VPN enabled your device will tunnel all of its communications out an allowed port to a VPN server where your traffic is free to act normally before returning to you.

What Ports Are Blocked using my Wireless Card

Can someone tell what ports are beeing Blocked by Verizonwireless when using my Wireless Card? Also, how do I get one open for example port 4444?

i don't think that the url blocking should block any ports ... however , if its doing this .. you may need to upgrade / reflash the router's firmware .. after the upgrade , reset and reconfigure the router ..

What ports are blocked with Homefusion

I am trying to figure out what ports are blocked on the homefusion service.

There is no official list of blocked ports for HomeFusion or any of the other VZW products. All products are treated the same way. The NAT firewall on VZWs new LTE network is responsible for blocking internet communication as well as hiding public IP Addresses. No manual configuration of the devices themselves will allow you to work around the issue. In truth it would be easier to create a list of the allowed ports but we don't have one of those either.
A rule of thumb is that you should assume any custom or unusual ports are blocked. Even the less popular mainstream ports are blocked some times. Only the major mainstream public ports are normally available. You have to test out your applications to know for sure if they work. If you have a laptop then stop by a VZW store and use one of their devices to test if it works before you buy.
Also, anything depending on Public IP Addresses is broken on the new LTE network. Some common examples are VOIP phones, Xbox hosting, IP security cameras, etc. If you need remote access to your local network then forget about it.
The work around to blocked ports and Public IPs are as follows:
1. Setup a VPN to connect to a network where the ports are open
2. Purchase a static IP Address from VZW for $500.00
3. Use a different ISP
VZW does not make exceptions for port blocking. You have to work around them or get by without them.

VGA and HDMI ports are next to each other; any VGA cable blocks HDMI port; want 3 displays.

The VGA & HDMI ports are right next to each other on the left side of the laptop. I ultimately would like to connect two monitors to it, but am unable to occupy both ports because the everyday end of a VGA cable/extender is too wide. Any solutions?

Hi, Firstly you won't get 3 displays without buying more hardware for your dv7 that why you won't be able to plug 2 ports at the same time. Regards.

What TCP ports are used by Push notifications

I believe my Firewall is blocking Push Notifications on my iPod touch. So, I wanted to discover what the TCP Ports are that are used by Push so I could open those ports to pass packets (info) to my iPod.

See:
http://support.apple.com/kb/HT3576
"If you are still unable to receive notifications and you are using a Wi-Fi connection, verify that the network or firewall is not blocking access to port 5223."

Some ports randomly get blocked and the external program is unable to rece

We have configured few ports to send out Idocs using TRFC mechanism. Initially all the ports are working fine and the external program is able to receive Idocs from all the ports. However after sometime, some ports randomly get blocked and the external program is unable to receive Idocs from these ports. If the SAP instance is restarted, we see that all ports work fine for a certain period but the same issue appears again after sometime.
This behaviour is observed in case of TRFC calls but not for normal RFC calls.
RFC Connections,partner profiles,ports,distribution model - these all are working fine.
Your help will be appreciated.
Thanks in Advance,

Port 5900 appears blocked from WAN

I have 39 Macs I am remotely administering but a few (2) seem to have port 5900 for VNC as blocked. We have rules out our router as a PC at the same location can VNC no problem through that route/firewall. So it seems to me that the port is being blocked on that Mac. The remote management setting are all set to allow and the internal ipfw is turned off. At one time IceFloor was installed but those settings have been dumped and uninstalled. Is there a way to restore all the ipfw setting to open to ensure it is not the Mac blocking the port?

Looks like I can't edit my original question...
The problem is still happening, I've been doing some testing to narrow it down...
+ it's not just my computer (have also tried from my mums PowerPC and my sisters iMac), although it could be a mac thing (I don't have a windows machine to test from, only windows running on a mac, though I will give that a shot later)
+ it's not my internet connection (although it could be my ISP - I tested at my sisters place, who uses the same ISP as me, am looking for another testing location that has a different ISP)
+ it's not my website (have tried uploading to a completely unrelated website with similar results)
+ it's not cyberduck (have tried with filezilla, similar results, also tried via terminal - I don't know how to upload files, but when I connected, it connected through a different port, a 5 digit number, can't remember what now).
Not too sure where to go from here...

How do I check to see if certain "ports are open?"

I need to open four ports and have no idea how. My web host thought that my ISP was blocking them; the ISP says they are not and that it is teh router. I don't have pjone support anymore (WRT54G is old) so could not be walked through it by a tech support person. If anyone can help me, I would appreciate it. Thanks in advance for your help.

there are port scanners online that check which ports are "open" between your LAN and WAN interfaces. just do a google search.

I read somewhere that all the ports of a switch will participate in STP by default. Is there any way to remove the STP operation on host ports ?
Regards,
Chandu

All ports participate in Spanning Tree by default.
Spanning tree is there to block redundant L2 paths in order to prevent loops. All ports are capable of causing a loop so you would not want to turn spanning tree off, in fact I don't think you can switch it off on a per port basis. You can switch it off on a per vlan basis.
You are already using portfast which allows host ports to transition into a forwarding state without going through the listening and learning states of STP. If you switch off STP on a port, you risk the chance of a L2 loop.

HT201320 how can i stop automatic configuration of email accounts on my ipad...the ports are not correct and i cannot access my email

i cannot get my "frontier" email account set up on my ipad so that i cannot either or receive email. Frontier says that the "automatic" verifying tool puts the wrong ports in and that is why i cannot get or send emails from the ipad. We know we have the correct name and password in but when in comes to verifying, an error message comes up and says "the wrong user name or password has been entered".
How do i disable the automatic set up of email so i can be assured the correct ports are enabled?

-Tap "Settings" app,
-Select "Mail, Contacts, Calendars" option on the left hand side,
-On the right, under "Accounts" on top, tap "Add Account...",
-Select one of the email service providers or "Other",
-Under "Mail", tap "Add Mail Account",
-A window pops up and enter your new email account details.
-Repeat for new email accounts.
