Unable to open url

I want to open up a url http://dss123.svr.us.sotc.net:3380/abc/

However, i am getting a error while opening page in IE: cannot find server.

If i ping this site, i get response:

C:\Documents and Settings\xyz>ping dss123.svr.us.sotc.net:3380

Pinging dss123.svr.us.sotc.net:3380 [1xx.1xx.xx.2xx] with 32 bytes of data:

Reply from 1xx.1xx.xx.2xx: bytes=32 time=234ms TTL=57
Reply from 1xx.1xx.xx.2xx: bytes=32 time=213ms TTL=57
Reply from 1xx.1xx.xx.2xx: bytes=32 time=213ms TTL=57
Reply from 1xx.1xx.xx.2xx: bytes=32 time=213ms TTL=57

Ping statistics for 1xx.1xx.xx.2xx:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 213ms, Maximum = 234ms, Average = 218ms


However, a similar site that i open, opens successfully (This is a company private site)
http://dss123.svr.us.sotc.net:6180/abc/

What could be the reason for this, this site is not blocked by firewall.

From the addresses it appears that these are two sites on the same machine, dss123.svr.us.sotc.net, so you've proven you're able to reach the machine via ping and via port 6180 but it is not responding at port 3380.  This suggests that the server at 3380 is either blocked or non-responsive.  You indicate that the site is not blocked by firewall, but are there any non-firewall security rules that might be invoked somewhere in the path due to the port you're attempting to connect?  The IANA reserved service for port 3380 is SNS Channels rather than web services might there be a conflict somewhere in the network due to that?

If the site at port 3380 is non-responsive it may be due to misconfiguration, failed startup,  or unintended shutdown.

Is the site still accessible to others on your subnet?

>>ping dss123.svr.us.sotc.net:3380

That's not really helpful. In order to determine the availability of that address and port, much better to do
telnet dss123.svr.us.sotc.net 3380

Open in new window

sounds like their web server is down. Have you contacted the site admins?

If the server is down then how can i ping to dss123.svr.us.sotc.net and receive reply.
In the server, one port is responsive while the other is not.

This is the reply i got:
servers are not able to take that much load, bring down 6180 and start 3380 will come up.
I have already tried couple of time to bring up 3380, and I do not see any errors in logs, It died as it tried to come up.

can one port fail to start due to load, while other does load?

The machine dss123.svr.us.sotc.net is not down the service at port 3380 is down.

You said you were told that servers are not able to take that much load, bring down 6180 and start 3380 will come up and "I have already tried couple of time to bring up 3380, and I do not see any errors in logs, It died as it tried to come up."

If the server has been running for some time without problems, then something must have changed somewhere in the environment find that and your problem will be solved.  

Perhaps the app is storage constrained rather than CPU or RAM constrained.  Do you have plenty of storage available and privileges to access the storage?  

Perhaps the image was somehow corrupted, can you reinstall the image or recover from backup a copy of the last known good image?

 It doesn't really make sense that a long running service hsa recently died and is now unable to restart, but when you ask can one port fail to start due to load while other services load,  the answer is Yes if the resources needed by the service on the failing port are not available.

I didn't say the server was down. I said the *web* server was down

> In the server, one port is responsive while the other is not.

because the web server is down

> can one port fail to start due to load, while other does load?

Nothing to do with a web server. In point of fact, when i last looked the web server was up on that site. The services on the ports mentioned before were not

Whatever is using that port is down, whether its a web server or something different is not really relevant. Point is its not handling requests on that port.

It's to do with file permissions. Permissions on the file that is the application that runs on that port. If you don't know what that application is, then you can't determine the permissions on it.
