Connection Refused in HttpURLConnection

Hi all,
i am using the following code for connecting a remote system
try
URL url;
HttpURLConnection urlConn;
System.out.println("1.Connecting....");
url = new URL("http://125.103.83.155:8080/LMSoftware/DBUpdates.jsp?string1="+Processor+"&string2="+HardwareName+"&string3="+NICInt+"&string4="+NICExt+"&string5="+KernalV+"&string6="+KEY);
System.out.println("2.Connected to...http://125.103.83.155:8080");
// create HttpURLConnection
urlConn = (HttpURLConnection)url.openConnection();
urlConn.setRequestMethod("POST");
System.out.println("3.created HttpURLConnection");
// output contents
BufferedReader br = new BufferedReader(new InputStreamReader(
urlConn.getInputStream()));
while (true) {
String line = br.readLine();
if (line == null) break;
System.out.println(line);
System.out.println("4.Out put contents Reading Finished");
br.close();
// disconnect
urlConn.disconnect();
catch(Exception e)
System.out.println(e.getMessage()):
after executing the above code
1.Connectig
2.Connected to...http://125.103.83.155:8080
3..created HttpURLConnection
connection refused
is printing but my 4th statement is not executing but i am able to connect the above url through my browser
plzz can any one give me the suggestion
Tks in advance
S.G.R

At the point where you print 'Connected to ...' you aren't connected at all. All you've done so far is create a URL. It's only when you get the input stream that the connection is formed.
I would doublecheck the URL you are using in the code against the URL you claim works in the browser.

    What is this problem ?
    Can someone help us ?
    Thanks in advanced.

    but i am not send to the client when i accept the client connection immediately ,It doesn't matter when you send to the client. The answer is still the same. You send to a client via the socket you accepted from that client. That's what it's for.
    for example :
    first client_A connect to Server (port 2222) , than Client_B connect to Server (port 2222) , finally Client_C connect to Server (port 2222)You don't need to keep telling me the port number. If the ServerSocket is listening at port 2222 they will all connect via port 2222. They don't have any choice about that.
    and all not close the connection, but if I want to send some msg to Client_B from Server, how can i send the msg to client_B ?Via the socket you accepted from client B. I've already answered that.
    it's just like you said "you don't have to do anything about that. " ?Is that a question?
    You don't seem to have much idea about client-server socket programming. Have you read the Custom Networking tutorial?

    "Connection refused" generally means there is no server listening at the port you tried to connect to.

    thanks in advanced!!!

    Comment out your call to setDoInput(true). See if that helps. If not, then it is probably a configuration issue on the server you are attempting to send to.

    After working for a while I'm getting blocked. How can I go around it? Thank you very much

    It would appear that either a) you have the wrong IP address and/or port of b) the server is explicitly disallowing your connection.
    1) Find out the IP address and port.
    2) Put a logging statement in right before your call to the API's connect method that spells out what URL you're connecting to.
    3) Look again at the error message and see if it provides any more detail about the server/port than what you've provided here.
    If the above tell you that you've got the wrong address/port, then put the right one in. If they tell you that you've got the right one, then see if you can connect via telnet or web browser. If the other connection method also fails, then you need to talk to the owner of the site, or your company's firewall admins or somebody. If the other methods let you get through, then it's your code, and you'll have to post the code here to get help debugging it.

  • Connection refused is not raising an exception

    Hi, I am having problems getting my code to recognise that a url refuses a connection, eg "http://tigers.com.au".
    Opening the url in a browser correctly shows that a connection is refused.
    However, in Java (1.6_07) code as below, no exception is raised, and the response code is 200 OK.
    Even though no exception is raised, the content that is returned by the InputStream is actually from somewhere else (my local development server), so it seems that the connection is not actually successful.
    The code works fine for other urls that does accept a connection, eg it works fine for "http://www.tigers.com.au".
    Why is my code not raising an exception for cases where the url refuses a connection? Or is there a bug in Java?
    Grateful for any help.
              BufferedReader in = null;
              String s=null;
              HttpURLConnection urlCon = null;
              URL url = null;
              try {
                   url = new URL("http://tigers.com.au");
                   urlCon = (HttpURLConnection) url.openConnection(); 
                   urlCon.connect();
                   System.out.println("urlCon after connect: "+urlCon.getURL());
                         System.out.println("Response code: ["+urlCon.getResponseCode()+"] "+urlCon.getResponseMessage());
                   in = new BufferedReader( new InputStreamReader(urlCon.getInputStream()));
                   while ( (s=in.readLine()) != null) {
                        System.out.println("s: "+s);                    
              catch (Exception e) {
                   System.out.println("Exception: "+e);
              }

    Have found that wildcard addresses matches any address of the local system, and that in IPv4, the wildcard address is 0.0.0.0. Can check for this with InetAddress.isAnyLocalAddress().
    This means that I could potentially handle these cases by adding code to "ping" a host such as "tigers.com.au" using
    InetAddress address = InetAddress.getByName(name);
    if (InetAddress.isAnyLocalAddress() {
    .... do something, eg raise exception
    }But this is not fully satisfactory, as I would rather know that a "connection refused" exception is raised, which is actually the case with "tigers.com.au" (as all the browsers seem able to detect). I am not entirely sure what the relationship is between a site that has "connection refused" and it returning an ip address of 0.0.0.0. I don't think they are synonymous.
    Any thoughts?

  • Connection refused with HTTPS

    Hello,
    We have created a webservice deployed to WebLogic Server 9.2. It requires secure transport using the annotation
    @UserDataConstraint(transport=UserDataConstraint.Transport.CONFIDENTIAL)
    We're able to test this successfully using an XSmiles client browser.
    However, I've written a Java client started with "clientgen" that runs successfully when connecting in nonsecure mode (annotation removed) to a local instance. But when I try to connect to our remote server in secure mode I get "connection refused" (the lengthy call stack is copied below).
    The client code is also copied below (a few strings and IPs were changed). It's able to retrieve the WSDL, but then bombs when calling a port method. This is probably something simple but I've followed tutorials and have not found reference to this particular error on forums or via Google. Any ideas would be appreciated!
    Thanks,
    CJ

  • When I try to log in from desktop I get "Connection Refused" message. How do I fix this?

    I tried to activate Mozilla Firefox today using the normal & routine method, clicking on the Firefox Icon.
    Each time I tried I got the same message "Connection Refused".
    I went to the Firefox site and read the message regarding disabling Java, so I opened ADD ONS and Plug Ins and disabled Java.
    Still no change, so I shut down and restarted my computer.
    I keep getting the same Connection Refused message.
    What needs to be done to restore Firefox?

    Another user also reported a problem with the AT&T Yahoo home page in the past few minutes. When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
    (1) Bypass Firefox's Cache
    Use Ctrl+Shift+r to reload the page fresh from the server.
    Alternately, you also can clear Firefox's cache completely using:
    orange Firefox button (or Tools menu) > Options > Advanced
    On the Network mini-tab > Cached Web Content : "Clear Now"
    If you have a large hard drive, this might take a few minutes.
    (2) Remove the site's cookies (save any pending work first). While viewing a page on the site:
    * right-click and choose View Page Info > Security > "View Cookies"
    * Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
    Then try reloading the page. Does that help?

  • Problems with SSH: Connection Refused

    Greetings fellow Arch users,
    I have hit a bit of a snag that I could really use some extra help getting around. I've tried everything I can think of (and everything that Google thought might work) and I have my back rather against a wall, so I thought I'd come here to see if anyone can offer some advice.
    To make a long story short, I am a college student and am attempting to set up an ssh server on a desktop at my house so I can access it remotely from the college. I have the computer set up and the server running, however I am having difficulty making connections to it from my laptop. I know that the server is running, because I can log into it both from the server itself (sshing into local host) and from my laptop when I use the internal IP address.
    The server is on a static IP address within the network(192.168.0.75), and my router is configured to forward TCP port 1500 to it (I'm using 1500 as the port for my ssh server). However, when I attempt to log into the ssh server using my network's external IP address, the connection is refused. I used nmap to scan my network and found that, even though the proper ports are forwarded to the proper place as far as my Router's configuration interface is concerned, port 1500 is not listed as one of the open TCP ports. I also, to test it, temporarily disabled the firewalls on both the server and the client. That didn't help. The command that I am running is:
    ssh -p 1500 douglas@[external ip address
    As I am really not sure what is causing this problem, I don't know what information to provide. So here is everything that my inexperienced mind sees as likely being important. If you need anything more, let me know and I will do my best to provide it.
    Here is the sshd_config file from my server.
    # This is the sshd server system-wide configuration file. See
    # sshd_config(5) for more information.
    # This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

    Thank you guys ahead of time. Getting this server operational is hardly critical, it is just a side project of mine, but I would really like to see it working.

    Okay, so I finally have the opportunity to try and log in from a remote network. And. . .  it doesn't work. Which is just my luck because I now need to wait an entire week, at least, before I can touch the server again. Anyway, running ssh with the maximum verbosity I get this output:
    douglas ~ $ ssh -vvv -p 2000 address

    debug1: connect to address address port 2000: Connection timed out
    ssh: connect to host address port 2000: Connection timed out
    It takes a minute or two for the command to finish with the connection timeout, as one would expect. And yes, I am reasonably sure that the address that I am using is my home network's external IP. It is dynamic, but I checked it before I left which was just over an hour ago. I guess that it may have changed. I'll know that for sure in the morning, when my server sends me an automatic email with the network's current address. In the meantime I am operating under the assumption that the address I am using is correct. What else could be the problem?

  • Error while deploying module with iasdeploy : Exception while createXmlDocument() : connection refused

    Hi to you all,
    I work with iAS 6.0 sp2 on Solaris.
    For 1 day, I get that exception when trying to deploy or remove my modules (servlets + JSP) with the iasdeploy tool :
    Exception while createXmlDocument()
    java.net.ConnectException: Connection refused
    at java.net.PlainSocketImpl.socketConnect(Native method)
    at com.netscape.server.deployment.WebbAppReg.run(compiled code)
    at com.netscape.server.deployment.WebbAppReg.main(Unknown source)
    The war archive is put in the JAR directory, unpacked in the APPS/modules directory, but the servlets of the module have the null GUID in the registry ({000000 000000 000000}. And so, I have the GX error when trying to invoke them.
    What appends ? Is it a iAS process which is unable ?
    Please help !
    Paul-Emile

    I think you have not put the xml files in the war file.
    You need to put them under WEB-INF/ directory. Manually generate the guids using kguidgen script and try to deploy the war module. It should work fine. If it doesnot work please send me the file. So that I can further investigate and find out where exactly the problem is.Other wise you can use the deploytool.
    Please let me know if this works fine.
    Thanks for visiting our web forum.

  • Lion Server postfix mail not being delivered to mailboxes. "SMTP restriction `reject_invalid_helo_hostname' after `permit' is ignored" and "connect to private/policy: Connection refused" errors.

    All, Im stumped. In fact I have been on the phone with Apple Support and this has been escalated to the top engineers, as I think its got them too..
    Anyway, here is my problem..
    I'm running an Mac Mini with OS X 10.7.4 Server. I have had mail running on it for 2 months or so, without any issues. The mail was actually migrated from 10.6 in March, and It actually went smoothly. I have 3 domains which all recieve mail and they all work (or did up until 2 weeks ago)..
    So the story is this.. I can send mail from my domains, without issue.  imap and dovecot must be working.. cause all the stored mail, can be read with the mail IMAP client.. I can even transfer mail messages from one mailbox to another with Mail client. Sending mail is a breeze, it still works and the recipients still recieve their mail. But I noticed I wasnt getting any mail at all from those mailboxes... no mail, no spam, nothing.. which is unusal. I fired up Server admin and checked out the SMTP log, and this is what it showed for every email recieved: (xxxxxx is just me hiding sensitive info)

    Ok, now what is odd, is these rejected messages are not even appearing in the mail queue in Server Admin. I have no idea why there are not being delivered
    Ive checked my postfix main.cf file and master.cf files they both look ok.. Ive even replaced them with the main.cf.defualt.10.7 and master.cf.default.10.7 files and to no avail... same problem..
    So in summary
    I can send mail out
    IMAP is working on the client end (thus dovecot is) exsisting stored emails can be accessed, read, moved unread etc..
    mail is coming into the sever, but its being rejected. there is NO rejection email sent back to the sender.
    mail is recieved by postfix, but cyrus isnt doing anything with it.. I have no idea where it goes...
    Could anyone shed light on this...

    # By default (mynetworks_style = subnet), Postfix "trusts" SMTP
    # clients in the same IP subnetworks as the local machine.
    # On Linux, this does works correctly only with interfaces specified

    # Specify "mynetworks_style = class" when Postfix should "trust" SMTP
    # clients in the same IP class A/B/C networks as the local machine.
    # Don't do this with a dialup site - it would cause Postfix to "trust"

    #mynetworks_style = class

    # Alternatively, you can specify the mynetworks list by hand, in
    # which case Postfix ignores the mynetworks_style setting.
    # Specify an explicit list of network/netmask patterns, where the
    # mask specifies the number of bits in the network part of a host
    # address.
    # You can also specify the absolute pathname of a pattern file instead
    # of listing the patterns here. Specify type:table for table-based lookups
    # (the value on the table right-hand side is not used).

    # The relay_domains parameter restricts what destinations this system will
    # relay mail to.  See the smtpd_recipient_restrictions description in
    # postconf(5) for detailed information.
    # By default, Postfix relays mail
    # - from "trusted" clients (IP address matches $mynetworks) to any destination,
    # - from "untrusted" clients to destinations that match $relay_domains or
    #   subdomains thereof, except addresses with sender-specified routing.
    # The default relay_domains value is $mydestination.
    # In addition to the above, the Postfix SMTP server by default accepts mail
    # that Postfix is final destination for:
    # - destinations that match $inet_interfaces or $proxy_interfaces,
    # - destinations that match $mydestination
    # - destinations that match $virtual_alias_domains,
    # - destinations that match $virtual_mailbox_domains.
    # These destinations do not need to be listed in $relay_domains.
    # Specify a list of hosts or domains, /file/name patterns or type:name
    # lookup tables, separated by commas and/or whitespace.  Continue
    # long lines by starting the next line with whitespace. A file name
    # is replaced by its contents; a type:name table is matched when a
    # (parent) domain appears as lookup key.
    # NOTE: Postfix will not automatically forward mail for domains that
    # list this system as their primary or backup MX host. See the
    # permit_mx_backup restriction description in postconf(5).
    #relay_domains = $mydestination
    # INTERNET OR INTRANET
    # The relayhost parameter specifies the default host to send mail to
    # when no entry is matched in the optional transport(5) table. When
    # no relayhost is given, mail is routed directly to the destination.
    # On an intranet, specify the organizational domain name. If your
    # internal DNS uses no MX records, specify the name of the intranet
    # gateway host instead.
    # In the case of SMTP, specify a domain, host, host:port, [host]:port,
    # [address] or [address]:port; the form [host] turns off MX lookups.
    # If you're connected via UUCP, see also the default_transport parameter.
    #relayhost = $mydomain
    #relayhost = [gateway.my.domain]
    #relayhost = [mailserver.isp.tld]
    #relayhost = uucphost
    #relayhost = [an.ip.add.ress]
    # REJECTING UNKNOWN RELAY USERS
    # The relay_recipient_maps parameter specifies optional lookup tables
    # with all addresses in the domains that match $relay_domains.
    # If this parameter is defined, then the SMTP server will reject
    # mail for unknown relay users. This feature is off by default.
    # The right-hand side of the lookup tables is conveniently ignored.
    # In the left-hand side, specify an @domain.tld wild-card, or specify
    # a [email protected] address.
    #relay_recipient_maps = hash:/etc/postfix/relay_recipients
    # INPUT RATE CONTROL
    # The in_flow_delay configuration parameter implements mail input
    # flow control. This feature is turned on by default, although it
    # still needs further development (it's disabled on SCO UNIX due
    # to an SCO bug).
    # A Postfix process will pause for $in_flow_delay seconds before
    # accepting a new message, when the message arrival rate exceeds the
    # message delivery rate. With the default 100 SMTP server process
    # limit, this limits the mail inflow to 100 messages a second more
    # than the number of messages delivered per second.
    # Specify 0 to disable the feature. Valid delays are 0..10.
    #in_flow_delay = 1s
    # ADDRESS REWRITING
    # The ADDRESS_REWRITING_README document gives information about
    # address masquerading or other forms of address rewriting including
    # username->Firstname.Lastname mapping.
    # ADDRESS REDIRECTION (VIRTUAL DOMAIN)
    # The VIRTUAL_README document gives information about the many forms
    # of domain hosting that Postfix supports.
    # "USER HAS MOVED" BOUNCE MESSAGES
    # See the discussion in the ADDRESS_REWRITING_README document.
    # TRANSPORT MAP
    # See the discussion in the ADDRESS_REWRITING_README document.
    # ALIAS DATABASE
    # The alias_maps parameter specifies the list of alias databases used
    # by the local delivery agent. The default list is system dependent.
    # On systems with NIS, the default is to search the local alias
    # database, then the NIS alias database. See aliases(5) for syntax
    # details.
    # If you change the alias database, run "postalias /etc/aliases" (or
    # wherever your system stores the mail alias file), or simply run
    # "newaliases" to build the necessary DBM or DB file.
    # It will take a minute or so before changes become visible.  Use
    # "postfix reload" to eliminate the delay.
    #alias_maps = dbm:/etc/aliases
    #alias_maps = hash:/etc/aliases
    #alias_maps = hash:/etc/aliases, nis:mail.aliases
    #alias_maps = netinfo:/aliases
    # The alias_database parameter specifies the alias database(s) that
    # are built with "newaliases" or "sendmail -bi".  This is a separate
    # configuration parameter, because alias_maps (see above) may specify
    # tables that are not necessarily all under control by Postfix.
    #alias_database = dbm:/etc/aliases
    #alias_database = dbm:/etc/mail/aliases
    #alias_database = hash:/etc/aliases
    #alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases
    # ADDRESS EXTENSIONS (e.g., user+foo)
    # The recipient_delimiter parameter specifies the separator between
    # user names and address extensions (user+foo). See canonical(5),
    # local(8), relocated(5) and virtual(5

    Ok 1st one. The warning restriction message relates to this line in main.cf:
    smtpd_helo_restrictions = permit_sasl_authenticated  permit_mynetworks  check_helo_access hash:/etc/postfix/helo_access  reject_non_fqdn_hostname  reject_invalid_hostname  permit reject_invalid_helo_hostname
    The last reject occurs after the single word "permit" and is ignored.
    However, that's not the problem.
    I'm not exactly sure what's happening, but this might be a clue.
    It would appear that either postfix is not being able to create the socket for private/policy or it's somehow created with the wrong permissions.  You might need to ramp up the debug level to get a better idea.
    You could check if it's being created by "netstat -a | grep private/policy" in terminal.
    My guess is that it's not being created because there is no setup statement in your master.cf file, but I don't understand why postfix would be looking for it if it isn't set up.  Private/policy I think relates to grey listing.  Maybe gives you a hint.

  • Remote Desktop 'Connection Refused'

    I use Jaadu RDP iPhone application and have used it successfully for quite some time.  When I first got Verizon service I set up RDP on the router and everything worked fine.  I ran into an issue that caused a verizon tech to tell me to reset my modem/router to the factory defaults.  Ever since, I have not been able to access my local PC via RDP.  Every time I attempt to connect I get a connection refused message.  I receive the same type of message when attempting to RDP in from another PC.  I am able to RDP from within my LAN from both my iPhone and my other PC.
    I have crossed my Ts and dotted my Is and am at a loss at this point.  If anyone has experienced this issue and found a fix, I would appreciate some help.
    Thanks

    #1 If the router turn off UPnP, since you will not be needing it.
    #2 If that does not resolve it / or it happen again, please post...
