TCP DNS Connection Refused
I am testing an application which uses tcp for dns.
My ActionTec router is set to "Medium" so it should allow all outbound connections.
When I use a dns server on my network all is well. When I try to use the ActionTec for dns I get connection refused with tcp requests but udp requests go through. I suspect the dns server on the ActionTec does not support tcp but I would like confirmation in case there is a setting I can change to make it work.
$ host yahoo.com
yahoo.com has address 98.138.253.109
yahoo.com has address 98.139.183.24
yahoo.com has address 72.30.38.140
yahoo.com mail is handled by 1 mta5.am0.yahoodns.net.
yahoo.com mail is handled by 1 mta7.am0.yahoodns.net.
yahoo.com mail is handled by 1 mta6.am0.yahoodns.net.
$ host -T yahoo.com
;; Connection to 192.168.1.1#53(192.168.1.1) for yahoo.com failed: connection refused.
Thanks,

Keep in mind the ActionTecs are based around the dnsmasq lightweight DNS resolver if I remember correctly. If Verizon/ActionTec is using a version of dnsmasq older than v2.10, then it is a known limitation of dnsmasq to not support TCP queries. If someone can confirm what version the FiOS routers have, that would be great. This tool may be able to identify it:

If you'd like me to analyze it, please send me a private message with the URL to your result, unless you don't mind your IP address being given out to the forums.

Hi all I have a mac mini running OS X Server 10.6.8,
I have 5 users (iMacs) on a network, served by the Server. I have a BT Infinity ADSL connection connected to a Netgear FVS318N VPN firewall router then the Mac Mini Server, of late we have been having major DNS issues on the Server due to EDNS resluting in errors in the DNS logs such as:

I have a support call out to Netgear to find out of the issue is with them, does anyone out know how to resolve this issue from a Software point of view on OS X?
As a temporary solution I have added to the clients Google's DNS servers as 2nd and 3rd options which has resolved websites not loading.
Any help here would be greatly appreciated.
AnthonyWith OS X Server in a private address space, your DNS server should be your DNS server, and not Google's nor any other off-LAN DNS servers.
Here is some OS X Server DNS Server set-up information, and there's a link in one of the replies there to an EDNS testing tool. (This is generic set-up for DNS services, and not specific to EDNS. If your baseline DNS services on LAN are working and your server and all your clients are using your server for DNS translations, then ignore this.)
There are various EDNS sizing discussions around, including this one; these usually involve shutting down the server and modifying a configuration file, and that can (unfortunately) be somewhat hit-or-miss on OS X Server. (And these are not usually fruitful, either.)
The core question being what widget is nailing you; the gateway router is a good potential culprit, of course. -

Hi,
I've configured ogg between primary & DR server. I'm continuously getting the following error in my primary server for DP process & sometimes for EXTRACT process after which process goes in abended state.
WARNING OGG-01223 TCP/IP error 111 (Connection refused).
After starting the process manually, it comes in Running state. But this is frequent issue I'm facing for OGG configuration at my end.

Please guide me on this.
Regards,
Simon P- check your remote host server is up and running.
- check mgr process is up and running on target site.
- try this and see if network connection is OK..
telnet 10.10.250.198 7809
- try to copy a file (scp) from source to target (take a dummy file; size bigger than tcpbufsize)
- check ggserr.log file on target; you might see if there are any issues with server/collector port allocation/timeout.
hope this helps...
Thanks. -
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.

# sshd_config(5) for more information.

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.

Last edited by douglasr (2013-09-29 02:58:56)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:

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? -
TNS-12564: TNS:connection refused
Hi,
I have some PHP applications which connect to Oracle database.
I sometime receive the following error message.
Fatal NI connect error 12516, connecting to:

I already had that error message in the past. At that time, I looked at the V$RESOURCE_LIMIT view and I saw session and process parameters were too small so I increased its.
Now, I checked again to these parameters and values never went nearly the max values.

Is it possible it can from another thing ? What is the best way to never have this error message again ? What is max value for sessions and processes that Oracle can support ?
Thanks in advance,
Best regards.Why do I am having (HOST=178.32.113.43)(PORT=1521) in the error message? I am using only the DNS name.
my tnsnames.ora file:
NV =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dns_name)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = NV)
and in my php connection function I also use the DNS name as the host and username/password like:
$connect = ocilogon($username, $password, 'dns_name');
Should I connect in another way ? like:
$ora_host='(DESCRIPTION =(ADDRESS =(PROTOCOL = TCP)(HOST = dns_name)(PORT = 1521))(CONNECT_DATA =(SID = NV)))';
$connect = ocilogon($username, $password, $ora_host); -
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...

# The default is $myhostname + localhost.$mydomain. On a mail domain
# gateway, you should also include $mydomain.
# Do not specify the names of virtual domains - those domains are

# REJECTING MAIL FOR UNKNOWN LOCAL USERS
# The local_recipient_maps parameter specifies optional lookup tables
# with all names or addresses of users that are local with respect

# If this parameter is defined, then the SMTP server will reject
# mail for unknown local users. This parameter is defined by default.
# To turn off local recipient checking in the SMTP server, specify
# local_recipient_maps = (i.e. empty).
# The default setting assumes that you use the default Postfix local
# delivery agent for local delivery. You need to update the
# local_recipient_maps setting if:
# - You define $mydestination domain recipients in files other than
# /etc/passwd, /etc/aliases, or the $virtual_alias_maps files.
# For example, you define $mydestination domain recipients in
# the $virtual_mailbox_maps files.
# - You redefine the local delivery agent in master.cf.
# - You redefine the "local_transport" setting in main.cf.
# - You use the "luser_relay", "mailbox_transport", or "fallback_transport"
# feature of the Postfix local delivery agent (see local(8)).
# Details are described in the LOCAL_RECIPIENT_README file.
# Beware: if the Postfix SMTP server runs chrooted, you probably have
# to access the passwd file via the proxymap service, in order to
# overcome chroot restrictions. The alternative, having a copy of
# the system passwd file in the chroot jail is just not practical.

# TRUST AND RELAY CONTROL
# The mynetworks parameter specifies the list of "trusted" SMTP
# clients that have more privileges than "strangers".
# In particular, "trusted" SMTP clients are allowed to relay mail
# through Postfix. See the smtpd_recipient_restrictions parameter
# in postconf(5).
# You can specify the list of "trusted" network addresses by hand
# or you can let Postfix do it for you (which is the default).
# 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
# with the "ifconfig" command.
# 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"

# 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

# 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,

# A Postfix process will pause for $in_flow_delay seconds before
# accepting a new message, when the message arrival rate exceeds the

# See the discussion in the ADDRESS_REWRITING_README document.
# ALIAS DATABASE
# The alias_maps parameter specifies the list of alias databases used

# 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

#alias_maps = dbm:/etc/aliases
#alias_maps = hash:/etc/aliases
#alias_maps = hash:/etc/aliases, nis:mail.aliases

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. -
Unable to create a new tcp/ip connection in sm59
Hello Friends,
We are trying to connect genesys cti gplus adapter to SAP ERP.
While testing new tcp/ip RFC Connection in SM59 , the connection test failed.
Error Details:
Logon : Connection error
Error Details Error when opening an RFC connection.
Is it something to do with librfc32.dll file ? Do we need to register this file? There is one librfc32.dll in C:/win/system32. Do we need to replace this .dll with the current version of librfc32.dll.
I could find some errors in our gplus adapter trace file.
Can someone please help me in this. U can reply me on <email address deleted by moderator>
Thanks in Advance.

COUNTER 14789Hi,
It seems to me that your genesys cti gplus adpater is of the registration type.
And from the error file, it could not contact the SAP gateway to register.
It is so logical that the connection test from SM59 fails.
Check the hostname of your SAP gateway. Is it really in capital letters ?
Are you able to ping it from your adapter host ?
Is the system number of your SAP system 00 ?
You are not supposed to ask for information at your email address.

Remote Desktop 'Connection Refused'
Modem/Router Model: GT704-WG-B
Firmware Version: 30.17.0 (Red background)
Operating System: Windows 7 Enterprise
Here is what I have set up to allow me access from outside my network via RDP.
Router config: Security > Applications "RDP" Rule Applied | Port 3389 Start/End/Port Map Start
UPnP is on
Modem/Router Firewall is OFF
Windows Firewall is ON with TCP 3389 allowed In/Out
Local PC has static IP address outside of DHCP range
Remote desktop (any version of RDP) allowed in Computer > Properties > Remote
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...

Java.sql.SQLException: The TCP/IP connection to the host has failed.
Hello. I hope you had a happy new year! Now its back to work.
I am having a problem connecting to a remote SQL Server DB. I am using NetBeans 5.5 and the latest J2EE. I am able to see the tables in the IDE and bind objects to data. But when I run it it gets this:
java.sql.SQLException: Error in allocating a connection. Cause: Connection could not be allocated because: The TCP/IP connection to the host has failed. java.net.ConnectException: Connection refused: no further information
at com.sun.gjc.spi.DataSource.getConnection(DataSource.java:100)

I checked the SQL Server Configuration manager on that machine and TCP/IP connections are allowed. What else could be wrong?
Thank You."Connection refused" means that the client sends a packet saying "I would like to connect to port number NNNN please" to the server computer, and the server computer's OS sends the reply "there is no process listening to that port on the network interface you are using".
The database server is not running, or running but not listening to TCP/IP connections, or at a different port from what you think, or listening to only selected network interfaces (it is possible for a process to listen to a specific interface or a wildcard for all interfaces). A less likely scenario is that a firewall is sending the "connection refused" message.
First aid check list for "connection refused":
- Check host name in connect string.
- Check port number in connect string.
- Try numeric IP address of server host in connect string, in case name server is hosed.
- Are there any firewalls between client and server blocking the port.
- Check that the db server is running.
- Check that the db server is listening to the port. On the server, try: "telnet localhost the-port-number". Or "netstat -an", there should be a listening entry for the port. You need to configure the database to accept TCP connections; the server documentation or google should explain how.
- Try "telnet server-host-name the-port-number" from the client, to see if firewalls are blocking it.
- If "telnet" fails: try telnet with the numeric ip address.
- If "telnet" fails: does it fail immediately or after an obvious timeout? How long is the timeout?
- Does the server respond to "ping serverhost" or "telnet serverhost" or "ssh serverhost"? -
Connection Refused Error while running AS ABAP Initial Load
All,
I've never connected SAP NW IdM to an actual SAP system before, and I feel like I'm missing some obvious step of configuration, but I can't figure out what.
We are in the process of trying provision user accounts to our SAP ABAP systems. My first step was to try to read all of the existing accounts from the ABAP system:
Our Basis team created me a Communication user with the proper authorizations (I ensured that the authorizations included in SAP_BC_SEC_IDM_COMMUNICATION)
I created a repository using the SAP NewWeaver AS ABAP (Specific Application Server) Repository Template (No CUA, No SNC) using that user's credentials
I then used the Job Wizard and used the job template AS ABAP - Initial Load, specifying my repository above.
When I run the job I get the following:
Initializing SAP connection with parameters:
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server failed Connect_PM MSHOST=<IPADDRESS>, R3NAME=<SID>, GROUP=PUBLIC LOCATION CPIC (TCP/IP) on local host ERROR partner not reached (host <IPADDRESS>, service sapms<SID>) TIME Wed Jun 01 13:54:36 201 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -10 MODULE nixxi_r.cpp LINE 8840 DETAIL NiPConnect2 SYSTEM CALL SiPeekPendConn ERRNO 10061 ERRNO TEXT WSAECONNREFUSED: Connection refused COUNTER 1
Error Init failed
I'm running SAP NW IdM 7.1 SP5 on Windows Server 2003 with MSSQL 2005. The ABAP server is on a UNIX box with an Oracle 10.2 dB.
Is there additional configuration that needs to take place on the ABAP side to accept the connection?
I've tried to find documentation on this, but have been unsuccessful. If someone could point me to the correct documents, or at least point me in the right direction for troubleshooting, it would be greatly appreciated.Ankur,
Looks like the endpoint URL of the webservice is not updated and still pointing to the localhost. Try changing it to http://<ip_addres_of_your_server>:7101..... and see if it works fine then.

Connection refused to host: connection timed out
I have been struggling with this problem a couple of days now so I really hope someone can help me. I am trying to get rmi to work in a NAT environment. We use a firewall, so I have opened port 1099 and 2020 which I use as a fixed port for communication (just to be sure it is not a firewall thing); I use the following code:

Java.rmi.ConnectException: Connection refuse
Hi all,
I have built a simple RMI client server application.I can run client & server fine locally.
However if I test this appplication over the internet, I get this exception on the client:
java.rmi.ConnectException: Connection refused to host: 169.254.157.53; nested exception is:
java.net.ConnectException: Connection timed out: connectConnection refused to host:169.254.157.53
The RMI server is running on my PC and the client on a friend's remote PC.Both PCs are connected to Internet.
I don't have any firewall running on my PC (including windows XP firewall). The server RMI lookup on the client happens correctly,
the exception is raised when the client tries to call the remote method on the server.
Here is an extract of my RMI server code (it works locally):
public static void main(String[] args) throws Exception {
try {
// args[0] contains the database server name given as command line argument, arg[1] contains binary path that contains weather jpeg files
CPrimaryWeatherServer test = new CPrimaryWeatherServer(args[0], args[1]);
Naming.rebind("rmi://localhost:1099/WeatherPrimaryService", test);
System.out.println("Serveur m�t�o principal d�marr�");
} catch (Exception e){ System.out.println(e.getMessage());}
Here is an extract of my RMI client code (it works locally):
try{
rec=1;
leftClik=1;
System.out.println("Before RMI lookup");
IPrimaryWeatherServerService serveur =(IPrimaryWeatherServerService)Naming.lookup("rmi://"+primWS+":1099/WeatherPrimaryService");
System.out.println("After RMI lookup");
System.out.println("Before server method call");
z=serveur.getFullWeatherData(); --> exception is raised here
System.out.println("After RMI server method call");
I am directly connected to Internet using an ethernet card connected to an ADSL modem.169.254.157.53 is the automatic IP of my network card different from the IP given by my ISP. By the way, the client tries to contact me using my DNS name that resolves correctly to my ISP IP adress.
Thanks a lot for help,because I am guessing that a local IP address is being embedded into the stub so the clien't can't find the remote server. I am guessing because you didn't provide the exception or its text. Anyway the suggestion will cause the correct public IP address/hostname to be embedded into the stub.
