SYN timeout connecting to a server through the VPN
Hello,
I have a very odd problem. When connected to the VPN, I can connect to all my servers without problem on any services. On a single server, when I try to connect to Windows shares, it doesn't work. My event log shows nothing on the client or on the server but I get this from the ASA:
10-20-2008 20:54:45 Local4.Info 192.168.1.1 %ASA-6-302014: Teardown TCP connection 288013 for outside:192.168.2.1/1566 to inside:192.168.1.9/445 duration 0:00:30 bytes 0 SYN Timeout (user)
At home I'm on 192.168.50.xx, the lan at work is 192.168.1.xx and the VPN range is 192.168.2.xx.
Any ideas?
ER

I am trying to have access tables of the Sql Server through the Oracle
I am trying to have access tables of the Sql Server through the Oracle and this being occurred the error:

Please they help me, thanks, Paulo.Hi,
It seems that your configuration is Ok. By the way, the workaround for this error is:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Transparent gateway for ODBC][H001] The environment variable <HS_FDS_CONNECT_INFO> is not set.
* Set HS_FDS_CONNECT_INFO in the hs{sid}init.ora file to the data source name.
Example: HS_FDS_CONNECT_INFO = <ODBC DataSource Name>
* Make sure the hs{sid}init.ora file exists in the ORACLE_HOME/hs/admin directory and has the same name as the SID in the LISTENER.ORA.
Example: If SID=hsodbc in the listener.ora file, then the hs{sid}init.ora file would be named ORACLE_HOME/hs/admin/inithsodbc.ora

The system cannot find the file specified
I have tried from so many forms. This is so frustrating. Thank for everyone/anyone who wants to help. So this is what happened: I had to uninstall my previous sqlserver 2012(which worked great) for some reason, and I uninstalled everything from that download.
Then I installed the trial edition of sql server 2012 (64 Bit) and It wouldn't connect to the database. (Error mentioned above.) My local DB is COWBOYS. (COWBOYS is also my computer name.) After this, I have tried downloading sqlexpress and sqlserver 64bit
many times and cannot connect to my local DB.
How do I connect to my Local DB?
Also, I think this might help: (When I run sqlserve.exe, which I was able to find in C:\Program Files\Microsoft SQL Server\110\LocalDB\Binn, I get an error: Your SQL server installation is either corrupt or has been tampered with(Error getting
instance ID from name). Please uninstall then re-run setup to correct this problem.
I would happily re install it, if it wasn't my 20th time.
I don't have any remote connections, I don't use username/password, only window authentication. I work mostly on visual studio, but without able to store /retrieve data, I don't know how to survive.
May be the solution is very simple, but I am too frustrated.
Some of the things I have tried:
From a command prompt, enter one of the following commands:
net start "SQL Server Agent (MSSQLSERVER)" OR
net start "SQL Server Agent(instancename)"(for instance)
on my sql configuration, I cannot start anything because there is nothing there to start. I can post more details, if that would help. Also, some more details about the error:

Any one that can help me, I will be greatful. Thank you so much. p.s. please ask me anything if you have any questions.It sounds like there are a couple things going on here. First check if you have a successful install of SQL Server, then we'll figure out the connection issues.
Can you launch SQL Server Configuration Manager and check for SQL Server (MSSQLSERVER) if default instance or SQL Server (other name) if you've configured your instance as a named instance. Once you find this, make sure the service is started.
If not started, try to start it and see if it throws an error. If you get an error, post the error message your hitting. If the service starts, you can then launch SSMS and try to connect. If you have a default instance, you can use the machine
name in the connection dialog. Ex: "COWBOYS" where Cowboys is the machine name. However, if you named the SQL Server instance during install, you'll need to connect using the machine\instance format. Ex: COWBOYS\Romo (where Romo
is the instance name you set during install).
You can also look at the summary.txt file in the SQL Server setup error logs to see what happened on the most recent install. Past install history is archived in the log folder if you need to dig those up to help troubleshoot, but the most
recent one may help get to the bottom of it if there is an issue with setup detecting a prior instance that needs to be repaired.

I was following this adobe article (
http://www.adobe.com/devnet/dreamweaver/articles/php_macintosh.html)
to set up PHP and MySQL and connect a MySQL database to dreamweaver
in Mac OS 10.4.8 and I kept getting:
"Can't connect to MySQL server through socket
'/var/mysql/mysql.sock' ERROR#: 2002".
After a lot of searching I came across
this
article which said that there was an error in the PHP and MySQL
connection or something.
Anyway all I had to do was type (in a TERMINAL window):
$ sudo mkdir /var/mysql
$ sudo ln -s /tmp/mysql.sock /var/mysql/mysql.sock
and that fixed the problem, otherwise the adobe article
worked very well.

How to track IP's of clients connecting to DB server through Apps Server
My Application server address is like http://192.220.0.75:7779/forms90/f90servlet form=TEST.fmx&userid=@abc
I can connect to Apps server from any computer using explorer with this address .
for auditing when I connect to db server through Apps server then my audit table detect only server IP- 192.220.0.75 each time but when I connect by oracle DS or toad then my audit table detect each computers defferent IP address.
how can I detect different users and IP addresses connecting to database server using apps server instead of apps server IP?You can try to use WebCache event_log, this one will show your clients IP or you can uncomment UseWebCacheIP ON in httpd.conf file, so you ensure that the access_log show the ip of the user and not of the server.

IPhone connection with B1i Server through internet
Dear All,
iPhone is successfully connected with my B1i server through intranet (wifi connection).
But When i am trying to connect my B1i server through internet, I am getting the following issue.
I am getting an error as follows when i try to browse the tomcat homepage in IE
XCL198 HTTP-access currently not allowed from remote clients, as B1iP runs in local-mode or safe-mode.
I followed the solution given in B1iC troubleshooting Guide.
I am using SAP 8.81 patch level 6.
Maintenance->CFG Runtime parameters as
B1i Http port :8080
B1i Https port : 8443
B1i Server : My server ip
Please help me to resolve this problem.Ken, George, Dear all,
in given context of problems running the mobile solution, please do NOT change B1i server Xcellerator properties at all.
Quite frequently there are ideas to change the default settings of WebDAV and remote settings of B1i server. This is simply a waste of time and definitely not required for troubleshooting or making the mobile
solution working.
Simply check the documentation 'Administrator's Guide for the Integration Component' for the purpose, the default settings, and further info about these properties you instruct to change:
a) About xcl.http.localOnly
Administrative Web access is limited to the local machine only. After installation, it is possible to manually allow access by remote machines by changing the particular setting in the operating system configuration file
(Xcellerator.cfg).
For additional documentation, choose Start → All Programs → Integration solution for SAP Business One → Integration framework, and then choose Help → Ref 04 – Operations, chapter 6.2.
b) About WebDAV-based access
WebDAV-based access to BizStore content is disabled. SAP does not recommend enabling this kind of access for productive systems, as this is typically needed for development systems only.
For additional documentation, choose Start → All Programs → Integration solution for SAP Business One → Integration framework, then go to Help → Ref 01 – Dev Environment, chapter 3.
For checking the connectivity from mobile to server / excluding network issues, B1iP can definitely run in local mode. When calling the server from mobile, B1iP would give you a fully sufficient, proper
response:
SAP B1iP detected an error: Emitted HTTP-Code 403 - Forbidden
Internal Reason XCL198 HTTP-access currently not allowed from remote clients, as B1iP runs in local-mode or safe-mode.
- This is exactely the alleged 'error', Tamizharasi mentioned at the beginning. Behind the internet connection issue from iPhone to his B1i server (which was unfortunately not described at all) must have been a quite different root cause - changing xcellerator properties is unfortunately a wrong recommendation here in order to clear such general iPhone issue.
I am concerned here from security side, such settings may not be amended lightly, and lead the problem-solving in the wrong direction - beside your additional efforts.
We do recommend to keep the default values and undo such configuration changes again, if not needed.
For troubleshooting the mobile solution please check SAP note 1602674.
Best regards, peter -
Can I make another website using iWeb, and then publish it to a different server through the SMTP panel on iWeb, even though I have a website published on mobile me, can I just use the SMTP engine to publish a different site but to a different server, that's the question I'm asking. I'm hoping for a quick reply. Thank you for your time in reading this.
Yes. You can do it one of two ways:
1 - select FTP Server in the Publish To menu (click on the site folder to get to the options) and enter the FTP address, username and password and publish as you would if using MMe.
2 - select Publish to Folder and publish. Use a 3rd party FTP client like Cyberduck to upload the site files to there server using the FTP address, etc.

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The
server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26- Error:Locating Server\instance Specified)
How Can i solve this?1. Make sure SQL Server Service is running
2. If a named instance, make sure SQL Server browser service is running
3. Make sure SQL Server is configured to allow remote connections
4. Examine the SQL Server error log for messages confirming that SQL is listening on the expected network interfaces and ports
5. Test server connectivity with PING from the client machine
6. Test port connectivity using TELNET or PowerShell to the server and port (from step 4) from the client machine. For example
a. TELNET <server-name> 1433
b. PowerShell: 1433 | % { echo ((new-object Net.Sockets.TcpClient).Connect("YourServerName",$_)) "server listening on TCP port $_" }
7. Check firewall settings if step 5 or 6 connectivity test fails

Can't connect to Exchange2003 Server through WRT54GS (via wireless)
I'm having problems conencting to my MS Exchange 2003 server, from an Outlook 2003 Client, when using wireless on a WRT54GS.
Hard wired - works fine.
Wireless - connection times out ("unable to connect to exchange server")
I can browse the internet through the wireless conenction, download (legal) music, etc. Cannot use Outlook/Exchange.
I disabled the "firewall" features on the router. (block external requests, etc)
WEP is enabled.
The Router was bought about 6 months ago (original firmware)
any suggestions? anyone successfully using Exchange across a wireless conenction?first i'd suggest that you upgrade to the latest firmware....also open ports 443-447 under the port forwarding section of the router.
