I am biginner with tryton so accept my request. My situation is: I install a tryton server in my remote server production and I install my tryton client in my localhost. My question is: can I connect to the remote server with my tryton client? if yes. I need to know how to do this. Many thanks in advance.
Yes, you can connect to a remote server. Thinks to take in account:
Your server should be configured to listen to public ip. See http://doc.tryton.org/3.6/trytond/doc/topics/configuration.html?highlight=listen#listen
Ensure that there is no firewall blocking communication
Once done that, you can connect to remote server introducing the host and the port of the server in the client dialog. Have a look at:
http://tryton-documentation.readthedocs.org/en/latest/user_guide/tryton_client.html#connecting-to-your-server

I want to integrate service on my website, but the requirement from the service provider is that, data transfer must be performed using Tunneling, could you tell me detailed process how to connect remote server and send requests there. I have all credentials: remote server IP, ISAKMP key and stuff like that.
I tried configuring strongswan on my VPS, but I was not able to complete process due to some errors.
Good afternoon in my timezone.
I am developing a web appp in J2EE.
This web app is called and access inside a sharepoint portal.
When i enter through the sharepoint portal i can access my application, using chrome developes tools i can see all the HTTP traffic, and i see that the browsers sends a request to the following server that is where my app is running serverprd.enterprisename.com.
But when i use the command line in my windows 7 , to ping the machine(server) , for example :
ping serverprd.enterprisename.com it returns me the following message:
"Ping request could not find host serverprd.enterprisename.com"
I am using a proxy.
Can anyone tells me why this happening ? Why through the browser i can access the server and the ping command does not find me the server ?
With the best regards.
Thanks in advance.
Your proxy server id the one who have an access to outside world. All http requests are sent to proxy server and proxy server does DNS lookup. In case of pin, your host have to do DNS lookup and this operation obviously now allowed ( firewall or so).
Why I am not able to connect to remote server from asp.net website whereas it is connecting from SSMS
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
I tried all the possible solution suggested in this link
I checked Followings as given in the above article, they are enabled/running
SQL Server is up and running.
TCP/IP enabled in SSCM
Opened port in Windows Firewall
Remote Connection enabled
SQL Server Browser Service running
I searched for sqlbrowser.exe but it is not found in the given directory.
Finally I switched off Windows Firewall but still it is not working.
UPDATE: we are connecting to sql server using a custom user created on sql server (not sa )
I have user account credential to Remote connect to server.
I tried to change LogOn to my credentials (administrator) . in Windows Services SQL Server (MSSQlServer) and SQL Server Agent (MSSQL Server) services.
Double check your connection string - are you connecting to a hostname that needs to be added to your Hosts file? For example "dev-sql1" but without a matching entry in dns or hosts file.
If you have created a custom user, can you check if logins are disabled for the user?
In SSMS, goto Security, right click user, Properties -> Status, Login - Enabled.
Hope this should fix it.
Three possibilities and they are not mutually exclusive.
Most hosting providers disable remote connections to SQL servers. Check with RackSpace if blocking port 1433
The SQL Server needs to be reconfigured to accept remote connections. See http://support.microsoft.com/kb/914277
You have to use a different connection string. See http://www.connectionstrings.com/sql-server and look for Connect via an IP address
I got the same issue but with mysql server. Rack space had two mysql server address. One for connecting from outside their local network and one for connecting from inside the network. you will have to use the address that is required to connect from inside the network.
I have problems connecting to my database server. The database server is not local, I am connected via its IP address.
It works fine in my development machine. After publishing the website to my server, it can not connect to my database server.

Why can't my publish server connect to the database server, whereas it works fine through the development machine?
I often had that problem. Mostly it's because of two problems.
Open the SQL Server Configuration Manager.
Check if the SQL Server Network Configuration supports TCP/IP, if it's disabled, enable it.
e.g. SqlServer 2005 Network Configuration, Protocols for SQLEXPRESS
Open the SQL Server Management Studio
Click on the Sql Server Properties (right click on the server name and
select properties).
After that, select the page "Security" and switch the check to "SQL Server and Windows Authentication mode".
That's all.
I'll attempt to go two for two on the psychic debugging for today...
I will assume that you are not using integrated security? If so it might explain things as the account on your local machine probably has permissions, but the SYSTEM account that is running on the server does not. Just a shot in the dark though.
It sounds like your server can't make the network connection, rather than a security issue.
Ensure that any firewalls on both the DB and app servers allow traffic on the port (1433).
Ensure you're able to ping or tracert from both machines.
Is it your first time you publish your website on the web server ? if it is , Are you sure you have set your connection string properly ?
You need to create a login ( of curse a password for that too ) and the IP Address of that SQL on the web server .
So you need IP Address of the sql server host , Database Name , UId , Pwd .
I will agree that this sounds like a network issue and not a security issue.
Remote into the web server and ping the DB server by IP address. If this does not work, your server cannot see the DB server via that address (different subnet, incorrect firewall/proxy setup, etc). There may be a proxy address you must use to get to the DB server from the web server, or your web server may also be the gateway and IIS doesn't know to look for the DB server on the LAN. If it does work, the computers may not be talking on the same port, or the firewall may be blocking that port exiting the web server.
I have spent hours trying to connect to SQL server using sqlcmd. I disabled my firewall, checked all ip listed in "Protocols for SQLEXPRESS", edited my hosts file. I tried using different ips and machinename to connect to the server. But none of work worked. After hours of investigation, I found out that I made absolutely stupid blunder making me unable to connect.
I want to remind people that the connection string is not case sensitive. But the option is!!
what i did is I put
sqlcmd -s .\sqlserver
But the correct string is
sqlcmd -S .\sqlserver
so watch out, people
I was wondering if there is a way to see if a server blocks outgoing connections. I am trying to connect to an external database from a client's server.
This is the error I get:
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: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)
Edit:
I forgot to say I only have access to the plesk control panel. That's why I was asking if there is a way with asp.net.
When you say "server", do you mean the asp.net server, or the SQL server? And are both machines on the same network? Is this hosted?
Sql Server:
They can remove the OPENROWSET functionality, so you can't connect to remote servers, regardless
I doubt they are giving you access to linked servers in a hosted env
ASP.Net
You can try to connect to the other server via a regular connection, and see if that works.
Download a tracert component, and use that to try to trace from your server to the remote one.
If it dies somewhere inside your network, then that is your answer (it is blocked)
If it works, the outbound is open. Doesn't mean 1433 is open though.
If it dies after, not blocked, but maybe the remote is blocking icmp echo
Remember to try to tracert to somewhere else that you know works
It will be hard to tell what is killing the connection on 1433, if you can get to the server using other means. Could be the firewall, their fw, etc.
The trusty telnet method:
telnet theserver 1433
If this times out, the server is not listening. If the screen blanks and you can type something, the server is listening and no firewall is blocking the connection.
In Vista and Windows 7, you have to install telnet as a Windows component from Control Panel -> Programs and Features.
