Clients connection to Server

Hi all,
At one of client installation, I am required to every time use change server and give server ip address.
Whenever I login next to SAP B1 2007 B, it will not display company list, and I have to use Change server option everytime and change it to server ip from (local)
Can anybody tell me what I have to verify and change so that at Client PC SAP permanantly remembers the Server IP/Server Name
BR

Dear Samir,
In order to try to resolve the issue, please do the following steps :-
1. Go to Add/Remove Program --> Uninstall SAP Business One Client.
2. Go to C:\Program Files\SAP, then take a backup of the SAP Business One Folder and
    then delete the SAP Business One folder.
3. Go to Start --> Run --> %UserProfile%\AppData\Local\SAP\
    Then delete the SAP Business One Folder.
4. Now reinstall the SAP Business One Client application from the B1_SHR.
Now you can login and enter all the details information and then log out from SAP Business One
application. You can open the application again and check this issue.
Note : Please make sure that the Windows user has read and write access to the above two folders
          as per step (2) and (3).

What privileges for the DB account used by client connect to server?

Hello, After I installed the SBO server packages, I found that it must set DB account in the client side.
I had tried 'sa' account, it works. but I thought we should not leave the super account in each client side.
So I want to know what privileges should be assiged to the account in SQL Server?
Or somewhere already have documents to say how to build up the client account.
thanks.

[Solved] MPD clients connect to server too long first time

When my system start mpd clients cannot connect to server a long(10-15 seconds or more) for some reason.
Same time internet connection and network seems to be ok.
So, It's look like I run mpc for example and it get stuck. This problem is new. 2-4 weeks or less.
I've tried use user and global config without any success.
Mpd config now look like this:
music_directory "/home/neg/music"
playlist_directory "/home/neg/.mpd/playlists"
db_file "/home/neg/.mpd/mpd.db"
log_file "/home/neg/.mpd/mpd.log"

My netctl profile looks like this:

System start looks almost normal. USB reinit after uefi takes a lot of time sometimes, but it's not critical.

List clients connected to server

Is there a way to list the number of Clients connected to a Server?
Also, how can two Clients talk to each other using the Server as their mediator?
Example: Client1 sends "Hello Client2" to Client2 via the Server.
Client2 sends "Hi there Client1" to Client1 via the Server.
Thanks

Well, you wrote the server?
If so, then you can add code to the server to keep track of all the currently connected clients. You might wish to store them in a Set or a List or a Map. And you can add code to print the contents of that Set or List or Map.
For the second part, just like the first, it's a rather broad question. "How" to have them talk to each other? You need to define your requirements. For instance, will there always only be two clients, and they just talk to each other? Or could there be any number of clients and any one can talk to any other, lik with chat? What part of what you want do you not understand? The basic idea is that the client sends to the server, and the server forwards on to the other clien. I don't really know what you're asking.
You might try googling for java chat code or something. I'm sure you'll find lots of samples.

Blocking client connection, if server down

Hi,
is there a way for a client connection (an io socket, not by using nio channel) to block for a server, if the server is currently down?
Thanks

There's much more to this than the OP realizes:
1) if the server is down before the client could establish a connection,
the client has to keep retrying to make a connection.
2) if the server goes down while the client was waiting/reading for some
data, the connection is lost, the partial data must be kept or thrown
away depending on the communication protocol and the client should
repeat step 1) again.
3) if the server goes down while the client was writing to the server, the
write fails and the entire shebang should be restarted at step 1) again.
Personally I wouldn't bother and simply spit out a "connection lost,
please try again later" towards the general direction of the user.
kind regards,
Jos

Callconnector advanced client connects to server only randomly

Hi,
I just installed scc server and 20 call connector advanced clients at a customer site. Everything worked on the installation.
Installed all the licenses ok.
I just received the following email from the client:
"A number of staff including myself are experiencing difficulty logging on to the Cisco Smart Call Connect system each morning. When we try to log on we get a message saying network error as the systems goes through the motions of trying to connect. After the systems has made 5 attempts to log on a message box pops up saying unable to connect to server. We are trying all the usual solutions to correct the problem ie. Restart and shut down etc. This is successful only sometimes and often we have to try several times. One of our ladies in the Accounts Department, Sally Pan has tried 4 or 5 times this morning to log on and is still unable to connect. In my case today after the 4th attempt I was able to connect."
The call connector server is always on and is installed on a win7 32bit 4gb ram system with static ip.
I can not see why would this happen.
How should I proceed troubleshooting this issue?
Another question: The callconnector advanced clients installations are on PCs that get ip address via dhcp. I know I had to input the ip address of the pc when I installed the advanced client. Does this have anything to do with it (i.e. does advanced client need to be installed to a pc with statically assigned ip address, or it does not matter)?

Anthony,
It helps if you state what product and what version you are using. It appears as though
you are using Java System Message Queue. If so you need to set the
imqBrokerHostName attribute on the ConnectionFactory (imqAddressList is also
supported on later versions). See the Java Client Developer's Guide:
http://docs.sun.com/app/docs/coll/MessageQueue_2005Q1
A quick way is to pass the property on the command line:
java -DimqBrokerHostName=yourserver . . .

Hi Hasan,
Firstly, please make sure that the software is compatible with the Windows Server 2012. Have you updated this software to the latest version?
Secondly, please check if the software is listening on the proper port. To verify this, please use the command below:
netstat -an
Also, please disable the firewall and try again.
Best regards.

Non-Domain joined clients connect to server initially but cannot connect via Launchpad

Running SBS 2011 Essentials in a small office. Running XP/Vista/7 clients. All working fine until we swapped routers. Old router died, new router was installed.
Now all domain-joined PC's connect as normal, but all NON-Domain-Joined PC's cannot access the server via the launchpad. I get the "The server appears to be offline. Do you want to sign in to offline mode?" box.
Tried removing PC from the SBS Dashboard, uninstalling the connector from the client, restarting client, and reinstalling the connector. I can install the connector (using
http://<server ip>/connect , but not http://<servername>/connect
). Connector installs but it still tells me the server is offline when trying to use dashboard or launchpad on the client.
Note: I can add a network location or Map a network drive to ther server after inputting my network password from Windows.
Any Services to check? Firewalls exceptions to ensure? Advice?
EDIT: Dashboard on Server shows Client, sometimes as online, sometimes as offline.

Sounds like name resolution issue to me.
Are all your clients set to use the IP of the Essentials Server for their primary DNS?

Clients connected to server freeze after while

We have a XServe an several Mac and Linux clients. The xserve mainly hosts the user directories (via afp for Mac- and NFS for Linux-Clients). In addition web-services and the iCal-server is running.
Everything was running fine for weeks. But recently I encountered a strange problem:
After working on a mobile account for a while (on a MacBook Pro) the machine becomes totally unresponsive (Beach-Ball-Everywhere). The Dock sooner or later always completely freezes. If I try to start an application like Terminal.app from the Dock (before it got frozen) then the icon gets an question-mark. All this happens on different user accounts.
This is completely strange as everything was working fine for quite some time. I am most interested in two things:
1) has anyone encountered any similar symptoms?
2) I am not quite sure, but maybe the trouble started after I added a SSL Certificate (but that's just an assumption)

Of course I can not say for sure that it is no hardware defect but honestly I do not think so. Right after I posted my problem I disabled SSL for Open Directory (via ServerAdmin). So far everything works fine. So could be that this was the source for the problem?
At the moment I don't see an alternative for searching the problem by trial and error. My biggest hope is to find somebody with a similar problem.

Receive email delay one hour using Mac Mail client (Mountain Lion) connect Exchange Server 2010

Hi all,
My boss use iPhone, iPad, MacBook Air (Mac Mail client), MacPro (Mac Mail client) connect Exchange Serve 2010 to receive emails. All clients are okay except MacBook Air, the Mac Mail client cannot receive the latest emails from Exchange Server, but it can receive (sync) the emails after one hour. The other clients can receive the latest email after Exchange Server receive new emails immediately.
In this period, the MacBook Air can receive the other IMAP, POP3 and webmail from ISP normally. I tried to set 5 mins to check emails or manual check email from Exchange Server. However, the latest email still delay one hour.......... .
I dumped a screenshot for Mac Mail setting for Exchange Server and a Log file.
could anyone help me to solve this issue?
Thanks

I am not sure what the user has the check for new messages set for but mail does arrive as short as 2 minutes. It does however arrive on his iphone immediately first.

Different client connect server but get same IP??

    }please help.. thanks

hi, thanks for reply.
yes, i am trying to connect from different macnine
that have different IP address.
how to check if it asign same external IP toclient?
can it be configure to assign different IP?what he means is, if you run your server at location
A, and all your clients from location B, with the
internet in between, and a single router/switch
serving internet connections to the clients at the B
location, then the server at the A location will see
the external IP of the site B router, not the
individual IPs of the clients behind the router
(since those IPs are only for internal network usage
behind the router)
in short, do you test with multiple clients from one
internet connection? then it would be logical that
they present the same IP to the server. The best (and
most realistic) way to test would be with multiple
clients from multiple locations / internet connectionsok.thanks.
so is it possible for me to get the client machine ip but not the IP for the router? because i will hav multiple user from same location access the server at the same time.

Disconnecting clients from Streaming Server

Hello,
We have Streaming Server installed to stream online-seminars to the clients. We want to manually disconnect some clients during the translation while leaving others online. What is the way to do it? Clients connect to server by opening a web-page on the other web-server with embedded flash player which has the source streamer uri rtmp://our_server/live.
Thank you,
Olga Butygina.

Спасибо за ответ!
У нас как раз php-сайт c данными о клиентах в mysql, так что предлагаемый вариант - то что надо. Одна проблема: мы используем уже готовый плеер (http://www.longtailvideo.com/players/jw-flv-player/) и не задумывались о разработке собственного флэшового плеера.
Разреши задать тебе пару вопросов.
1. Такой плеер, способный общаться с php-сервером, можно написать на Flex в свободном IDE или же требуется Flash Professional? Насколько я знаю, во Flash уже есть готовый компонент FLVPlayBack, можно ли без него обойтись во Flex?
2. С помощью Loadvars можно также посылать серверу информацию о запуске проигрывателя для пополнения счетчика просмотров или есть более простой способ внедрить такой посыльщик запроса в обычный swf, содержащий видео?

Hi Jason
I was getting the same behavior after Apple support had me delete some plist files to get Airplay going. I was also getting the following error:
the error occurred while processing a command of type 'writesettings' in the plug-in 'server vpn'
I went into ~/Library/Preferences/ and /Library/Preferences/ and deleted every plist contating the word server. I had to re-set up my server (meaning walk through some intial steps) but all of my settings were still there after that and everything started working again.
Just a thought, obviously try at your own risk but it worked for me.

How to make the client connect to the server at the command prompt?

I found this code on IBM's website, it was a training session on servers and clients using java.
The code compiles fine and the server seems to start up properly when I use java Server 5000. I think whats happening is the server is running and listening for a connection on port 5000.
When I try to run the client I get the following error.
Exception in thread "main" java.lang.NoSuchMethodError: main
I see a start() method but no main. As far as I know, applications should all have main, it seems as if the person who wrote this kinda confused applets with application. Not that I would really know what happened.
If you have time, could you tell me if there's an easy fix for this? I would love to have this client/server working if it isn't too much trouble. As I have looked all over the net for a free client/server applet that will actually let me see the java code and none of the free ones do allow getting to their source.
Most of them allow you to customize them somewhat but also have built in advertising that can't be removed.
This is the closest I have come to finding one that lets me look under the hood. But alas it doesn't work out of the box and I don't know what to do to fix it.
Heres the code: Server:
import java.io.*;
import java.net.*;
import java.util.*;
public class Server
// The ServerSocket we'll use for accepting new connections
private ServerSocket ss;

ORA-03113 while connect from 8i client to 7 Server

Hi,
I have a Oracle 7.3.3 Server running on a SCO OpenSever 5.0.5 and a Oracle 8i Client 8.1.6.0.0 on a RedHat Linux 6.2.
When I try to connect from the client to the server by issue command "sqlplus user@test", it responses me "Error while trying to retrieve text for error ORA-03113". But when I run "netasst" to test the connection, it says the connection was sucessful.
Can anyone help? Here are my configuration files:
Listener.ora on Server side:
LISTENER=
(ADDRESS LIST=
(ADDRESS =
(COMMUNITY=TCP.world)
(PROTOCOL=TCP)
(Host=10.128.64.52)
(Port=1526)
STARTUP_WAIT_TIME_LISTENER = 0
CONNECT_TIMEOUT_LISTENER = 10
TRACE_LEVEL_LISTENER = OFF
SID_LIST_LISTENER =
(SID_LIST=
(SID_DESC =
(SID_NAME = test)
(ORACLE_HOME = /usr/app/oracle/product/7.3.3
(PRESPAWN_MAX=10)
tnsnames.ora on client side:
TEST.888.COM
(DESCRIPTION =
(ADDRESS_LISTS =
(ADDRESS =
(PROTOCOL = TCP)
(HOST = 10.128.64.52)
(PORT = 1526)
(CONNECT_DATA =
(SID = test)
)

Hi,
I don't have a 64 bit instance, but maybe another test will be usefull, try to get a connection with sqlplus on the server but via sqlnet like "user/passwd@tnsentry" I think if that also is not possible it is not the 64 bit issue but more that the listener itself coundn't etsablish a db connection, be aware tnsping is only testing if the listener is running and do not check if the listener is able to connect to the db.
Hope this helps a little to find your real proble ;-), Olaf
