connectivity from client to client on ASA5520 RAS VPN

• Client VPN blocks inbound connections from remote desktop?

  I am running Vista x 64. To connect to a VPN Windows via the built-in VPN client works except that it seems that all incoming connections from the local network (including remote desktop) are blocked.

  Is this a known problem or design? It is a problem for us because the computer that is running the VPN client is a virtual machine running in hyper-v, so accessible by users via remote desktop - only connection to the console of the hyper-v Server is not an option.

  Are there alternatives?

  It sounds like the question to split the tunnel . On the VPN client you can enable/disable split tunneling. See this article for help with that.

  Note the security ramifications...

  In addition, I can not comment on this issue and a virtual machine, so as always YMMV...

  Hi all

  I got a requirment, it is the flow of Muliticast need access via RAS VPN

  Scanario: I have ASA 5540 peripheral, configured profile RAS and user that connects to the ASA device to the standard access via VPN server.

  We have now posted on the Web and flow need to access the profile of RAS VPN PCF. Please let me know is technically possible to configure configuration mulitcast and is the machine of the client user can access flow via VPN. Help, please

  Unfortunately, this is not supported with the customers of the software.  You need a router IOS any if you want to multicast via VPN.

• Client connections from linux on Solaris failing DB server

  Hello

  I checked a lot of things online. They all said.
  1 check your service Listner
  The listening service seems to be very well because I ca connect using the listner of my box Solaris SPARC local as well as another Soalris SPARC box that has a client for oracle 10 g
  
  2. the process boundary must have been saturated.
  However, this isn't the case either I checked the view v$ resources limited and confirmed, I have also increased the number of processes
  
  However when I do a TNSPING to my linux box using the name of the DB to Solaris, I am able to get a ping successfully.
  
  I need your help to fix it.
  I guess the Oracle client and DB server can be on a heterogeneous distributed system?

• LabVIEW - Arduino TCP/IP, connecting multiple Clients

  Hello

  I'm working on a connection TCP/IP between an Arduino shield WIFI control with several sensors and a LabVIEW program. You use a router, I set up a wireless network without internet that allows me to transmit the readings from the sensor of the MCU and send commands to control LabVIEW program. Currently, the Arduino is the server with the program LabVIEW connects to it as a customer and I would like the opportunity to add other clients such as a smartphone application at the same time. I am not able to connect several clients for my server Arduino based and wonder if and how this would be possible if the server was created on my computer using LabVIEW instead.

  I searched for help on the Arduino forums (http://forum.arduino.cc/index.php?topic=268578) and comments ranged from "Arduino can support multiple clients" to "Arduino can support multiple clients but it is full of errors. While it would be easier to achieve my goals by having the server on the MCU, as much data would be sent directly to each poll, the client I plan to switch to a server on computer using LabVIEW. My question is whether it would be possible to have multiple clients access to my new server, and if so, how it would be difficult to relay data from the sensor? The old plant requires the same data string for each client connected to my server. The new configuration appears as it would take the server to treat customers differently; Send commands to the MCU customer and data of the sensor of the MCU customer to everyone. Another layer of complexity is that I would need to relay controls of other clients in the same way, as the phone app smart sends a stop test command, to the Arduino via the LabVIEW program.

  Would be very grateful of entry to the community.

  Best,

  Yusif Nurizade

  You can create a server in LabVIEW that accepts connections from several clients. There are examples of different approaches to this in examples of shipment of LabVIEW and on this forum. As for the challenge of sorting where to send the data and how to transmit orders, it is-there is nothing that would make whether easier or harder in LabVIEW that in any other environment.

• Connect OBIEE client windows to Linux VM

  Hello

  I installed SampleAppv506p running on a Virtual Machine on my windows PC. I want to connect to OBI in the virtual machine with windows OBIEE from my PC client.

  I need to establish an ODBC connection for that, but do not succeed.

  Try it with my PC telnet to the virtual machine also gives an error.

  Telnet 10.0.2.15 9703 = > connection to 10.0.2.15... Could not open connection to the host, 7780 port: connection failed

  I get the same error when you try: telnet 127.0.0.1 9703

  I've already searched Google and tried/checked:

  -> When I start the virtual machine and then I get the message "IP address of this machine is: 10.0.2.15."

  but in/etc/hosts, I have 2 lines:

  127.0.0.1 demo.us.oracle.com localhost locahost.localdomain demo

  10.0.2.15 demo.us.oracle.com demo

  (I tried to comment on the first line, but it is added after the virtual machine restarts. Probably because I have 2 NICs - NAT & Bridged - in the virtual machine settings).

  -> Running ifconfig in a telnet in VM window gives

  eth31: no adr inet

  eth32: addr:10.0.2.15 inet

  Lo: inet addr: 127.0.0.1

  -> in the VM: localhost:7001 / em

  I see that BI server works with the following ports:

  -BI Services presentation: 9710

  -Servers BI: 9703 (it is the one I should use for the ODBC connection?)

  -Planners BI: 9705

  -Controllers of BI Cluster: 9706

  -BI JavaHosts: 9810

  -> I also turned off firewall in the virtual machine:

  service iptables stop

  chkconfig iptables off

  10.0.2.x is the NAT address, then you won't be able to connect to the windows host.

  I always run VMs with two NAT (for outgoing internet access to comments) and host-only (for guest conductor communications).

  

  If you use bridged it relies on reviews (sampleapp) access the LAN that your host (windows) is activated, such as wifi. This works sometimes, but can add complication - where the advantage of the network invited only.

  As gianni says won't play with the files/etc/hosts, will only end in tears

  I will try:

  1. Add a host only (or replace one bridged) network adapter. SampleApp to restart and you should get another IP address which you can connect from your windows host
  2. To the contrary/as well as the above, you can configure Port Forwarding on NAT for the OBIEE ports adapter (9703, 7780, etc.). This guide looks like a pretty good. Once it is set, you point your Windows machine (admintool, web browser, etc.) to the address localhost (Windows) and virtualbox port forwarding redirects the traffic (and answers) to the ports concerned on the guest VM.
     Host only is certainly an easier place to start!

• Wait events, SQL * Net message from client

  Hi all

  I have a doubt about oracle wait events, specifically of "SQL * Net message from client. I've read a lot about this, I've seen some say that network and other material resources can provoke him, and saw that the problems in the application code can cause it too. I am tracking a few tests here and I don't have that chooses are the double event, usually a lot of SQL * Net message to client waiting (I used sqlplus, developer sql and pl/sql). Can someone explain to me why? Another question is where this wait type cause interference, meet it demand for the database and stays on hold and do not meet another request so that the wait is over, is it? The waiting just finish when the application closes the database connection or there is another way to end the waiting?

  Since then, thank you very much.

  Hello

  chooses double what usually causes a lot of SQL * Net message to client waiting

  Do you run them from your server applications or from the DB server itself?

  "SQL * Net client message" is an idle wait event although he'd still explain to the elapsed time of the query.

  It indicates only that the database is waiting for the other entries of the customer and when he expects the DB, those expectations get incremented.

  I suggest you explore size SDU, RECV_BUF_SIZE, and SEND_BUF_SIZE parameters.

• Establish a persistent connection between client and server

  My application must keep in touch with my servers, the HTTPConnection gives the ablitity to make one request per connection. Then the HttpConnection might not make persistent connections in the BB. I think I can use Socket connections. I am wonding if some body can confirm that and give some sugustions how persistent connections between clients and servers.

  I have a problem loading data through Php in Oracle: web page of Php open an xml file, create a .csv, then begins to Oracle using an external table to process the data.

  The problem is that, the second time that PHP is trying to run the following query:

  INSERT INTO table1 T (Field1, Field2, field3, field4, sphere5, case field6) VALUES ('Aaa1E63819707', SYSDATE, 'KO', 'error', 'L', 'file_name.xml') POLL INTO Field1: id

  on the Oracle sessions, I have an exclusive lock on table1 and wait for SQL * Net more data from client.

  Where is the problem?

• Failed to connect to client host vsphere and Vcenter also esxi.

  Hi all

  I am trying to connect to the ESXi 5 of vsphere client host. I get the error message:

  vSphere client cannot connect to < ip > an unknown connection error has occurred. (The request has failed because the remote server has taken too long to respond. (L'opération a expirer)).

  and of VCENTR I am trying to add this host. I get the error. Of"request timed out".

  I can connect to the shell of ESXi and restart the vpxa services and spend. I can ping to esi IP host. but just cannot connect to it.

  earlier, he the host showed as disconnected in Vcenter. I tried to plug it failed. so I took it off I think can re add back. It did not work.

  I can just connect to client as esx host.

  kindly advice.

  Thank you

  Hello

  I am able to connect now.

  I noticed as I said previously, unable to connect to the localhost error when running esxcli. Unable to connect using the vsphere client. Unable to connect using VCenter.

  So I started to dig that's wrong with the OS esxi. and began running a few commands information esxcfg etc file system use of space, inode inconsistency, a few other commands such vdh, df to check the file system.  . and but has not changed anything. network configuration is correct.

  in these I run services.sh reboot, restart vpxa, pass reboot, restart host, check the logs, vmkernel, vpxa newspapers spend., check the date and time of the host.  I couldnot Firewall check since esxcli did not work. I haven't checked listed above step on the SSO.

  If you type esx and double tab, you will see many orders. I started testing on these orders.  so esxcli was a single command I tried later. It worked all of a sudden.

  Once esxcli has started working, I checked vsphere client to connect to esx host that it worked. then I was able to connect in Vcenter also.

  Thank you for your support

• SQL * Net more data from client wait event

  Hi all

  DB 11.2.0.2

  AIX 6

  I get two events of high expectation of the AWR report page

  (1) SQL * Net more data from client

  synchronization of log files 2)

  Need advice to the configuration of the hardware and network latency?

  What should I do for the first event of waiting?

  This simple average may, what they're doing massive data loads with a very large table size that the Oracle Server manages very effectively but necessarily expect much coming data of the customer and parallel large log files written to end on the validation.  It is possible that setting a large SDU and tcp large transmiat and receive buffers would help if this happens to be what they do; Similarly, if that's what they do, then reduce their size of table can also have some effect.

  Hello. No explanation for this... :-(

  Hello

  people work here, you don't know?
  I think Tom Kyte explains it well enough. This wait event is linked to your session database waiting for the guest to say to do something.

  So it is not related to the database, but to your application.
  Also as it is a wait of session event you might have had your session inactive for some time (do nothing)

  If you want to check the waiting events correctly I suggest using tkprof and start a new session in SQL more as shown by Tom Kyte in the link I posted.

  Then, run your query in sqlplus setting track and pull it out as soon as your statement is completed.
  that is to say:

  -- myest.sql
  alter session set events '10046 trace name context forever, level 12';
  SELECT ... -- your query here
  exit
  

  Run in sqlplus in this way:

  sqlplus user/password@db @mytest.sql
  

  Then check with tkprof.

  Kind regards.
