Access the console VM series

I'm trying to access a Linux VM console, using ESXi 4.1 serial.  Since the 4.1, a virtual serial port can be added via 'connect via the network', and then we should be able to Telnet or ssh to access the console series of the virtual machine.  I heard that someone did so successfully, however, I couldn't make this work in my setup.  Can someone please share their story of success?

Also, I also notificed that there is a virtual series concentrator on the market, which is basically a Linux VM.  For now, I'm not this solution not only because it's thousands of dollars, but also should not be other characteristics of fantasy in addition access conosle series of the virtual computer.

I'm trying to do something similar (although I want to drive a kickstart installation), and depending on what exactly you want to do, it might be possible.

You can get the prompt to listen on the ESX host by specifying the serial port by using the network, a server, and having a URI of tcp://0.0.0.0:10000 port

0.0.0.0 is the generic address (i.e. all the IP address on the ESX host) and 10000 is the TCP port. Starting the virtual machine, it will bind to port 10000 and you can then connect from the ESX host with netcat (the "nc" command), or open a port in the firewall, and connect to the network.

Direct connection of the ESX host:

ESX # nc 127.0.0.1 10000

The open Firewall port and remote connection

ESX # esxcfg - firewall - o 10020, tcp, in, series

myhost$ nc esx 10000

It connects, but once you sign, you don't see any output. After the start of the guest from a picture ISO of RHEL and boot the kernel with the command line 'linux console = ttyS0, 9600' (to tell the kernel the serial console output), you can see the messages of the kernel for netcat startup, but you can not really do something like netcat session does not appear to pass over the keys like enter (I'm sure you can do it work, but I don't know how). You can work around this by changing the host configuration URI to serial port of tcp://0.0.0.0:10000 to telnet://0.0.0.0:10000 and by connecting to it with a telnet client.

Now you can usefully interact with the session of kickstart, but only * after * you include the serial console settings in the initialization of the kernel arguments.

To operate without intervention from the vSphere client, so it seems that you change the ISO boot to at least include the 'console = ttyS0, 9600' default argument.

It is a bit of a pain for me, because I expected to be able to drive the initial startup on a text interface without changing the ISO boot, since we use a wide range of distributions different kickstart based with different ISOs (don't ask...).

I don't know if this helps you, but don't forget that you can perform a kickstart installation on VNC. See the options "vnc" and "vncpassword" here:

http://docs.redhat.com/docs/en-us/Red_Hat_Enterprise_Linux/5/HTML/Installation_Guide/ch-bootopts-x86.html

Although you should always provide an IP address and the location of the installation media. Furthermore, anaconda creates a script of kickstart recording how the installation was made in/root/anaconda - ks.cfg.

Hope this helps.

  • Cannot access the Console remotely

    Hey guys, I'm new to VM Ware and has difficulties to access the console remotely, even if I can access the Web Access page very well...

    The error I get is:

    Unable to connect to the MKS: unable to connect to the host domain.com: no connection could be made because the target machine actively refused

    When you search for an answer to this, I found a post that said to ensure that the /etc/pam.d/vmware-authd has been configured correctly, as well as the/etc/vmware/config...

    None of these files/folders are there.

    That said, my host OS is (unfortunately) of Windows Vista, with VM Ware running on top of that, and now I am trying to get Fedora Core 11 to present itself as the virtual machine.

    Any ideas you can give would be much appreciated.

    Sorry, I did not myself clear - its port 902 on the host that you need to check that you can telnet to because the VMware console connections are made using the host (so that they can still operate even when there is no network in the comments, for example at installation time), not to the guest directly (for client firewalls are not the parameters used either for the console). I guess that 8333 is fine, otherwise you wouldn't be able to connect remotely to the web console.

  • Cannot access the console of EM on SOA Suite 11 g (404 error)

    I have installed SOA Suite 11 g on a new environment. The administrator of the server and the managed server (soa_server1) start without any error in the newspapers. However after getting started, I am unable to access the console business to http://Host/em because of the 404 handler. Interestingly, I can access the console of administration WebLogic at http://Host/console with no problems.

    I have installed SOA Suite 11 g before on my local machine and have never had any problems like this before.

    Is it possible to manually start to the top of the Enterprise Manager application? I've seen some advise in previous posts that mention the use of emctl (Enterprise manager command line control) However, this seems not applicable to the app of the MA that runs on 11 g WebLogic application server.

    Troubleshooting tips would be greatly appreciated!

    You can access the EM using URLs http://host:7001 / em.

    But for the MS to be present in the area, you must have created your model Enterprise Manager domain is selected. I think, you have not done this step. Log in to your administration of WLS Console, Access deployments. Find an application named em '. If she is not there, then this is the question.

    To get your domain extended with EM, follow these steps.
    1 shut down your servers in the field.
    2 call the configuration wizard ($ORACLE_HOME/common/bin/config.sh/cmd)
    3. choose the option Extend area. Select your domain.
    4. Select the model of Enterprise Manager. Complete the wizard.
    5. start your servers.

    Now, you will be able to access the MS using the URL above.

    There is no need of emctl in SOA 11 GR 1 material. From the server administrator will help you work in EM.

    Hope this helps!

  • Cannot access the weblogic Server console.

    Hello

    In my windows server 2012 I created the virtual machine using the Hyper-V Manager.

    In this virtual machine, I installed the weblogic Server 10.3.6. The ip address of the virtual machine is 192.168.1.9.

    In my virtual machine using localhost I can able to access the console. But when I try to access the console to another computer that has windows 7, cannot able to access the console.

    Check if the AdminServer is listening on all addresses to link or not?

    Can you try to set an IP address to your AdminServer as following in your "$DOMAIN_HOME/config/config.xml", and then try again

    
        AdminServer
        
          false
        
        7001
        true
        192.168.1.9   
    

    Still, if you face any problem, then it might be a firewall problem.

    Please, try the following on the remote computer to see if the port is accessible from the other box or not:

    From your windows 7 computer customer trying to see if this port is available or not on this IP address

    telnet  192.168.1.9   7001
    

    Also several times the IPv6 configuration can cause this problem, where can you try to start your WebLogic using the following JVM option:

  • Access to the Console of Administration Mapviewer 12 c problem

    I try to install and configure Oracle Mapviewer 12 c (v12.1.3).  The installation seemed successful, but after the installation, I am unable to access the Console of Administration Mapviewer 12 c.  The default is Admin Console URL http://[host]:[port]/mapviewer.  I can reach the URL using a browser (Firefox, Chrome, IE), but the admin home page will not appear.  The browser just "turns its wheels"as it tries to load the page. " The image below is from FirefoxClipboard01.jpg

    Looking at the console of the developer of the browser (press F12) while the page loads, you can see browse the page of connection repeatedly (see image below).

    Clipboard03.jpg

    My environment consists of the following:

    (1) server OS: Linux (RedHat Enterprise 5.11) x86_64

    (2) oracle Weblogic Server 12 c - distribution "Oracle Fusion Middleware Infrastructure"

    According to the documentation, Oracle Mapviewer 12 c requires specific dependencies that will not provide generic install Weblogic Server (i.e. , http://www.oracle.com/technetwork/middleware/weblogic/overview/index.html,).  Instead, you must use the "Oracle Fusion Middleware Infrastructure" distribution, installation of weblogic server and all the dependencies required.

    The distribution of Oracle Fusion Middleware Infrastructure has been downloaded from the Oracle ADF OTN download page or leave cloud of delivery of the Oracle software.

    -Oracle ADF OTN download page: http://www.Oracle.com/technetwork/developer-tools/ADF/downloads/index.html

    -JAR file fmw_12.1.3.0.0_infrastructure_Disk1_1of1.zip

    (3) oracle Fusion Middleware MapViewer Version 12 c (12.1.3)

    -downloaded from http://www.Oracle.com/technetwork/middleware/MapViewer/downloads/index.html

    -JAR file is fmw_12.1.3.0.0_mapviewer.jar

    Following the instructions in the for Oracle Mapviewer 12 c E29624-02 User Guide (http://docs.oracle.com/middleware/1213/core/JIMPV/index.html), first of all, I have installed and configured Weblogic Server 12 c, in Mapviewer 12 c followed.

    I made two attempts of different installation:

    (a) I installed Mapviewer using the Universal Installer

    (b) I have manually deployed an EAR MapViewer exploded in WebLogic Server folder

    Two attempts produced the same results.

    Specifically, after installation and configuration of Mapviewer, I could check the Mapviewer version using the URL:

    http://[host]:[port]/MapViewer/omserver?getv=t

    Immediately access this URL resulted in the expected answer text string:

    Ver12.1.3_B140430.1010

    I could also successfully access the Weblogic administration Console (http://[host]:[port]/console) and confirm the Weblogic is running, and that Mapviewer was correctly deployment up and running as well.

    However, at this point, if I try to access the Console of Administration Mapviewer 12 c via http://[host]:[port]/MapViewer , the Console launch page does not appear (as described above).

    at this point, I wonder why the Oracle demo site works (http://slc02okf.oracle.com) and me does not work.  I assumed that the demonstration site for the Oracle Mapviewer used Mapviewer 12 c.  I based this assumption on the fact of demonstration site for this Orqacle (http://slc02okf.oracle.com/mvdemo/demo/oracle_maps_demo_v2.jsp) displays a header SEO Mapviewer 12 c (see image below).

    Clipboard04.jpg

    However, when I questioned the version of Oracle Demo site URL (i.e. ) http://slc02okf.Oracle.com/MapViewer/omserver?getv=t ), I see that they run Mapviewer 11 g!

    Ver11_1_1_7_3_B140717

    So, long story short, deployed anyone successfully Mapviewer 12 c and if so, can you access the Console of Administration Mapviewer 12 c?

    Any contribution is greatly appreciated.

    Wayne

    Hi Wayne,

    Please check that Java is used to start the WebLogic Server. If the JDK 8, try starting with JDK 7 to see if the spin connection problem is resolved.

    Thank you.

  • Get the output of the console on Simulator BB10

    Is it possible to access the console (or at least the stderr) output a basic NDK application deployed to the simulator of th?  I tried telnet in the Simulator to run it, but the devuser does not have permissions on the files of the app.

    Or maybe is there a log of debugging as for Android?

    I would like if possible, avoid using the IDE for this.

    You don't actually run the console application, but you can use command line tools to look at the output of the application log.

    Basically SSH into it (it is not really Telnet) and navigate to the folder of the application under the/accounts/1000/appdata /... then run "tail-f newspaper/journal" after the launch of the app, or just "cat/journal of newspapers". If the output you are interested is no longer attend balls/journal because of the new substance slogger2, you would use a variant of 'slog2info w' instead.

    You are quite correct that attempting to run the application from the console did not give him the same environment and except in a very few cases, it serves no real purpose.

  • Access exclusive console?

    Is there a way to make the console access to a virtual machine that is exclusive to a single session? In other words, if I use the console on a machine, can I lock others go spy on it or support?

    These other users should always be able to access the console when not in use.

    Use the RemoteDisplay.maxConnections = 1 option (in the VMX file) advanced.

  • Unable to connect to the console of OAM11gR2

    Hello

    I just installed and configure webgate for OAM11gR2 and was able to connect to oam console with default credentials. Later, I changed the settings to store user to the store of the OID and define a user as an admin in the console of the OAM. Later when I try to access the console of oam with the new user credentials he says username and password incorrect. But when tried to connect from the user weblogic default and password, I get a permission error screen that says access denied - access to the administration console is limited.

    Please sugggest.

    To resolve this problem, do the below.

    (1) connect to the weblogic domain OAM console.
    2) click Lock & Edit
    3) go to the summary of the security areas > myrealm > suppliers.
    (4) select IAMSuiteAgent
    (5) delete.
    (6) save & activate the changes.
    7-restart the servers Admin and OAM.

    You should be able to connect to the console of the oam now. You must ensure schema LDAP is your identity store OID under the Access Manager settings--> Modules for authentication--> LDAP--> LDAP Authentication Module.

  • Unable to connect to the console of the virtual computer after dns change

    I finished just change of my VM and VC servers esx hosts to use the new dns servers. In addition the area changed as follows

    from vm1.subdom1.xxx.com to vm1.subdom2.xxx.com the esx hosts and vCenter server all underwent this change at the same time although ip addresses have remained the same.

    In vCenter but I do not see "cannot connect to MKS: address for server vm1subdom1.xxx.com host lookup failed: no host is unknown.»

    If I log into the esx vSphere Client with server can't connect to the console where I can say vCenter to use the new name of the virtual machine instead of the old host? I can ping and resolve the vm from the vCenter server and RDP to DNS so it works but vCenter is still going to the old address.

    Any help?

    To access the Console of the virtual machines... the vCenter does not really rely on the DNS config. It communicates only through ports 902/903

    This problem could have arisen due to some misconfig while changing the DNS... .pls try below
