how to disbale this permenanlt?
how to configure FTP in linux server?

Hi,
If what you need is copying files between systems and all have sshd, you can use scp and it won't ask for a password if keys generated in machine1 from the user that will make the connection are trasfered to machine2.
You can try following this tutorial Link: [http://enrique.barbeito.org/blog/ssh-sin-contrasena/] It's in spanish but I think it's easy to follow; it's the one i followed to avoid password between some of my systems.

  • Ports required for communication between Web servers and service applications (the default is HTTP)

    We're using SharePoint 2010, I'm the system admin for a SharePoint farm. We enabled SharePoint Search by adding a Search Service APplication. One of the crawl report timer job is failing every 5 minte with the error "Cannot connect to remote server".
    After digging around, we found that the server running the timer job tries to connect to the SearchAdmin.svc on the index server, over HTTPS / port 32844 However, communication over SSL via a non default port is blocked by our firewall.
    According to this article: https://technet.microsoft.com/en-us/library/cc262849.aspx the default is HTTP for communication
    between web servers. How is it possible that it's trying to connect over SSL?

    Hi,
    Quoted from
    https://technet.microsoft.com/en-us/library/cc262849.aspx#ServiceApp :
    You can change the protocol and port binding for each service application. On the Service Applications page in Central Administration, select the service application, and then click
    Publish.

  • How to use Wallets for FTP Adapter

    Hi,
    Can someone point to a document that shows how we can make use of wallets for FTP Adapter.
    Thanks

    Hi,
    When you configure the Connection Factory for FTP Adapter in Admin Console, provide the following values for the attributes like the hostname, username, password, port and the path of remote location as where
    you want to write the file in remote Server i.e., ftpAbsolutePathBegin. Please fill this
    attribute with the path like /soa/ftp/file (example path). If you are writing to a remote FTP server you need to create a Connection factory for that as above.
    Please try this and let me know...
    Thanks,

  • How to disable parsing for FTP uploads?

    I would like to upload documents into iFS using FTP, but I don't want them to be parsed during upload. How could I disable parsing for FTP uploads?
    Thanks, Daniel.

    Hi, Are you using FTP inside or outside of Firewall. We are facing problems in ifs uploading when the users are outside of the firewall. This problem does not exist if we are using port 21, but since this is a well know port, we choose to use something else.
    May be you can share with us on how to configure IFS to enable ftp ( except port 21 ) outside of firewall.

  • FTP between iSeries Servers from ABAP stops after 500 rows

    Hello together,
    we wrote an abap program which should transfer a iseries DB Table from
    SAP to an other iseres DB2.
    The program writes approx. 500 rows. The table has approx. 600 rows.
    If we use a smaller table to transfer, the transfer will be ok.

    When I hit command+F, and use spotlight to search for files, I'm only given the opportunity to search for those files in three places: "This Mac", "Shared", and then the server or external HD that is mounted. However, in the past I was able to check a box for all mounted/connected servers/HDs, and then do a search in all of them at the same time. I CAN'T FIND THIS OPTION IN LEOPARD AND IT IS ANNOYING ME BIG TIME.

  • How to configure certificates for FTPS

    Hi, ALL,
    I have to send FTP files to and from outside server using like (SAP XI proxy>FTP,  FTP>SAP Xi proxy). I would like to use secure FTP (FTPS). How I can configure it in both sender and receiver FTP adapter? Does the certificate at XI  has to be signed by Trusted authority or I can do self signed? Does the outside server need to get the FTP certificate also? Can anybody provide step by step solution?
    <promising_points_removed_by_moderator>
    Thanks a lot!
    Meiying

    Hi,
      It depends if the FTP server certificates are signed for a CA installed in TrustedCA view. The TrustedCA view is a netweaver administration option included in Keystore application.
       For example, if the FTP server certificate is signed by verising, SAP contains the certificate of verising installed in TrustedCA, therefore you not have to do anything, but if the server certificate is a certificate created for you, you will have to install the CA wich you signed the certificate.
       In my case, I put files into a FTPs server that have a certificate signed by verisign and I haven't to do anything in TrustedCA view because the CA was installed.
      In FTP adapter you must to select the FTPS option to communicate to FTP server through SSL.
    Best regards

  • How do you compensate for overscanning in linux?

    The virtual screen area is larger than the actual size, and the edges of the screen are off the display. In windows I was  able to fix this using the overscan compensation in the nvidia control panel, but that option isn't there is linux.

    I have this overscan problem as well.
    My configuration: main monitor DELL 1920x1200, second monitor - Panasonic Viera S1 TV connected via HDMI. Videocard - NVidia GeForce 210. I tried both nouveau and proprietary video drivers. And with both drivers my TV has overscan problem - some parts of the screen is outside of visible TV area.
    I googled and found this helpful article http://b.wardje.eu/2012/08/nvidia-linux-overscan.html I followed it and found that for proprietary driver I have to run
    $ nvidia-settings -a CurrentMetaMode="DFP-0: 1920x1200+0+0, DFP-1: 1920x1080+1920+0 { ViewPortOut=1820x1022+50+29 }"
    This works for me and now I want to make this fix permanent. I want to put it under /etc/X11 and I guess I need to add
    Option "metamodes" "DFP-0: 1920x1200+0+0, DFP-1: 1920x1080+1920+0 { ViewPortOut=1820x1022+50+29 }"

    $ ls -R /etc/X11/

  • How to use bind_variable for connectivity between Oracle and SQLServer 2005

    The code specified below could be used as an example of how to call a remote SQLServer 2005 procedure from Oracle.
    The problem I am facing is that I am not able to use the dbms_hs_passthrough.bind_variable without exceptions.
    Could someone help me out on this?
    declare

    Hi,
    BIND_VARIABLE is useful when you have only IN variable but in your case you have IN and OUT.
    I don't know if you use the gateway for MS SQL SERVER or HSODBC/DG4ODBC but here how you can do to call a remote procedure with bind variables:
    DECLARE
    ret integer;
    inp varchar2(255);
    outp varchar2(255);
    BEGIN
    inp :='Hello World';
    outp :='';
    ret := "dbo"."in_out_proc_test"@tg4msql( inp, outp);
    dbms_output.put_line('Input value: ' ||v_ut1||' - Output value: '||v_ut2);
    END;
    The MS SQL Server procedure belongs to the user "dbo" and the database link
    being used is tg4msql.
    The following line initilaize the out variables of the procedure with an
    empty string:
    outp :=''
    I hope it helps you.

  • How to access a Network Share between two servers in same data centre

    I have two dedicated servers (both Windows 2012 Server) hosted in a data centre somewhere.   I want to share a folder on one server with the other server, but it's obviously not as straight forward as one might think.  My servers are called "Maximus"
    and "Apprentice".
    On Maximus I shared a folder by right clicking on it and choosing "Share with... / Specific People", I then typed in the name of a local user account which also exists on Apprentice with the same name and password.  (so each server has a local
    user account with the same name and password).
    So then on Apprentice, I was hoping I could access the share (while being logged in as this user with whom the folder was shared) by simply typing  "\\ipaddress\sharename" into the address bar in file explorer.  Unfortunately it comes
    back with "Windows can not access [ip address]".
    Now, I do have a website setup on the IP address for Maximus.  This is actually the reason I want to create this share.  I need the second server for load balancing and need to share IIS config as well as the website itself.  (So I will need
    two shares eventually, but for now I'm just trying to get one to work).  I don't know if the fact that the ip address is pointing to the website is causing me problems here or if it's something else.
    Are there any network gurus out there who can tell me what the issue is and how to resolve it?

    I can ping both servers in either direction, but I believe I may have found the problem.  Apparently my host is blocking port 445 which Windows wants to use to connect to the share and they will not unblock it.
    Is there a way to connect to the share through a different port?  
    To my knowledge, you cannot change the port. However, you can try disabling your security software for testing. If this fixes the problem then you need to adjust your security software configuration so that traffic on this port is not blocked or filtered.

    I have read the doco by Ivan Kovacevic amongst many others but as my clients and servers are on the same subnet, the config doesnt work.
    Can anybody point me in the right direction please. The devices are ACE 4710 running A3(2.3).
    Thanks

    Try using the following configuration:
    Note: Please make sure to configure also a udp probe to probe udp port 69, in case the application is down.
    You need to configure a management policy on the interface when using a UDP probe.
    That is because, when port 69 on the server will be unreachable, the server will send an ICMP unreachable.
    ACE will consider a udp probe as "failed" only when it sees ICMP unreachable.
    Without a management policy-map, the ICMP unreachable message will be dropped.
    Also, add an ICMP probe to the rserver because udp probe will not be enough when the physical interface will be down.
    That is because UDP is a connection-less protocol. To consider a UDP probe successfull, ACE need to see NO answer from the server in respose to the probe.
    The ACE will not see any answer from the server when the interface is down and thus, will consider the probe as "sucessful".
    With ICMP probe attached to the rserver, you also test the reachability of the server and not only the UDP port.
    Here is the configuration (of course, you can chage the names of the of the objects to the name you are using if you want) :
    access-list ALL line 10 extended permit ip any any
    probe udp TFTP
      port 69

  • How to move or copy drivers between WDS servers

    Problem: getting the same driver sets on multiple WDS servers
    At our company we have two sites and two Windows Deployment Services servers. The server at our main site had all the driver packages for the hardware we use and we wanted the other server to hold the same set of drivers. There were too much drivers
    to re-create them manually on the other server. We found no 'normal' solution to this problem, like an export or import.
    However on examining the contents of the DeploymentShare (or RemInst share) I found a folder 'Stores' containing a folder 'Drivers' which seemed to contain all drivers and a folder 'metadata' containing a database and a locked file...
    Here's what we tried on a hunch and what turned out to be working:
    Stop "Windows Deployment Services Server' service on the primary server.
    Copy folder 'DeploymentShare\Stores\Drivers' with content to another location.
    Start "Windows Deployment Services Server' service again on the primary server.
    Stop "Windows Deployment Services Server' on the target server.
    Remove or move original  'DeploymentShare\Stores\Drivers'-folder.
    Put 'Drivers'-folder from primary server in  'DeploymentShare\Stores'-folder
    Start "Windows Deployment Services Server' on the target server.
    Behold! The target server contains and services all drivers like the primary server (-:
    Use at your own risk...

    Hi Angry Technician
    I had exactly the same issue as you.  I had copied all the RemoteInstall files and folders from the original WDS server to the new server.
    The Driver Groups appeared, but not the driver files within the groups.  However when I restarted the WDS server a second time, they all appeared.  I didn't change anything in between, other than adding a Win8.1 boot image (which I highly recommend
    instead of the Win7 one!)
    I realise you've probably restarted your WDS server a bazillion times before now (the posts are quite old) but I thought this might help someone else.

  • How scale the services for 4 SharePoint 2013 servers?

    Hi,
    I have in my new farm 4 Sharepoint servers. We are more than 1K users but less than 20K users. 
    WFE1 just with IIS
    WFE2 just with IIS
    APP_Serv1 with CA and all the services except for Search Services
    App_Serv2 with just Search Services.
    Is this correct? Is this considered best practices?
    Thanks.

    Best Practices would normally suggest moving some services like Search Query, Managed Metadata, and User Profiles to the WFEs.  But there isn't just a single design that works or is the best.  Take a look at the following article.  It suggests
    which services to put on which servers.

  • How do I find the FTP info for my site?

    I created a site with Wix.com. Since then I've been exploring Dreamweaver, and the author of "Dreamweaver for Dummies" suggets that the best way to make changes to my existing site is to use Dreamweaver's FTP capabailities to download the existing pages. But Wix doesn't support FTP -- so they tell me, and simpleurl.com (where I regeistered my domain name) and which is somehow involved in the posting of my site) can't help either. Here's the Dreamweaver page that I need to fill in.
    How do I get this information?

    Yup, it's basically free, altho you can upgrade a little, as I've done. 
    And I took
    a careful look at the "source" for the pages I've created. That code will 
    show
    nothing of what I've written -- text-wise. It's all stored on the Wix 
    servers
    and accessed with various scripts. You can re-locate your Wix-created site
    after 60 days -- not before. So the suggestion I got from the "...Dummies"
    book doesn't apply here.
    Nonetheless, I'm going to continue to learn how to use Dreamweaver. Maybe
    after my 60 days are up I'll wanna move it. Don't know.

  • How to prevent iTunes for Windows from "Updating iTunes Library"? (Library is on a NAS and managed by iTunes for Mac. Now getting update wars between Mac and Windows versions of the player.

    How to prevent iTunes for Windows from "Updating iTunes Library"?
    My library is on a NAS and managed by iTunes on a Mac. I can connect from wife's Windows laptop using iTunes for Windows but every time I do, it Updates iTunes Library. Next time I log in from my Mac it Updates iTunes Library in return. It appears I'm experiencing "Update Wars" between the Mac and Windows versions of iTunes. I would like to allow my wife to stream iTunes songs to her new laptop but I don't want any updates from this source... prefer to manage the library from my Mac and not allow Windows to do any thing other than listen to existing playlists.
    Thanks for any help/suggestions.

    Connect the PC to the library on the NAS. Wait while "updated".
    Under Edit > Preferences > Advanced make sure the media folder is correctly pointed at the media folder on the NAS. If not correct, close iTunes, wait a few moments, then open iTunes again.
