Users for a diskless system with NFSv4

I'm trying to set up the root filesystem for a diskless Arch client on an NFSv4 share. It just dawned on me that, based on my understanding of user mapping for NFSv4 (user mapping by name rather than numeric UID), any user that owns files on the client system will need to exist or be explicitly mapped to a user on the file server, otherwise the files will end up owned by nobody.
Is that accurate? How do other people handle diskless sytems with NFSv4? I'd rather not have to set up NIS or Kerberos, if it can be avoided. The file server in my case is a FreeBSD box so the systemd and daemon users won't necessarily match up.
Does anyone have experience with this?

ambsace wrote:In real life, though, my diskless system has (or will have) a root filesystem, on a disk array in a different system.
So, what I'm missing here? A diskless system will boot from network and maps the root filesystem via nfs. This is comparable to a local installation, where is a second system involved here?
Ok, got it. You mean the user mappings between the root filesystem of the diskless system and the fileserver itself. Because you talked from a "client", I thought you are talking about the mapping from a "client" machine to the nfs structure. Sorry for the noise.
Edit: Typos and more...

HT201240 This process does not appear to work for me. I'm running 10.8.3. I created a new user for a guest staying with me. They have gone now and I am attempting to either change the password or delete the user. It won't allow me to choose the user I

This process does not appear to work for me. I'm running 10.8.3. I created a new user for a guest staying with me. They have gone now and I am attempting to either change the password or delete the user. It won't allow me to choose the user I created. I am logged in as myself and it states that I am an "Admin". The user I'm attempting to change is listed as a "standard" user and there is a white checkmark inside an orange circular background on the user pic in the list of users.
Can someone help me? I am having a hard time believing that OSx will allow me to create users and allow them use of my computer and it's drives, yet it will not allow me to change the password so I can monitor what they might have been doing while logged on? What if this were my child? This guest left under sketchy circumstances, and I'd really like to be able to ensure they were not using my computer to do illegal things or to have illegal communications.
Any help would be appreciated. (It's odd that it was so simple to "create" a user and set a password for them.......but it's complicated or a little known process to reverse.
Thanks.

Here are two screen shots to show you what I am seeing. The first screen shot shows it allowing me to select (highlighted in blue) my admin user (which is what I am locced in as). The second screen shot shows it allowing me to select the "Guest" user (highlighted in blue). However when I click on the user "Orion" nothing happens. It will not change to highlight that user.

Create User for Target (Terminal Adapter) with private key authentication through web service

Hi
I have a question about Terminal adapter.
My current aim is to create process "Execute script through ssh on remote Linux system" with input parameters ( login, path to private key, path to script)
It was very helpful to find this discussion https://supportforums.cisco.com/message/3543289#3543289 .
Is there a way to create Public-key Authenticated Admin Runtime User with private key for authentication by using NB webservice ?

I will second Shaun's comment...
Unfortunately, it looks like this is not possible in 2.3.X. (That is you can create the user but the fields you need to use to configure that user properly do not appear to be exposed to the Northbound Web Service).
It looks like something that will be fixed in a future release of Process Orchestrator.

How to setup EWA for non-ABAP system with SM 4.0 ?

Hi, we are running SM 4.0 with the support-stack 06. I have set-up a solution for monitoring which includes a NW04 WebAS 6.40 Java only system. Has anyone set-up EWA reports for this type of non_ABAP system who can advise of the steps necessary for this ?
It seems like you need to define RFC destinations for where the monitored system data should be collected from , but there doesn't appear to be anywhere to do this for non-ABAP systems ?
I have looked at Note 738676 - Service Data Download for Non-ABAP Components but it hasn't helped and it seems to be SDCC specific, rather than SDCCN.
Thanks.

Hi Andrew,
we are just developing it, at the moment you have the following option, your java system has to send by ccms agends its data to an ABAP 640 system or higher, there you can see its alerts in ccms, then you have to make both system available in SMSY. Then important you have to assign the java system as a system component, then we collect also the java data and shows them in the EWA of the ABAP system. There for go to the main instance tab and set a java main instance to relevant and assign your java system.
This is the old, available standard solution. At the moment we develop it also for java stand alone.
I think it will be available with the new ST-SER in autumn

How to delete users in the child systems with CUA?

Hi All,
We have:
1. My SAP ERP 2005 (ECC 6.0)+ Windows 64bit + Oracle 10
2. EP 7.0 + Windows 64bit + Oracle 10
3. BI 7.0 + Windows 64bit + Oracle 10
4. Solution Manager 4.0 (CUA)
We managed all our QA and DEV users in ECC, EP using CUA from the Solution Manager server (Productive servers and all the BI 7.0 System Landscape aren't in the CUA).
My problem is when i want to delete a user. Sometimes if you delete a user in the solution manager (where the CUA is defined) the user still exists in the Child Systems. In fact you can see it with the SU01 only in the child system. I guess the idea is that if you delete the user in the CUA them the user is delete in the child system.
I found this information in the SAP Help:
As well as the authorizations already mentioned, you also need another authorization in the central system for object S_USER_SYS. You can only assign new systems to a new user with this authorization. ( No Problem with this )
When a user is deleted in the central system, the system entry for the user is retained until the deletion is confirmed. If an error occurs, you can repeat the deletion by canceling the system (in the child system).
What does mean: deletion is confirmed?
Best Regards,
Erick Ilarraza

Hi, thanks a lot for your reply.
We used the SAP Transaction SCUG to solve CUA Problem.
It is something about the refresh of the user in the Parent / Child systems, you need to Re-Refresh users and delete it again.

Prompt user for input when rdp with same user as logged in

What I am trying to achieve: user dragos is logged in on a domain computer. When I connect with rdp with the username dragos on the computer I want user dragos to be asked if he allows the connection or not not to be taken over.
When you connect as different user it is being asked, but not when connecting as same user as logged in.
Searching for solutions I found this: Administrative Templates\Windows components\Remote desktop services\Remote desktop session host\Connections\Set rules for remote control of Remote Desktop Services user sessions and give it Full control with user
permission.
But it does not work as I was expecting.
Is there a solution for the logged in user to be promped if connecting with the same user name ?
Thank you

Hi,
user dragos is logged in on a domain computer. When I connect with rdp with the username dragos on the computer I want user dragos to be asked if he allows the connection or not not to be taken over.
As far as I know, there is no built-in method to achieve this.
You may try to search whether there any third-party tools which can achieve this, or write a script.
If you need assistance with scripting, here are some scripting forum links below for you:

Products that necessary for construction a system with offline cli

Hi all. Please help me.
I would like to construct the system, where there is one central DB and many clients, but clients should work with there's local DB when connection is fault.
So I have understood that I should by Oracle Client(s) and Oracle Server. And then should I by Oracle lite and Oracle Standard Edition too?
Thanks a lot

A Standby database system consists of one Primary database (which is used to do work on) and at least one Standby database, which is, typically, a Physical Standby. That means that it can't be used for "normal" work, but, instead, is set-up to receive all of the changes made to the Primary database, on an ongoing basis. Thus, if the Primary database is destroyed, then the Standby is converted to become a new Primary database, allowing work to continue, with (depending on how it's set-up), zero/mimimal data loss.
It's a big topic, and you really must read the Oracle documentation. Or get someone to come in and explain it all to you. That's the only way you'll be able to decide what you actually require... and possibly save you money.

New user for ipod 4th gen with click wheel

I hope i'm posting this in the right place. My daughter purchased an ipod 4th generation with click wheel offebay, didn't come with software. So I downloaded I tunes off the net. was told the driver for ipod was included in Itunes? I'm computer illeterate, I appologize for this. I'm not sure, but I think I have 2.0 ports on my laptop, it's about l l/2 years old. windows xp I plugged the ipod into my computer after downloading itunes, and the computer doesn't recognize the ipod, a box comes up and says this.
" one of usb drivers attached to this computer has malfunctioned and windows doens't recognize it.
I tunes does come up but there is no ipod recognized on itunes it's suppose to come up under devices on the left side of itunes, but nothing comes up. I can import music to my laptop using itunes, cannot put the music onto my ipod.
I'm completely at a loss here, and really don't know what to do.
The serialnumber on my ipod is 2CD44617K8 which I got off the back of the ipod.
I also typed this number in the apple web site and it doesn't recognize the number either.
I have contacted the ebayer this was bought from and he hasn't returned any emails and doesn't act like he wants to help in any kind of way. I'd like to make sure it's opperator error and not something wrong with the ipod.
thanks in advance
kathy

This is the wrong forum for your question, this area is for people with the latest iPod nano.
You need to post in the correct forum and you will probably get more help.
Are you sure you have bought a 'real' iPod, could it be a fake?
Does the eBay seller have good positive feedback, it could be that the iPod is actually broken. Does the iPod turn on, can you use the menus, etc. You should be able to operate the iPod without any music.

You need Oracle Enterprise DB and Oracle Mobile Server. Mobile Server will handle the deployment and distribution of the Oracle Lite clients.

RFC User for satellite systems

Hello Gurus,
I just wanted to ask about one issue. We are a SAP partner and using Solution Manager in VARs scenario. There are many systems of our customers connected to our Solution Manager..
Now I want to ask about RFC user(s). As I see, in our Solution Manager there are many users(communications type C) with Synthax SOLMAN<system id> or something like that. It means basically, that we have for every particular customerS system one SOLMAN user for RFC(cust_scout) in our Solution Manager. My question is if we can replace all of these users with only one RFC user for all the systems and customers?
Many thanks in advance for your help

Hi Miloslav,
Technically, it will work that you define one common RFC user in your SolMan for communication (RFC BACK destination) from all connected managed systems.
BUT, I would never recommend it.
Once a managed system cause issues in your SolMan, you are not able (or at least it's much more difficult) to identify the managed system. Same happens, if a invalid password in the BACK destination leads to a locked user.
My recommendation: Spend the extra effort in creating a user per managed system. Operation will be much easier later.

Multiple SAP Systems with one Unique ID

Hi,
SAP recommend to have <sidadm> and <sapserviceSID> user account for each system.
Currently we create domain users for each SAP System. We are installing many test servers and trying to see if I can avoid creating domain user account for each system and use only one account to administer all test sap systems.
Just wanted to know if there is any way to have one domain SIDADM user id and one domain SAPService user account to run multiple test SAP systems?
Thanks,

Hi,
Multiple test system you have different SID. so you must use different SAPserviceSID user. But you can use one SIDADM user with the proper permission with other test systems.
I have used in OS400 environment with single SIDADM user id.
please check with users with permission sap notes or document.
But SAP not recommanded this.
Thanks and Regards,
Jibin.

SAP PI Modeling: Two Business systems with party

I am triing to create SAP BPVT Interaction model that describe connection of 2 process components. Each of that components must be business systems with party. As I understand process component must be Process component at business partner for assigning business system with party.
If I create SAP BPVT Interaction model with two Process component at business partner, I get they connection in type of "Other Interaction". When I try create new assigment, I get error "Unable to assign the model to this connection type due to the method or profile in use".
How can I create correct connection?

Hi Eugenia,
Please see note 1084315 which descriibes the the multiple backend scenario.
This should be relevant here.

Multi users for my iPad

I want to create different users for a family iPad with different restrictions for children. How do I create homepage with password entry for adult and children.

The iPad is designed as a single user device. There is no way to create different user accounts. If all users access their email through a web interface, they can log out when done.

SSO for application systems with local users?

Hi all, I'm new to Oracle Identity Management. My company is going to implement SSO for inhouse applications. However, some applications have their own local users (e.g. admin, guest, etc.) who have to login to the application system through the same interface. We put all organization users in an Oracle enterprise Directory server, which is the authentication backend of the Access Manager. After implementing webgate, such local users can't get authenticated. I'd like to know if it's possible to configure particular users/applications to bypass SSO and use local authentication? Thanks.

Possible solution is to create a new entry point for local users. Create two proxies one for actual user entry and another for local user. You can restrict n/w access to proxy with local login so that only few hosts based on your requirement who needs to access system with local accounts. This way you will have two web sites for single application.
