sharepoint online – Remote Event Receiver(existing) stops working when a new remote event receiver is added

I’m not sure what’s going wrong, hoping someone to correct me here. I have an itemadding RER which works well and smooth, the problem occurs when i add one more to the tenant. The Second RER actually starts working after the deploy and the first RER(existing) actually stops responding. May i know why is this happening? Btw, i’m using different client ID and client secret for both the app.

sharepoint online – ItemAdded remote event Receiver return clientcontext Null working fine other same level webs pages library

ItemAdded remote event Receiver return clientcontext Null working fine on other same level webs pages library, i used TokenHelper class for get content on behalf of current login user, i tried to use Admin account as well if Client context null but that also not work , i tried to detach and attach again on new libraries but still null.

I tried below ways but no success:

  1. ClientContext clientContext = TokenHelper.CreateRemoteEventReceiverClientContext(properties)

working fine in other webs but not working on new Web Library under same site collection.

  1. // obtain web URL somehow – line below is fine for a list item RER, but you’ll need another approach elsewhere:
string webUrl = properties.ItemEventProperties.WebUrl;

Uri webUri = new Uri(webUrl);

string realm = TokenHelper.GetRealmFromTargetUrl(webUri); 
string accessToken = TokenHelper.GetAppOnlyAccessToken(TokenHelper.SharePointPrincipal, webUri.Authority, realm).AccessToken; 
using (var clientContext = TokenHelper.GetClientContextWithAccessToken(webUrl, accessToken))  
    // do CSOM stuff here..

this way showing item may be deleted or checkout by other user.

Please let me know if any other way to fix this issue .

drush – How can I suppress the “connection to @remote closed” message?

I’m running Drush 10 and have set up site aliases for my local and the remote Drupal site. When I run the following command for my local alias:

drush @local dd

This returns:


But when I run the same command for my remote alias:

drush @remote dd

Connection to “remote” closed

Why is the output different? Is there any chance to avoid the “connection closed” message?

Is this a remote code execution vulnerability?

I am planning to evaluate and install a publicly available software.

While reviewing the issues on github, there is an issue open which indicates possible remote code execution for Solr with screenshots.

I have no idea about security vulnerabilities and hoping this is the correct forum to ask experts.
Do you think this is a security vulnerability and one should avoid using the software until fixed?

windows – Remote Desktop Manager maximized view extends beyond the bottom of the screen – how to fix it?

I use RDCMan v2.7 build 1406.0. It annoys me profoundly that on my laptop I just cannot make it show the window right.

I have a chrome page with a Save button at the bottom:
enter image description here

The RDCMan is currently mazimized, but not full screen. Now I maximize the chrome window:
enter image description here

Now I switch RDCMan to full screen:
enter image description here

Notice the vertical scrollbar, indicating that the full screen of RDCMan occupies more space than my laptop’s screen resolution. It drives me mad that I cannot adjust it.

Here is the relevant properties window:

Screen mirroring remote proctoring – Software Recommendations Stack Exchange

I want to know how I can see the screens(entire desktop and all actions) of four users simultaneously. I don’t want to take remote access .
I want to just see all the activities of 4 users for 3 hours.
It is for the purpose of remote proctoring.
I don’t want to whitelist some applications because they can use the browser to open files but not for using the Internet. They can use a pdf readers but not for seeing previous saved files.v

Current remote proctoring systems I know about doesn’t let you switch tabs or move away from the tool. This won’t serve th purpose because they have to be tested on the ability to use office applications.
It has to be
Easy to use for teens (15 year olds)
And to be able to see all 4 screens at my end but they should not be able to see any screen except their own.
It should work on windows PC/mac.

What tools are possible to use
What is the cost
Are their any freeware..I just need it for 3 hours each day for 2 days.

How to use rmt linux command “remote magtape protocol”
