I just taught a class of ~20 students, and 1 out of 20 of them was having this same problem. He was using Chrome, and eventually we saw this thread and he tried again on another browser, but it does seem to be a server error that is limited to a particular user account. I'm happy to send along the file(s) we were trying to upload, but the other 19 students had no problem, on a range of browsers and OSs.

SNMP is used to pull the printer details from the pritner hardware to the driver thats connected to it over direct IP address (at least with HP it is), items like tray counts, stacker / staplier installed, the amount of RAM and as far as i know (Network Specialist over 20 years), these sharing systems (Saved Settings) are direct coms from the sharing server to the client PC

I don't use SNMP on my ports as I get too many Offline issues client side due to the fact it means the driver ends up sending double the traffic due to be used in the driver already under the Configuration tab and then it doubles again (effectively quadruples) from the client connection. It is possible this is where your issue comes from.

will only add rules for Samba acting as a server. It will not add any rules for Samba acting as a client. But when you try to mount a remote share, that's what you are doing: in this scenario your machine is a client, and the remote machine is a server.

The rules that allow Samba to act as a server are not sufficient to also allow Samba to act as a client, because the remote machines respond from their own port 137, but the local port on which these responses arrive is not 137, it is some random port.

This will allow UDP packets to arrive into any local port as long as they are originating from port 137 or 138 of the remote computer. The port 138 is probably not necessary, as I have only seen packets arriving from 137, but you never know.

My problem was due to /etc/samba/smb.conf. Searched for WORKGROUP and deleted the line after it which mentioned a localhost name. Make sure the WORKGROUP is the same for both config files on each machine. An all round way is to sudo apt-get purge samba (and/or remove ?) and then sudo apt-get install samba. This is how I solve the problem the first time round, after upgrading from 16.10 to 17.04 on one of my machines (16.10 was buggy for me). I have two machines now: 16.04 and 17.04.

I still couldn't search the server name. Then I thought wait, the computer name & samba name are different. So I edited hosts & hostname, changing them to the samba server's name. Careful hostname only has one word in it. The computer name no # comments.

Even with successful communication between User's source IP and Dst IP, we are seeing tcp-rst-from-client , which is raising some queries for me personally. Are both these reasons are normal , If not, then how to distinguish whether this reason is due to some communication problem.

@Jimmy20, Normally these are the session end reasons. Now depending on the type like TCP-RST-FROM-CLIENT or TCP-RST-FROM-SERVER, it tells you who is sending TCP reset and session gets terminated. It does not mean that firewall is blocking the traffic. It means session got created between client-to-server but it got terminated from any of the end (client or server) and depending on who sent the TCP reset, you will see session end result under traffic logs. And once the session is terminated, it is getting reestablish with new traffic request and thats why not seeing as such problems with the traffic flow.

Thanks for reply, What you replied is known to me. But i was searching for - '"Can we consider communication between source and dest if session end reason is TCP-RST-FROM-CLIENT or TCS-RST-FROM-SERVER , boz as i mentioned in initial post i can see TCP-RST-FROM-CLIENT for a succesful transaction even, However it shuld be '"tcp-fin" or something except TCP-RST-FROM-CLIENT. if it is reseted by client or server why it is considered as sucessfull.

TCP RST flag may be sent by either of the end (client/server) because of fatal error. So if you take example of TCP RST flag, client trying to connect server on port which is unavailable at that moment on the server.

Now in case, for a moment particular server went unavailable then RST will happen and user even don't know about this situation and initiated new request again And at that time may be that server became available and after that connection was successful. So In this case, if you compare sessions, you will find RST for first session and 2nd should be TCP-FIN. So like this, there are multiple situations where you will see such logs.

Does anyone really have a solution for this? So far, I have not seen any concrete solution. I put a device that communicates with an online server with no problem. I insert the PA FW between that line of traffic, all of a sudden, we get tcp-rst from the server or vice-versa. What causes the problem and do we solve it is what everyone is seeking as a guide or repsonse. I think most technical people understand how tcp works.

I have an old 2012 R2 DC that is running DHCP for my organization and I need to migrate the scopes to a new 2022 DC. Over the years I've simply re-created the scope since it was usually only one. However this server has over 50 individual scopes so I obviously don't want to re-create all of them. I have done some googling and have tried a few things but so far nothing has worked.


I have tried using the backup/restore function from the DHCP console but it fails with the message "The database was not restored correctly. No changes were made. For more information, please see Event Viewer on the specified server." When I check the event log I see EventID 1019 that says "The DHCP service failed to restore the DHCP registry configuration. The following error occurred:

Access is denied."


Some of the instructions I have found say to delete the DHCP database on the new server before attempting a restore. I have some test scopes in there that I would prefer to keep. Is it possible to merge the restore with the existing database or do I need to perform a complete overwrite?


I have also looked into using Powershell which would probably be simpler to use for this but again they all indicate I need to overwrite the existing database on the new server with the restore. Is this the only option?


I'm hoping someone here can give me some clarification on this.



If you specify the ScopeOverWrite parameter and the scope being imported exists on the destination server, the scope on the target DHCP server service is overwritten. If this parameter is not specified and the scope being imported exists on the destination DHCP server service, a warning message is displayed and the import proceeds to process the next scope being imported.

Server Actions are asynchronous functions that are executed on the server. They can be used in Server and Client Components to handle form submissions and data mutations in Next.js applications.

A Server Action can be defined with the React "use server" directive. You can place the directive at the top of an async function to mark the function as a Server Action, or at the top of a separate file to mark all exports of that file as Server Actions.

To call a Server Action in a Client Component, create a new file and add the "use server" directive at the top of it. All functions within the file will be marked as Server Actions that can be reused in both Client and Server Components:

This is useful in cases where you want to call multiple server actions within a form. For example, you can create a specific element for saving a post draft in addition to publishing it. See the React docs for more information.

To improve the user experience, we recommend using other React APIs like useOptimistic and useTransition to update the UI before the Server Action finishes executing on the server, or to show a pending state.

You can use the React useEffect hook to invoke a Server Action when the component mounts or a dependency changes. This is useful for mutations that depend on global events or need to be triggered automatically. For example, onKeyDown for app shortcuts, an intersection observer hook for infinite scrolling, or when the component mounts to update a view count:

However, for this to happen, the captured variables are sent to the client and back to the server when the action is invoked. To prevent sensitive data from being exposed to the client, Next.js automatically encrypts the closed-over variables. A new private key is generated for each action every time a Next.js application is built. This means actions can only be invoked for a specific build.

Good to know: We don't recommend relying on encryption alone to prevent sensitive values from being exposed on the client. Instead, you should use the React taint APIs to proactively prevent specific data from being sent to the client.

To mitigate this, you can overwrite the encryption key using the process.env.NEXT_SERVER_ACTIONS_ENCRYPTION_KEY environment variable. Specifying this variable ensures that your encryption keys are persistent across builds, and all server instances use the same key.

For large applications that use reverse proxies or multi-layered backend architectures (where the server API differs from the production domain), it's recommended to use the configuration option serverActions.allowedOrigins option to specify a list of safe origins. The option accepts an array of strings.

I am running Windows 11 and have a Microsoft 365 subscription. I am a member of the Office Insider as well . Microsoft Outlook for Microsoft 365 MSO (version 2109, Build 16.0.14430.20224) 64 bit is giving me an issue. I have always used the most up to date Outlook Desktop App and have created hundreds of rules on there that run on a daily. During the transition to Windows 11, I think there was an issue with the Rules. I keep getting the same error message at startup of Outlook, "There was an error reading the rules from the server. The format of the server rules was not recognized." When I go to Manage Rules & Alerts on the desktop app, there are no rules in the list. However, if I log on to the Online Web App on my browser, all my rules are currently there. The rules seem to be working as of now but I fear something may happen to them. Under app in the settings of Windows, I selected Microsoft 365 - en-us and hit the Quick Repair option to try and resolve the issue with no success. I also confirmed and I do have the latest Office 365 update. I have looked the issue up online and most people say to delete and add a rule and it will sort itself out and that has not helped. This is very annoying and every time I open Outlook I get the same error message about 10-15 times and I have to X out of it every time. Does anyone know of a solution? My end goal is to not have that error message come out on the desktop app and for the Rules to show up on my desktop app like they are on my online web application. ff782bc1db
