I am taking part to the development of Scilab (www.scilab.org) on macOS and I noticed that all network requests from the software (using shell commands) fail with status = 48 (client hostname could not be found). All the commands work fine when typed directly on the terminal. I didn't find which app or service has to be added in the Security & privacy control panel. Does anybody did encounter a similar problem and found a solution ?

I've been working on a web app (front Angular, back Node/Express/Mongo) for a few months now.
I run Angular on localhost:4200 and Node on localhost:3000
Some people in our team are running the backend in a VM that runs on their computers.
So that the app works in both cases we've edited the windows hosts file to make the app point to the correct place (either the VM or the back on the local machine)
127.0.0.1 mysite
Developers using the VM changed 127.0.0.1 with their VM's IP.
Everything worked smoothly.
A few days ago, our company installed bitlocker on every PC and I believe it caused our setup to break for everyone not using the VM (which is not subject to bitlocker)
People working on localhost started receiving from the front app:
OPTIONS http://mysite:3000/auth/login 426 (Upgrade
Required)
The requests are not even hitting the Node server. Looks like they're redirected to a websocket server?
If I change the requests to target localhost:3000 the app works again but we lose the setup for people working on the VM. (thus committing code becomes annoying if we need to change the base url each time)
I could make an environment for each case but it's not clean and I'd like to know why it suddenly broke.
Try changing the port from 3000 to something else.
I just ran into this issue when a coworker tried running an express app we've been building on a Windows machine for the first time, as opposed to an EC2 instance. I've been using a Mac during development.
The issue seemed to be that 0.0.0.0:3000 was already mapped on company Windows machines. If you run netstat -an in a command prompt you may see it in use already.
hello mate this usually happens due to protocol mismatch between the PC and server.TLS 1.0 and 1.1 were permanently deprecated on June 4 2018. I suspect you’re using something that still uses and old version of TLS.
After upgrading system to Windows 10 - os 1803 we are getting below issues while working with ClearCase 8.0.1.x/9.0.1.x
Unable to checkin/checkout.
Not able to create views.
Not able to add any file to source control.
The system hangs & crashes while performing any ClearCase operation.
There is no error message, but I have attached screenshot for reference.
Please let us know if there is any issue with the Windows 10 ver(1803), any security system enabled?
Or has ClearCase provided any fix?
We have tried 9.0.1.5 and issue still persists.
This is what we got from windows event log.
The computer has rebooted from a bugcheck.
The bugcheck was:
0x000000c2 (0x0000000000000004, 0x00000000535be990, 0x000000000004efd3, 0xfffff803e01848b1)
for most of them whoever has upgraded to windows 1803 ver :( for people who are still using ver1709 it is working perfectly fine
Then I would recommand contacting IBM support: only them can update their ClearCase 9/Windows 10 compatibility matrix and confirm if MVFS is supported on a more recent (1803) Windows 10 edition.
We also facing same problem and I have raised the case with IBM. Still not yet resolved. As IBM said there are some limitations to work ClearCase with windows 10 and windows 2016.
We tried all the options except Secure boot disable. If possible please do disable secure boot option in Windows 10 and try to checkin/checkout code from CleraCase
Note : It works for Snapshot views. That means the issue related to MVFS
I'm seconding #VonC's recommendation to open a ticket with IBM. When you do that, save a step and collect a clearbug2 and a kernel memory dump to send in as soon as the case is opened. It will save the turn-around time of us asking you for it. If the installed programs list doesn't list installed security software (DLP, Privilege management sw like Avecto, other endpoint security tools), please list those separately as well.
I would also love to know who # IBM told you there are "limitations" with Win10-1803.
There are a few issues with Windows 10 "version upgrades" breaking things, but they generally don't cause system crashes. Windows 10 upgrades are actually full OS installs that then (imperfectly) migrate application settings. Anything that uses custom network providers (ClearCase is one example) will find that the network providers will be broken or partially broken. Reinstalling is usually required. Again, that has not yet been reported as a cause of a BSOD.
If the upgrade/reinstall didn't fix view creation, please post a separate question on the view creation issue. There may be things we can do to the SMB 2 caches to allow view creation to work in cases where the view storage is not on the client host.
I noticed that the screen shot you posted is a Terminal Services disconnect screenshot. Does the issue only occur over a Terminal Services client connection or does it also happen on a local connection?
I am trying to explore scapy3 on a Windows7 platform and was successful with installing the required packages. I am a beginner in this tool and I am trying a few examples from the
documentation page. I understand that scapy3 on a Windows platform is still under testing, but here in my organisation we use Python3.4 on a Windows platform and hence the need to
try this tool on a Windows platform.
To start with a very basic step, I was able to create a IP packet with some destination address, but when I execute the show() command, I get the following error.

I see that this could be some kind of encoding / decoding issue. Have anybody tried this and come across this issue?
Any help is much appreciated.
This one is too bizarre for me. In my Framework 4.0 WinForms app, FileSystemWatcher recently started giving me a null for OldName and only the parent folder for OldFullPath, not the full path of the old filename. However, some of the Windows 7 computers do this while others do not. I tried uninstalling our company anti-virus program temporarily but that didn't make any difference. I rolled back my code but it didn't make any difference.
I tried switching my application from Framework 4.0 to 4.5.2 but the problem persisted. In fact, I believe the problem is at a lower level than .NET because I wrote a test C++ program that uses ReadDirectoryChangesW() and a similar problem occurs: the problem computer never receives the FILE_ACTION_RENAMED_OLD_NAME notification, only the FILE_ACTION_RENAMED_NEW_NAME one.
I compared running processes and ended ones that are running on the problem computer but not on the non-problem one. Both computers are up to date with Windows Updates; I am hoping not to have to start uninstalling them.
I have one Windows 8 computer and the problem is not there; however, upgrading from 7 to 8 is not an option for several other deployments.
It just occurred to me to look at kernel32.dll on the respective machines, since that is where ReadDirectoryChangesW() lives. It's different.
Worky: v6.1.7601.18798
No worky: v6.1.7601.18869
Was there a recent change to the API that I need to accommodate?
Update: I found a non-working machine with v6.1.7601.18409 so that's not the problem.
In a word, Kaspersky.
To elaborate, I thought I had already tested removing KAS but maybe I didn't reboot after or something, and it's odd because it is also installed on a computer at work that does not present the problem--same version of KAS.
Note that this version is a corporate version, which installs:
Kaspersky Endpoint Security 10 for Windows
and
Kaspersky Security Center Network Agent
A central policy is pushed out to each client computer and enforced. It has control over settings, like trusted applications (a whitelist). When IT pushed out a whitelist entry for my specific application, it fixed the problem.
Note that there are several checkboxes to select for each trusted application entry. This fix only needed one of them.
Under Settings | Anti-Virus protected | Exclusions and trusted applications | Settings, there is a list that can be added to.
Do not scan opened files
X Do not monitor application activity
Do not inherit restrictions of the parent process (application)
Do not monitor child application activity
Allow interaction with application interface
Do not scan network traffic
Honourable mention must go to my co-worker, Arti Chauhan, who suggested more than once that KAS might be the problem. I thought I had fully tested when I guess I hadn't.
I am trying to launch a remote performance and diagnostics session on my Surface RT machine in Visual Studio Express 2013 by selecting Debug -> Performance and Diagnostics. However, I get the following message:
Diagnostics session failed to start.
Unable to connect to the Microsoft Visual Studio Remote Debugging Monitor named '192.168.11.43:4018 (< device name >)'. Connection request was rejected by the remote debugger. Ensure that the remote debugger is running in 'Windows Authentication' mode.
OK, fair enough, so I change the remote debugger to Windows Authentication mode, but no matter what I do I can't authenticate because my PC and tablet are on different domains (that is the way it seems anyway). The tablet is running Windows RT, of course, so it is impossible to change the domain. I have tried to start the remote debugger from the command line using the -u switch with the username and domain from my PC but that was no good either since the tablet can't authenticate it. I also tried to join the tablet's domain on my PC using the script from this answer but I don't get a successful return value (the return value is 5).
Most of the blogs I have come across say "just save yourself the trouble and switch to 'No Authentication' mode" which is what I did in the first place, but the diagnostics session refuses to run this way. What hoops do I have to jump through to get this to work?
Unfortunately I don't think you can get this to work on an RT. Our team has Pros for exactly this reason. Not being able to join a domain is the killer. :(
