Re: App downloaded from Apple App Store doesn't seem to work anymore

8 weeks ago, by Andrew in WiFi Guard Forum

Thank you for confirming the issue, we will investigate this further. Unfortunately, it is hard to estimate the time frame and the outcome, as Apple can be quite slow and unhelpful in resolving such matters. So, if you need WiFi Guard urgently, please let us know and we'll issue a temporary licence key for the DMG version for you.

Re: VLAN info Alactel 6400

2 months ago, by Andrew in Switch Port Mapper Forum

I guess the switch either doesn't provide VLAN information in its SNMP tables, or it does so in a way the Port Mapper doesn't understand (we support two locations: vmMembershipEntry and dot1qVlanCurrentEntry). If you could run the snmpwalk tool against your switch, open a support ticket and attach the snmpwalk's output, we may be able to see what happens there and advise further. We have al

Re: Enhancing multi-clause filters

2 months ago, by Andrew in Network Scanner Forum

That's a known issue with the filters. Basically when filters were first introduced, they were single-clause and so was the mechanism that manages them. Later on, the filters were expanded to multi-clause, but the managing mechanism essentially only works with single-clause filters. Thanks for drawing our attention to this, we will probably redesign the filtering system to allow editing the fi

Re: Feature request: Quick filter for Options

Great idea, we have added a search box under Options - Applications, Virtual Columns, Nmap Integration and all of the Remote [...] tools. It's more tricky with the visible columns due to its implementation though, so that's left for later. You can download the latest preliminary builds here.

Aaron, thanks for the suggestion. Just to confirm, are you referring to the below dialog? If so, perhaps it's better to add a quick filter input, so any desired entry can be instantly located?

Re: Corrupt image

2 months ago, by Andrew in RAM Disk Forum

When creating an image file, the default cluster size is calculated and used per Microsoft's recommendations. It's not related to corruption in any way. If a different cluster size is required, you could simply format the disk with the Windows built-in function or the format command and specify the desired size. There are two ways of doing that: If the image file is not being used in a RAM d

Re: How to release locked memory

2 months ago, by Andrew in RAM Disk Forum

Unmounting a RAM Disk is supposed to release all allocated memory. If it does not, something went wrong in that process. My advice would be to let unmount go as long as it needs (even if it takes up to a minute). If you terminate the application during the operation, memory leaks are possible, in which case the only solution would be a reboot. If you have a reproducible case, i.e. this happ

Back in 2014 we contacted the authors of CCleaner and they advised the following: Quote Thank you for contacting us.

Re: Corrupt image

2 months ago, by Andrew in RAM Disk Forum

Occasionally image files can get damaged. We have been unable to determine the exact cause as it seems to be random, though the usual suspects are antivirus/security products and system cleaners (like CCleaner - it's a known combination that potentially causes the corruption). To recover data you can try a third-party disk mount utility that supports entering an offset, like OSFMount, in which

Re: Options for unforeseen RAM disk capacity overflow

2 months ago, by Andrew in RAM Disk Forum

Well, if you are specifically after backing some of a RAM Disk's space with a hard drive, we don't implement it for two reasons: It's quite difficult to implement from a technical perspective; and It's already part of the OS and it's called paging, or "page-filing". There is simply no point in duplicating that mechanism. Let's take a look at the example with your PC: You have 3

Re: Options for unforeseen RAM disk capacity overflow

2 months ago, by Andrew in RAM Disk Forum

Unfortunately there isn't a way to dynamically manage RAM space with our product. Some other products feature dynamic memory allocation, for example, ImDisk. When the corresponding option is used, memory is allocated in blocks as files are written to the disk. The downside to that approach is it's slower and may result in disk write errors if no free space is available.

Re: Update 1903 Windows 10

That would be because Microsoft has changed how one of Windows kernel functions operate; it happened earlier, in update 1809. This issue is described in this article and the solution is to update to the latest RAM Disk version.

Re: Slow boot and shutdown times

2 months ago, by Andrew in RAM Disk Forum

That is way too long for a regular RAM disk. However, if you are using an image file of such a large size, that sounds about right. Let's say your SSD supports a sustained read rate of 300 MB/s. Then 192 x 1024 MB / 300 = 655 seconds, or nearly 11 minutes just to read the image file. After that some more time is spent during the memory allocation and initialisation. It is possible to create

Re: How to scan public IPs, VPNs, proxy and rogue gateways in the LAN

2 months ago, by Andrew in WiFi Guard Forum

From your questions, it is not very clear what you mean. A LAN range is usually one of these: 10.x.x.x, 172.16.x.x or 192.168.x.x. These IP addresses are private and not routable, so there are no public IP addresses in a LAN range. Scanning for open VPN services would require you to probe some TCP/UDP ports, which are specific to every VPN type. This can be done with a different application of

If there is activity when the filter is off, there are two possibilities: The filter is not correct or it doesn't match your device's traffic. If you could provide more details on how you defined the filter and what protocol your device uses, I may be able to tell more; or With NIC A and NIC B both plugged into the router, the device's traffic may never reach the emulator.

Re: Monitoring Microsoft updates traffic

3 months ago, by Andrew in NetWorx Forum

I know, we did have plans to implement NetWorx as a service, but we eventually decided not to do it. Doing so would essentially mean a complete rewrite of the product since it's too tied to being a regular app. At the same time, there are no obvious benefits other than monitoring usage when no one is logged in. As you suggested, DU Meter should be a viable alternative for those who really nee

Re: Filters currently installed have reached the limit

3 months ago, by Andrew in Connection Emulator Forum

By default Windows artificially limits your system to a maximum of eight filter drivers. If you already have eight and try to install a package with another, it won't work and will display the above message. You could either uninstall some applications and their filter drivers, or a simple Registry edit might do the trick. Just open regedit.exe and go to: HKLM\SYSTEM\CurrentControlSet\Contr

Re: Monitoring Microsoft updates traffic

3 months ago, by Andrew in NetWorx Forum

Such "unawareness" of Windows updates may be happening because NetWorx runs as a regular application, not as a service. This means it can miss traffic that occurs before a user logs in, for example, automatic updates downloaded by the operating system itself.

Re: Some proxy traffic is not recorded

3 months ago, by Andrew in NetWorx Forum

It's a little hard to understand what exactly you are doing with that proxy conversion, but the explanation of the outcome is simple: as computer A receives data from computer B, from the point of view of NetWorx it's a local connection whose traffic is disregarded. This could be worked around by either removing computer B IP address from the excluded ranges (the Setup button next to Ignore lo

Re: RAM Disk and RAID 0

3 months ago, by Andrew in RAM Disk Forum

A possible implementation of the "split" mode looks a little complicated. As there seems to be no way to find out how much memory can be allocated from a specific node, we wouldn't know how much to ask for to ensure the allocation succeeds. Let's say, we have a 100 GB RAM 2 CPU machine, 90 GB are free and we want a 85 GB RAM Disk. Things might proceed this way: Node A has 50 GB fr

Re: Large number of stopping threads

3 months ago, by Andrew in Network Scanner Forum

Sorry I am not sure what went wrong there, but it's best not to change any settings with Live Display on. The reason for that is many settings may unexpectedly affect its operation when an old parameter suddenly receives a new value. As a precaution, we will probably disable settings access while Live Display is active (in the same way it is disabled during scanning).

Re: RAM Disk and RAID 0

There is a setting accessible via the Advanced button that lets you choose which NUMA node to allocate memory from. It's only enabled on a multiprocessor machines though. Is this what you were asking for?
