Re: ramdiskc.exe parameter for cluster size

We have added a new parameter csize in the console version ramdiskc.exe, as shown below: For your information, your command line is incorrect. The /type and /mount are not supported in the console version. In fact, any options listed on the command line switches page only apply to the GUI version (ramdisk.exe, not ramdiskc.exe) and are used for manipulating disks in the GUI. Any RAM dis
Re: FritzBox 6591 router monitoring
13 days ago, by Andrew in NetWorx Forum
Unfortunately, there is nothing we can do about a specific router. Basically, in order to be monitored, a router must support SNMP or UPnP and expose the WANCommonInterfaceConfig service. If it does not support either of these, such router simply cannot be monitored. Please check our Router Monitoring chapter of the user manual and refer to your router's documentation to find out which (if any
Re: Does exFAT-formatted RAM drive allow junctions (soft links)?
17 days ago, by Andrew in RAM Disk Forum
Yes, that's the case: whatever kind of link it is, the target must exist. More specifically, it must exist at the time you are accessing it, since the system permits creating a junction pointing to nowhere. If the target folder is not there, like in your case, you will get 'Path not found' or similar when accessing the link.
Re: Different application usage reports for WiFi and LAN
18 days ago, by Andrew in NetWorx Forum
I am not sure what you mean by the separate screen shots named 'wifi' and 'lan'. The Applications usage reports are complied for each application regardless of the network interface in use. This is because applications are monitored at a higher level in the networking stack. So you can't choose between WiFi and wired connection when monitoring applications. That is why when you enable the Ign
Re: Suggestion: Port Mapper/Network Scanner hybrid app
19 days ago, by Andrew in Switch Port Mapper Forum
We have just added SNMPv3 support in MAC address resolution with SNMP. The new builds can be downloaded here. Regarding having own router settings per subnet, that's a little challenging to do in the current implementation. Instead you could either: List all your routers there, in which case the app will fetch ARP caches from all of them. There is no downside to that, except for a longer
Re: Suggestion: Port Mapper/Network Scanner hybrid app
20 days ago, by Andrew in Switch Port Mapper Forum
Yes, it's possible - please see this article: Configuring SNMP MIB query for MAC address resolution. Basically, before running a scan, Network Scanner queries ARP caches from the configured router(s). Then when scanning, it matches the IP-to-MAC lookup tables to resolve MAC addresses outside the current subnet. At the moment only SNMPv2c and SNMPv1 are supported, though we can easily add S

Thank you for the feedback. Unfortunately it's not clear why the speed testing was not working for 10 hours. Basically there are three possibilities: A testing server is down. In this case another server is attempted automatically in the next round without user intervention. Internet connection is down. Since the application can't determine whether it's the connection or the server, it will li
Re: How to backup a RAM drive image
21 days ago, by Andrew in RAM Disk Forum
To back up an image file, it has to be unmounted. The reason for that, if something is written to the image during a backup operation, the image may become inconsistent. In your case, since you have open files on your drive, it's better not to force dismount. Instead use a file-level utility for backup, e.g. a file archiver. For example, if you choose 7-Zip, you could do something like: "
Re: Will hard-linking be the best method for creating RAM drives?
21 days ago, by Andrew in RAM Disk Forum
It sort of depends on what you have in that folder. If you have thousands of small files in the folder you are hard-linking, there may be noticeable performance decrease. In this case Windows may have to look-up the link for each and every file. Otherwise the difference in performance should be negligible.
Re: Converting NTFS-formatted RAM drive into exFAT
21 days ago, by Andrew in RAM Disk Forum
No, there is no way to convert an image from one file system to another. If you want to change the file system of a RAM disk that is used with an image, you can do it this way: Create a new image file of the same size formatted as exFAT. Mount that image file as a physical drive via Image - Mount Image in the main menu. Copy everything from the RAM disk to the exFAT image mounted in step 2.
Re: Does an exFAT-formatted RAM drive allow junctions (aka soft links)?
21 days ago, by Andrew in RAM Disk Forum
In Windows, features like directory junctions, hard links and symbolic links (sometimes called soft links) only work in NTFS. They differ in behaviour as to what happens when a link is deleted or its target is moved. The topic is somewhat complex, so I'd recommend checking this article and in particular the Summary section outlining the differences. Specifically, symbolic links and director
Re: Does exFAT-formatted RAM drive allow junctions (soft links)?
22 days ago, by Andrew in RAM Disk Forum
As far as I know, symbolic links of any type are not supported in exFAT at all. They are only available in NTFS. However, redirects from an NTFS hard-drive should work, i.e. NTFS C:\somefile -> exFAT R:\somefile. Performance-wise, you can compare NTFS RAM disk and exFAT RAM disk with DiskMark.
Re: Will hard-linking be the best method for creating RAM drives?
22 days ago, by Andrew in RAM Disk Forum
There may be a slightly better performance when an application is installed directly on the RAM disk rather than when it's hard-linked. The reason for that is that a redirect from HDD/SSD to a RAM disk requires a couple more operations. Say you open C:\Program Files\Microsoft Word\Word.exe which is a hard link to R:\Microsoft Word\Word.exe. Windows will need to read the file system metadata fr

In addition to checking the filter (see above) please make sure you have the correct network interface selected in the drop-down box. A typical PC has multiple network connections, so it's likely you are starting the emulation not on the interface the traffic flows through.
Re: How to unmount a mounted image
27 days ago, by Andrew in RAM Disk Forum
It is not possible to detach an image file from a mounted RAM disk. If you want to unmount and close the image file, first you will need to unmount the RAM disk this image is linked to, then remove the image file link in the RAM disk's properties, and then you can close/move/remove/delete the image file. Regarding the list of mounted image files, it is important to know that image files can al

Well, it's up to you. If you have enough RAM you can place all your applications on a RAM disk, bearing in mind that: Data loss is possible if for some reason the RAM disk image gets corrupted, so all the applications will be gone. Some applications may break or not work properly, especially those that use their own drivers and system services. You are taking away the free RAM that those appl
Re: Placing programs on a RAM drive all at once
27 days ago, by Andrew in RAM Disk Forum
It is not very clear what you are trying to do. If you just want to move some applications to a RAM disk, perhaps a better approach would be to move their folders to the RAM Disk and then create links from their original location to the new location. You may be able to create a batch file that takes application folder name as input and does the above. This batch file can then be run for each
Re: Setting the Time-zone offset
27 days ago, by Andrew in NetWorx Forum
The Time-zone offset setting is for the situation when your ISP operates in a time zone different to that on your computer. Setting the offset makes your day to start at your midnight, not when there is midnight in the ISP's time zone. Everything in NetWorx, including reports and quotas, operates with 1-hour granularity, so it can be either 12AM or 1AM (but not 12:40).

NUMA is only applicable to multiprocessor systems, i.e. those with more than one physical CPU. The NUMA nodes are essentially couples of CPU + memory: On such systems, allocating the entire RAM disk to a single node improves the performance (interconnect and remote access are more "expensive" in terms of resources). Most consumer-grade PCs are single-processor, so the selecti

Re: Router monitoring suddenly stopped
4 weeks ago, by Andrew in NetWorx Forum
Sorry it's not clear what by mean by 'still nothing'? Is NetWorx application not running, or is it running but not showing any data from the router? It's unlikely that the router has blocked you, they don't really do that. However routers do have bugs in them, especially in their UPnP implementation when reaching 4 GB mark (2^32). In that case SNMP may be a more reliable option if your router

They are totally different products. Bandwidth Manager is designed for imposing quotas and download limits for many users in a network. It usually runs on a server and monitors LAN user activity according to predefined rules. Whereas NetMaster is designed for individual users who want to track their Internet usage and control Internet access of other applications. Overall, we have three networ

Re: Suggestion: Port status and control

It seems that the err-disabled state comes from either portAdditionalOperStatus (1.3.6.1.4.1.9.5.1.4.1.1.23) or cErrDisableIfStatusTable (1.3.6.1.4.1.9.9.548.1.3.1.1) from Cisco extensions. I will check if we can query these OIDs and display the additional information where available in the State column.
