Re: Scanning over 20 SNMP OIDs at once

4 months ago, by Andrew in Network Scanner Forum

Yes, you can scan any number of OIDs. There is a default limitation of 10 SNMP columns, but you can increase that by launching the app with /maxcols:N. For example the following will allow up to 30 SNMP columns: netscan.exe /maxcols:30

Re: Feature Request: Specify DNS server per address range

4 months ago, by Andrew in Network Scanner Forum

Normally the Network Scanner app does not interact with DNS servers directly. Instead it uses system calls like getnameinfo() to resolve a name to IP address and vice versa, which uses system mechanisms and default DNS servers. However it sounds like an interesting idea to be able to query custom DNS servers. Do you have many DNS servers there? I am thinking of just adding a customisable list

Re: Best CPU for the job: E5 or E7 or I8/9 series

Well, the faster the better, but generally most CPUs should be able to handle a few hundred rules with up to 400-500 Mbps.

Re: Best CPU for the job: E5 or E7 or I8/9 series

Internally Bandwidth Manager uses one thread per network interface, so the quantity of cores may not have much effect. The more GHz the better though. There are usually other ways of improving performance, like reducing the number of rules in favour of a smaller ruleset with per-client tracking. If you just outline your setup and perhaps post a screen shot of the main display with rules, I

Re: Shared status lost on RAM disk after reboot

4 months ago, by Andrew in RAM Disk Forum

It is probably indeed the case: a RAM disk is ready after the Server service has started. This is more likely to happen for large RAM disks as they take more time to initialise. The easiest workaround is to change the Server's service to start delayed as shown below. Delayed start usually takes place within 2-3 minutes after boot, by which time the RAM disk should be ready.

Re: Feature requests: comma-separated port list, and quick telnet/ssh to a switch

4 months ago, by Andrew in Switch Port Mapper Forum

Hi Scott, thank you for the feedback! Regarding comma-separated values It is indeed a good point that sometimes one may need the values comma-separated rather than new-line separated. We have just added a way to do that. Download the new builds (installer, portable), hold Shift when copying column values. With Shift down, the result will be comma-separated. With Shift up, the result wil

Re: How to change the taskbar graph font size

4 months ago, by Andrew in NetWorx Forum

There is a couple of settings that help you change the graph appearance. The settings are located in so-called Hidden Options, and can be easily accessed by pressing Ctrl + O in the regular settings dialog. In particular you may want to set Overlay desk band numbers to FALSE and increase the Rates font size. Please note that you could also resize the graph. First, right-click the taskbar an

I am not sure there is a reliable way because the extender hides those devices behind itself. The way I can think of is to ask those devices directly. If those are Windows-based machines and file sharing is enabled there, the following setting should do the trick: Activate the NetBIOS query option Move it to the top of the list As a result, before sending an ARP query that gets intercept

Re: Error C000009A

5 months ago, by Andrew in RAM Disk Forum

Again it's an odd error that indicates a resource shortage (not necessarily memory). Perhaps try with a different file system and the Hard Disk Emulation option on and off? If the above doesn't help, try using a logon-time disk instead of boot-time one or vice versa. If still no luck, what about two RAM disks of 4000 MB each?

Please try with the latest version (4.0.7). In particular we've improved memory allocation strategy in v4.0.5. Does a reboot help?

Re: NT error code C0000184 at loading

5 months ago, by Andrew in RAM Disk Forum

Granted it works with the HDD emulation off, there might be an uninitialised disk device or similar. Could you please launch (Win + R) diskmgmt.msc and post here a screen shot showing all configured disks? This may shed some light on your situation. But even if we can't tell why it happens, you will likely not see any difference with the HDD emulation off. I set this option off on my person

Re: NT error code C0000184 at loading

5 months ago, by Andrew in RAM Disk Forum

The error 0xC0000184 (STATUS_INVALID_DEVICE_STATE) generally suggests a requested resource wasn't in the expected state, e.g. not fully initialised. It's hard to tell what may be causing it since, as you say, it was working fine before; my best guess would be a system change or a third-party program installed. Just to confirm - that's a regular RAM disk without an image file? If so, please

Re: How to get monitor model and serial number via WMI query or class

You could use the following queries in the root\WMI namespace: SELECT UserFriendlyName FROM WmiMonitorID SELECT SerialNumberID FROM WmiMonitorID However those are byte arrays and will be displayed as . For human-readable format use the following VB script under Options - Remote Scripting. It will extract the byte arrays for model name and serial number and convert them to ASCII strings:

Re: How display WiFi traffic graph on Debian

5 months ago, by Andrew in NetWorx Forum

The graphs should work in the same way for wired and wireless connections. The Linux version of NetWorx supports one graph per connection, meaning you could have two graphs displayed: one for WiFi and one for Ethernet. If you share some screen shots, I may be able to advise with more specifics.

Re: How to display Windows version

I guess something like this should work.

We decided to publish a new build of 7.1.5 instead of releasing 7.1.6 to fix this Access Violation error, which also includes all prior changes initially planned for 7.1.6. Simply download the newest 7.1.5 files from the Network Scanner page: it now includes all the latest fixes and updates, including HTTPS for Remote XML.

Re: Error C000009A

5 months ago, by Andrew in RAM Disk Forum

As explained above, error C000009A means insufficient system resources, which typically indicates an out-of-memory condition. It is not necessarily low memory; for example, a similar error would occur if there was no continuous suitable block of RAM due to memory fragmentation. Please make sure you are using the latest version of the RAM Disk. I also recommend to increase the size of pagefile

Re: Ctrl+Click-drag selection bug: one item is dropped

5 months ago, by Andrew in Network Scanner Forum

Indeed this looks like a bug, I was able to reproduce this behaviour. The problem though is that it's somewhere deep down in the tree control's code, so fixing it is rather challenging. I will let the tree control's developers know, but granted it's open source they may be reluctant to spend time on this. As a workaround you can simply click the de-selected item again and it will be included i

Re: Quotas and penalties

5 months ago, by Andrew in Bandwidth Manager Forum

How long has it been in the Unlimited state before 07:43? Say, if the user has used 2 GB starting at 6:00, it sounds about right as the quota is rolling and 2 GB were used in 1 hour and 43 minutes. Then at 8:00 it's a new hour, so a new quota allowance start to be used. There is no way to make it work exactly as you describe, i.e. one hour of usage followed by one hour of reduced speed, I'm af

Re: How to change database location

5 months ago, by Andrew in NetWorx Forum

Yes, it's possible to change the database location. There are two ways to do so: Quit running NetWorx and launch it again as administrator. Then go to the Hidden Settings and enter the new path under Database location. Alternatively, use a symbolic link to redirect the folder to another location. This method can be used for any program to redirect a folder to a different location. Quit Net

Re: Speed meter is running, but the graph shows no traffic

5 months ago, by Andrew in NetWorx Forum

If you have the Ignore local traffic within in the LAN option ticked, that's the expected behaviour. The network driver ignores any usage initiated by NetWorx itself. It can make the total figures less accurate, but unfortunately it's the decision of the driver's developers (we use a third-party driver). If this is your case, just wait a few minutes for the test to finish. If you are using ver

Re: How to exclude Local Traffic, but not Traffic to VPN

5 months ago, by Andrew in NetWorx Forum

Hmm, that's quite strange as theoretically removing 10.x.x.x from the ignored IP address list should have worked. It may have something to do with how the VPN software tunnels traffic. I'd recommend to try using an alternative network driver as follows: Download and install WinPCap. Restart NetWorx and untick Ignore local traffic within the LAN.
