According to this link:
https://learn.microsoft.com/en-us/microsoft-edge/devtools-guide/network
Edge can do a maximum of 6 simultaneous TCP connections per hostname.
In IE it was possible to change this. Can I change this for Edge and where is the registry can this be found (this is how it was done in IE)?
Try to follow steps below to disable the connection limit.
(1) Type Regedit in Run window to open registry editor.
(2) navigate to location below.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters
(3) Add new DWORD(32 bit) value.
(4) Name it as EnableConnectionRateLimiting
(5) Double click on it and set it value to 0.
Note:- User can also set the maximum desired limit for connections.

To send PDO messages, a prioritization is done, which message is of high importance, how should we understand this?
In the photo below, the point is that the priority is 181 and then for the rest, where is this set from?
CANopen isn't different from any other CAN bus. The lower the COBID, the higher the priority. 0x180 etc is just default COBID too, you can change to custom ones if you need to change priorities. In fact you have to change COBID somewhere, so that one node's TPDO COBID matches the COBID of at least one RXPDO. It's custom to change the COBID on the part that's easiest to configure, like for example a PLC, rather than changing it for a "dumb" node like some actuator.
I am trying to change Linux thread priority to real time SCHED_FIFO by pthread_setschedparam. I am getting error "no permission".
I am getting this error when the process is executed under root (sodo).
What is correct way to change Linux thread priority to real time SCHED_FIFO?
There were two reasons for the problem.
First, user limits weren't configured in the /etc/security/limits.conf.
Both hard and soft rtprio should be configured.
Here is an example:
myusername hard rtprio 65
myusername soft rtprio 65
The details about limits' configuration can be found in the file limits.conf itself.
Second, the kernel (usr/src/linux-headers-$(uname -r)/.config) is configured with parameter CONFIG_RT_GROUP_SCHED set to y.
In order to use real time priorities with CONFIG_RT_GROUP_SCHED corresponding control group (cgroup) should be created and configured.
See:
[https://www.kernel.org/doc/Documentation/scheduler/sched-rt-group.txt][1]

I have a service that uses an Docker image. About a half dozen people use it. However, occasionally containers produces big core.xxxx dump files. How do I disable it on docker images? My base image is Debian 9.
To disable core dumps set a ulimit value in /etc/security/limits.conf file and defines some shell specific restrictions.
A hard limit is something that never can be overridden, while a soft limit might only be applicable for specific users. If you would like to ensure that no process can create a core dump, you can set them both to zero. Although it may look like a boolean (0 = False, 1 = True), it actually indicates the allowed size.
soft core 0
hard core 0
The asterisk sign means it applies to all users. The second column states if we want to use a hard or soft limit, followed by the columns stating the setting and the value.
when using netty to programe,
I occur an question : "control maximum number of established connections"
Is there such a method can implements this featrue?
just like : "serverBootstrap.option( ChannelOption.SO_BACKLOG,100);"
which is used to set the maximum muber of un-accepted queue connections.
You have write such a feature by yourself. For example, you could count the number of active conections in your handler and close any additionally incoming connections if the number of active connections exceeds the limit or simply stop accepting anything.
I wish to display the TCP flags as a column in the display window. I add a new column from the Preferences but there is no field type for TCP flags (or more likely - I can't find it). How do I display the TCP flag as a column? Microsoft Network Monitor has an option for this (but can't display the time as seconds since epoch 01-01-1970 which I need). Are there any other .cap file viewers which will allow me to display both these columns?
We can add a custom column and put tcp.flags as the field name.
