esxtop shows percentage of dropped packet on different ESXI ports. Is it possible to extract the exact number of raw packets that were lost instead? If the ratio of dropped RX packets to overall RX number is very low it may still be presented as 0% I guess. Also I need for more precise packet loss investigation on ESXI.
Is it possible to prevent docker from defining default route when using docker-compose yaml file?
If my docker-compose.yaml defines network ipam with default driver and any subnet, seams like docker (or docker compose) automatically assigns default route to the routing table of the docker that is attached to this network). Is there any way to disable it?
I need to run a docker in a pre-existing namespace, which wasn't created by docker infrastructure. Is it possible to do ? I am aware of reusing another container option but as I mentioned the pre-existing ns wasn't created by one ( so answer to this question is irrelevant). I need solution for Linux.
Sorry for newbie question for OSPF. I am in the process of learning the protocol, and there is some very basic thing I do not understand. In OSPF the routing is based on router id - which usually is one of its IP addresses. However what actually interests us, is the prefixes of the all the networks that router is directly attached to (that's the key to RIP routing tables if I am not mistake - and it really makes sense). So I am completely confused how given the destination packet IP we deduce the destination router (even before calculating the shortest path to it) without knowing network prefixes of all the networks that all routers in table are being attached to?

I would like to monitor the process' threads performance including the child threads. Is it possible with perfmon? Currently it seams to only start monitoring already open threads.
Hi we are installing x86 application as a service on windows 2008 R2 which is using OutputDebugString for debug messages.
The problem is that DebugView utility catches the debug output from the application only when application is run from console in elevated mode and not as a service.
I haven't found any KB that talks directly about this limitation of OutputDebugString in windows 2008 R2.
Anyone encountered such a problem? Is there such limitation really exists?
UPD: We are using terminal services to connect to server if that important
Suppose endpoint in public network (WAN) accesses endpoint in private network (LAN) through NAT (assume some pre-defined mapping exists so NAT knows how to route incoming request). Is it possible for NAT to change source IP address of packets coming from endpoint in WAN before transmitting the packets to the endpoint in private network? Or only destination is being changed?
I have only found "overlapping" mode, but this is very rare condition.
