Time difference is the offset from local time to UTC (rather than the Take care in computing the sign of the time difference. Olson time zone database names and instead you must specify an absoluteĪnd this offset is the opposite of the colloquial offset: However, on Windows, the TZ environment variable does not support Using the Olson time zone database name (Time zone ID: ) On POSIX systems such as Linux, this is just a matter of Launched from a terminal after setting the appropriate TZ environment Wireshark does not match the capture system, then Wireshark must be The packets were captured, if the local timezone of the system running To show absolute timestamps in the local timezone of the system where To show these UTC timestamps, click View > Time Display Format > Libpcap, the timestamps in the capture are stored as UTC ( ). For the most common capture formats such as It's often useful to show absolute timestamps toĬorrelate to other logs. Is handed the packet from its way from the client to the NIC, before itīy default, Wireshark shows relative timestamps (seconds sinceīeginning of capture).

There is no way with a single capture to know how long it took for.For most purposes, focusing onĪ TCP stream, i.e. Following a stream means extracting the subset of a conversation,įrom the point of view of an application.An endpoint is a logical endpoint of a protocol or network layer.įor most purposes, focusing on an IP endpoint, i.e.A conversation is the set of packets between two endpoints.Wireshark supports the packet formats of most operating systems.

I've checked for duplicate IPs, checked the firmware and drivers on all of the devices but I can't spot any obvious problems.įor awhile I thought that the in-house DNS service was acting wonky but I flushed the cache and set the devices to use 8.8.8.8 and 8.8.4.4 instead and that only fixed the connectivity on a single android device that was connecting to the WAP.Wireshark is an open source program to perform analysis on capture

Hardware is Windows 2003 and 7, IOS (iPhones specifically), android (smartphones) and an Engenius WAP plus a couple of networked printers. Maybe a couple dozen in total over 15 minutes, randomly scattered throughout the capture. I've captured 15 minutes of packets with wireshark and the most exciting thing that came up was a handful of: Lately (especially within the past 72 hours) I am seeing all kinds of ethernet (wired) problems with connections breaking for 20-40 seconds then coming back by themselves, slow connections, and all kinds of general network wonkiness. I am in an environment with a couple of switches, a couple of wireless access points and Cisco firewall/router to the outside world.
