If you’re using Linux or another non-Windows operating system, just create a shortcut with the following command, or run it from a terminal to start capturing immediately:įor more command-line shortcuts, check out Wireshark’s manual page.
The -i option specifies the interface, while the -k option tells Wireshark to start capturing immediately. Add -i # -k to the end of the shortcut, replacing # with the number of the interface you want to use. You’ll need to know the number of the network interface you want to use, based on the order Wireshark displays the interfaces.Ĭreate a copy of Wireshark’s shortcut, right-click it, go into its Properties window and change the command line arguments. You can create a special shortcut using Wirshark’s command-line arguments if you want to start capturing packets without delay. You can enable this setting by opening the preferences window from Edit -> Preferences, clicking the Name Resolution panel and clicking the “ Enable Network Name Resolution” check box. The downside is that Wireshark will have to look up each domain name, polluting the captured traffic with additional DNS requests. When you enable this option, you’ll see domain names instead of IP addresses whenever possible. UnixArena’s Snoop guide will help you to setup the snoop between two IP’s.Īssume you have collected the snoop output.How do you analysis it ? You can use snoop command it self to read the snoop logs.But its not user friendly.I would recommend you to use wireshark to analysis snoop output from your laptop/Desktop.Here we will see how to analysis snoop data using wireshark.ġ.Download wireshark and install it in your laptop.Wireshark can automatically resolve these IP address to domain names, although this feature isn’t enabled by default. Most of the network issues are intermediate and you never know when it will happen again.So you need to capture complete network activity to find the issues.In Solaris we have an inbuilt tool called snoop which will capture the real network traffic and save it in file. You never know where the problem resides on network issues since many hardwares involved like NIC,switch,cables, routers and firewalls.
Network troubleshooting is most difficult part in Unix Administration.To get resolve these network issues ,you need good support from network team.
