I've used ethereal before, so I'll give that another go. The problem I see is setting the capture and display criteria correctly to provide me with the information I need. iptraf I've not looked at but will give it a go if ethereal doesn't do what I want. Has anyone had any experience analysing the output from tcpdump directly, e.g. piping to a perl script to generate stats? If so, can anyone suggest pointers for me? (such as how to put the i/f into promiscusous mode directly, which I believe ethereal does on startup). > > Hope that helps :) > > > //Daniel > > > -----Ursprungligt meddelande----- > Från: Gary Stainburn [mailto:gary.stainburn@xxxxxxxxxxxxxx] > Skickat: den 17 december 2003 12:25 > Till: redhat-list@xxxxxxxxxx > Ämne: Network profiler > > > Hi folks, > > I've got two networks, both with onward connections, which are joined > together by a leased-line. > > This line should now be only be approx 25% utilised, but performance > accross the link has dropped significantly lately. > > Bearing in mind that I have very little network analysis experience, could > people suggest apps that will help me find the problem. > > I have a laptop running RH7.3+errata which I can plug into hubs connected > to each of the routers. -- Gary Stainburn This email does not contain private or confidential material as it may be snooped on by interested government parties for unknown and undisclosed purposes - Regulation of Investigatory Powers Act, 2000 -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
