View Full Version : [ubuntu] Slow internet access on 10.04 server

April 1st, 2012, 05:12 PM
I need suggestions on how to determine what is going on with my 10.04 server that I recently migrated to a different computer.

The problem is that several hours after a re-boot, internet access slows to a crawl so that updates fail and BOINC cannot receive and send tasks.

Other computers using the same router and DSL modem operate normally.

After a re-boot, everything seems fine for a time.

Dell Optiflex 745, 1gb memory, three 500 gb drives, Intel NS4000 NAS. The NAS is connected directly to the Dell on eth1. All other network is on eth0.


Ubuntu 10.04 Server, Raid 1, usual server programs, BOINC, APCUPSD, Backuppc

TOP does not show any significant or unusual activity. File sharing seems unaffected.

when you experience slowness please check what is accessing network using netstat command. Also there is another nice utility called iptraf, which allows you to monitor network activity. Those are the first steps to troubleshooting network connectivity assuming that physical layer is ok.
