looking for some advice to monitor network usage in office
by Rudi Ahlers 25 Mar '09

25 Mar '09

Hi all, I've been asked by a college to setup a monitor to monitor a Windows network, but on internet usage. They want to have detailed usage, i.e. on a per IP / PC basis, and if possible to get stats for every protocol, and see over a period of time what goes on. My first though wat ntop, which does all of this, but it doesn't save the data in a DB, so if the server reboots the stats are reset to 0. I also can't get Cacti to give me stats per IP & per protocol (unless someone knows how todo this). I don't yet know the full network layout, but I have a feeling they're using ADSL, and have a Windows Small Business server with ISA, and possible Exchange as well. So, I'm either going to put a CentOS box between the Windows box & ADSL router, or maybe even setup a CentOS Vmware Virtual PC, force all the network to route via the VPS. Does anyone have some suggestions / experience in setting up something like this? P.S. Please don't look at the fact that there's Windows on the network. I use Linux for business purposes, not as a hobby, and we also use Mac & Windows where the situation calls for it. -- Kind Regards Rudi Ahlers

Limiting maildir sizes with Postfix?
by Xn Nooby 24 Mar '09

24 Mar '09

I have a small Squirrelmail server, using Postfix & Dovecot. I am trying to limit the amount of mail a user can get. The "mailbox_size_limit" value does not seem to be being honored. I am using the Maildir directory format. >From googling, it appears that "mailbox_size_limit" applies to a single file (mbox format?), and that it does not work with Maildirs. Is this correct? How should I limit the Mailbox size of the users? I'm not very familiar with Linux "quotas", but I think that is my only other choice.

question about top output
by Greenseid, Joseph M (IS) 24 Mar '09

24 Mar '09

hi all, below is the output of top off a machine i have, sorted by CPU utilization. my question is, how can all 8 CPUs say they're pegged at 100% user utilization, when there are just these 8 processes saying they're using 25% of a CPU each, and no other processes showing up taking any resources? i have run this test on other machines and they act as expected. i found this b/c this node was running a lot slower for some reason, and i can't figure out why. there are no error messages anywhere... top - 00:16:34 up 8 days, 2:05, 1 user, load average: 8.40, 8.31, 8.24 Tasks: 156 total, 9 running, 147 sleeping, 0 stopped, 0 zombie Cpu0 : 97.2%us, 1.4%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 1.4%si, 0.0%st Cpu1 :100.0%us, 0.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu2 :100.0%us, 0.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu3 : 98.6%us, 1.4%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu4 :100.0%us, 0.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu5 : 98.6%us, 0.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 1.4%si, 0.0%st Cpu6 :100.0%us, 0.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu7 :100.0%us, 0.0%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 16424052k total, 13900392k used, 2523660k free, 10560k buffers Swap: 499988k total, 152k used, 499836k free, 28700k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 8568 jgreen 25 0 2089m 1.7g 4184 R 23 10.5 109:06.90 xhpl 8572 jgreen 25 0 2080m 1.6g 4184 R 23 10.5 109:12.40 xhpl 8574 jgreen 25 0 2079m 1.6g 4220 R 23 10.5 109:07.43 xhpl 8575 jgreen 25 0 2063m 1.6g 4168 R 23 10.4 109:08.12 xhpl 8570 jgreen 25 0 2084m 1.6g 4188 R 23 10.5 109:07.52 xhpl 8571 jgreen 25 0 2067m 1.6g 4188 R 23 10.4 109:08.51 xhpl 8569 jgreen 25 0 2072m 1.6g 4196 R 22 10.4 109:07.77 xhpl 8573 jgreen 25 0 2062m 1.6g 4204 R 22 10.4 109:08.23 xhpl 4457 root 15 0 12056 1424 992 S 0 0.0 8:01.62 pbs_mom 1 root 15 0 10316 792 660 S 0 0.0 0:02.74 init 2 root RT -5 0 0 0 S 0 0.0 0:00.01 migration/0 3 root 34 19 0 0 0 S 0 0.0 0:00.01 ksoftirqd/0 4 root RT -5 0 0 0 S 0 0.0 0:00.02 watchdog/0 5 root RT -5 0 0 0 S 0 0.0 0:00.00 migration/1 6 root 34 19 0 0 0 S 0 0.0 0:00.00 ksoftirqd/1 thanks, --Joe
