ISPConfig & local administration
by Sam Drinkard 25 Mar '09

25 Mar '09

Hi list, I recently installed a package for Centos5.2 called ISPConfig. This was recommended by a buddy of mine who hosts a number of websites for various clients. Although I don't host any websites except my own, there were some features in the package that I did like the looks of. Well, today, I needed to add a new user and group, so while the machine was sitting here, I attempted to use the gui to adduser. For some reason, the process hung and never did come up. I called my buddy about that and he told me we ran through that same scenario with his machine some time back, but I had forgotten about it. The processes were shown in a ps ax as being ready to run, but again, nothing appeared on the monitor. I suspect the ispconfig somehow disables some of, if not all the built in adminstrative functions of the Centos gui, but hoped someone could prove / disprove this fact. It's rather irritating to go thru a manual user creation for me, as cli is not my strong point under Centos. I wound up using webmin to create the user and set the group for the gempak user, and then manually edited the list of allowed users in the gempak group. One thing of note, and not sure it even matters, but I got some messages like this... "Resolved address "xml:readonly:/etc/gconf/gconf.xml.mandatory" to a read-only configuration source at position 0. Then, it wrote out the same thing for position 1 and position 2, with then a warning that python-dbus not installed. I do know there apparently is a difference in python-dbus and dbus-python. Thanks for any input.. Sam

freeradius version
by Kanwar Ranbir Sandhu 25 Mar '09

25 Mar '09

Hi All, The freeradius version in CentOS 5 is ancient, so I've been considering rebuilding the Fedora 10 rpm for freeradius-2.1.3 on CentOS. That means I'll have to maintain the package, and I'm not an uber packager. Normally I wouldn't care, but in this case I do because the freeradius server is going to be critical. So, should I rebuild the F10 rpm, or should I just stick with the version in CentOS 5? Based on what I'm reading, moving to a newer release would be wise. Regards, Ranbir -- Kanwar Ranbir Sandhu Linux 2.6.27.19-170.2.35.fc10.x86_64 x86_64 GNU/Linux 11:37:20 up 19 days, 11:03, 4 users, load average: 0.17, 0.22, 0.18

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

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
