Hi folks, I've now a new "usb-thing" attached to a CentOs 4.3 box in my room and just followed these steps to get it up and running, hope it helps. [root@sparkbox ~]# cat /etc/yum.repos.d/mgeups.repo [mgeups] name=MGE UPS SYSTEMS baseurl=http://opensource.mgeups.com/rhfc/ gpgcheck=0 # yum install mgeups-psp Now plug the ups and check that: [root@sparkbox ups]# lsusb | grep MGE Bus 003 Device 002: ID 0463:ffff MGE UPS Systems UPS I had to restart hotplug to get the following working: [root@sparkbox ~]# newhidups -a mgeups Network UPS Tools: New USB/HID UPS driver 0.23 (2.0.2-pre2) Detected an UPS: MGE UPS SYSTEMS/ELLIPSE Then, go to /etc/sysconfig/ups and: MODEL=newhidups DEVICE=mgeups OPTIONS="-a" UPSD_OPTIONS= Just verify that /etc/ups/ups.conf has something like this: [mgeups] driver = newhidups port = auto desc = "SparkBox ellipse ASR 1000 VA managed unit" And that's all if you use the standard config providen by the MGE folks, [root@sparkbox ~]# service ups start Iniciando newhidups: [ OK ] Iniciando upsd: [ OK ] Iniciando monitor UPS (master): [ OK ] Check syslog: Mar 24 11:56:13 sparkbox newhidups: Network UPS Tools: New USB/HID UPS driver 0.23 (2.0.2-pre2) Mar 24 11:56:13 sparkbox newhidups: Mar 24 11:56:13 sparkbox newhidups: Detected an UPS: MGE UPS SYSTEMS/ELLIPSE Mar 24 11:56:13 sparkbox newhidups: Mar 24 11:56:16 sparkbox newhidups[5869]: Startup successful Mar 24 11:56:16 sparkbox ups: Iniciación de newhidups succeeded Mar 24 11:56:16 sparkbox upsd[5872]: /etc/ups/upsd.conf is world readable Mar 24 11:56:16 sparkbox upsd[5872]: Connected to UPS [mgeups]: newhidups-auto Mar 24 11:56:16 sparkbox upsd: Network UPS Tools upsd 2.0.2-pre2 Mar 24 11:56:16 sparkbox upsd: Synchronizing...

Sound Blaster Live! 24bit how to get it support?
by lnthai2002＠aim.com 24 Mar '06

24 Mar '06

Hi, I used to use the onboard sound card(SIS) and it work well with centos 4 stock and unsupported kernel. I have just got a new Sound Blaster Live! 24bit and installed it on the system. The current kernel does not detect the sound card. Is there anyway i can make this card run on centos? This is a fairly new card, why the stock kernel does not have the driver module compiled from it?

[OT maybe] netcafe firewall
by Alexandru E. Ungur 24 Mar '06

24 Mar '06

Hi all, I appologise in advance if this is a little OT, but I am building a box that will serve as firewall and router for a small 'internet cafe / netcafe' and am using CentOS... So here it is: What are the best tools to be used for keeping the potential script kiddies from 'harming the Internet' :) ? I specifically want to be able to detect and prevent portscans from LAN to Internet, and any other malware activity the clients might think of. I am particularily interested in 'the CentOS way'. For example I know there is psd module in patch-o-matic for iptables to be able to do the portscan detection in firewall... but, that doesen't feel like 'CentOS way' (because I have to build a cusom kernel) unless there is some kernel (even 3rd part, unsuported/etc.) that already has this in... Also I know of the portsentry tool, but the project seems pretty much dead after Cisco bought Psyonic... and again is not on up2date's list... I intend to use Snort, though I hope that it won't share portsentry's fate and become extinct after Check Point's acquisition of Sourcefire will be completed. No FUD intended on this, optimistic views are always highly welcomed :) Luckily denyhosts has no plans of selling itself to anyone so that's one project I can safely use :) So, Open Source portscaner for CentOS... anyone... ? :) Thank you for your time and help, With respect, Alex

Webserver redundancy - help
by Wayne 24 Mar '06

24 Mar '06

Hey Guys, I have 3 webservers rented with a datacentre. Each of them provides the same webservices to different clients. So clients A,B,C would log onto webserver 1. Clients D,E,F log onto webserver 2. Clients XYZ, log onto webserver 3. Each of the webservers provide the same services using apache, php & mysql. Data is collected from an application logged to sql and the users can view / manipulate that data over the web. My problem is there is no redundancy. If webserver 1 goes down then clients A,B,C have no services. I need to add in redundancy. I can't at the moment afford a 4th server. So I need to make do with whats currently there. Were talking about 100megs of new data on each server per day. Would something like mysql replication be the best bet? Anybody have any better ideas? Correct me if Im wrong but under replication wouldn't one server be a master and all others be slaves? So if I made webserver 1 the master then all clients would have to log into that one if they want to manipulate the data and if it goes down them Im screwed on all clients? I know I need a better setup just wondering whats the best way to go about it... Thanks, Wayne

/bin/false as a login shell
by Kai Schaetzl 24 Mar '06

24 Mar '06

I see that /bin/false is not a valid shell by default on CentOS. It is f.i. on Suse. /bin/false is present, though. Is there a security reason for this? man says that nologin gives feedback that the account is not available while false just exits false. Anything against just adding /bin/false to /etc/shells?

>Jerry Geis wrote: >>/ I had trouble with the update to 4.3. />>/ />>/ How do I tell what program that is and stop it? />>/ />Personal favorite way: ># /sbin/fuser -v 22/tcp Looks like there really is no port conflict - my laptop does the same thing and the commands suggested return no program using the port on my desktop (messed up box). It works on my laptop with sshd running. Actuall sshd does RUN. however when I try to connect it is saying "connection closed". I have ran system-config-securitylevel and have ssh enabled. I have rebooted... I cannot get sshd to allow me to connect. httpd still wont start. I see no entries in messages other than httpd failed. I dont know what else to do/try. THanks for any suggestion.
