Hi Guys, I'm 100% sure this is not a Linux issue but I want a second opinion... I have a Linux server running CentOS. It was been absolutely perfect without any errors or problems. Since Monday it has been unable to send email. It is configured to act as a smart host. All email gets forwarded to smtp.isp.net. The server is on a network behind a firewall completely nat'd. No ports

Hi Guys, I'm looking for a VPN solution that will run on CentOS. I've used PopTop with success but some clients have problems at hotels and other firewalled locations. If anyone can suggest something that works well with MS 2000/XP, doesn't require too much tweaking on the client side and is fairly resiliant to various firewall blocking, I'd be interested in hearing about it.

Hi Guys, I have a client who hopes to keep their server another 5 years making it 10 years old at that time. At this point there are no plans to add new infrastructure or a new server to the mix. Their business model is fairly static. I'd like to see them upgrade. Can anyone suggest specific reasons why running a business on 10 year old equipment is a bad thing? Specific arguments I can

Hi All, I have recently installed CentOS 6.3 with QEMU+KVM for Virtualization. I have successfully created a Windows 2003 VM with 4GB of RAM. The host server is an HP ML350 G8 with 24GB RAM and 24 cores. Details of one of the cores is shown below: processor : 23 vendor_id : GenuineIntel cpu family : 6 model : 45 model name : Intel(R) Xeon(R) CPU E5-2620 0 @

Hi All, Here's a strange one for you... I have a Linux box with a PCMCIA adapter PCI card in it. Plugged into said card is a cellular modem card. I can configure wvdial and dial the modem card perfectly. My ppp0 interface comes up and I can ping everything. I also have a network card on the motherboard. Once again, by itself the network card works correctly. That is with the modem

Hi All, I have configured Samba 3.0.23 to work with Active Directory. Based on all the tests shown here: http://us3.samba.org/samba/docs/man/Samba-Guide/unixclients.html#adssdm Things are working as expected. Most machines and users are working as expected. I do have some Windows machines on another subnet, NOT joined to the domain that are giving me grief. Going to

Hi Guys, I'm planning to take the RHCE exam soonish. If anyone here has taken the test I would be interested in getting your thoughts and experiences. Shawn

I've been playing with filesystem ACLs and wanted to integrate that with Samba to create a more transparent end user experiance. I have set up and tested a JFS partition with ACL support. I can use getfacl and setfacl with no problems to set permissions as needed. It works great. I compiled Samba with ACL support using the --with-acl configure option. Unfortunately I can't seem to

Hi All, Does anyone have any experience connecting two or more DSL/Cable modems to a Linux box to provide load balancing and failover? I've done some googling and found a few resources but very few solid experiences. I'm trying to optimize my LAN->Internet traffic for a bunch of workstations. Shawn

Hi Guys, I had a strange problem yesterday and I'm curious as to what everyone thinks. I have a client with a Red Hat Enterprise 2.1 cluster. All quality HP equipment with an MSA 500 storage array acting as the shared storage between the two nodes in the cluster. This cluster is configured for reliability and not load balancing. All work is handled by one node or the other not both.

Hi Guys, I have a server running CentOS 4.2 with a 2.6.9-22EL-smp kernel. The system contains a 2.3 TB RAID 5 array. There is a 20GB root partition with the remainder of the drive configured one large LVM volume. (/u0) I have installed Veritas Netbackup on the server and am running a few tests. Small backups and restores work just fine. When I run a larger backup (500MB) and store the
