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 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 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

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, 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

We are building an exchange cluster with two front end Outlook Web Access servers. We would like to at least have some sort of failover, and prefereably load balancing for them. The MS recommended way is to use NLB, but for various reasons that's not working with our set up. We are looking to set up a single linux server and use something like LVS to load balance/fail over the

I''m re-reading the section on dns names in the shorewall docs: "I personally recommend strongly against using DNS names in Shorewall configuration files. If you use DNS names and you are called out of bed at 2:00AM because Shorewall won''t start as a result of DNS problems then don''t say that you were not forewarned." Having been stung by this a few times

Hi, A friend of mine has 2 lines of 512kbps terminated in two Linux boxes. He now want to remove those 2 boxes and have some device which will loadbalance the two ISPs and also have a failover arrangement. But he has agreed to give me a chance to do it on Linux for my own satisfication. Is this easy to do with lartc? How do I go about it exactly? I have very less time to do it since his

Dovecot package version is 1:1.2.15-7+deb6u1. It is in Debian 6.0.10, using the Debian package. The server is in my basement at home, and is exposed to the Internet so I can fully access my mail from anywhere. I use IMAP for reading mail.
