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 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, 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.

Hello listmates, We are working on setting up two private networks linked by a public network which is fast (1 Gbit/s) but potentially insecure. Since the hosts on our two networks need to talk to each other, and do so securely, we have decided to use OpenVPN to connect them, making one gateway a server and the other a client. The connectivity part was easy to establish and worked like a charm.

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

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

What is the closest open source mail server I can replace exchange with that provides the nearest equivalent in user experience?

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

Shawn, That's a complete load of manure. I have an office full of 7960's, they work great with asterisk with the SIP images loaded. I'm about to pick up a lot of 7912's (simple one line phones, same as the 7905 but it has a built in switch). These phones have also been confirmed to work with Asterisk. I would recommend not going directly to cisco, and just find a reseller who

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

Anyone got any actual comparisons between unison and rsync specifically related to the performance of synchronization of large data sets over slow links? I have a huge tree to start replication of Friday and know that if I sync the root paths it will take ages and with the lack of any overall state of progress this won't be optimal as its likely to fail for whatever reason before it can

Ok, I''ve flogged this issue probably longer than some of you can stand by now. (remember, I''m the nut trying to use a PPro200 to support ~500 users on a 10Mb internet link :o) To appease those who think I''m nuts, I am ordering a new firewall shortly to allow for future growth. (probably a Dell PE750 with P4/2.8 and dual GE nics.) However, since I have yet to prove

Hi, I want to connect to Samba volumes on a SCO Open Server 5 over the Internet from my NT 4 workstation. My workstation is in a local domain and gets a dynamic IP address when it connects to my ISP; the Internet hostname is also dynamic and can't be predicted. I can determine my ISP's B class subnet which I have put into the smb.conf file in the 'hosts allow' entry. However,

Hello again, I have a table called line_items, with the following fields: id int item_name varchar() qty int conditions text I''ve made my LineItem model, and everything works as such (with simple text_fields).. Now I''d like for the conditions field to be a select_tag() with multiple choice possibility. I''m guessing I need some code to expand/restract the array for

Great idea Dean, "I would also suggest that maybe instead of looking to set up within the disaster zones that you consider setting up in the relocation zone (eg where people are being sent to) yes they have payphones there but having a bank of 20 grandstream phones connected a T1 is a far smarter and more effective solution and probably more meaningful." > -----Original Message-----

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
