similar to: Problems in Dead Gateway Detection / Failover - Multiple ISP Links

Hello all! I applied http://www.ssi.bg/~ja/routes-2.6.8-10.diff patch to kernel 2.6.8.1 and it works fine, or almost fine. It does the load balancing well, but when one link is dropped it continues to try it. At the end of http://www.ssi.bg/~ja/nano.txt it is said to ping gateway 1 and gateway 2, for the kernel to know if that route is working, but since my linux is connected to the links

Hi all! After that good thread "DGD patch not detecting dead gateway" I was able to set up a Load Balancing with ping based DGD (without Julian Anastasov patch). But now I''m facing a new problem and tried some options, with only partial solutions. I made a script based on http://www.mail-archive.com/lartc@mailman.ds9a.nl/msg16257.html (Thank you Manish Kathuria),

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

I have a doubt. If you use such a script monitoring the link status with ping and then reconfiguring, why do you need the DGD patch? You need to do some reconfiguration (change multipath to a single default route) anyway if you use the script, right? Also, the DGD patch uses src to lookup the routing table entry, but if you have a dynamic IP for the WAN interface (PPPoE, DHCP etc), this approach

(I know that what I''m wanting to do can be done, but for some reason I can not get it to work for the life of me. I think I have been staring at it too long and too closely.) I have two different internet connections from two cooperating ISPs. I also have a small 8 block of IPs that are globally routable that both ISPs will route to me via my world facing globally routable IPs that

Hello, This is on Centos 6 and not something I think is wrong with Centos 6 but I am looking to see if anybody else has experienced this and if there is solution. So thanks up front for indulging me. Because Linux makes routing decisions before SNAT it is causing problems when trying to use FTP with two upstream providers in a load balanced setup. Other than ftp, things seem to work OK. Below

Hello, Does CentOS 5.4 support large ( > 2 TB) external storage devices using GPT (GUID Partition Tables), while the main OS resides on smaller hard disks using MBR. In this scenario, what can be the largest possible size of an ext3 partition (and filesystem) which can be created on the storage array under CentOS 5.4 ? Thanks, Manish

Hello, On the Intel Core 2 Duo processor based systems, we have the option of installing either x86_64 or the i386 distribution. I would like to know your experiences with the x86_64 port. How does it compare with the i386 distribution in terms of stability, reliability and performance ? How significant are the performance benefits gained by using the x86_64 linux instead of i386 on the same

Has anyone created or rebuilt a Linux Software RAID having mirrored partitions on unequal sized hard disks ? There is a CentOS 5 server having two 400 GB hard disks with five mirrored partitions (software RAID 1) and one of the hard disks is dying. Since new 400 GB HDDs are not available here, we are exploring the possibility of replacing the faulty hard disk with one of a higher capacity (500 GB

Dear Sir, Please help me in building the right solution. My requirement is: 1st I want to club both ISP bandwidth to get 512kbps. 2nd, In normal condition, it should be in Load balancing. 3rd , In ISP Failover condition, traffic will automatically route to working ISP. What I have: I have installed the RHEL 3.0 with 3 Network Card. Kernel is 2.4.21-9EL I have the link from two ISP both

Hello! I read the Split access and Load balancing sections into LARTC (Chapter 4). However I have one gateway only and the LARTC says about 2 links. I need to know how to make a load balance with my links. Thanks in advance. Eriberto - Brazil

I configured multiple isp (actually only multiple gw) according http://lartc.org/howto/lartc.rpdb.multiple-links.html. Now NAT (Internet) seems to work, both external interfaces work ( I didnt configure load balancing because I dont need it). However I have problem that I can not ping from NAT to public ip of my Linux box. Problem is that I can not connect from 192.168.1.0/24 network to services

I have recently installed CentOS 6 on a system with a Realtek 8180L wireless card. The wireless card is detected properly and uses the rtl8180 driver. But it connects to our wireless network only after logging to the Desktop Environment (GNOME) and using the Network Manager Applet. In order to make the wireless card connect to the network automatically at system start up, I edited the Connection

How do I allow traceroute to reach my server? Pings work fine but traceroute stops at the last hop before my server. If I shut off the firewall it reaches it fine.

Hello, Is there any command / option available on CentOS to expire a user's password immediately ? I remember using "passwd -e" on some other distribution but the -e option does not seem to be present on CentOS 5.x. Thanks, Manish

Hi all I would like to know what happens with a dead router in a multipath configuration like the one presented http://lartc.org/howto/lartc.rpdb.multiple-links.html Do i need to monitor dead routers and reconfigure ? Guillermo

I have been successfully implementing load balancing gateways for multiple ISP links at various locations using Julian''s patches and as suggested in LARTC HowTo. At one location, one of the ISPs is providing connectivity through a PPOE DSL link which has to be dialled in everytime to connect. The gateway has been configured on a Fedora Core 3 based system and I have recompiled the

How are the updated kernels released by Red Hat / Cent OS related to the latest vanilla kernels ? Are the changes, new features and drivers, etc. available in the newer kernels also ported to the updated kernels released by Red Hat in their entirety ? For the lifetime of a distribution like RHEL 4 or RHEL 5, Red Hat would stick to the same major and minor number of the kernel and would just

I am facing problems assigning the owner and group to an ext3 filesystem being mounted from an external storage. I created a mount point /vol and changed its owner and group to alpha and beta respectively (as required). The ext3 filesystem (LV from the external storage) was then mounted on /vol using the mount command. However, after mounting the filesystem the owner and group of /vol changed
