We have a simple configuration so we could get by with this -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A RH-Firewall-1-INPUT -s "SOURCIPADDRESS" -j REJECT --reject-with icmp-host-prohibited it doesn't scale well but servies the purpose. _____________________________________ "He's no failure.

thhis didnt go through completely the first time. I am a bit confused as to how this works. I created a local unpriveleged user (with /bin/nologin shell). i uncommented the line containing nopriv_user=ftpsecure and restarted vsftp. I am confused as to what is supposed to happen. Shuld the daemon /usr/sbin/vsftpd be run as root or should it be ftpsecure? Or is the account only used to

Dear List Users- IHAC planning storage layout and is looking for the following MAX_LUNS size limit on RHEL 3.0 and 4.0. Details are below. Customer database size is estimated to grow to 5 TB and worries that they will not be able to present enough devices to the system if used with EMC powerpath and RHEL 3.0 max_lun limitations. I have advised on using OCFS or ASM as this is a 10g Database

That should say below, we are using Powerpath on the CX300's AND the CX600's... ----------------------------------------------------------------------- We are using Powerpath with CX300's and Emulex HBA's, also with OCFS on Red Hat 2.1 AS. Kernel upgrades are the biggest issue that we have, as some of the drivers are dependent on modules built for specific kernels, and if your

Hi there, have a strange behavior if i?ll create a zfs pool at an EMC PowerPath pseudo device. I can create a pool on emcpower0a but not on emcpower2a zpool core dumps with invalid argument .... ???? Thats my second maschine with powerpath and zfs the first one works fine, even zfs/powerpath and failover ... Is there anybody who has the same failure and a solution ? :) Greets Dominik

Can someone point me to some documentation on how to set up centos 5.0 as an iscsi target? I'm completely new to iscsi so need something basic. _____________________________________ "He's no failure.

I decided to post this question to the mailing list because it needs ZFS knowledge to be solved. The situation is like this: I have a blade server that boots from a LUN, which has no additional storage or internal disk but that LUN used to boot. MPxIO works perfectly; but the management wants to use EMC PowerPath, because the company already has an investment on licensing. After disabling

Is anyone using CentOS 4.4 with an EMC Clariion SAN? In particular, I want to know if PowerPath and Naviagent will work on a CentOS 4 system connected to a san using Qlogic or Emulex cards. I tried a couple years ago with Fedora Core 1 or 2, and couldn't get the kernel modules from PowerPath to work since the kernel wasn't the official RHEL one. I'm most interested in

On some machines running PowerPath, there''s sometimes issues after an update/upgrade of the PowerPath software. Sometimes the pseudo devices get remapped and change names. ZFS appears to handle it OK, however sometimes it then references half native device names and half the emcpower pseudo device names. So the SA can easily be confused. Is there a way to tell ZFS which device names

I have a server that allows incoming traffic for ssh and some other things. I need to set up a rule that will drop/reject all traffic from a particular server except ssh. How can I do that. _____________________________________ "He's no failure. He's not dead yet." William Lloyd George

I was curious if someone on this list has performance numbers with and without PowerPath 3.0.3 on RH AS 2.1 Oracle 9i RAC systems with OCFS. I know that there were some concerns with PowerPath intercepting IO's and slowing performance related to OCFS. Appreciate your feedback. Raj

For those customers that are on this list and are using EMC Powerpath or HP Securepath and have performance problems while using ocfs and point to ocfs first. the actual io overhead for an io on ocfs compared to raw, when it's database io is negligable, we don't do any locking, we have about 40000 clockticks of processing from logical to physical offset, nothingin todays cpu world. Every

A couple years ago, we moved to Oracle RAC on Linux using ocfs that is SAN attached to an EMC CLARiiON. At the time, there was a reason that we did NOT use EMC's Powerpath (I just can't recall what that reason was). What I'd like to know is if there are any issues with introducing Powerpath now. * RHEL 2.1 AS * 2.4.9-e.38enterprise * ocfs-2.4.9-e-enterprise-1.0.13-1 * EMC

Cant find this version. Can some point me in the right direction. _____________________________________ "He's no failure. He's not dead yet."

We have and nfs mount from a windows pc nfs server. A file is created on the server, but can take as long as 50 seconds to become available on the client. We are running Centos 5.2 (final), using NFS version 3. Is there anything we can do from the client side to see the file more quickly. The files are very small, usually about 1k _____________________________________ "He's no

Hello This is a bit off-topic, but here goes: Try installing the "device-mapper-multipath" package and follow the documentation below - residing at the powerlink.emc.com site: "Native Multipath Failover Based on DM-MPIO for v2.6.x Linux Kernel and EMC(r) Storage Arrays" When configured this works just as good as PowerPath. This works great on RHEL / CentOS 5 Daniel On

I just installed EMC PowerPath 5.0.0 and Navisphere Agent and CLI on a CentOS 4.4/x86_64 system. When I try to start naviagent, I get the error below. Before upgrading to CentOS4.4, this same system had RHEL3 ES for x86_64 on it, and the same problem was encountered. I spent weeks going back and forth with EMC tech support, but the problem was never resolved. I'm hoping someone here on this

I've been reading this group for a while and I've noticed a variety of comments regarding running OCFS on top of path-management packages such as EMC's Powerpath, and it brought to mind a problem I've been having. I'm currently testing a six-node cluster connected to a Hitachi 9570V SAN storage array, using OCFS 1.0.12. I have six LUNs presented to the hosts using HDLM,

Xen-users, I have what I think is a bug in the serial console interaction of Xen and Ubuntu. Essentially, the serial console appears to work just fine until it is passed off to dom 0 from Xen. Then it stops communicating with dom0, but still communicates with Xen, if I use the control-A escape sequence. Google will not show me anything related to this. I have local RS-232 serial console working

Hi, We had received a new EMC storage (Clariion CX4) and the EMC analist has told us that CentOS aren't on their support list, but RHEL are :) Well anybody on the list has a CentOS host talking (iSCSI) with an EMC storage, preferably using the EMC Powerpath software, and can talk about you experience? Or I will need to buy some REHL licenses ? I'll put my hands on it only next
