FWIW, I recently solved one reason GMail was always marking my emails as spam: my MTA has IPv6, and to send emails, it was by default using the rfc3041 temporary addresses as source, so each time a different address when connecting to Google's MX's. As soon as I set it up to use the propre static IPv6, marking them as «not spam» in Gmail subsequently worked. So it looks like they also keep track of the sender's MTA address, not only of the email address.

[CentOS] C6 gateway/firewall problem
Hi, I'm using system-config-firewall (C6 x86_64, fully up to date) to configure a gateway/firewall box. 2 nics, eth0 (configured as bridge0, mtu 7200) connected to the lan, eth1 being connected directly to the internet (public ip, mtu 1500). ssh port is open and accessible. nat is working fine. I've put bridge0 as a trusted interface, eth1 is masqueraded. I've put ports 20,21,80 as forwarded ports on eth1 to lan machines. Thing is nmap (and classical ways to access these protocols) say it's closed. I've tried to make 20,21,80 open and forwarded, to no avail. Could someone give me a hand ? Thanks, Laurent. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

You're trying to come in from an outside net to your FW and be forwarded to what you have NAT'd behind it right? absolutely.

Two, at least, and possibly a third over the weekend, of some older Dell 1950's, suddenly died shortly after being upgraded to 5.6. They're all about the same age, and it's not happening with other systems, but they claim a scsi abort, and the f/s goes read-only. The little lcd screen goes orange, and shows a fatal error E 171, and B0 F3 D0? D0 F3 B0? I forget, and won't be able to double check my memory till the morning. Has anyone seen this, with a f/s suddenly going r/o, on machines that seemed to be running fine for years? Since this is two? three machines, that's somewhere between coincidence and enemy action. Probably a coincidence. Last week, I lost 2 disks in the same system in 2 days. The 2nd time, even if RAID 5 status was optimal, it did not handle the loss of one hard-disk. We have a bunch of PowerEdge 1950/2950 running CentOS 5.6. No specific problem since the upgrade (I though about an issue with Squid, but no link with the fact that I upgraded to 5.6). If you have the LCD screen orange, this is an hardware-related issue. Some of them can be prevented/fixed by upgrading firmwares. You can easily upgrade from CentOS using Dell Server Update Utility or Dell Linux Hardware repository.

[CentOS] since CentOS 5.6 upgrade, squid crashes
Hi, I have recently upgraded our web proxy to CentOS 5.6. Before the upgrade, squid was running fine. Since the upgrade, sometimes, squid crashes: [root@stargate ~]# service squid status squid dead but pid file exists Looking at log files, I think it could be related to logrotate stuff, -rw-r- 1 squid squid 42713088 May 3 04:02 store.log -rw-r- 1 squid squid 8192 May 3 04:02 cache.log -rw-r- 1 squid squid 35778160 May 3 04:02 access.log I will look at the latest RPMs to check differences on /etc/logrotate.d/squid.

I'm going to say I need to recompile my kernel and include the module since its present on my box or work out why the newer kernel files are present but not in use?

Has anybody had any experience with that? Any recommendations? Thanks in advance for any and all advice. Boris. Hi, You can take a look at http://www.moosefs.org. It is a network, fault-tolerant FS, posix compliant, allows snapshots, uses fuse, your code doesn't need to be changed to access the FS. You can easily choose the number of replicas of files/dirs you want. It is easy to deploy, runs in user-space. Some people runs it successfully on 500+TB. Plus, I've made a CentOS repo here: http://centos.kodros.fr/moosefs.repo Regards, Laurent pgp0aZsiashVc.pgp Description: PGP signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] MooseFS repository
Hi, A repository for MooseFS is just born. It provides CentOS 5.5 SRPMS, i386 and x86_64. cd /etc/yum.repos.d/; wget http://centos.kodros.fr/moosefs.repo ; yum install mfs Two points: - DNS may not be up to date where you are. The subdomain has just been created. Please be patient. - I have made an update to the .spec file, to move config files to /etc/mfs instead of /etc. I had no time to test it yet. I guess it works :) What is MooseFS ? MooseFS is a fault tolerant, network distributed file system. It spreads data over several physical servers which are visible to the user as one resource. For standard file operations MooseFS acts as other Unix-alike file systems: * A hierarchical structure (directory tree) * Stores POSIX file attributes (permissions, last access and modification times) * Supports special files (block and character devices, pipes and sockets) * Symbolic links (file names pointing to target files, not necessarily on MooseFS) and hard links (different names of files which refer to the same data on MooseFS) * Access to the file system can be limited based on IP address and/or password Distinctive features of MooseFS are: * High reliability (several copies of the data can be stored across separate computers) * Capacity is dynamically expandable by attaching new computers/disks * Deleted files are retained for a configurable period of time (a file system level trash bin) * Coherent snapshots of files, even while the file is being written/accessed For more details, see http://www.moosefs.org Feedback welcome !

Re: [CentOS] Slightly OT: check creation of a group
2010/3/1 Niki Kovacs cont...@kikinovak.net: Hi, I'm currently writing an install script for an application, and my already limited Bash skills are a bit rusty. I want to check if a group exists, and if it doesn't, then create it. Only thing I found is: if [ grep medintux /etc/group ]; then continue else groupadd medintux fi Apparently I can't seem to negate the test, e. g. something like if !(grep medintux /etc/group) Any suggestions for the correct syntax here ? Thanks, Niki Why don't you use groupadd -f ? It will not override the group if it already exists, and shortens the code :) Laurent ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Updating gfortran in CentOS 5.4?

I wonder if that rpm allows the version of gfortran and associated libraries it installs to be located in something other than the default location. This is important because I don't want to remove the standard version of gfortran in case something goes wrong. (I know that the rpm command can do this but some rpms don't allow it). Thanks for the suggestion. I'll try this. gcc44 and gfortran44 are specially crafted to be installed without removing official version of gcc/gfortran. executables names are gcc44 and gfortran44.
