Gracias por la colaboración Ahora entendí... :) Desde mi punto de vista el problema debe de estar en el gateway... que no hace puente desde la entrada de Internet a la red interna. En este momento no se me ocurre en donde mirar especificamente... pero para mi vas a tener que mirar el ruteo interno... entre la salida dela VPN (hacia la re3d interna) y la lan interna.

[CentOS] udev works ok in CentOS 6.x??
Hi all, I have strange problem with my persistent names applied to iscsi disks.

I changed it a bit since then. I found that sleep 1, when talking to my other
VM that had
sleep 1, caused one mail to just get lost, so I dropped it.
My brother travels a lot and I found the client restrictions would not allow him
to send mail since the wi-fi he would connect to was not figured correctly
causing
100% mail send failure. So I left client restrictions empty, but I force ssl
and user auth
only anyway.
for the rbl lists I tried to pick those that had a notice page and a remove
page.
This way a blocked user can try to figure out why.
Here is a bit from my logwatch, with 8 hours of non blocked spam and 16 hours
since blocking it
6098 rejected, 429 accepted (most of those 429 were before the change)

[CentOS] yum list installed - 3rd column
On most of the CentOS 5 machines I manage, if I run yum list installed the third column just says installed for all packages. But on one machine, some lines show instead a repo name preceded by an @ sign. Apparently the repo from which the package was installed, which would be immensely useful. Two questions: 1. Can I have that feature on the other CentOS 5 machines too? The machine in question has yum version 3.2.27-12.el5_from_el6 while all others have version 3.2.22-39.el5.centos. Where did that el5_from_el6 version come from? The yum list entry for yum itself does unfortunately not show a repo name. 2. Can anything be done about the lines still saying only installed? How do find out where those packages came from? aTdHvAaNnKcSe Tilman -- Tilman Schmidt Phoenix Software GmbH Bonn, Germany ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] 6.2 kernel issues
A couple weeks ago, after we moved a user's home directory from a 5.7 box to 6.2, he came to complain about slowness. Unpack file from NFS-mounted directory to local disk, like /tmp, everything's normal. cd to the NFS-mounted directory, and unpack it there, and it was six to seven times slower. We repeated this a number of times, on a number of machines. At first, we thought it was an NFSv4 issue, and I filed a bug with RedHat about it. Then we did more testing; it seems to occur with 6.2; it's going to happen if that's got ext4. However, my manager saw something else, just today: he noticed one of our nightly backup servers was taking much, much longer to complete the rsync and delete. Then he saw that I'd updated that backup server to 6.2, and after the backups started running again (probably missing modules), they were taking a lot longer... about 6-7 times longer. As in going from between .5 and 1 hr, to 5.5 to 9 hours. Anyone else seeing this behavior? mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

It appears that only sshd is affected. All other services seem to work on both v4 and v6. I have it listening on a non-standard port other than 22.

[CentOS] debugging RAM issues
Hey folks, I have 1 system ( Sunfire x2250 running 5.7 ) that is having issues with RAM, but I'm not sure how to debug it. And unfortunately it is not under support anymore. I started the job about 4 months ago and when I came aboard the guy who handed stuff over to me told me this issue was on his list of things he was unable to get to yet. He told me he'd seen errors in the past in the Sun ILOM message log, but unfortuantely he did not record exactly what the messages were. Fast forward a bit and I've had problems with this machine. Sometimes when I reboot it, it just won't come up. The console and everything just go completely dead no matter what I do. I unplug it for a while and try again, same thing. It seems to just randomly come back to life, and when it does I see something in the ILOM log like this : ID = f74 : 03/07/2012 : 19:17:42 : System Firmware Error : ACPI : No usable system memory So it seems to me that when it is having trouble, it is not seeing any RAM at all. And when it does come back up, Linux only sees half the RAM it is supposed to see. lshw sees all the RAM The only errors I see in the ILOM logs are above. I don't see anything in dmesg or /var/log/messages on the Linux side. Back about 3 months ago I took this system down and removed all the RAM, and stuck individual chips into it and booted it, testing each chip on its own. At that time every single one of them worked! But I'm about to try this again to see what happens. Back then I also ran memtest86 for some time and it seemed OK too. Other than that I'm a bit stumped on how to get to the bottom of this. Tips? I googled the error and got precisely 1 hit at a university high performance computing center in Utah, so I dug up a contact there and emailed them hoping they could tell me something, but I have not yet heard back. thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of In Defense of Food ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The reality is that what is need is to input this into a scoring system weighted with other spam evaluation mechanisms, something like spamassassin. The downside of spamassasin is that it is costly to run and must be run after the message is accepted by the smtp server. There already exist so many different spam control methods, many of them can run at the smtp level and reject mail prior to accepting. I get pretty decent rejection from greylisting. Postscreen is supposed to be quite good for detecting any kind of bot attacks. I'm currently using other techniques for bot attacks, but plan on switching to postscreen. I also run fail2ban and block IP addresses when I get repeated smtp errors from an IP, this substantially reduces any kind of bulk spam attack which attempts to guess valid mail recipients.

/pbl.spamhaus.org (dynamic IP address RBL) is generally quite safe for
most sites to use from postfix. The rest of the spamhaus RBL's such as
the combination that you get from zen.spamhaus.org are mostly safe
(better than all others that I've tried), but not 100%. Most others
that I've tried I have gotten a fair number of false positives over time
(This includes dul.dnsbl.sorbs.net, the sorbs dynamic IP RBL). Many
people feel that most other RBL's need to be used with a scoring
mechanism, such as that provided by spamassasin, instead of directly
from postfix to avoid getting too many false positives.
Nataraj
I changed it a bit since then. I found that sleep 1, when talking to my other
VM that had
sleep 1, caused one mail to just get lost, so I dropped it.
My brother travels a lot and I found the client restrictions would not allow
him
to send mail since the wi-fi he would connect to was not figured correctly
causing
100% mail send failure. So I left client restrictions empty, but I force ssl
and user auth
only anyway.
Mobile clients should be authenticating to a relay that's not on any of
the dynamic lists and sending mail out through there. Most sane mail
administrators do not accept mail directly from dynamic broadband/mobile
clients.
for the rbl lists I tried to pick those that had a notice page and a remove
page.
This way a blocked user can try to figure out why.
Also anyone using rbl's should also review the RBL's policy. Most RBL's
charge a license fee for high volume queries and will cut you off if you
violate their policy.
Here is a bit from my logwatch, with 8 hours of non blocked spam and 16 hours
since blocking it
6098 rejected, 429 accepted (most of those 429 were before the change)
Since 12 noon yesterday I have received 17 junk mails, all but two tagged by
spamasassin.
BIG DIFFERENCE.
Below is the logwatch section, followed by my final set up (at least so far).
Your logwatch format is very nice, that does not appear to be the
standard CentOS included logwatch. Have you customized it alot yourself?
In any case, I used to have very large numbers in the category you
described, but since I started doing agressive blocking with fail2ban
(matching on repeated mail delivery failures), now I just completely
block all those with IPtables, so that postfix never sees them. I have
not noticed any increase in user complaints since this happened. And I
do notice that the majority of the offending IP addresses were from
asia, south america, eastern Europe, the middle east, etc.
Is this just a personal mail server or are you serving a large user base?

In my experience, the long-term stability of DVDs is rather questionable. I've had quite a few nasty surprises with DVDs. Even single-layer ones regularly turn out to be unreadable after two or three years, and double-layer ones are worse. I don't know if Blueray is any better in that respect. Yup. I've been reading about that instability for several years now: the commercially-produced ones are ok, but not the ones you write; they will *not* last the same number of years. mark mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos Good point. I've been following the recommendations in articles such as this http://adterrasperaspera.com/blog/2006/10/30/how-to-choose-cddvd-archival-media/ using mostly the Taiyo Yuden and verbatim media where I could identify the country of origin and the dyes and so far I've done ok. A good reminder for me to check some of my back archives. I also have this same data stored on hard drives, so there is redundancy. As some have pointed out, if you really need long term archival of data I think a good plan would include periodic testing and refresh of media or rewrite to new media.

[CentOS] perl-DBD-MySQL, libmysqlclient.16 and 5.7 (FInal)
Hello, I have server CentOS 5.7. It has mysql-community installed. I need to run perl-based tool (mysqlreport) and it requires perl-DBD-MySQL (not a surprise) When I am trying to install perl-DBD-MySQL via yum -- it says it requires libmysqlclient.*15 *and it conflicts with libmysqlclient.*16 *which was installed as a part of mysql-community. I tried to make symbolic link and force DBD to work with 16. But it failed with error. Looks like libmysqlclient provides it version or has different API (which is strange for me) The only one idea I have is to fetch libmysqlclient.15 from some packet and put it to my LD folder directly. But what has happened? Where is DBD for new version (16)? What is the best (official) way to solve it? Thanks. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The permissions of the files in /var/spool/cron are: # ll /var/spool/cron total 12 -rw---. 1 root root 34 Mar 9 16:41 root -rw---. 1 root root 4245 Mar 12 14:53 theheart According to the man page the crond daemon requires that root own everything in /var/spool/cron (unless run with the -p option) and that no one else may have write access to the files therein. The file names also must match a user id in passwd to be loaded and used by crond. Thus there was no issue with either the permissions or ownership. The other difficulties that arose had to do with PostFix configuration. Since on this host there is no local mail delivery the aliases map is simply not used by PostFix. Therefore entries in that map have no effect whatsoever. The virtual map is used by PostFix in this case however. Thus entries made in the virtual map can be used to route locally generated mail sent to local userids even with local delivery disabled. -- *** E-Mail is NOT a SECURE channel *** James B.

[CentOS] 6.2 kernel issues - followup
I wrote: A couple weeks ago, after we moved a user's home directory from a 5.7 box to 6.2, he came to complain about slowness. Unpack file from NFS-mounted directory to local disk, like /tmp, everything's normal. cd to the NFS-mounted directory, and unpack it there, and it was six to seven times slower. We repeated this a number of times, on a number of machines. At first, we thought it was an NFSv4 issue, and I filed a bug with RedHat about it. Then we did more testing; it seems to occur with 6.2; it's going to happen if that's got ext4. However, my manager saw something else, just today: he noticed one of our nightly backup servers was taking much, much longer to complete the rsync and delete. Then he saw that I'd updated that backup server to 6.2, and after the backups started running again (probably missing modules), they were taking a lot longer... about 6-7 times longer. As in going from between .5 and 1 hr, to 5.5 to 9 hours. Well, I was googling on performance tuning NFS, and found http://www.softpanorama.org/Net/Application_layer/NFS/nfs_performance_tuning.shtml, where the author notes One issue with migrating to NFSv4 is that all of the filesystems you export have to be located under a single top-level exported directory. This means you have to change your /etc/exports file and also use Linux bind mounts to mount the filesystems you wish to export under your single top-level NFSv4 exported directory. I makes a *real* difference. I tested it, on one 6.2 server, mounting a foo directory I created in the usual 3 levels deep, and another, /tmp/foo1, and doing my same unpack ran at 2/3rds the time. Not good - 6.5 min vs. 1+min for 5.7 NFS3, but better. This alone suggests we need to go back to NFS 3 - it would be a Big Deal to relocate everyone's home directory. Doing a yum list \*nfs\* shows something called sblim-cmpi-nfsv3.x86_64. From the info, I can't tell if I can just drop it in and run that, or if I'd have to yum remove nfs-utils nfs-utils-lib.

Re: [CentOS] CentOS Server Backup Options
here's my tentative plans for a d2d backup in my lab. 2 identical servers, each with lots of SATA bays. each server configured with 2 raids, raid1 is this servers storage, and raid2 is a DRBD mirror of the other servers storage. each server runs KVM and under KVM runs a CentOS virtual machine which runs BackupPC, that has half the backup jobs assigned to it. if server2 fails, then server1 fires up the backup2 VM on its DRBD replica of server2's storage, and all continues as it was, with just less performance until the 2nd server can be restored, and the backup2 volume replicated back to it so the backup2 VM can be stopped on server1 and resumed on server2. this doesn't address offsite archiving, and I haven't quite decided if I'm going to A) replicate the important backups to additional offsite storage, or B) periodically make archive backups onto a separate HD that is then dismounted and pulled and shipped to the data vault (the production IT at my site has weekly drops to a data security company, I could add a disk to their lockbox.

At least from what I read, the failure rate is much lower for the same drive used under the later conditions. Even so, I still choose multiple different backup format.
