We also had it updated and fail2ban worked perfectly except it did not
ban anymore on the sshd jail. This was caused by the
/etc/fail2ban/filter.d/sshd.conf file which should have been replaced
with a new one from the rpm (there was a sshd.conf.rpmnew file).
Below the error we found in /var/log/fail2ban.log :

Re: [CentOS] rescue - UEFI revert to BIOS boot - how?
Hi, I had the same sort of issue. My workstation with a Asrock motherboard suddenly decided to reset UEFI to defaults which caused my Fedora installation not to boot. I could boot with a Live USB stick and use efibootmgr to set the UEFI boot for Fedora but next time I powered on my machine the same issue happened (I remove AC power from my workstation when it is not in use). Turned out to be a flat battery for the BIOS (coin cell). I replaced the coin cell and set the UEFI boot with the Live USB stick and all was well. The efibootmgr command was something like : efibootmgr -c --part 2 --loader /EFI/Fedora/grubx64.efi --label Fedora Please check the manpage of efibootmgr, the process of how to setup the UEFI boot is described very well.

If the OS was installed with UEFI enabled I would go back to UEFI mode. Then re-add your OS boot configuration within the BIOS setup screen. Most motherboard manufacturers detail this process on their website where you browse the disk to select somefilename.efi and give it a label “CentOS”. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Corosync init-script broken on CentOS6
Hi, Did you configure corosync ? Normally corosync starts pacemaker, which in turn starts the heartbeat deamons. But you have to configure the latter using for example a pcmk file with configuration in /etc/corosync/conf.d/ (from the top of my head). I normally use : http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Clusters_from_Scratch/ Regards, Michel On Wed, 2011-11-23 at 12:16 -0500, Hal Martin wrote: Hello all, I am trying to create a corosync/pacemaker cluster using CentOS 6.0.

Re: [CentOS] tar-ing subdirectories separately
Hi, I want to backup a directory using tar, but want separate tarballs for each subdirectory. For example: # ls dir1 subdir1 subdir2 subdir3 Will it possible to do it using only tar command? Or will I need another separate piece of logic/control? I thought of writing a shell script with three tar commands for each subdirectory, but that's not elegant way of doing it. Also, it may not scale as number of subdirectories change. Any other solutions or tips for doing this will be really helpful. You can try something like : find /dir1 -type d -print -maxdepth 0 | while read DIR ; do tar cfv $DIR.tar $DIR/; done not tested, just off the top of my head and it's late, so if it breaks, you can keep and be happy with all the pieces ;) Regards, Michel ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I use a fast mirror and d/l overnight with a wget bash script, run by cron. I have downloaded hundreds of DVD iso images with wget and curl during the past years. I had maybe one or two that were corrupted in one way or another, mostly because of improperly configured (windows) webservers. 4Gb with HTTP is no problem nowadays, FTP isn't either. If you have doubts about HTTP/FTP you can always use the Bittorrent way to download (also with commandline tools like btdownloadcurses or similar). It doesn't really matter when you download them although in some cases it can make a difference in speed to download overnight but with most tools you can also specify a maximum bandwith to use. To be sure an image is ok you can always check the image with the md5/sha1 checksum which is normally found in the same directory as the image on the HTTP/FTP server. kind regards, Michel ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

If you should use them in a PCI slot yes, not if you use them in a PCI-X or PCI-e slot (although you could saturate a PCI-e x1 with 4 gbit ports I think). Depends mostly on if you are using PCI/PCI-X vs PCI-express. At high bit rates you can saturate the old PCI bus. A single gigabit port can pretty much saturate a 32-bit PCI bus at 33MHz. PCI-express can go a lot faster. The Intel Quad cards don't fit (and don't then) in a single PCI slot.

The IP numbers are X.Y.Z.170, .171 and .172 All three machines have MX records. they all have the same domain name. There's your error, the new one shouldn't have mx records for the domain if they are not designed to accept mail for that domain.

Is there a way to do that - or am I going about this the wrong way? There is a way but maybe there's a quicker (and dirtier) way. Just reconfigure sendmail on the two new machines to *not* listen on the public ip on the smtp port.

Re: [CentOS] company exchange server exim best practices.
Hi, my solution to this kind of problem is the following : Set up a relay mailserver (in my case Postfix) which accepts mail (and has the MX record for the domain) for the domain but has no mailboxes. Postfix takes care of spamblocking (dnsbl and spamfilter ). In Postfix I use a transport table to relay the mail to the Exchange/Whatever mailserver, that can also be on a nonstandard port (in my case port 2525). Delivering to a dyndns host is really easy, Dyndns uses a short ttl for the hostname (something like 3 minutes ?). I set up a nameserver record which let a 'fixed' name (like mail.domain.nl) point to the dyndns name using CNAME. mail.domain.nl. IN CNAME mailhost.dyndns.org Sending the mail to the dyndns hostname directly without the nameserver trick is also possible. Using a non-standard port is to bypass SMTP limits from the provider and to make (almost) sure your mail doesn't get delivered to a mailserver of someone else ;) Regards, Michel On Fri, 2009-04-03 at 09:40 +0200, Rudi Ahlers wrote: Hi all, I hope this isn't too OT, but since I use a CentOS5.2 + Exim mail server (which is hosted in one of our data centres) I don't think it should be. On of our clients use an MS Exchange 2003 SBS server, with exchange for their internal email. We provide them with a domain, ADSL (which uses dynamic DNS) and POP3 email. They don't have an spam filter program on the exchange server itself due to costs, so I have setup each user on the Exim server, which runs ASSPX for anti-virus / spam filter / etc. Then I setup the SBS 2003 server to pull the email via POP3, but this doesn't seem to work too well, cause the exchange server doesn't always download the POP3 email, and then the users often sit without email until I go there to manually download the mail again. I have tried changing the MX record to point to their DynDNS address, and it works well, but then they get a lot of spam. And the cost of a server-side spam solution is just too expensive, and they also pay for the bandwidth uses when spam comes in. So, I moved their MX record back to the Linux server. But now I sit with the problem of the POP3 connector failing from time to time. So, I would like to know, is there a way to push (not forward) mail from the Linux server, after it has arrived and spam been blocked, to another domain, but with the same email address? i.e. the domain in question is attorneys.co.za and I've setup attorneys.dyndns.net as the dynamic domain, but the exchange serves email for attorneys.co.za Forwarding email doesn't work, since there's no such user as b...@attorneys.dyndns.net, but rather b...@attorneys.co.za. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] pop3 attack
Hi, RR charges you an extra $50/mo for static ip! I don't have many other choices for a decent high speed connection. DSL is too slow in my area. We have some ISP's here in the Netherlands which have spam relayed through their mailservers, which gives the same problem, blacklisted smarthosts of big ISPs. One way to get around it is to get yourself a VPS (virtual private server) for a small amount ($20/month?) and set up your own 'smarthost' (maybe together with some friends/coworkers?). You can then even use a non-standard port to relay your mail through it and even encrypt if you wish. I have my smarthost set up at such a server because my laptop goes around different networks and isps and I don't want to change my configuration every time :) regards, Michel ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

There are rpms of it and clamav in the rpmforge repo. I use a combination of Postfix with rbl, spamassassin, clamav and amavisd. It filters about 95-98% of my spam. I also have a spamcop account to report the spam that gets through. Regards, Michel ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] xinetd question

How does one restart xinetd? On a CentOS 5.1 system, xinetd is not installed by default and thus not startable. You should first install xinetd using 'yum -y install xinetd'. Then you can restart xinetd. Where do you need it for ? Regards, Michel van Deventer ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] SSl Certificate problem
Hi Tom, the location of SSL certificates changed from C4 to C5, certificates are located in /etc/pki/tls on C5. Apache is also a newer version on C5 (2.2 , 2.0 in C4). You should check your configs manually and change them accordingly. I can help you if you post your C4 config. Regards, Michel van Deventer On Fri, 2008-03-28 at 18:37 -0400, Tom Diehl wrote: Hi, I have a c4 server that I am trying to migrate an ssl site over to a new C5 machine with all of the updates. The certificate is an equifax cert and works as advertised on the C4 server. When I move it over to the C5 machine I get error in firefox that says error code -12227 which http://www.mozilla.org/projects/security/pki/nss/ref/ssl/sslerr.html says is an SSL_ERROR_HANDSHAKE_FAILURE_ALERT. In addition it says that this means that SSL peer was unable to negotiate an acceptable set of security parameters. If I try to open the site in IE, it prompts for a client certificate. This fails because I am not using client certs. In the apache config for ssl.conf I have SSLVerifyClient none. I have also tried setting it to optional with the same results. In the past moving these sites to a different machine was as simple as copying the certs and the config files over to the new machine, reloading httpd and everyting just worked. Is there something different about ssl on C5? Does anyone know a good way to troubleshoot this. Google and the docs are not helping. What am I missing?

Re: [CentOS] how do I run something on a newly installed server, on it's 1st boot only?
Hi, you can use the %post part of the kickstart for that, then your script will run after installation is complete but before the reboot. If you need to run it after the first reboot, I'd put it in /etc/rc.d/rc.local and let it remove itself after running succesfully. And of course copy the script to the server using the %post part of kickstart ;) Regards, Michel On Sat, 2008-03-29 at 09:11 +0200, Rudi Ahlers wrote: Hi all I'm busy with a kickstart file to automate server installations, and I need to run a bash script right after the server has been installed for the first time.

Re: [CentOS] Allocaation resource error (DELL Optiplex 755)...
Hi, I had EXACTLY the same problem, running Fedora 8 (64-bit) on a Optiplex 755 with 4Gb and a 8600GT. You should update you DELL bios to rev A07 (released about a month ago) then it works.

Re: [CentOS] Using tcpdump to sniff telnet password
Hi,
you should set the snaplen (length of packets to be captured) to 0 (max
packetsize) like :
tcpdump tcp port 23 -s 0 -w test.txt
Otherwise you won't get the full packets.
And you can use wireshark to read the dumpfile and easily find the
password(s).

No, you cannot run IA64 on a Core2Duo, you need the AMD64 or x86_64 version. Are there any differences in basic libraries between 4.0 and 4.5?
