[CentOS-es] backup con bacula
Saludos ante todo. En la empresa tengo instalado CentOS 6.3 en la gran mayoria de los servidores, pues he ido migrando poco a poco de windows a centos. Quiero realizar copias de seguridad de todos los servidores. He estado buscando y leyendo y di bacula, que dicen que es muy estable y robusto y por tanto me gustaria implementarlo, pero no encuentro alguna guia para realizar la instalacion y configuracion de bacula. Alguien me puede indicar donde encontrar estos materiales, si es que existen?? Si hay otra sugerencia mejor que bacula, tambien es bienvenida.

Sure, but how can I update rubygems installed in one system?? The main problem with RHEL and Ruby on Rails is that the version of Ruby available for EL6 from reputable repositories is too old.

Thus, a RHEL/CentOS rpm package for Rails really will not give you much, if anything. I suggest that you investigate both RBENV and RVM as alternatives to using the rpm packaged Ruby. I advise you consider that for RoR projects the Bundler gem is the preferred way of installing and managing project specific packages, including Rails itself. The down side to this approach is that your production servers need to have development tools installed to build the Ruby interpreter and the support gems. The up side is that you can version specific ruby vms and gemsets on a project by project basis. https://github.com/sstephenson/rbenv https://rvm.io/ http://gembundler.com/ I used rvm almost from its inception but have recently changed to rbenv as this has a much smaller footprint on the user's environment.

The next release of ruby? from RH? will be the 1.93 or some such, and include all the stuff in the enterprise version. Development tools on a production box are a very, VERY bad idea. I assume you can build the ruby app on your development box, and then move it as a package to test, then prod. I've also seen an article or two about ruby not scaling up well. From my experience here, the apps seem to be *very* fragile, and it reminds me of python 10-12 years ago, where updating it one or two subreleases broke everything that had been working, including system tools.

[CentOS] Slow login to system without internet connection
Hi. For a long time I am puzzled why, when internet connection is gone (beyond first router, outside of subnet) SSH (and telnet?) connection is drastically slowed. Same behavior, but less impacted is observed when system boots without working internet connection, and I am not sure, but I think even access to SAMBA fileshares can be/is affected. Affected systems are mostly production servers, and too spaced apart in time to be able to point a finger in something I am doing wrong. I have not had time to gather more facts, I always forget/don;t have time, so I will only focus on definite SSH issue on CentOS 6.3, although I have seen same with 5.x. 1 server in question is set in following maner: [root@chiron ~]# cat /etc/networks default 0.0.0.0 loopback 127.0.0.0 link-local 169.254.0.0 [root@chiron ~]# cat /etc/sysconfig/network NETWORKING=yes NTPSERVERARGS=iburst HOSTNAME=chiron.example.com [root@chiron ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 chiron.example.com chiron ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 chiron.example.com chiron Does it have anything to do with /etc/hosts file not having row with used IP address, or is problem somewhere else?

I have a small WISP. I get my internet connection vai several wireless links/towers. My main server is located in my house. My own PC and the Server in question (in the example) are separated by a router in my house (different subnets). Server is fresh install of CentOS 6.3, all updated. Now, when there was power failure (works on the transformer there), I lost my internet connection, but router and wireless routers for the rest of my towers were accessible.

It is in-house connection, so there is nothing to traceroute. Past experience was, separate from this example, that a CentOS 5.x server in one company slows access, temporary timeout to SAMBA file server when wireless router connecting them to internet is turned off, although they are in local lan with static IP's. -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe Google is the Mother, Google is the Father, and traceroute is your trusty Spiderman...

Re: [CentOS] How can I prevent apache from mounting all home directories? [SOLVED]
On Nov 19, 2012, at 11:14, I wrote: We use automounted user home directories on our CentOS 6.3 desktops, and on the desktops on which we start apache, I have noticed that all 900+ home directories listed in NIS get (and stay!) mounted. If I don't start apache, this doesn't happen. After trying and failing to reproduce the problem on a test RHEL 6.3 server, I compared the apache configs on the two servers and noticed one difference: the CentOS system had mod_dnssd installed. After doing a yum erase mod_dnssd (which also removed gnome-user-share) the issue went away. Problem SOLVED!

So the question is: is there a setting that will reduce that DNS timeout for all running services, maybe like a ping-watchdog that would recognize the problem and skip the reverse-DNS lookup if DNS servers are not reachable? How about adding zone files for the things that belong to you? I've always been surprised that distributions that contain name servers don't include dummy reverse zones for all the private IP ranges. It must make a huge load on the DNS infrastructure when everyone passes those queries upstream where they will always fail (but quickly...). You'd get the same answer even faster if you had an empty zone file yourself. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Slow login to system without internet connection
Hi Ljubomir, But when I tried to login to my server, it was not instantenous, and I think it was 15+, maybe even 30+ seconds (I forgot to time it) from start of ssh command to password prompt. It is in-house connection, so there is nothing to traceroute. are you using an external DNS server that is reachable via the internet only? If so, edit /etc/ssh/sshd_config and change this #UseDNS yes to UseDNS no Then restart sshd and see whether it still happens. sshd tries to look up its counterpart's host name using DNS in the default setting, and if DNS is not reachable it waits for the request to time out.
