I have installed Enterprise Ruby and Passenger, but as far as I can recall, this still required building from source and using RubyGems to update the passenger gem. Even if an rpm solution was available, I do not consider this the preferred way to go when supporting a Ruby installation dependent upon gems. Gems are the canonical method of maintaining Ruby library extensions and it seems self-defeating to require further re-packaging. Sincerely, -- *** E-Mail is NOT a SECURE channel *** James B.

Still Confused about Firewalling
by ML 19 Oct '09

19 Oct '09

Hi All, Sorry, I am still confused about implementing a firewall without having my ISP static route all of my traffic to my public IP's to a single public IP. So before when I have done this for work all traffic has been statically routed. Now I have a comcast modem and it is 'pass through' so traffic for all my 13 IP's is allowed and I have to decide what to do. So I am looking at Vyatta or UnTangle. I have a machine with 3 NIC'e in it. I think one would be In, DMZ and last private. What happens? I have one cable from my comcast gateway to my firewalls NIC, but how does it answer for all IP's that I have so i can evaluate the request incoming to a rule set and decide if allowed or denied? I am missing something fundamental! Can anyone help this click in my head? Without statically routing my traffic I dont get it. Say a request comes to my webserver 172.13.167.xxx on port 80, but my firewall's IP for the card is 172.13.167.zzz how does it answer for 172.13.167.xxx? -Jason

update of openssh-server i386 4.3p2-36.el5, dependencies
by zagiatakrapovic＠gmx.ch 19 Oct '09

19 Oct '09

so far: - not a yum bug - not a configuration issue - other persons could reproduce this behaviour even under RHEL right? so this backport is actually broken or let's say the guy who did this, improved encryptFS-utils that much, it uses now X11 libraries even if it actually has no GUI... still right? ok, so now what is the next step? There is a ticket for this issue but it is reported as a yum bug (see my last post). we all just wait until somebody kicks some #$!@ of the responsible code monkeys? -- Jetzt kostenlos herunterladen: Internet Explorer 8 und Mozilla Firefox 3.5 - sicherer, schneller und einfacher! http://portal.gmx.net/de/go/atbrowser

Re: [CentOS] Backing up a centos serveR? how to ? Newbie question..

A really good place to find out info about the various raid levels and what their good for is here: http://www.acnc.com/04_01_00.html But please don't confuse raid with something like Bacula :) Regards Per At Monday, 19-10-2009 on 16:28 "Bobby" wrote: On Monday 19 October 2009 08:56:48 RedShift wrote: > David Suhendrik wrote: > > may be rsync help You > > Or u can try raid 0[mirrorig] > > for replicate failover triying drbd and heartbeat but I've tested and > > unsuccessfull on my zimbra machines > > RAID IS NOT A BACKUP. > > I repeat. > > RAID IS NOT A BACKUP. > > Nor is replication. Exactly. RAID above RAID 0 does provide redundancy towards hard disk errors. It makes the system more robust. But the data is still in the same set of drives. Backup, as with scp, rsync and cron to a different computer is what you need. We backup our computers every hour with the above. It's very low impact and all we can loose are some changes in the last two hours if the system dies during rsync. David, RAID 0 is not mirroring. What it does is extend capacity over two or more drives. RAID 1 is mirroring.

Backing up a centos serveR? how to ? Newbie question..
by RoLaNd RoLaNd 19 Oct '09

19 Oct '09

Hi all, excuse my newbie question but how can i backup my centos server? i have a dozzen of virtual hosts over it as well as substantial database entries.. i've backed up the following directories using rsync: workspace/ /etc/httpd/ /etc/apache-tomcat-6.0.20/ /usr/lib/mysql/ /var/lib/mysql though i'm still not at ease with this, so i decided to do a some sort of clone or something to move this server to a VMWARE which i will turn on when needed (if main server failed) any advice on how to do so ? i've looked around and tried using "clonezilla" though that didn't work with me, i guess i mustve done something wrong... each time i try to boot from the cloned image of the local disk (which in turn cloned to the VM's local disk) it gives an error bout root records... so any other way ? any sort of help is greatly appreciated :) thanks and best regards, Roland _________________________________________________________________ Keep your friends updated—even when you’re not signed in. http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/so…

[OT] DHCP auth&auth software
by Marko Vojinovic 19 Oct '09

19 Oct '09

Does anyone know about some free (as in beer, and maybe as in speech) software which would implement authentication and authorization of a user prior to issuing a valid dhcp lease? I imagine the following scenario: someone walks into my office building with a laptop (a colleague, a visitor, a guest, whoever), and hooks up onto the local net (wired or wireless). The server detects an unknown MAC address, issues a bogus dhcp lease which resolves all dns queries to a single internal web page with a form the user is supposed to fill in and send. After he does so, an administrator does a sanity check of the data the user provided, and grants or denies access. If access is granted, the user gets a new, unrestricted dhcp lease, which provides him with a normal access to local network. The goal is to have a database which relates IP or MAC addresses to people names, so I can track a person down efficiently if he brings an infected/spamming machine into the building. I would know how to build this infrastructure manually, but it's a lot of work, and I don't want to reinvent the wheel. Google somehow failed to help, or I failed to provide the right keywords. :-( So what are my options? TIA, :-) Marko

the ongoing wait for centos 5.4
by Robert P. J. Day 19 Oct '09

19 Oct '09

at the risk of picking at that scab a bit longer, i'm going to toss out a comment regarding people still waiting for the public availability of centos 5.4. here: http://lists.centos.org/pipermail/centos/2009-October/083743.html we read: "The last status (from twitter) is 2 days old with the '5.4 is baked! centos internal network will start syncing up today. Release ~ soon!'. Any ETA?" followed by the response: "Just relax and wait, this is a _volunteer_ based project. Want a release date? Go pay for RHEL." not to put too find a point on it, but that reply is more than a bit dickish. it doesn't *matter* if it's a volunteer project. as i see this, this is turning into an issue of credibility. once someone posts that the 5.4 release is allegedly "baked" and syncing is beginning, then it's not unreasonable that people will start getting anxious to see it hit the mirrors. and as the days go by, it's not unreasonable for those people to start wondering what the heck is going on. again, whether people are being paid to do any of this work is not relevant. it's important, from the perspective of reputation, that everyone see the centos project as being efficiently and competently run, and making what *appears* to be an announcement of completion and the beginning of syncing servers, followed by days of awkward silence and increasingly defensive rhetoric, is not the way to do it. it just looks bad. rday -- ======================================================================== Robert P.

trying to understand OSS, GPL, BSD & other licensing model for software distribution.
by Rudi Ahlers 19 Oct '09

19 Oct '09

Hi all, We are busy developing some software (some is web based, others not) and I am having a bit of hard time understanding (or rather, choosing) a license model to work with, We will offer some free software (PHP based scripts, and even Windows based applications) and for this I'm sure the GPL, or even LGPL (for the network side?) will work fine. But, we also need to suppose these scripts, and will be charging for support (other for installations, customization, or even custom derivations, etc), but at the same time we need to distribute some commercial software to cover developer's salaries, rents, marketing, business growth, etc. Now, my question(s) is as follows: Can I sell one script as GPL, but another as AGPL, or even BSD under the same company name? And if these 2 are tied together (i.e. being able to be used together, although seperate programs / script - for example Apache + PHP), how would I license them? We are writing a series of PHP + MySQL based scripts which can be used on the internet, either stand-alone, or in conjunction with other scripts (API driven), and I want to offer a free, limited edition, as well as commercial edition with more features. We're also writing some software that makes use of MySQL / sqlite / postgresql, and even MSSQL, so I need to take their licenses into consideration. What would be the best license for this? I know it's broad, but there's just too much to readup on the different licences and I've read a lot already, not knowing where to go. I have a feeling that I may need to go the dual / multi-license route, but even then I don't know which licences to use. The open source projects wouls also be open for other people to add their own modifications, but I would also like to allow others to write commercial addon's as well. Any pointers, and even past-experiences? -- Kind Regards Rudi Ahlers CEO, SoftDux Hosting Web: http://www.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532
