Hi, From RHEL 6.1 Release note : "Red Hat Enterprise Linux 6.1 features IPA as a Technology Preview. IPA is an integrated security information management solution which combines Red Hat Enterprise Linux, Red Hat Directory Server, MIT Kerberos, and NTP. It provides web browser and command-line interfaces, and its numerous administration tools allow an administrator to quickly install, set up, and administer one or more servers for centralized authentication and identity management."

On 09/14/2011 06:59 AM, James A. Peltier wrote: > Yes, I did notice that, just wondered why. It seems more prone to breakage > (creating multiple symlinks vs one) There are a couple of reasons. I wont go into all, but the 2 that stick out the most for me are: 1) symlinking a step deeper means we can have more finer grained control over the content exported from the / and the / level, specially when it involved shared content ( Extras as one functional example, addons and contribs as another - but non impacted here ) 2) This is the more important one : with /6/ and 6.X/ being real physical locations there is still the door open that allows /6/ to become the CR repo. Entirely, across the OS/ and Updates/+ CR/ whereas 6.X/cr/ then becomes local to what is representative of a next-release content repo ( in relation to the point release its injected into ). This becomes even more relevant when you factor in 'CR/ content will not move to vault.c.o when the .X content does'. Furthermore, this is an important issue when we consider that the CR repo is opt-in, having a /6/ stream that is always updated and always just-usable irrespective of what 6.X one installs on their machines is always going to be a good goal to achieve, imho. Impact on how we do things, how we store stuff, stage content, get it into the mirrors, export to users and yum clients : massive. Ofcourse, the only experience that needs to be protected is the yum-client interface, and can we achieve this refactor without impacting yum-client interfaces ? I dont know. What I do know, is that very very few external mirrors have the capacity to handle something of this nature. Solve'able problems no doubt. There are also site-specific benefits like being able to add and track local repo's without needing to add in hackery over the centos mirror rsync exported content within a / or .X/ tree. And for people who run multiple machines, or need to have different production environments this tends to be quite a big deal. >From the user perspective, it should not make a difference as to where the symlinks are setup to -> from.

[CentOS] Cons of disabling *.i386 and *.i686 in a 64bit Distribution
Can anybody give me a reason why this would be a bad idea. So the premise for this question is that I setup an exclude=*.i368,*.i686 in my yum.conf. While doing a yum update I come across missing package dependencies for instance mkinitrd for the i386 package. I noticed there is already one for x86_64. I realized during the kickstart install that some of these *.i386 got installed before I could enable the exclude in the yum.conf. So the questions I pose is... why are some of these *.i386 packages getting installed on a 64bit distro? is there any harm is removing them all? I guess I could spin up a virtual and try, but wanted to see what the census already knows about this matter as well.

I could not see any issues with it. As you probably know i386 packages will work on an x86_64 install, and there are some packages written for i386 that you can't get for x86_64.

CentOS-5.7 is based on the upstream release EL 5.7 and includes packages from all variants including Server and Client. All upstream repositories have been combined into one, to make it easier for end users to work with. This is just an announcement email, not the release notes. The Release Notes for CentOS-5.7 can be found on-line at : http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.7 and everyone is encouraged to look through them once. Also worth browsing through are the CentOS FAQs at http://wiki.centos.org/FAQ +++ Upgrading from CentOS-5.6 ( or CentOS-5.0/5.1/5.2/5.3/5.4/5.5): If you are already running CentOS-5.6 or an older CentOS-5 distro, all you need to do is update your machine via yum by running : 'yum update' Running 'yum list updates' before doing the update is recommended, so you can get a list of packages that are going to be updated. To check you are indeed on CentOS-5.7, run : 'rpm -q centos-release' and that should return: 'centos-release-5-7.el5.centos.1' If you are running CentOS-5.6 and have the CR repo enabled, a simple 'yum update' will still move your machine to 5.7. But since the CR repo already contained all the 5.7 updates, there will only be a handful of rpms that need to be installed for the 5.6 to 5.7 upgrade. If you are not running the CR repo, we highly encourage everyone to install and run this repository on their machines. More details on the CR repo can be found online at http://wiki.centos.org/AdditionalResources/Repositories/CR +++ Downloading CentOS-5.7 for new installs: When possible, consider using torrents to run the downloads. Not only does it help the community and keeps mirrors from running up high bandwidth bills, in most cases you will find its also the fastest means to download the distro. There are currently over a hundred people seeding CentOS-5 and it's possible to get upto 100mbps downloads via these torrents. - -- Via BitTorrent : CD: http://mirror.centos.org/centos/5.7/isos/i386/CentOS-5.7-i386-bin-1to8.torrent http://mirror.centos.org/centos/5.7/isos/x86_64/CentOS-5.7-x86_64-bin-1to8.torrent DVD: http://mirror.centos.org/centos/5.7/isos/i386/CentOS-5.7-i386-bin-DVD.torrent http://mirror.centos.org/centos/5.7/isos/x86_64/CentOS-5.7-x86_64-bin-DVD.torrent md5sum's for these torrent files: 8e29e525f45c4a7b3a963cc01ec3459a CentOS-5.7-i386-bin-1to8.torrent 32c9e0826b50d6be44823523be403c7f CentOS-5.7-x86_64-bin-1to8.torrent 795d6c11b5ef8907653360af52b9f317 CentOS-5.7-i386-bin-DVD.torrent 04c563f2c838bf6b255fcc5fcc18cf66 CentOS-5.7-x86_64-bin-DVD.torrent sha1sum's for these torrent files: 8a945ba89b03328480fde20eaa0b638ceb7f4509 CentOS-5.7-i386-bin-1to8.torrent b1a18ba25e77543c4df9078dfafba990fbd58601 CentOS-5.7-x86_64-bin-1to8.torrent d3c4ed0d14fe1873bbcee931224e5e8819f779dc CentOS-5.7-i386-bin-DVD.torrent 302850dd4f9a8198b303f872c83a5a16ec1c40c2 CentOS-5.7-x86_64-bin-DVD.torrent While torrent files will do their own content checks, and only the right torrent will register and download from torrent.centos.org - its very important for your own security that an md5/sha1sum check is done on the .torrent file itself, and ensure that only the torrent.centos.org tracker is being used.

[CentOS] Yum update to 5.7 unexpected results

I installed ntp and initscripts individually and yum continued to report 404 on the rest of the updates on both machines. One machine i386, the other x86_64. I did a 'yum clean all' followed by 'yum update' and it installed centos-release and centos-release-notes but not nss, nss-tools, ghostscript or nspr updates.

I'm already only installing the base and @core packages during a kickstart, so I might as well try and keep it all clean from the get-go, but noticed that some packages do creep in that are not needed seeing there is an x86_64 equivalent. =) The packages that are only available via i386 are the ones I'll have to keep indeed.

Re: [CentOS] TIP for broken ARIN whois
Just a point on the curve but... ARIN has made a deliberate decision to move emphasis over to their RESTful Web Interface, Whois-RWS. Part of the reason is performance and part of the reason is for granularity of the data available. They really REALLY want people to make that move although they will continue to support the old whois for a lot of the basic stuff. https://www.arin.net/resources/whoisrws/index.html I believe one of the things I heard at last years NANOG / ARIN conference here in Atlanta was that they would no longer be providing certain information such as reverse DNS servers in the old whois because that's now in a different database or some such. On another closed security forum on which I participate someone was having problems getting at Abuse POC information. There a parameter for that as well but they prefer using the Whois-RWS interface and API instead. I think we'll be hearing more of that as time goes on.

[CentOS] Run commands automatically when bringing up/down network interfaces?
I'm looking for a capability similar to Debian/Ubuntu's pre/post up/down network commands capability. The problem: we've got a colo in which hosts talk directly to the hosting provider's router (through a bridging firewall) and hence our hosts MAC addresses are cached by the router. We should be able to solve this by pinging the router directly when bringing up the interface, rather than waiting (a day) for the router's ARP cache to expire. Yes, this means we're switching which hosts respond to a specific IP address, yes, we have to do this periodically. An alternative would be to remap the MAC address, though pinging the router seems cleaner, and the MAC remap would /still/ have to run when the interface is brought up/down. -- Dr. Ed Morbius Chief Scientist / Philologist / Robot Wrangler / Powerplant Operator Krell Power Systems Unlimited ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] TIP for broken ARIN whois
Another alternative, if you're simply looking for ASN/CIDR information, is to use the routeviews project. host -t txt 51.51.51.51.asn.routeviews.org ... returns the ASN and CIDR block of the IP in question. Note that as usual, this is reversed dotted quad, so if your original IP is 1.2.3.4, you're querying 4.3.2.1.asn.routeviews.org More information on the routeviews project: http://www.routeviews.org/ If you want information on the ASN, you can still query WHOIS. Or you can hit the CIDR Report: http://www.cidr-report.org Example: $ host www.cidr-report.org www.cidr-report.org has address 203.133.248.2 $ host -t txt 2.248.133.203.asn.routeviews.org 2.248.133.203.asn.routeviews.org descriptive text "4608" "203.133.248.0" "24" karsten@zharben:~$ host -t txt 51.51.51.51.asn.routeviews.org 51.51.51.51.asn.routeviews.org descriptive text "4294967295" "0" "0" karsten@zharben:~$ host www.cidr-report.org www.cidr-report.org has address 203.133.248.2 karsten@zharben:~$ host -t text 2.248.133.103.asn.routeviews.org host: invalid type: text karsten@zharben:~$ host -t txt 2.248.133.103.asn.routeviews.org Host 2.248.133.103.asn.routeviews.org not found: 3(NXDOMAIN) karsten@zharben:~$ host -t txt 2.248.133.203.asn.routeviews.org 2.248.133.203.asn.routeviews.org descriptive text "4608" "203.133.248.0" "24" karsten@zharben:~$ whois n 4608 No whois server is known for this kind of object. karsten@zharben:~$ whois n!4608 bash: !4608: event not found karsten@zharben:~$ whois AS4608 % [whois.apnic.net node-5] % Whois data copyright termshttp://www.apnic.net/db/dbcopyright.html as-block: AS4608 - AS4864 descr:APNIC ASN block remarks: These AS numbers are further assigned by APNIC remarks: to APNIC members and end-users in the APNIC region admin-c: HM20-AP tech-c: HM20-AP mnt-by: APNIC-HM mnt-lower:APNIC-HM changed: hm-chan...@apnic.net 20020926 changed: hm-chan...@apnic.net 20030207 changed: hm-chan...@apnic.net 20050309 source: APNIC aut-num:AS4608 as-name:APNIC-AP descr: Asia Pacific Network Information Centre descr: Regional Internet Registry for the Asia-Pacific Region descr: 6 Cordelia Street descr: PO Box 3646 descr: South Brisbane, QLD 4101 descr: Australia country:AU admin-c:HM20-AP tech-c: NO4-AP notify: n...@apnic.net mnt-by: MAINT-APNIC-AP mnt-irt:IRT-APNIC-AP changed:hm-chan...@apnic.net changed:hm-chan...@apnic.net 20110309 changed:hm-chan...@apnic.net 20110815 source: APNIC role: APNIC Hostmaster address:6 Cordelia Street address:South Brisbane address:QLD 4101 country:AU phone: +61 7 3858 3100 fax-no: +61 7 3858 3199 e-mail: helpd...@apnic.net admin-c:AMS11-AP tech-c: AH256-AP nic-hdl:HM20-AP remarks:Administrator for APNIC notify: n...@apnic.net mnt-by: MAINT-APNIC-AP changed:hm-chan...@apnic.net 1998 changed:db...@apnic.net 19990702 changed:hm-chan...@apnic.net 20020211 changed:hm-chan...@apnic.net 20070612 changed:hm-chan...@apnic.net 20100217 changed:hm-chan...@apnic.net 20101217 changed:hm-chan...@apnic.net 20110815 source: APNIC person: APNIC Network Operations address:6 Cordelia Street address:South Brisbane address:QLD 4101 country:AU phone: +61 7 3858 3100 fax-no: +61 7 3858 3199 e-mail: net...@apnic.net nic-hdl:NO4-AP remarks:Administrator for APNIC Network Operations notify: net...@apnic.net mnt-by: MAINT-APNIC-AP changed:net...@apnic.net 1998 changed:hostmas...@apnic.net 20020211 changed:hm-chan...@apnic.net 20081205 changed:hm-chan...@apnic.net 20101217 source: APNIC $ whois AS4608 % [whois.apnic.net node-1] % Whois data copyright termshttp://www.apnic.net/db/dbcopyright.html as-block: AS4608 - AS4864 descr:APNIC ASN block remarks: These AS numbers are further assigned by APNIC remarks: to APNIC members and end-users in the APNIC region admin-c: HM20-AP tech-c: HM20-AP mnt-by: APNIC-HM mnt-lower:APNIC-HM changed: hm-chan...@apnic.net 20020926 changed: hm-chan...@apnic.net 20030207 changed: hm-chan...@apnic.net 20050309 source: APNIC On Sat, Sep 10, 2011 at 7:26 AM, Always Learning wrote: > This works for me on Centos 5.6.

Re: [CentOS] Run commands automatically when bringing up/down network interfaces?
OK. The next question becomes: how do we ensure that this happens for each defined IP, and that the ping is issued from a given IP address (routing/ etc.). What we're hoping to accomplish is for the colo switch to get the correct ARP address for each defined IP address on the host. In some cases, we'll have multiple NICs on the same subnet, in others, IP aliases on the same NIC.

Have a look at arping(8) and it's -U flag in particular rather than ping.
Also read 'man ifup'. That refers you to
/usr/share/doc/initscripts*/sysconfig.txt
which talks about the ifup-post script. Looking at the end of ifup-post,
we see the following:
if [ -x /sbin/ifup-local ]; then
/sbin/ifup-local ${DEVICE}
fi
So it's probably the case that you could create a /sbin/ifup-local
that, based on the device name, may arping the gateway.
I was looking at my RHEL6 laptop when I was writing this, but C6 is almost
certainly the same.

It seems that the primary.xml.gz file is somehow corrupted, but I've
already tried a "yum clean all" and a "rm -rf /var/cache/yum/*" without
success.
Apart from being at CentOS 5.6 and all having this problem, the boxes
have very few in common:
- 2 physical machine running 5.6 32-bit, one in my office, the other in
a datacenter
- 1 physical machine running 5.6 64-bit in another datacenter
- 2 KVM VPS running 5.6 32-bit in a third datacenter
- 1 Xen VPS running 5.6 64-bit in a fourth datacenter
There was a thread on the forum some months ago which mentioned this
same problem, but the original poster didn't find a solution (or if he
did, he didn't share it with the forum). Any suggestion is appreciated,
I cannot reinstall those boxes with 6.0 for at least 4/5 months.

make sure that there isn't any yum/rpm processes running...
ps aux|grep yum
ps aux|grep rpm
Once you've determined they aren't running, try...
yum clean metadata
yum clean dbcache
(those should be executed when you execute 'yum clean all' but maybe it ain't
gettin' done)
and then
yum update

The issue originates from the fact that the new CR repo has no sqlite metadata store, its xml only. And your machine was trying to get the sqlite files - hitting a valid 404, since those files do not exist. The actual issue is that rather than yum seeing a new repomd.xml in the repodata/ dir, downloading that and knowing that there is no sqlite db available, it retained the repomd.xml you already had ( from the prev 5.6/cr repo ). So I dont think the issue really is that you hit a 404, but why was yum looking for a repo metadata file that does not exist, the new repomd.xml clearly states that those files do not exist. Do you have something interesting setup for caching, timeouts etc in yum ? or, are you perhaps behind a proxy that still served up an old ( stale ? ) repomd.xml for the same url ? - KB ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Error in updating to 5.7
I also encountered a similar problem. "yum clean all" did not resolve it, but *not* installing the CR prior to the update repo did. I think the problem is that my update script was still installing centos-release-cr-5.6 (the URL was hardwired, as I couldn't think of a simple way to get the correct one). The script also installs the CR repo prior to the update and uninstalls it afterwards, since I wasn't sure if the CR repo would continue to exist when 5.7 was released (the CR wiki page [1] says "The repository will go-away once the packages are released via the regular process"). However, it seems that the CR repo is still there, and a centos-release-5.7 upgrade is available through it. Is it safe/advisable to leave the CR repo installed in-perpetuity? Or do I need to remove it after using it, if I want to prevent potential yum-upgrade errors if it does go away?

I put my customer on WebERP (http://www.weberp.com) He has used in the last 15 years... Real World Accounting (since bought by Great Plains - bought by MS) Peachtree Accounting BusinessWorks Cougar Mountain Demand I handled all of the data import/transitions from one to the next with the exception of Cougar Mountain => Demand because the woman who sold him on that was a previous technical support manager for Cougar Mountain. Anyway, the one he has liked the most is the one that he didn't pay for - WebERP Before anyone gets the idea that this is all wine and roses, there are some shortcomings with WebERP, largely due to the fact that they seem to do continual releases and never really have a 'stable' version (regardless of what they say). That meant to me that I had to fix about 10-15 different things and needless to say I have no intentions of upgrading at this point (now 2+ years down the road). I have more gripes about WebERP but they are not entirely significant (with the exception that to 'extend' the featureset of WebERP, I used Ruby on Rails instead of PHP because I can do significantly better code in one quarter of the time). WebApps are clearly the future - it's hard to justify specialized server/client applications (installation, limited choice of clients, maintenance, licensing) and it seems that the future will offer 2 choices... SAAS or run your own. My own take on it... 'plain html' accounting is just fine. This company has 4 retail stores, each with a warehouse and relatively low skilled computer users entering orders. Print jobs are downloaded (or e-mailed PDF files). This is NOT a POS system (then again, neither is Quickbooks). To keep the PHP reasonably secure, it requires HTTPS and access authorization is done by LDAP authz so if you don't have a username and password on his system, you can't get the login screen. Of course the server is kept up to date. Ajax/jquery definitely ups the quality of appearance, sometimes ups the quality of the UI but definitely slows down the application and is just another demonstration of all that glitters isn't necessarily gold. As for Paul's expressed notions... It would take a fairly massive amount of man hours to produce a fully functional dual entry accounting package for widespread business use. Before you decide on an environment, you would probably want to commit to test driven development and MVC which almost invites the use of a framework (Cake/Django/RoR). Personally I am biased towards RoR but starting a large scale project in ruby, php or python without using one of the frameworks at this point would be a really poor choice. There are a number of PHP based accounting systems out there which you could probably fork but why? They all missed the boat somewhere, somehow.

If they want to use it, let them. Ajax is not a programming language, its a technique of implementing the client (browser) side of your applications in JavaScript, which is the programming language. ever use gmail or google documents? thats ajax. its interactive within the USER BROWSER without requiring round trips to the web server for every little operation such as summing up the checks entered in a form as they are being entered. An Ajax accounting program could be interactive like Quickbooks is, as opposed to fill in a static form and hit submit for every little action. And, if you've never used a SQL join, you don't know the first thing about *relational* databases, you've been using SQL as though it was a simple flat table ISAM, DBase-style circa 1983.

SAAS or run your own. That is the way I see things. Web runs anywhere.

'plain html' accounting is just fine. Mine are a bit more than 'plain'. I use CSS. However accounting is basically entering or capturing the data; then doing basic tasks like orders, invoices, statements etc. Add some complicated things like credit control and specific discount structures for individual customers. Branch-out in to name, address and other contract details, add the mailing list facility. Add stock control, automatic re-ordering etc. The best bits that make the directors happy is when they can sit in front of the screen and see the sales figures and trends. Everything summarised on a single page with more detailed analyse with a simple click. Think Gmagic, or perhaps Imagic, may be able to plot on a HTML screen. Have headings in a language file, so international customisation becomes easier. Add an access control system allowing users to access different modules and menus. OK one can't (yet?) plug-in a bar code reader to a web application but an interface box can transmit the data using TCP. > To keep the PHP reasonably secure, it requires HTTPS and > access authorization is done by LDAP authz so if you don't have a > username and password on his system, you can't get the login screen.

Security with HTTPS and non-standard ports not 443, 8000, 8080 etc. Currently use static IPs to prevent unauthorised access. > As for Paul's expressed notions...

I think the essential thing is sheer inspirational brain work carefully thinking about everything before stating to code. Get the structure and the objectives correct and the rest is a piece of cake.

Simple to write, harder to ensure everything integrates well. Probably 3 to 4 months part-time. Easy and intuitive to use and delivering what the users want plus scope for customisation. -- With best regards, Paul.

Its a programming language is my humble opinion. One has to 'code' in it. It has a defined syntax and it has a rather large and complex overhead. By the way, I also think BASH is a programming language. > ever use gmail or google documents? thats ajax. its interactive > within the USER BROWSER without requiring round trips to the web server > for every little operation such as summing up the checks entered in a > form as they are being entered.

There is no reason to use joins and views IF the database is carefully planned. Joins and views are another overhead. Rule Number 01 in programming is Keep It Simple. Index-sequential is another database access method that came along. Very useful. Access random is another. Data is actually 'flat'. It can not be anything else. However additional retrieval by non-primary key is usually desirable. Traversing chains of linked records is another method too. I've done several domestic and international contracts writing applications using relational databases. Are you more of a Sys.Op than a computer programmer / systems analyst / systems programmer / database designer / systems designer ? When SQL first came out, I think it was an IBM thing, I never liked the syntax. Years later I'm using it effectively and very productively. > but, whatever. its your project, have at it. Thank you.

[CentOS] trouble booting install CD on old machine
Hi all, I'm having a bit of an issue booting the full 5.7 install CD on an older machine. I downloaded the ISOs earlier today, checked the sha1sums, and burned the CDs with no reported errors. But when I try to boot, the isolinux banner comes up quickly, but then instead of the boot prompt, I get a completely blank screen. After 30-60 seconds, I get a message in purple, the exact wording I don't recall, but something like "can't boot, please restart". Many years ago I put CentOS 4 on this machine, so I know it can boot CD media, and earlier today I booted an older UBCD, so I know that it can successfully boot from CD at the present time. (I didn't have time to test the CD I burned in another box; I will do that next time I have the CD.) What other options do I have for getting 5.7 on this box? I have a few ideas: --do some troubleshooting with the 5.7 CD. I don't really know how to go about this, and there's no guarantee it'll end up with being able to boot in the end. --perhaps an older CentOS 5 ISO will work better? Testing this will be fairly quick but is not sure to work. --remove the system disk, put it into another system that is known to boot the 5.7 CD, install there, then put the disk back. This could be somewhat time consuming (the machine is in a rack, and the system drive is buried in the chassis, not hot-swappable), but is pretty sure to work. --try to boot from USB. As I said, it's an old box, so I'm not sure it supports booting over USB media. There were no "boot from USB" options in the BIOS; I could try to flash the firmware, but that seems excessive for this sort of issue. Other thoughts/suggestions? Any ideas why I'd be seeing this particular boot behavior? It's not something I've seen before; either booting fails before even reaching isolinux, or the kernel panics on finding some exotic and/or broken piece of hardware. --keith -- kkel...@wombat.san-francisco.ca.us pgpSNLNkerbPp.pgp Description: PGP signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
