vertify which software for missing dependenies
by Edward Martinez 16 Nov '11

16 Nov '11

Hi, I'm trying to install RPM package Adobe Reader on Centos 6. I did a rpm -test -ivh on the package and it says it needs dependencies (many) Is a there a command to verify which exact packages it requires so I wont be installing software blindly. missing dependencies: error: Failed dependencies: libatk-1.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libc.so.6 is needed by AdobeReader_enu-9.4.2-1.i486 libc.so.6(GLIBC_2.0) is needed by AdobeReader_enu-9.4.2-1.i486 libc.so.6(GLIBC_2.1) is needed by AdobeReader_enu-9.4.2-1.i486 libc.so.6(GLIBC_2.1.3) is needed by AdobeReader_enu-9.4.2-1.i486 libc.so.6(GLIBC_2.2) is needed by AdobeReader_enu-9.4.2-1.i486 libc.so.6(GLIBC_2.2.4) is needed by AdobeReader_enu-9.4.2-1.i486 libc.so.6(GLIBC_2.3) is needed by AdobeReader_enu-9.4.2-1.i486 libc.so.6(GLIBC_2.3.2) is needed by AdobeReader_enu-9.4.2-1.i486 libdl.so.2 is needed by AdobeReader_enu-9.4.2-1.i486 libdl.so.2(GLIBC_2.0) is needed by AdobeReader_enu-9.4.2-1.i486 libdl.so.2(GLIBC_2.1) is needed by AdobeReader_enu-9.4.2-1.i486 libfontconfig.so.1 is needed by AdobeReader_enu-9.4.2-1.i486 libfreetype.so.6 is needed by AdobeReader_enu-9.4.2-1.i486 libgcc_s.so.1 is needed by AdobeReader_enu-9.4.2-1.i486 libgcc_s.so.1(GCC_3.0) is needed by AdobeReader_enu-9.4.2-1.i486 libgcc_s.so.1(GLIBC_2.0) is needed by AdobeReader_enu-9.4.2-1.i486 libgdk_pixbuf-2.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libgdk_pixbuf_xlib-2.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libgdk-x11-2.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libglib-2.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libGL.so.1 is needed by AdobeReader_enu-9.4.2-1.i486 libGLU.so.1 is needed by AdobeReader_enu-9.4.2-1.i486 libgmodule-2.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libgobject-2.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libgthread-2.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libgtk-x11-2.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libidn.so.11 is needed by AdobeReader_enu-9.4.2-1.i486 libm.so.6 is needed by AdobeReader_enu-9.4.2-1.i486 libm.so.6(GLIBC_2.0) is needed by AdobeReader_enu-9.4.2-1.i486 libm.so.6(GLIBC_2.1) is needed by AdobeReader_enu-9.4.2-1.i486 libpango-1.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libpangoft2-1.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libpangox-1.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libpangoxft-1.0.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libpthread.so.0 is needed by AdobeReader_enu-9.4.2-1.i486 libpthread.so.0(GLIBC_2.0) is needed by AdobeReader_enu-9.4.2-1.i486 libpthread.so.0(GLIBC_2.1) is needed by AdobeReader_enu-9.4.2-1.i486 libpthread.so.0(GLIBC_2.1.1) is needed by AdobeReader_enu-9.4.2-1.i486 libpthread.so.0(GLIBC_2.2) is needed by AdobeReader_enu-9.4.2-1.i486 libpthread.so.0(GLIBC_2.2.3) is needed by AdobeReader_enu-9.4.2-1.i486 libpthread.so.0(GLIBC_2.3.2) is needed by AdobeReader_enu-9.4.2-1.i486 libresolv.so.2 is needed by AdobeReader_enu-9.4.2-1.i486 libresolv.so.2(GLIBC_2.2) is needed by AdobeReader_enu-9.4.2-1.i486 librt.so.1 is needed by AdobeReader_enu-9.4.2-1.i486 librt.so.1(GLIBC_2.2) is needed by AdobeReader_enu-9.4.2-1.i486 libstdc++.so.6 is needed by AdobeReader_enu-9.4.2-1.i486 libstdc++.so.6(CXXABI_1.3) is needed by AdobeReader_enu-9.4.2-1.i486 libstdc++.so.6(CXXABI_1.3.1) is needed by AdobeReader_enu-9.4.2-1.i486 libstdc++.so.6(GLIBCXX_3.4) is needed by AdobeReader_enu-9.4.2-1.i486 libstdc++.so.6(GLIBCXX_3.4.5) is needed by AdobeReader_enu-9.4.2-1.i486 libX11.so.6 is needed by AdobeReader_enu-9.4.2-1.i486 libXext.so.6 is needed by AdobeReader_enu-9.4.2-1.i486 libxml2.so.2 is needed by AdobeReader_enu-9.4.2-1.i486 libXt.so.6 is needed by AdobeReader_enu-9.4.2-1.i486 libz.so.1 is needed by AdobeReader_enu-9.4.2-1.i486

lm_sensors on Sun (x86) Hardware
by Alan McKay 16 Nov '11

16 Nov '11

Hey folks, I'm running RHEL 5.3 on 6 boxes - and on every one of them sensors-detect finds nothing. 5 of them are Sun fire 2250 machines, and 1 is Sunfire 4170. Googling and searching this list does not seem to find anything. When I log into the Sun hardware management interface (web interface) I see that it of course is correctly detecting various temperatures of things. But for some reason Linux is not. Does anyone here have experience in this area and can tell me how to fix this? thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

clustering
by Alan McKay 16 Nov '11

16 Nov '11

Hey folks, I just went through the archives trying to find some info on this but did not come up with much other than it seems there are a few experts here on the list. I have no experience with clustering and have just taken over a Stem Cell Research Lab that has a Grid Engine cluster. I have not yet dug into the details of Grid Engine (only been here a week now) but am just trying to get up to speed on clustering in general. I was just looking at Red Hat's site and they have this HPC thing http://www.redhat.com/promo/mrg/ but damned if I can find any actual details on it there - that data sheet they link to is just a bunch of marketing gobble-de-gook as far as I can make sense of it anyway. Quick question : what are Red Hat using to do that, and can CentOS do the same thing? How hard is it to configure? How does it compare to Grid Engine? I have to say I'm a bit hesitant about Grid Engine because of the whole Oracle takeover. I just don't trust Oracle. Basically I'd like to get up to speed really quickly on different clustering technologies, and maybe even set up a CentOS (or Scientific) based cluster in a sandbox to play with. I guess - looking for reading to get up to speed on clustering, and wondering what my options are with CentOS, RHEL and Scientific. thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

pgadmin3 missing dependencies
by Alan McKay 16 Nov '11

16 Nov '11

I searched the list archives and I found one answer to this which suggested I should install the PG yum repos. I don't like that answer for reasons which follow. I'm running Centos 6.0 freshly installed, and I've decided that with this box I'm sticking as much as possible to just the CentOS repos that go with that release. I figure in particular I do not need any PG features above what are offered in release 8.4 that comes from the CentOS repos, so I don't really want to install PG repos. But first of all I do not even see pgadmin3 in the CentOS repos anywhere. Am I correct that in order to get this tool I need to get it from the PG repo? It seems odd to me that CentOS would not have it but stranger things have happened. So I pull down the pgadmin3 RPM manually, and try to do a manual install only to find that a number of RPMs are missing and required. I guess at this point I could just install the repo for PG to yum it all, but I'd like to know what RPMs are required and I am unable to figure that out. I figured out at least that I need libxslt, but cannot figure out from the below output what other RPMs are needed and where I get them. libxslt I got from 6.0 yum repos.

"Overlay" Filesystem Mounts?
by Tim Nelson 16 Nov '11

16 Nov '11

Greetings- Is it possible to mount multiple block devices (or network devices over NFS/CIFS) such that the contents of the mounts appear in one location? For example, lets say I have these shares available: \\server1\volume1\ \\server1\volume2\ \\server1\volume3\ All three contain a directory called data, with different subdirectories. Typically, these would be mounted like so: mount \\server1\volume1\ /mnt/s1v1 mount \\server1\volume2\ /mnt/s1v2 mount \\server1\volume3\ /mnt/s1v3 And, each would have a corresponding 'data' dir at those mounts: /mnt/s1v1/data /mnt/s1v2/data /mnt/s1v3/data However, it is possible to mount all of the shares to one location, such that there is one 'data' dir, with the combined contents of each of the three shares? So, all shares are mounted at /mnt/s1, and the contents of the multiple data dirs appears in one single data dir? The only time I've seen such functionality is within the XBMC media center application. It allows you to mount multiple network shares, but shows them all in one location as a sort of 'overlay' view. Duplicate directories are shown have their contents merged, but remain intact on the actual shares/filesystem. Does any of this make sense? Is it possible with CentOS (pref. 6) ? --Tim

Hasn't this discussion drifted from the initial topic? I'm sure the price of tablets, of phone service, etc., are interesting to some, but PULEEZZE, look at the topic and ask "is the message contributing to the understanding of changes at RedHat confounding CentOS" David

Centos6 and samba and nmblookup
by david 15 Nov '11

15 Nov '11

Folks I've installed Centos6 and Samba. I noticed that the program "nmblookup" and a few other Samba related programs, documented in the RHEL6 guide, are not included in Centos6. A search using YUM also did not find "nmblookup", using the repositories: base, centosplus, contrib, cr, epel, extras, updates, virtualbox Has its functionality been moved elsewhere, or should I try to find something wrong in my environment? Thanks David Kurn

bond of bonds
by Paras pradhan 15 Nov '11

15 Nov '11

Hi, I am trying to use Link-aggregation with redundancy between switches that doesnot support SMLT in switches. I have 4 network ports. First two are connected to a switch and LACP/LAG is enabled. Third and Fourth ports connect to another switch with another LAG group. I was thinking create two mode 4 bonds and bond those bonds to mode 1 (Active/Passive) bond. But it seems this is not supported yet in kernel (?). How do you guys handle this kind of situation. (And yes without using SMLT between switches). Thanks Paras.

Redhat vs centos vs ubuntu
by Bob Hoffman 15 Nov '11

15 Nov '11

This is a continuation of the thread about redhat vs centos and the thought of moving from centos due to redhats new business model. Forgive the length, but I had to share. I went ahead and downloaded the 5 year supported version of ubuntu server. You think centos/redhat is a bit tough or not polished? One day with ubuntu server and you will look at centos install and setup as a god! Where do I begin? 1- you download the iso, burn a cd. But guess what? It is only a small boot setup (about 600mb). The install actually sets up your eth port and then SLOWLY downloads a base set of packages. Then when you are done with your drive set up, you get to pick a package. Then it downloads and installs, asking you a few questions as it does. Then it upgrades itself. About 40 minutes due to the downloads for me... 2- uses a really lame 1980 DOS version of a text installer. It does not and will not use a basic vid driver install which means your setting up of lvms and such during the install is really fun. 3- I don't know about having a server being forced to connect to the internet before you can even begin to secure it up. But the only way to really install it is to do that. Wait til you see the insecure firewall setup if gave me too.. 4- I picked the virtual host package, as the machine will hold guest OS's (presumably ubuntu). 5- booted up fine. 6- uses upstart and init, mixed up a bit. Upstart, BY DESIGN AND ACCORDING TO DOCUMENTATION is new and still being built so they do not want to put any documentation out on it yet. This makes chkconfig and things like that useless. Hence, if you want to know what is running, set to run, etc, you need to dig in multiple folders and read the scripts. There is no other way. What a horror. 7- The install, of the virtual host, added libvirt. It did not however install things like virt-install or any other virt software. Infact, no guest installation tools were added, though things like virsh were installed. Sigh. 8- The firewall and network do not have the scripts folder. You have to build your own firewall file and add scripts to make it over ride the stock one via the eth you want to use it for....wtf? 9- here is the firewall, for a virtual host, that should not have anything but port 22 open as far as the initial install should (at least in my opinion).....Ubuntu starts with this.... (remember, ubuntu forces you to be online to install and this is how it protects your server) I was not blocked on a single port going from my desktop to my server via my router. ALL PORTS were accessible. This is out of the box. Shell 22 was open from all my computers. Not listed in the firewall as open. You can see it is quite different than the centos stock and I think ubuntu is a 'run away' install. There is no bridge set up in the network interface files either. There is no bridge set up. The firewall is looking at virbr0 but there is no such configuration I could find in the etc folder, anywhere. Very odd. # Generated by iptables-save v1.4.4 on Mon Nov 7 23:35:47 2011 *nat :PREROUTING ACCEPT [84:12492] :POSTROUTING ACCEPT [9:626] :OUTPUT ACCEPT [9:626] -A POSTROUTING -s 192.168.122.0/24 ! -d 192.168.122.0/24 -p tcp -j MASQUERADE --to-ports 1024-65535 -A POSTROUTING -s 192.168.122.0/24 ! -d 192.168.122.0/24 -p udp -j MASQUERADE --to-ports 1024-65535 -A POSTROUTING -s 192.168.122.0/24 ! -d 192.168.122.0/24 -j MASQUERADE COMMIT # Completed on Mon Nov 7 23:35:47 2011 # Generated by iptables-save v1.4.4 on Mon Nov 7 23:35:47 2011 *filter :INPUT ACCEPT [3701:295955] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [793:1276008] -A INPUT -i virbr0 -p udp -m udp --dport 53 -j ACCEPT -A INPUT -i virbr0 -p tcp -m tcp --dport 53 -j ACCEPT -A INPUT -i virbr0 -p udp -m udp --dport 67 -j ACCEPT -A INPUT -i virbr0 -p tcp -m tcp --dport 67 -j ACCEPT -A FORWARD -d 192.168.122.0/24 -o virbr0 -m state --state RELATED,ESTABLISHED -j ACCEPT -A FORWARD -s 192.168.122.0/24 -i virbr0 -j ACCEPT -A FORWARD -i virbr0 -o virbr0 -j ACCEPT -A FORWARD -o virbr0 -j REJECT --reject-with icmp-port-unreachable -A FORWARD -i virbr0 -j REJECT --reject-with icmp-port-unreachable COMMIT # Completed on Mon Nov 7 23:35:47 2011 In closing, it is down to suse or back to centos and just pray redhat turns around. Maybe scientific linux. Ubuntu is not ready for prime time and a HUGE step backwards. It is not cutting edge and very insecure. So maybe centos, even if a year or two behind, is way better than ubuntu will ever be. I took a shot at paid support. You have to send them a contact mail. I did. After 3 days sent them another. 2 days later, no response from that one either. down to suse or back to centos. One good thing about ubuntu was the bug redhat has for the ati onboard video is not an issue making no errors on boot and no long hang time that centos was causing me.
