Hello
I happen to have two network interfaces on my new, up-to-date, CentOS 6.2, named eth0 and virbr0 (3 of them if I include the lo interface).
However the system APIs like getaddrinfo() only return the address for the virbr0 interface (which was created by the CentOS installation), when I would like to have them both.
Even if I give the configured eth0 address explicitly to getnameinfo(), it can not perform the reverse lookup to my hostname, and returns a string with the same numeric IP address given as argument. I also can not get the list of samba name aliases for my host name.
I can happily ping my host from a different computer on the eth0 network, so the nmb service binds on eth0 and works as expected.
I have installed and configured smb, nmb and winbind services, and I have added 'wins' to /etc/nsswitch.conf, so my hosts line there looks like: hosts: files wins mdns4_minimal [NOTFOUND=return] dns
Is there something I should do for wins name service to return all IP addresses ?
Are there some similar settings that I need to do in order to get the reverse lookup to work ?
For reference here are my system information and application output, as follows.
Here are my interfaces: [adrian@adrian projects]$ ifconfig eth0 Link encap:Ethernet HWaddr 00:1C:C0:DA:63:75 inet addr:10.0.0.154 Bcast:10.255.255.255 Mask:255.0.0.0 inet6 addr: fe80::21c:c0ff:feda:6375/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1222539 errors:0 dropped:0 overruns:0 frame:0 TX packets:708669 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1491421614 (1.3 GiB) TX bytes:136206085 (129.8 MiB) Interrupt:20 Memory:d0600000-d0620000

And here is how my applications behave: [adrian@adrian projects]$ python Python 2.6.6 (r266:84292, Dec 7 2011, 20:48:22) [GCC 4.4.6 20110731 (Red Hat 4.4.6-3)] on linux2 Type "help", "copyright", "credits" or "license" for more information.

[adrian@adrian projects]$
As you can see there are no name aliases returned, and there is only one IP address given for my host name.
You can see my samba name aliases here: [adrian@adrian projects]$ nmblookup -A -T 10.0.0.154 Looking up status of 10.0.0.154 ADRIAN <00> - B <ACTIVE> ADRIAN <03> - B <ACTIVE> ADRIAN <20> - B <ACTIVE> ..__MSBROWSE__. <01> - <GROUP> B <ACTIVE> TERMINATORUL <00> - B <ACTIVE> TERMINATORUL <03> - B <ACTIVE> TERMINATORUL <20> - B <ACTIVE> TIMOTHY <00> - B <ACTIVE> TIMOTHY <03> - B <ACTIVE> TIMOTHY <20> - B <ACTIVE> TOUGHY <00> - B <ACTIVE> TOUGHY <03> - B <ACTIVE> TOUGHY <20> - B <ACTIVE> WORKGROUP <1d> - B <ACTIVE> WORKGROUP <1e> - <GROUP> B <ACTIVE> WORKGROUP <00> - <GROUP> B <ACTIVE>
MAC Address = 00-00-00-00-00-00
(namely adrian, terminatorul, timothy, toughy). Trying to resolve my hostname to an IP address with nmblookup also returns just one of the IP addresses:
[adrian@adrian projects]$ nmblookup adrian querying adrian on 192.168.122.255 192.168.122.1 adrian<00> [adrian@adrian projects]$
For some times I'm loosing graphical applications usage as pirut and system-config-users, Yum auto update is not working too but I can update with command lin yum update
Versions instlalled pirut-1.3.28-19.el5.centos.noarch.rpm system-config-users-1.2.51-7.el5.rpm
Do somebody have an idea for a solution

Run both commands from terminal and see what error is being reported.

Thak's to care, For pirut I get: Unable to import modules. Maybe yoy'r not running undr X? But I'm under X with KDE
For system-config-users I get: Trace back (most recent call last): File "/usr/share/system-config-users/system-config-users.py",linne 25, in? import libuser ImportError: no module name libuser
I checked and libsepol-1.15.2-3.el5 is there also /user/lib/libuser and .so , .so.1, .so.1.1.6 etc are there
If I type at command line import libuser I get the same reaction as running "system-config-users" the program seem to turn round but no execution and tnhen stop But if I look in /etc/libuser.conf I see a line as: # The default (/usr/lib*/libuser) is actually correct Do I have to think that the modules should be in /user/lib/libuser/ instead of /usr/lib/
What should be my next move? --- Michel Donais

Hi. Both the issue and the message are similar to some errors I receive if
I forget to change to CentOS default Python before using yum & Co. You probably already checked for this but anyway: Do you have more than one Python intallation, or did you compile Python from source, or used a package that installed a Non-CentOS-default Python version? Regards, Jesus

Where should be default python Packages are only installed by yum update usually CR but I also have some updates been made from epel but can't remember wich
--- Michel Donais
Where should be default python
Hi Michel. Type python --version on the command prompt. CentOS 6.2 has Python 2.6.6, CentOS 5.6, 5.7, 5.8 have Python 2.4.3. Epel should not have installed a different python. Maybe you only need to reinstall the library so Python recognizes it???

Try "yum reinstall libuser", or "yum install libuser"
actual re-installed version is libuser.i386 0:0.54.7-2.1.el5_5.2
Hi Michel. Maybe something related to root / non-root? Or: Can you check your Python version? Can you enter into Pythons cli (just type python) and then type "import libuser"? If you don't get an error message, I don't know. If you do, type "print (sys.path)", one of the paths should be something like "/usr/lib/python2.4/site-packages/". After exiting the python cli, you can check if your libusermodule.so can be found under this path or one of python's sys.path? Regards, Jesus

Hi Michel. This is only to print a sys variable; you don't need to do anything there. So your default python finds the libuser library, the error you saw before with import libuser is not coming from this python, at least as root. Does it make sense to remove pirut and re-install it? I don't use it, I have absolutely no idea which consequences it may have removing and reinstalling pirut for software that was already installed under pirut.

It's already been done, uninstall and re-install pirut without success. The version removed end the re-installed one were at the same level
For Centos-5.8 I've a test machine both are at the same level of update. If I do >>>print (sys.path) on the production machine, I get
import sys print (sys.path)
['', '/usr/lib/python24.zip', '/usr/lib/python2.4', '/usr/lib/python2.4/plat-linux2', '/usr/lib/python2.4/lib-tk', '/usr/lib/python2.4/lib-dynload', '/usr/lib/python2.4/site-packages']
And on the test machine I get
import sys print (sys.path)
['', '/usr/lib/python24.zip', '/usr/lib/python2.4', '/usr/lib/python2.4/plat-linux2', '/usr/lib/python2.4/lib-tk', '/usr/lib/python2.4/lib-dynload', '/usr/lib/python2.4/site-packages', '/usr/lib/python2.4/site-packages/Numeric', '/usr/lib/python2.4/site-packages/gtk-2.0']
If I refer at Larry Martell message, he pointed that the problem was with sys.path
If I look in ?usr/lib/python2.4/site-packages/ numeric in there on the test machine but absent on the production one
I tried to re-install python-numeric.i386 0:23.7-2.2.2.el5_6.1 and nothig change; numeric is still not there
On these facts, can somebody point me a solution?
