Re: [K12OSN] Help? Programs not Running?



Jim,

Thanks for the tips.
Got one server ready to go. I will check on the failing one tomorrow afternoon and let you know of the results.

double check that the bridge device ltspbr0 actually exists (check lsmod - check ifconfig and /etc/sysconfig/network_scripts/ifcfg-* )
Double check that ip_forwarding is still OK

watch the dhcpd log with tail -f  while things are trying to connect and see if the server "sees" anything.

double check the firewall allows incoming dhcp requests.

HOWEVER: I'm assuming the clients are regular LTSP clients so they already get dhcp during their PXE boot phase - thus dhcp IS working.

run back through the /var/log/yum.log and see what was updated.

Not to Hijack the thread but I updated 02 of my servers - Scientific Linux 6 - yesterday afternoon and after that, clients no longer can authenticate and get a login screen. Also updated ssh-keys, verified the dhcp server, etc.
The only noticeable error message I see is that when the servers are coming up, the system says that either ltspbr0 is duplicated by dev or, it is garbage.
Eth1 however, initializes fine. Just no DHCP offers. I have uninstalled the ltsp-server, re-installed it and rebuilt the client with ltsp-build-client.
Something must have changed in a config file that I am missing it big time.
Google returned many unrelated things
If I cannot figure it out soon, it will be a long night tonight.

Hello everyone,

I need some help.  I was doing my standard update today to keep the system up to date and it blew up in my face.

Now after finally working all day and getting the users able to log back in.  They can log in, and run any apps that run via ltsp-local-apps, however any apps that run on the base system cause the user to get kicked out back to the login screen.

Pertinent system information:

[root shopltsp ~]# rpm -qa|grep ltsp
ltsp-release-5-9.el6.noarch
ltsp-server-5.4.5-20.el6.i686
ltspfs-1.1-7.el6.i686

[root shopltsp ~]# cat /etc/*release*
CentOS release 6.4 (Final)
LSB_VERSION=base-4.0-ia32:base-4.0-noarch:core-4.0-ia32:core-4.0-noarch:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-ia32:printing-4.0-noarch
cat: /etc/lsb-release.d: Is a directory
CentOS release 6.4 (Final)
CentOS release 6.4 (Final)
cpe:/o:centos:linux:6:GA


This is what I'm seeing in messages log:

[root shopltsp log]# tail messages

I've done some googling, but I've been unable to turn up anything that corrects the problem as of yet.

Thanks for any help!
