Default printer environment variable
by Kanwar Ranbir Sandhu 27 Apr '07

27 Apr '07

Hello All, I'm trying to get the iSeries Access for Linux client (IBM 5250 emulator) working on a CentOS 4.4 system. The client is mostly working - it connects to the remote AS/400, the custom keymap I created is recognized, etc. The only problem is printing to a local printer. The docs for the client state that it reads the default printer environment variable to figure out which printer to print to on the local side. What's the default printer environment variable? $PRINTER? I'm lost on this one since I've never had to set it before. I know that I can create a ~/.lpoptions file and put the default printer in there, but that's not going to work with this IBM 5250 emulator. Any tips/help appreciated.

network config files in centos 5 changing
by Jerry Geis 27 Apr '07

27 Apr '07

What is happening in centos 5 with network config files??? I have a machine with 2 network cards. ifcfg-eth1 keeps changing to DHCP. All my static setup is gone. Why is it doing this? How can I stop it? I run "netconfig -d eth1" and re-setup my static information. I reboot and now I am back to DHCP. I have a gigabyte motherboard, nvidia chipset. forcedeth driver. eth0 is e1000.

recompile kernel 2.6.20.7 (so I get updated forcedeth driver)
by Jerry Geis 27 Apr '07

27 Apr '07

I installed 2.6.20.7 copied /boot/config{something} to .config make oldconfig make oldconfig make menuconfig - turned on drivers -> Sata -> nvidia make bzImage make modules make modules_install make install rebooted. Seems like the issue I had with forcedeth (nvidia) bad MAC address is gone. However, the iptables gives errors. Where in the menu tree do I enable what iptables needs??? I have looked around in there and did not see it. Thanks, (I know I'm not compatible now... :) Jerry

kernel 2.6.21 on centos 5
by Jerry Geis 27 Apr '07

27 Apr '07

I have a computer that I needed to put 2.6.21 on. Everything is working fine after recompile except when iptables is starting up it errors with iptables-restore: line 23 failed. This is the normal centos 5 iptables. nothing special. What might I be missing in the new kernel that I get this error? Thanks, The file is below.

[CentOS 5] - SAMBA+LDAP
by Gabriel Stein 27 Apr '07

27 Apr '07

Hi! I´m have some problems deploying OPENLDAP+SAMBA+PAM+NSSWITCH. When I restart the server with those services, the DBUS service crash. And when I try disable DBUS service on system start Avahi crashs too. Someone here have this problem? There´s a BUG on CentOS 5? Maybe PAM not talking with LDAP on startup? I can send some logfile and my system-auth setup. Thanks for your attention. -- /\ Gabriel Stein gabrielfstein(a)gmail.com MSN: gabrielstein(a)hotmail.com Administrador de Redes - Network Administrador Linux User #223750 51-92796310 Porto Alegre - RS - Brasil

Re: ralink rt61 in centos 5 [solved]
by Olaf Mueller 26 Apr '07

26 Apr '07

Hello, Maybe someone will run into the same problem, so here is how it works for me. I could not get work my wlan card (ralink rt61) with the driver from rt2x00.serialmonkey.com under CentOS 5 (2.6.18-8.1.1.el5). All drivers (beta and daily cvs) from this site freezes my system. So I get the driver from the Ralink support at http://www.ralinktech.com/ralink/Home/Support/Linux.html (RT2501PCI/mPCI/CB(RT2561/RT2661)). With this driver, my wlan card works very well (WPA2, AES). CentOS 5 is great. regards Olaf

Xen guest and samba
by Rick Barnes 26 Apr '07

26 Apr '07

Hello, I am new to this list, but having been using CentOS for sometime. I recently installed CentOS 5 on a test server to check out Xen. The installation was smooth had so far I have everything working except I cannot get samba to join our AD domain from the xen guest, using para-virtualization, I setup. I am out of ideas, and cannot find anyone having similar problems. I have tested my config files on the server itself (Dom0) and it joins fine. But on the guest it will not join. kinit works and I do get a ticket from kerberos. But when I try to join I get: # net ads join -U administrator administrator's password: Using short domain name -- ICN Failed to set servicePrincipalNames. Please ensure that the DNS domain of this server matches the AD domain, Or rejoin with using Domain Admin credentials. Disabled account for 'XEN01' in realm 'ICN.LOCAL' In messages, I have: Apr 25 10:36:02 xen01 winbindd[29659]: [2007/04/25 10:36:02, 0] libads/kerberos.c:ads_kinit_password(208) Apr 25 10:36:02 xen01 winbindd[29659]: kerberos_kinit_password XEN01$(a)ICN.LOCAL failed: Clients credentials have been revoked Apr 25 10:36:34 xen01 pcscd: winscard.c:219:SCardConnect() Reader E-Gate 0 0 Not Found The hosts, resolv.conf, smb.conf and krb5.conf files are the same between the guest and Dom0 and are using the same version of samba. Selinux has been disabled in order to make sure it was not interfering. Has anyone had this issue or successfully able to join to a domain from a guest? Thanks, Rick

linux dd on CentOS 5 x86
by Drew Weaver 26 Apr '07

26 Apr '07

Howdy, I had to use a driver disk today to install CentOS 5 on a Poweredge 1900 /w a 3ware 9650SE controller card. The only gotcha I noticed is that for some reason CentOS 5 will not read driver disk files off of a thumbdrive (usb key) when it is being emulated as auto, hard disk, or floppy disk. (it saw the thumb drive as SDA in all instances) however when I plugged in a USB floppy drive (the poweredge 1900 is sans floppy controller) it still saw the drive as SDA and it read the files off of the USB floppy disk. My question, I suppose is what is the difference between a floppy emulated SDA and a USB floppy SDA? Thanks, -Drew
