problem starting X11 on centos 6
by Jerry Geis 22 Jul '11

22 Jul '11

Hi All, I had an issue. Manually installing Centos 6 everything worked X11 came up with nvidia binary drivers. Cool. However, I am working on a kickstart install for Centos 6 and that was not working. When I started X it would hang. no mouse no keyboard. however , remote ssh was available and worked. Thinking I had some serious bug in nvidia binary was my thought - but I kept looking. I saw this error: (EE) config/hal: couldn't initialise context: unknown error (null) in the X log file. I continued to look and sure enough hald was installed but not running. I did service haldaemon stop and it said FAILED as expected, then service haldaemon start and it started up. Curious.... chkconfig --list | grep hal reports haldaemon 0:off 1:off 2:off 3:off 4:off 5:off 6:off So thats the reason of course, it was not set to start. Question is why???? certainly I can put in my kickstart post script to change chkconfig but why is it not set to start???? Thanks for any insite. Jerry

Experience with Centos running off usb-stick(s)
by Dennis Jacobfeuerborn 22 Jul '11

22 Jul '11

Hi, I'm trying to build a redundant duo of firewalls/routers/gateways and I'm thinking about not putting any disks in them and instead using a usb-stick raid-1 as storage. Has anyone any experience with this? Since the machines will be running pretty much only iptables, conntrackd and keepalived there is not going to be a lot of disk activity going on and the plan is to do all the logging on a remote machine which should reduce the write activity on the sticks to almost zero during normal operation. I've already created a fairly minimal kickstart for such an installation but I'm wondering if there are any opinions out there on whether this is a feasible approach or if there are any gotchas I'm not aware of. Regards, Dennis

Using shell variables inside the ftp client
by James B. Byrne 22 Jul '11

22 Jul '11

I have a script that opens an ftp connection to a non-*nix system. I desire to change directories on the host system using a shell variable to set the cd directory. However, I cannot seem to discover how this is done. I have tried this: TARGET=ftp-pickup ftp . . . cd $TARGET This gives the following error: 550 Failed to change directory. I am using shell variables (put $TEMP_TXFR_FILE $OUTPUT_FILE) elsewhere in this ftp session as arguments to get and put statements and I have no problems. Is there some reason why I cannot use shell variables as arguments to the cd command? I am aware the $ is used to invoke .netrc macros but I have none defined. In fact I was somewhat surprised, albeit pleasantly, when the ftp client accepted shell variables as arguments in the get and put statements. Is there a way to dynamically define the target of a cd command inside an ftp session? -- *** E-Mail is NOT a SECURE channel *** James B.

CentOS artwork
by James Szinger 22 Jul '11

22 Jul '11

Thanks to the CentOS artwork team. I've found the CentOS artwork to be nicely done and the CentOS 6 release is up to your usual high standards. I really appreciate the desktop background that stays in the background, and doesn't demand my attention. Jim

Memory Usage in Top and System Monitor‏

That was the point of my earlier posts asking why swap when there is plenty of free memory. Correct me if I am wrong, but I believe behavior is unused files in /dev/shm use swap space? I want to make it so it does not do that since it slows the system down and since there is plenty of available free memory.

NetApp DataFabric Manager/Sybase/SQLAnywhere on CentOS?
by Matt Garman 21 Jul '11

21 Jul '11

Hello, Has anyone out there successfully installed NetApp's "DataFabric Manager" (DFM) on CentOS? If so, what version of DFM, CentOS, and what architecture? I am trying to install DFM 4.0.2, and have tried on both CentOS 4.8 i386 and CentOS 5.5 x86_64. I have edited my /etc/redhat-release file to be equal to RHEL's, as the DFM installer immediately aborts if that isn't right. However, I still have errors during the install: Enter your NetApp DataFabric Manager license key [?,q]: <entered my key> Beginning the installation ... Preparing... ########################################### [100%] 1:NTAPdfm ########################################### [100%] Installing scripts in /etc/init.d directory.

Anyone been down this road? So far NetApp is stonewalling me on CentOS support. Thanks, Matt

Re: [CentOS] Memory Usage in Top and System Monitor‏

I think I found my problem. I did not realize using /dev/shm as a ramdisk will create swap space. Is there a way to prevent the ramdisk from swapping to disk?
