Hello, Anyone know how to get Acrobat 9 running* on Centos 4.7?

looking for alternative to SME & Clark Connect
by Rudi Ahlers 17 Apr '09

17 Apr '09

Hi all, I'm looking for a (preferably free) alternative to SME / Clark Connect. I basically need the following: - firewall - nat - VPN - bandwidth limiting / monitoring - email (SMTP / POP3 / IMAP) & groupware - file & printer sharing - RAID support - if possible fail-over / high availability support. I need to support about 15 - 30 (some part time) students, so I would like to keep the costs low. If it's free, so much better. SME works for most of the stuff, but it still runs on CentOS 4, and I'd prefer to use 5. Any recommendations? -- Kind Regards Rudi Ahlers

Re: [CentOS] kernel update doesn't update grub.conf
by Devin Reade 17 Apr '09

17 Apr '09

[I saw this thread in the mailing list archives, but wasn't subscribed at the time, so sorry it's not a proper follow-up.] The symptoms you describe could be a side effect of being previously hit by <http://bugs.centos.org/view.php?id=2914> and <https://bugzilla.redhat.com/show_bug.cgi?id=447841>. Those bug items describe workarounds. After you get mkinitrd upgraded to that in 5.3 the problem should go away, although you may have to manually fix up the results of the bad kernel install.

by Ed Donahue 17 Apr '09

17 Apr '09

Anyone ever come across a linux server host key changing with out a reboot, sshd restart, change in negotiating (SSHv1, SSHv2), and different DNS name or IP address? I have a server on RHEL4.4 that changed its host key. Red Hat Enterprise Linux ES release 4 (Nahant Update 4) openssh-server-3.9p1-8.RHEL4.15 2.6.9-42.ELsmp uptime 944 days Started getting the eavesdropping message from a login that is supposed to login w/o a password. And always did before today.

CUPS oddity
by Niki Kovacs 17 Apr '09

17 Apr '09

Hi, I've been setting up a few printer servers with CUPS. Our public libraries here all run 100% Linux (CentOS 5), so what I do is simply install the printer on one of the machines (with a static IP) and then configure CUPS so it can act as a printer server for Linux clients. It took me some time to figure this out, and I remember pulling my hair out for a few sunny afternoons, but I eventually got it working. One thing kept me stuck for days, until I finally found the answer on debian-administration.org. My server machine has an IP of 192.168.1.252/255.255.255.0. There's a Brother laser printer attached to it. The CUPS configuration file is edited so machines on the 192.168.1.* network can use it, and I can also access the CUPS web interface from anywhere. But here's what puzzles me. In the default cupsd.conf configuration file the 'Listen' directive looks like this: # Only listen for connections from the local machine. Listen localhost:631 Listen /var/run/cups/cups.sock Here's the oddity: I *have* to specifically add the machine's IP, like this: Listen localhost:631 Listen 192.168.1.252 Listen /var/run/cups/cups.sock If I don't add this, machines on the network are unable to connect to the server. Can anybody explain this strange behaviour to me? Cheers, Niki

CentOS 4 dkms-ndiswrapper
by Agile Aspect 17 Apr '09

17 Apr '09

Hi - I'm trying to get wireless running on CentOS 4.7 on a dual core laptop (latitude-e4500) for an employee. I'm having trouble with building dkms-ndiswraper-1.54-1.el4.rf - enclosed are the errors messages. The kernel was rebuilt to disable CONFIG_4KSTACKS. The errors prior to rebuilding the kernel are identical to the errors after rebuilding the kernel and rebooting - minus the error regarding the CONFIG_4KSTACKS. Basically I just typed make in the directory. I'm using dkms this time - I've never used it before. I'm under the impression that all I had to do was type 'make' in the directory in the ndiswrapper directory. Any help would be greatly appreciated! -- Agile make -C /home/praveen/rpmbuild/BUILD/kernel-2.6.9/linux-2.6.9 M=/usr/src/ndiswra pper-1.54-1.el4.rf make[1]: Entering directory `/home/praveen/rpmbuild/BUILD/kernel-2.6.9/linux-2.6 .9' MKEXPORT /usr/src/ndiswrapper-1.54-1.el4.rf/crt_exports.h CC [M] /usr/src/ndiswrapper-1.54-1.el4.rf/crt.o In file included from /usr/src/ndiswrapper-1.54-1.el4.rf/crt.c:16: /usr/src/ndiswrapper-1.54-1.el4.rf/ntoskernel.h:289:1: warning: "for_each_possib le_cpu" redefined In file included from include/linux/sched.h:15, from include/linux/module.h:10, from /usr/src/ndiswrapper-1.54-1.el4.rf/ntoskernel.h:22, from /usr/src/ndiswrapper-1.54-1.el4.rf/crt.c:16: include/linux/cpumask.h:374:1: warning: this is the location of the previous def inition In file included from /usr/src/ndiswrapper-1.54-1.el4.rf/crt.c:16: /usr/src/ndiswrapper-1.54-1.el4.rf/ntoskernel.h:649: error: field `lock' has inc omplete type /usr/src/ndiswrapper-1.54-1.el4.rf/ntoskernel.h: In function `raise_irql': /usr/src/ndiswrapper-1.54-1.el4.rf/ntoskernel.h:686: warning: implicit declarati on of function `mutex_lock' /usr/src/ndiswrapper-1.54-1.el4.rf/ntoskernel.h: In function `lower_irql': /usr/src/ndiswrapper-1.54-1.el4.rf/ntoskernel.h:708: warning: implicit declaration of function `mutex_unlock'make[2]: *** [/usr/src/ndiswrapper-1.54-1.el4.rf/crt.o] Error 1 make[1]: *** [_module_/usr/src/ndiswrapper-1.54-1.el4.rf] Error 2 make[1]: Leaving directory `/home/praveen/rpmbuild/BUILD/kernel-2.6.9/linux-2.6.9' make: *** [modules] Error 2 -- "We are drowning in information and starving for knowledge." -- Rutherford D.

You just cannot put the system drive on an extended partition, it has to be a primary partition. If that is the first non-Linux partition Windows will name it C, anyway, as it just ignores partition types it doesn't know. But, as I said, the letter doesn't matter.

No need for it. You just change grub.conf. If you want to use a second disk because of drive numbering: no, you don't need to do that. If you want to do it for other reasons, like space: go ahead!

I've never seen this problem at all - running AMD 64x2 7750, 4Gb memory with GEForce 7200gs card, nvidia driver nvidia-x11-drv-173.08-1.beta.el5.rf.x86_64 (from rpmforge - duh). I've used a 19" CRT, 17" 1280x1024 flat panel and, currently, 22" 1680x1050 flat panel (Emprex - cheap, but works great). I tried the L&G nvidia driver last year some time, but I decided I'd rather have the rpmforge working dkms driver than the L&G, even though it's a beta driver. When I upgraded to 5.3, that was the first time the driver was actually rebuilt for the kernel since 5.0. HTH mhr
