Uninstalling GAG Boot Manager -- Problem Solved!
by Benjamin Sher 20 Feb '07

20 Feb '07

Dear friends: Problem Solved! I had to donwload a new copy of GAG, install a new copy on a floppy, then reboot, switch to diskette in the Bios and only then does the GAG install/uninstall menu show up. Clicked on Uninstall and GAG not only uninstalled itself from the hard drive but also restored the old MBR. Now Centos boots up correctly. Thank God. Benjamin

Uninstalling GAG Boot Manager
by Benjamin Sher 20 Feb '07

20 Feb '07

Dear friends: New to Centos, DVD version 4.4. Fabulous distro, rich in features, applications, very stable and robust. My first install failed to boot up (after rebooting, switching in Bios from CD/DVD to hard drive. This was probably because I chose to install the Grub boot loader in MBR. I got the error message: GRUB, Stage 2 Loading... But it never loaded up. Nothing happened. So, I did a fresh install of Centos. This time I chose the first partition on hda (hda1). Rebooted, switched from CD/DVD to hard drive. When the computer started booting up, it immediately brought up the GAG Boot Manager, which I had used earlier to dual boot Linux and Windows. The floppy drive was empty and the Bios was definitely turned to hard drive. I had earlier saved my GAG settings both to the floppy and the hard drive. That explains why it's still on my hard drive. At any rate, I used GAG to add Centos to the operating systems. I clicked on Centos and this booted up Centos successfully (after first seeing the lovely Centso blue boot-up screen. I no longer need GAG and would like very much to get rid of it and boot up Centos normally. How do I do that, please? Here is the URL for GAG: http://gag.sourceforge.net/ I downloaded GAG originally in Windows and installed it on a floppy, then saved the settings to the floppy and then to the hard drive. I might add that GAG worked fine earlier. The problem is that I can't seem to bring up the GAG screen that allows you to install or uninstall it. I click on R for Restore but I never see the install/uninstall screen. I'd very much appreciate your help. Thank you. Benjamin P. S. One funny thing: I am sending this letter from Kmail in Centos. I know for a fact that I am supposed to use login authentication to send mail. I had configured my email program, including Kmail, many times in the past and it always worked fine. But this time, the only way I could send my mail was to NOT use login or any kind of authentication. Does this make sense? Yet, the mail failed to go out with authentication but was sent successfully WITHOUT authentication. Is this some sort of bug or is this normal? I'd appreciate your help. Thank you all so much.

Fwd: Fwd: [CentOS] HOW to enable traceroute with IPTABLES(SLOVED)
by Indunil Jayasooriya 20 Feb '07

20 Feb '07

Hi all, That issue is over now. I found why my ESTABLISHED,RELATED rule at the top of INPUT chain did not work for udp and icmp. The reason was I have included the protocol as tcp as below iptables -A INPUT -i eth0 -p tcp -m state --state ESTABLISHED,RELATED -j ACCEPT I removed -p tcp from above rule. Now it works for all protocols. Thanks for your support. ---------- Forwarded message ---------- From: Robert Spangler <lazydog(a)zoominternet.net> Date: Feb 20, 2007 2:45 AM Subject: Re: Fwd: [CentOS] HOW to enable traceroute with IPTABLES To: Indunil Jayasooriya <indunil75(a)gmail.com> On Mon February 19 2007 00:00, you wrote: > I have included ESTABLISHED,RELATED at the top of your INPUT chain as > below > > #Allow established,related trafffic to come back > #(for OUTPUT traffic to come back) > iptables -A INPUT -i eth0 -d 192.168.101.60 -p tcp -m state --state > ESTABLISHED,RELATED -j ACCEPT > > But without an INPUT statament it does not work.

I have a couple of workstations that are perfect candidates for Linux at a client's location. The only think i am shaky on is getting CentOS 4.4 to integrate into the AD domain.

RE: [CentOS] Starting samba configuration

Swat is disabled by default under xinted. You'll need to go into /etc/xinetd.d/swat, comment out the line for disable=no, and add your subnet to the network line. Restart xinetd to reread everything and you should be good to go. Thanks!

OT rpmforge rpm is not putting Dag repo info in yum.conf
by Steve Campbell 19 Feb '07

19 Feb '07

I should change this to OT, as it's not really CentOS related. I had a post on the list last week asking how the rpmforge rpm was to be implemented in yum. Craig White was kind enough to list how his yum.conf is appended, I assume after he installed the rpm. Unfortunately, mine is not appended with these lines. I am running CentOS 3. I will add these lines manually, and probably remove the yum.repos.d folder. This could be related to the fact that this was an upgraded Tao machine, and I had to remove and reinstall the yum rpms as the centosplus repos were also not in the conf file, but the main repos for Centos were there. I just wanted to let people know that installing the rpmforge rpm doesn't seem to work all the time. It seems to think that I have a CentOS 4 version of yum, so it creates the extra repos folder, adds the mirrors and conf files under the repos folder and does not append the yum.conf with the repository info. I have probably done something improper along the Tao->Centos upgrade path, but I am not sure what. Thanks for all of the help. Steve Campbell campbell(a)cnpapers.com Charleston Newspapers
