Probelm with some smtp MTAs
by James B. Byrne 20 Feb '07

20 Feb '07

I am getting large numbers of these types of messages in my maillog files: somehost.hotmail.com [65.54.246.97] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA on both of our external machines beginning on the same date. These hosts sit on different netblocks and on both machines the sendmail.cf files date from Jan 09, 2007. The last successfull connection from any hotmail acocunt was on Jan 15 at 13:17:29. The first failure was recorded on Jan 15 at 18:36:46. Does anybody have any idea what is going on? We are now getting reports that hotmail users are getting a delayed transmission warning and then a failure message. Is this a sender's issue or our local configuration issue? ANY help regarding this matter would be most appreciated. If you feel that sendmail related items should not be discussed on the list then please contact me privately. Thanks, Jim -- James B.

CHINA: Donation Scheme and Quality Community Development
by Richard Ford 20 Feb '07

20 Feb '07

G'Day All, We have been supporting linux as a side business for a while (because we use that skill set in our own value chain internally) and we are now going to start targeting the wider local Chinese market and not just the foreign companies and joint ventures. As such we expect to see tremendous growth in this market segment this year due to the quickly dwindling support of local support outlets due to the poor local skill sets and fundamental understanding of computing and Linux practices. But this growth may be short lived as the segment itself disappears (Linux and anything not Microsoft off the shelf) as evidenced by less and less exhibitors and attendees at Linux World here over the past 4 years. I am trying to figure out a way to change this. Of course we can donate money back to the project itself - but does anyone have any idea on how to help the local Chinese get better as a form of donation too? Maybe offering free support services? Point is, people should be paying IT professionals money to do UML and process design as they do in the west (Accenture, CA, IBM, et al) and not to play with technology day in day out. However in China, IT is more dumbed down and is akin to "Computing Services", backup, servers, hosting, windows/linux/cisco/et al is what comes to mind. While this is all fine and dandy it is hardly IT and it is a very price erosive market (China and India combined) and seems to be destroying the local demand for real IT and everyones chance to start more off-shoring operations here in competition with India. The concept of technology being a support service to a greater operational goal and process (value chain) is quickly shoved to the side as people here consider IT to be a "cost" and focus on the "lego" aspect of it - computing services, mutton dressed up as lamb. And Linux is not seen as a fertile bed to develop, create and explore, it is often just used to plunder and get something for free...cheap, cheap, cheap...... I know that I can't change a country on my own, however, the atrophy in Open Source Community development and IT service demand is really sad here. I saw a post before from a chap who said words to the effect of: > Meanwhile, if there are many companies engage in > same product, they will have price competition with each other. That > will make companies could not survive after that. So, we hope your > company could authorize us as a exclusive distributor to sale and > market your product to share our resources and Chinese sales network. And it is any wonder that open source cooperation here is failing as people fail to understand the "knowledge economy" that is central to open source? And IT is not expanding as it continues to be percieved as purely bits and bytes and not also opportunity cost and risk. So I on behalf of the Beijing GNU/Linux Users Group ask for some advice, pointers and tips for how in my own small way I can get some change happening here before all creative technological thinking and successful open source development becomes even more extinct. And before real IT has a chance to take off and operate in harmony with all the business analysts and accountants as opposed to with just the motherboard and disk driver retailers at the various tech depots. :-( Don't get me wrong, there is Linux use here - but nothing new and nothing is ever thrown back into the community - just take and abuse. :-( Cheers, Richard Ford. centos.candishosting.com.cn www.beijinglug.org

RPMS's -- Standalone or From Sources?
by Benjamin Sher 20 Feb '07

20 Feb '07

Dear friends: [Using the Centos 4.4 DVD) I will spend the next few days reading the documentation for Centos/RedHat. But meanwhile, I would like, while reading it, to listen to my favorite radio programs which require RealPlayer. So, my question is simply: should I download the RealPlayer RPM from www.real.com or should I download it from an rpm repository source? While I am at, what about other programs such as Acrobat Reader, Java, etc.? Thank you so much. Benjamin

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.
