CentOS-2 update 5
by John Newbigin 18 Aug '04

18 Aug '04

CentOS-2 update 5 is about to be released. As of update 5, Netscape 4.8 will be removed from the distribution. The currently shipped version of Netscape 4.8 has security flaws and should not be used. Users of CentOS-2 should uninstall the Netscape packages and switch to using mozilla. For more information see RHSA-2004:429-01 Also, in order to easily identify packages which have been modified for CentOS-2, the release suffix .c2.release will be appended to the existing release. All packages which currently are missing this suffix will be reissued with the new suffix. The suffix release will always start at 1 and be incremented if a package needs to be reissues with only centos changes. When the original release is increased, the centos release will start again at 1. This is part of a new automated procedure which should result in reproducible modifications which will speed up the release of errata for modified packages and cut down on errors in the modification process.

ssh problems
by scty Library 13 Aug '04

13 Aug '04

Here's another one for ya, I can ssh into my server from workstationB but when I try to ssh into workstationB from my server I get this error message. @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is 55:2e:6a:d8:08:26:7f:cd:f4:1d:36:8f:cf:85:3d:1a. Please contact your system administrator. Add correct host key in /home/diadicic/.ssh/known_hosts to get rid of this message. Offending key in /home/diadicic/.ssh/known_hosts:2 RSA host key for 172.16.12.200 has changed and you have requested strict checking. Host key verification failed. Now it looks like I have to learn about rsa keys and ssh. A point in the right direction would be appreciated. Thank all. __________________________________ Do you Yahoo!? Yahoo!

centos31 anaconda bug with lvm lvcreate?
by sophana 13 Aug '04

13 Aug '04

Hi I just tried to install centos3.1 from the 3cd. I removed all existing partitions and made a custom partitionning: a /boot partition /dev/hda1 and a lvm physical volume for the rest: /dev/hda2 in the lvm volume group I placed all other partitions including root (/) The anaconda crashed because of an error in lvcreate for the root partition. Is there a problem with that? I did reboot and restarted with then same config and it is now installing. I have saved the debug info on a floppy if anyone interested. Thanks Sophana

Re: migration center
by Rick Graves 13 Aug '04

13 Aug '04

John, > I started a web page to collect my ideas > http://uranus.it.swin.edu.au/~jn/linux/centos-2/migration.htm I looked at the page collecting your ideas. That is a good start, and a good looking web page. Your wizard idea is fancier than what I had in mind. I was thinking of a table listing the starting points and in the left column and the sensible options in the right column. Then step by step instructions for each supported migration path. (I can imagine writing step by step instructions by actually doing it and taking notes as I go.) I agree that we do not have to rush it. On the other hand, I do not know what the schedule for the new web site will be. As for the migration center content (plain text type content), I suggest we move at our own pace, and when we are ready, either put the content in the existing site or in the new site, whichever is available. When cAos moves to the new site, much if the text will get copied from the old site and pasted into the new site anyway. Since I do not know anything about the schedule for the new site, I can imagine that it could take more time than doing a useful migration center. I simply suggest that we do not let any potential problems in doing a whole new web site delay putting out migration information that people could be using right now. > Each procedure could have a forum where people can contribute feedback, like they do with the php manual. This would be best. > Another thing I might have a play with is a family tree. That might help people see the differences between versions. That is another good suggestion. It could go in the FAQ explaining the difference between cAos and CentOS. Rick

John, I did not hear back from you right away. Maybe doing all the combinations is too big a job for one person. It might work if we split them up. I could do these two: RedHat 9 -> reinstall CentOS-3.1 RedHat 9 -> live update to CentOS-3.1 I am volunteering for these because I already have RedHat 9 and CentOS-3.1 CD's. The only rub is on Saturday I go on vacation, and at the end of August I will be back to where I have my computer junk. I could do those two in early September. Any other volunteers for any of the other combinations? My offer to work it all into the web site still stands.

Re: more about messing around with iptables
by Rick Graves 12 Aug '04

12 Aug '04

Hey scty Library, > I am messing around with iptables, trying to learn how it works so that I can build my self a router/firewall and mabey a VPN. Oops! I forgot about that. The LinWiz iptables wizards cannot help you, a router/firewall/VPN application is too complicated for them. If you do not care about reinventing the wheel, then proceed with your learning experience. If you just want a router/firewall/VPN, look at Smoothwall. A mountain of effort and expertise has been put into that dedicated firewall distribution, and I suspect there is NO WAY anything you could do on your own could come close. But if your purpose is to have a learning experience, then you are on the right track.

Hey scty Library, I forget your name. I do not have an answer for your question exactly. However, I think I have a solution to the overall problem, and it is here: http://www.lowth.com/LinWiz/1.09/ I use the wizards to create my iptables files. I have a couple of basic files that I use, and then I tweek the appropriate one after copying it to a new install. For people who want a solution fast, the two wizards are great. I hope this helps.

suggestions for CentOS
by dan1 12 Aug '04

12 Aug '04

Hi to all, I have some suggestions to make about the CentOS 3. I think that this would be great to include many questions we have on this mailing list into the FAQs of the centOS site. They are so poor, that we feel like nothing is happening for this centos 3, and in fact this seems to be a very good distribution.. too sad.. Probably that finding a way to access the mailing list archive through a search for non-subscribers would help a lot new users, and motivate them. I also had contact with the switch.ch mirror site of Switzerland (1Gbit/s), and they would be ready to mirror your distribution if it would become more known. So there should not be any bandwidth problems, and I wish that CentOS 3 will become known from the others. It's so strange, nobody knows about it.. A better documentation on your site would perhaps also help a bit, and motivate people to use it. Especially making a bigger difference on the site between cAos and CentOS 3 would be great (the way the site is designed). I also regret to not find any information on google groups about that. It's so sad.. Isn't it possible to post your e-mails to google groups (open a new channel for centos, etc..) ? In all cases, thank you for all, I'm very pleased to use CentOS 3 and try to make it known by others ! Hope this will help.. Daniel
