CentOS 3.4 to CentOS 4
by Jason 03 Apr '05

03 Apr '05

I have upgraded to CentOS 4 from 3.4. I am having trouble figuring out the mail changes. Under 3.4, Imap and POP were modules that xinetd controlled. Under 4.0, I have a choice of either Cyrus-Imapd or Dovecot. After googling all week, I was about to get my user account authenticated under Cyrus and the saslpasswd program, as well as dovecot. My problem is that they don't know where my mail is. I run postfix, and have mail delivered to /var/spool/mail/%u. I put this into Cyrus' mail directory but it still doesn't see anything. Dovecot always tries to chdir to the user's home directory, ignoring anything I put into dovecot.conf concerning mail locations. Any ideas? Thanks.

So, here is the problem. Lets say that Acme Widget has their mail hosted with Hostco. Acme Widget would rather not have mail.hostco.com in the mail headers for whatever reason. So, hostco doesn't setup a ptr record for it. This does not make Acme Widget or Hostco any more likely to be spammers, it just makes you more likely to drop their mail. Now, the other side of that... Foospam wants to send out 87 bazillion mail messages to everyone about fooagra. So, they set their mail server to helo with fooco.com and set the ptr record to be mail.fooco.com and they just danced right by all of this with very minimal effort. For that matter, you can use whatever ptr your ISP sets up for you. The whole accountablity thing is a fallacy. I can buy a domain right now for $8, put whatever I want in the whois info and just use that for the ptr record part, it could be a throwaway domain for all I care. At the end of the day, it bought the person reciving the spam nothing. Reverse DNS or not, you can see what IP the mail came from, you can tell who is the owner of that IP and they can find out what user has that IP. The problem is that most of them are simply unwilling to do so, they ignore mail to the abuse address or just give you a canned answer. My point is that relying on this only makes you more likely to drop legit mail and poses no problem to the spammers. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

It specifically states that there are alternatives (an address literal) RFC 2821 also says: There are two exceptions to the rule requiring FQDNs: - The domain name given in the EHLO command MUST BE either a primary host name (a domain name that resolves to an A RR) or, if the host has no name, an address literal as described in section 4.1.1.1. So, it seems to me that the RFC compliant way to do this is to use the literal address in the HELO Meaning that those who reject this are the non RFC compliant ones... -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

CentOS4 laptop touchpad erratic operation
by Collins Richey 02 Apr '05

02 Apr '05

I've just put up CentOS4 on my HP ze4630us laptop, and the installation produced only two problems of note, both related to X operations. 1. The installer refused to allow 1024x768 resoultion for the screen. After install, manually setting the resolution in xorg.conf was no problem. 2. Erratic touchpad operation. This unit has a synaptic touchpad. I've also noted similar problems on my previous Gentoo install (also 2.6 kernel and xorg). Never really resolved this. When scrolling across a screen in a browser panel where there are multiple links, the mouse will trigger click operations all on its own, so it's difficult to reach the link you want without inadvertently opening another link that you scroll past. In googling, I didn't have much luck finding a matching problem; nor did I have much luck earlier. Most of the problems reported seemed to be "touchpad unable to respond to clicks", i.e. the opposite of my problem. The installer generated the following mouse definition in xorg.conf: Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "IMPS/2" Option "Device" "/dev/input/mice" Option "ZAxisMapping" "4 5" Option "Emulate3Buttons" "yes" EndSection Has anyone else seen this type of problem with a touchpad, and does anyone have knowledge of a fix?

It's not a matter of difficult, nor does it provide any accountability. I can tell my mail server to helo whatever I want and make the ptr say whatever I want. It doesn't authenicate anything. Nor does someone running an SMTP server with a dynamic address prove anything about it being spam. The big problem that I have with it is that it completely ignores shared hosting.

Centos 4 & Cisco 350 MiniPCI Wireless
by Barry L. Kline 02 Apr '05

02 Apr '05

I have an IBM Thinkpad with this beastie in it. The card was immediately recognized and uses the airo driver. No matter what I do, I can't get it to successfully connect to my WAP. Sometimes it sees the access point (as evidenced by an iwlist wifi0 scan seeing the network) and sometimes I can actually get it to connect ( as evidenced by the iwlist command showing the WAP ID). Eventually the connection between the card and the AP simply dies. I'm not new to wireless and have had no problems manually configuring other wireless cards to work properly, so I have gone through most of the gyrations. Right now I've fallen back to an Orinoco silver. Google doesn't seem to be helpful in this endeavor (lots of hits but most having to do with the 2.4 kernel series) so my question is relatively simple: Before I waste an inordinate amonut of time trying to make this thing work I would like to know if anyone else has had success here? If so, could you tell me the firmware version of your card? Even if you can't I'd be delighted to hear that the fact that the kernel manages to turn on my wireless light isn't the kernel's way of teasing me. Thanks very much! BK

postfix tightening
by Craig White 02 Apr '05

I am used to sendmail and am using Postfix now and am uncertain of some features. I typically would comment out the line in sendmail.mc that went something like 'accept unresolvable domains' I tried using smtpd_sender_restrictions = reject_unverified_sender reject_unverified_smtp and this seems a bit too restrictive and got some bounces on legitimate senders so I'm thinking that this is perhaps a bit more apropos... smtpd_helo_restrictions = permit_mynetworks, reject_invalid_hostname does this make sense?

[CentOS] Lost all info in a file server because of LVM - HEEEELP ME, please

Hi, I'm totally desperated. I have this file server with a total of about 200 GB of my user's files. The server has "3 in 1" discs, using LVM. Somehow, i don't know why, the LVM info is gone and i cannot access my file system. I had in LVM: sda1 -> /boot sda2 -> / sda3 -> /home (where all the Samba shares resides). sda4 -> swap sdb sdc Tha machine now starts with a single partition ( / ) mounted on /dev/root From there i can manually mount under /mnt partitions "/boot", "/", but NOT "/home". Trying to mount /home, i always get the busy error. I cannot unmount the "/" on /dev/root, obviously. How can i (if possible) restore the LVM info ? I have a backup from Sunday, so, it's really not a life or death case, but nevertheless it is a real annoiance, and the server is already down for 24 hours :( Any help would be apreciated.

Odd Question... MAX Ram Disk Size
by Scott Heisler 31 Mar '05

31 Mar '05

Greetings, Before I get slammed, I've looked all over the internet for the answer to this (googled and more) and haven't been able to find what I'm looking for. Here's what I need. I have a server that I use to hold workstation images. I use a Linux boot CD combined with some scripts I wrote and some disk imaging software to allow me to image windows workstations. Anyway, when I roll out a new workstation Image, I may roll it out to 20 or 30 computers at once, all using the same image file (base build). I want to put that image file on a RAMDISK on my server. The image file is between 3 and 4 gig. I have 6 gig in the server, so plenty of memory. I modified GRUB to increase the size of my ram disk... First I started with a 200mb, that worked group, formatted, etc. Then I tried 1gig - everything looks like it works but when I mount it, it tells me the volume is not formatted or has invalid super blocks. Perhaps I'm exceeding the allowable built-in ramdisk limit, but I couldn't find any docs anywhere that would tell me what that limit was. Does anyone know of an alternative ramdisk product, that does not load at boot time, where I could do what I need (as described above)? Or does anyone know how I can get a 4-gig Ramdisk to work properly? I'm running the new CentOS 4 on the server. Thanks for any help. I did spend 2 days doing Internet research with no results, prior to posting here. Thanks. Scott

RE: [CentOS] Odd Question... MAX Ram Disk Size
by Scott Heisler 31 Mar '05

31 Mar '05

Thanks everyone for the great INFO... This was EXACTLY what I needed and had a very hard time finding out. The mount -t tmpfs -o size=1g none /ramdisk worked perfectly. I needed temporary ram space to use as disk space. Thanks! Just to explain further, the "images" are not ISO's... These are hard drive images, like GHOST files (only using a Linux free application).

OK. time to make some contribution (centos4/ppc)
by Pasi Pirhonen 31 Mar '05

31 Mar '05

Hi, Even now someone is actually installing (i see that from the ftp-server logs) the centos-4/ppc beta-version from announced place. You people have to stand up and _TELL_ me what kind of hardware _IS_ working, so we would know more than already know - 43p works. I can't believe that all those, who installs, does have 43p too? Please? Something, so if it's actually working on something else than already known 43p, we'd really like to hear about it. If it's not working, we'd still ike to hear about it as one can't fix anything not known to be broken. Someone something, so eventually there would be release? -- Pasi Pirhonen - upi(a)iki.fi - http://iki.fi/upi/

I thought I'd share this with you guys:- Been working/testing on the DEV release of SME7a3 based on CenTOS (on VMWARE), see contribs.org. Pretty neat I must say, most daemons (DNS, DCHP, SMB-PDC, LDAP, IMAP, POP, Web Admin) are preconfigured. I've got phpGroupware, WebERP, KnowledgeTree + other running on the same box (VMWARE).

CentOS as an internet gateway
by ryanag＠zoominternet.net 31 Mar '05

31 Mar '05

I would add the below: -Recommend using CentOS 4.0 -Use squid rpm, no tar (this is for new users I'm guessing). -Recommend using etherape and iptraf (available as rpms) for a graphical overview of traffic. http://etherape.sourceforge.net/ -Recommend the use of chkrootkit, and TCP Wrappers (at the least put ALL: ALL EXCEPT PARANOID in /etc/hosts.allow) to protect servers. -Provide some information about how to protect the whole network from spyware with the /etc/hosts file (a nice side benefit from doing DNS proxy). http://www.mvps.org/winhelp2002/hosts.htm -A *huge* disclaimer on running squid on a machine with a public interface. -Consider using webmin to manage this outside a GUI. -fwlogwatch can parse log files nicely. http://fwlogwatch.inside- security.de/ Biggest issue I have with your setup: -I wouldn't use Guard Dog as the GUI setup - it is very nice, but inflexible and not really meant for what you are doing. Try kmyfirewall instead if you want a GUI for iptables. It offers near complete control of iptables functions. If you can get along with using webmin, try shorewall. *If* this is going to be in a bigger than SOHO (+ 30 PC) network, go with shorewall.

Every list goes through this sort of thrashing: 1. There are some users who are too self-important to remember back when they were once n00bs. From what I've heard, these are the bulk of users on the Debian lists <grin>. 2. There are others who can provide the simple answer AND a gentle reminder where the n00b might find the answer him/herself. What's the old saying: "You ctch more flies with honey than with vinegar." 3. Then there is the group (actually, subcategory of 1) who never has any time and can't be bothered to read anything other than super-intellectual stuff and who fills the replies with "your're wasting our time." The most successful lists have a lot of users in category 2. Enjoy, -- Collins When I saw the Iraqi people voting three weeks ago, 8 million of them, it was the start of a new Arab world....

RE: [Centos] Restart centos from Commandline
by Vaneet Sharma 31 Mar '05

31 Mar '05

Well, this conversation started with me I just asked two silly questions and no where did i mention panicking or sound begging ? The reason i asked them from team was 1) i can get right answer in right time ( as there are so many distros of linux) 2) i was so eager to learn and run apache and tomcat on linux that these small things were coming as hindrance to my main aim Regarding, spoon fed, i dont think if anyone can reach the stage of joining the CENTOS mailing list is spoon fed if i can join this mailing list, install Centos on my own, run apache and run tomcat, if i can code java and restart application servers, i dont think i am spoon fed Of cours i dont know how to start centos from command line because I am not a system administrator and never was and never did. I think aim of this mailing list is to help new users get right answers in right time. There is too much information on internet which waste lot of time and also ............................ there are too many ways to do same thing. for e.g setting JAVA_HOME from bashrc and also from etc\profile Does anyone has comments from what i stated above. People here on the list have lot of ego's and they dont want to move from their point If u read my previous emails, i was criticised by 5 people, i apologised and also am thankful in giving me new direction. bottom line: if you are that much agigated, please do not answer my questions and delete the email. it is better. kind regards Vaneet -----Original Message----- From: centos-bounces(a)centos.org on behalf of Greg Knaddison Sent: Wed 3/30/2005 5:37 PM To: CentOS mailing list Cc: Subject: Re: [Centos] Restart centos from Commandline On Wed, 30 Mar 2005 14:56:00 +0100, Peter Farrow <peter(a)farrows.org> wrote: > If a question really is very simple to answer, why not just give the > answer, after all asking questions is how we all learn.... > No. RTFM and then ask questions is how we all learn. If I see a question I'm interested in that I don't know the answer to, I'll do some research and find the answer. 75% of the time that I make a post that's what it's based upon. I'm frequently happy to do it because I'm increasing my own knowledge, but when the poster is of the "I need to be spoon fed" variety and asks a follow up question that is clearly answered online it's a waste of everyone's time. Besides, how many times have you seen the "I REALLY NEED HELP RIGHT NOW OMG I CAN'T FIGURE OUT HOW TO XYZ!!!!! MY BOSS IS GOING TO FIRE ME, HELP ME HELP ME HELP ME!"? If you're used to getting spoon-fed and then get into a situation where you need help right now, spoon feeding is very unlikely to happen fast enough, but man/info/google are always there, unless you never learned to use them ;) I agree with Collins. The more people in his "group 2" the better. Respond with help and respond with a nudge.

Thank you very much Vaneet -----Original Message----- From: centos-bounces(a)centos.org on behalf of dan1 Sent: Wed 3/30/2005 9:00 PM To: CentOS mailing list Cc: Subject: Re: [Centos] Restart centos from Commandline Hello, Vaneet. I understand and agree with what you are saying. It's true that it's becoming a bit agressive and it's sad. I think that you were right to ask those questions, and I don't think that the JAVA_HOME thing did hurt to ask. It even helped me so I'm happy you asked for. You asked only one or two basic questions but even though I think we should be able to ask them. However the rule to seach first before ask is still to keep in mind. Thus, the only thing that really misses here to my point of view is a place where we can get a search on all this precious mailing list. The google option is not very good because of the delay of inclusion (1-2 days I think) and also because we get other answers and we only want answers from here (and to be sure to have all of them), knowing that here is the most appropriate information. That's why I suggest putting on the home page of CentOS.org the following search motor's URL in the 'support' section: http://search.gmane.org/search.php?query=&email=&group=gmane.linux.centos.g… I'm sure that many new comers will appreciate it a lot. This will most probably also reduce by 2 or 3 times the amount of e-mails on this list.

It isn't that you are wrong, as much as there is a perfectly valid reason not to answer those questions. Because then people will ask them. And return and ask another. They are all simple except that you become a resource, and that grows. Support Irc channels are the easiest to see this in. It isn't that it's difficult to answer these questions, it just gives no incentive for people to try and learn the answer themselves, which stunts their growth and makes them lean more on assistance. It's easier on us all to force people to try and figure out the easy answers, because if you can't figure out with google how to restart linux from the command line, how will you be able to resolve 22 dependencies with 10 perl modules that require you to debug on 3 of them error messages that.. you get the point. 2 cents. > -----Original Message----- > From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On > Behalf Of Peter Farrow > Sent: Wednesday, March 30, 2005 6:56 AM > To: CentOS mailing list > Subject: Re: [Centos] Restart centos from Commandline > > I agree, > > If a question really is very simple to answer, why not just give the > answer, after all asking questions is how we all learn.... > > Self importance really is ultimatelty self-defeating, no one knows > everything....and one day we all have to ask. > > I've been in the computing game far too long to to claim to know > definite answers to everything, the more you learn the more > > you realise you don't know! > > ;-) > > P. > > > > Joao Medeiros wrote: > > >Same happened to me when I joined the Fedora dlist and asked some > >newbie question which I'm too ashamed to remember now :-) > > > >Point is, the time it takes to reply with a "you're wasting my time" > >could actually be used to give some help.

Access to Archives

I just joined the list and am trying to look at the archives. The page http://lists.caosity.org/mailman/listinfo/centos has a link to the archives that resolves to http://localhost.localdomain/pipermail/centos/ which of course produces an error "The connection was refused when attempting to contact localhost.localdomain." What am I missing, and how can I review the archives to keep from asking obviously answered questions? Thanks. Gerry

Centos 4.0 and Named
by Robert Moskowitz 30 Mar '05

30 Mar '05

I am failing to get Named started. I copied my named.custom and zone files to a diskette from my 3.3 build. I installed 4.0 from scratch and did the updates. I edited /etc/named.conf (which I realize is a link) to include named.custom I cp named.custom into /etc (all of this was done while logged in as root) When I try to start named from the services GUI (using GNOME) and I get this error: named failed. The error was: Starting named: /etc/named.conf:67: open /etc/named.custom: file nto found /etc/init.d/named: line 56: [: too many arguements [FAILED] So what is wrong. /etc/named.custom is there. permissions look right. All done as root. Am I suppose to put named.custom in the croot area along with named.conf and set up a symbolic link (which I have forgotten how to do, as I haven't done it since '93)?

yum upgrade on 3.4 and spamassassin

30 Mar '05

Hello, I run CentOS 3.4 on 3 machines (i386). Original yum.conf If I do a yum update: No actions to take If I do a yum upgrade a machine that has no spamassassin: No actions to take If I do a yum upgrade on 2 machines that have perl-Mail-SpamAssassin-3.0.1-1 installed (3rd party rpm, more recent than the CentOS/RHEL one): I will do the following: [update: spamassassin 2.55-3.4.i386] I will install/upgrade these to satisfy the dependencies: [deps: perl-Time-HiRes 1.38-3.i386] Is this ok [y/N]: Could someone please explain this behavior? Why is yum upgrade trying to upgrade a package that is a newer 3rd party rpm, with a different name? Thanks, Francois

Yes, we use it for exactly that. It really does work well, removing nearly all spam and virus scanning with multiple virus engines. Dean

Mailscanner and Postfix
by Nigel Kendrick 30 Mar '05

30 Mar '05

I have just followed Johnny Hughes' excellent walk-through on how to install Postfix, MailScanner with ClamAV and Spamassassin and it seems to be running fine during in house testing, but I want to make sure that it behaves itself when it goes live serving about 250 users; I have read comments elsewhere both for and against the use of Mailscanner with Postfix, and when I mentioned the subject on the Postfix group I was informed I *WILL* have mail dupes and missing mail so can I have some observations from people using this setup with Centos (3.3). Also, is there a good follow up to JH's article about using that configuration with virtual mailboxes or is it easy to take the setup as outlined and 'convert' it to use them? I'm on a steep learning curve as I pull myself away from the M$ camp! Thanks
