Compilation problem - CentOS 4.2 - x86_64
by kadafax 18 Dec '05

18 Dec '05

Hi list, Here it is: I have compiled with no problem courier-imap-4.0.4 on this arch (x86_64). Now I want to update my install with 4.0.6. I want to do this because the server is not yet in a production state, so if a major flaw affects courier-imap in the future, I could react more quickly. And indeed I'm encountering problems with the make process (Since I initialy build courier-imap from sources and that I dont want FAM, I'm not using the rpmbuild process). I've stricly followed the INSTALL's instructions. I believe the problem comes from the mixed libraries living on the system (x86_64 and, for compatibility purpose, i386) and I didn't find a workaround on this. I'm near to switch to dovecot if it can handle quite large amount of users (500-1000 accounts). That would be bad because I think courier-imap is well doing its job. By the way, someone tolds me that courier-imap and RHEL4 (and clones) is a bad idea, someone can confirm? So: [user@host courier-imap-4.0.6]$ ./configure --with-redhat ... // process goes ok, no warning no errors configure: creating ./config.status config.status: creating Makefile config.status: creating imapd.dist config.status: creating imapd-ssl.dist config.status: creating pop3d.dist config.status: creating pop3d-ssl.dist config.status: creating testsuitefix.pl config.status: creating mkimapdcert config.status: creating mkpop3dcert config.status: creating imapd.cnf config.status: creating pop3d.cnf config.status: creating config.h config.status: executing depfiles commands [user@host courier-imap-4.0.6]$ make ... // I'm just pasting the first errors, the others seems to come from the first ones anyway: In file included from /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/bits/stl_tree.h:66, from /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/set:66, from maildirkeywords.h:435, from maildirkeywords4.cpp:9: /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/bits/stl_algobase.h:64:28: bits/c++config.h: No such file or directory In file included from /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/bits/stl_algobase.h:70, from /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/bits/stl_tree.h:66, from /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/set:66, from maildirkeywords.h:435, from maildirkeywords4.cpp:9: /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/iosfwd:46:29: bits/c++locale.h: No such file or directory /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/iosfwd:47:25: bits/c++io.h: No such file or directory In file included from /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/bits/stl_tree.h:67, from /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/set:66, from maildirkeywords.h:435, from maildirkeywords4.cpp:9: /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/bits/allocator.h:52:31: bits/c++allocator.h: No such file or directory In file included from /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/bits/stl_tree.h:67, from /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/set:66, from maildirkeywords.h:435, from maildirkeywords4.cpp:9: /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/bits/allocator.h:80: error: expected template-name before '<' token /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/bits/allocator.h:80: error: expected `{' before '<' token /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/bits/allocator.h:80: error: expected unqualified-id before '<' token /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/bits/allocator.h:80: error: expected `;' before '<' token In file included from /usr/lib/gcc/x86_64-redhat-linux/3.4.4/../../../../include/c++/3.4.4/set:67, from maildirkeywords.h:435, from maildirkeywords4.cpp:9: ...

Install problems for a Toshiba NW24XCD
by Robert Moskowitz 17 Dec '05

17 Dec '05

I am trying to install Centos on my old Portege 2490CT. Actually a pretty good box, but it does not support USB booting. Only HDD, FDD (interestingly a USB device), 'CD-Rom', or LAN. The only CDroms I have is a nice USB drive and an old PCMCIA toshiba NW24XCD drive. I have not gotten this system to boot off of my USB CDrom. It will boot of the NW24XCD. So I put the CentOS disk 1 in the drive and boot. Boot seems to go OK, it asks my the language preferences but then gives me the dialog: What type of Media contains the packages to be installed? When I select CDrom I get the dialog: Unable to find may devices of the type neededfor this installation type. Would you like to manually select your driver or use a driver disk? And there is a list of a bunch of drivers. I have a hunch that my PCMCIA NW24XCD is not a standard supported drive. :( So what from the list do I select? Or where do I get a driver disk? POI: I am not a Unix skilled person. I can get by with VI and the like, but otherwises I just have not devoted the time needed... HELP?

SMB server with CentOS 4
by Ugo Bellavance 17 Dec '05

17 Dec '05

Hi, I need to set up a small server for a group of ~10 employees (all using Windows 2000/XP, used to use a windows 2000/exchange setup). I have a linux server already running CentOS 4, so I'd like to do all I can with this. I thought about using Samba for file/print sharing and OpenXchange (commercial version) to have a nice collaborative/mail/calendar/etc server. Of course, it would probably be the dhcp and internal DNS server. I started reading the Samba doc, but it is rather long. I planned on using this server as a PDC so that it is not too different from using their former windows 2000 server. I'll be managing this server, which is currently a staging server for web development (php/mysql/cvs). Anyone has a opinion on this, or better ideas? My backups will be based on utilities and mondorescue, kept on a internal (cold-swap drawer) hard-drive that I would take every week (2-drawers rotation). Any recommendations welcome, will provide more details if needed. TIA, -- Ugo -> Please don't send a copy of your reply by e-mail. I read the list. -> Please avoid top-posting, long signatures and HTML, and cut the irrelevant parts in your replies.

scsi tape device support
by Marc Peiser 17 Dec '05

17 Dec '05

I'm trying to get a scsi tape device (Sony SDX-D500V) working on my dell 2450 running centos 4.2. I can see the device (ch1, id2) using the dell bois raid utility, but once booted into linux I can't see any mention of it in the logs or dmesg. Do you know if the generic kernel (2.6.9-22.0.1.ELsmp) supports this tape device? Can anyone give me any pointers in getting this device working. Regards, Marc

mozilla bug?
by Robert 17 Dec '05

17 Dec '05

I had an embarrassing experience today, attempting to demonstrate that with gmail one can use the web interface when he must or use the pop/smtp interface or use both at the same time. The web interface would not work with mozilla-1.7.12-1.4.1.centos4. A quick check showed that firefox-1.0.7-1.4.1.centos4 has the same symptom -- that is, displays a page containing nothing but "Loading..." after user and password are entered. Konqueror works fine, as does mozilla-1.7.8-2 on an FC4 box I have. I can find nothing on this list regarding this and will admit that since the common denominator appears to be the "1.4.1.centos4", I haven't checked mozilla bugzilla. Can someone confirm that my imagination hasn't run wild?

Belking USB KVM switch & the unresponsive mouse - it works now
by Ron Jones 16 Dec '05

16 Dec '05

>>Tried switching ports on KVM? I didn't think of that, so on your suggestion, I did try it, but still didn't get any love from the mouse >>when booting, let the boot process finish before you switch >>ports. Other than that, my two belkin 6 porters work like a champ! >>Hope that helps.... You know... I can't explain it, but it works. I was really hoping to be able to offer back a set of clearly defined steps to follow in order to resolve this question (I really like it when I see them, so I try to do that whole 'golden rule thing). I let the computer boot completely, leaving the kvm set on my linux box for the entire cycle. Upon logging in and entering 'startx' I thought for a moment that it didn't work, and the mouse was still sitting there, unresponsive in the center of the screen. However, after a few seconds, I noticed that it moved. I had occasion to add a new UPS to the server last night, and when I restarted, I did NOT set the KVM to view the CentOS screen. Instead, I was busy with some work on my Windows desktop. When I switched over to take a look, I noticed that after starting up the X server, my mouse worked just fine. It figures! Unfortunately, it kind of "just works" now, I don't know whether it's in the completion of the boot cycle before switching over, or whether there are other factors involved. >>They had a firmware patch for the kvm on the site, >>but it wasn't exactly a painless progress to update the firmware. Thanks, I didn't know that, I hope that I don't need it. Ron Jones Alpharetta, GA

SELinux threads, cynicism, one-upmanship, etc.
by Lamar Owen 16 Dec '05

16 Dec '05

After reading through the various SELinux threads, I really became quite perturbed. I mean, really quite perturbed. As an IT Director (and the entire IT department, currently), if I were hiring a sysadmin I know for a fact that someone whose first response to a question on why something doesn't work is 'turn it off' would not get a job here. Neither would a sysadmin with as much cynicism as has been displayed, or an automatic 'it broke things' when something new (and in fact improved) comes along get a job here. Do realize that this list is archived, and that many people who are hiring might use Google to find your name (or mine, for that matter). No, I would hire someone who would read enough of the friendly manual to know where to look and who to ask to find the fix for the real problem. The real fix is there; thanks to the KMail developers for including a 'mark as important' feature so I can find that message amongst the drivel in that thread easily (well, actually I'll probably just delete everything but the real solution). It is the lazy sysadmin who just turns things off without an understanding as to why they are turned off; don't give me the 'overworked' line; you had enough time to post here on the brokenness of SELinux, so you had enough time to find the problem's real source. I am not interested in hiring lazy sysadmins, once I get to hiring. Bryan Smith, for all the verbosity he is known for, doesn't seem to be lazy and could likely hold the job; Craig White likewise, among many others here. I won't name all the names to protect the guilty. :-) The main reason I think sysadmins in general seem to hate SELinux is the 'Mandatory' part of 'Mandatory Access Control' : that is, superuser power is too addictive to get rid of, and SELinux can do away with 'superuser' powers entirely. AND THAT IS A GOOD THING. Yes, it really is. The buffer overflow exploit for those root-running daemons doesn't stand a chance even if it gains root, as long as the selinux policies are set properly. And, yes, it is possible to set the policies properly; any daemon whose developers feel that it needs to be exempt from such might have a problem running on my servers. In a nutshell, SELinux is on and enabled everywhere here; I can't seem to find any measureable speed difference between SELinux targeted, permissive or off; it is unobtrusive in my experience, and it does indeed help protect internet-facing systems from unknown buffer overflows. This is a good thing, and I am convinced that the minor inconvenience of learning a new security tool's configuration is a great tradeoff; especially when the alternative is a compromised system. As there is no such thing as a 100% secure system, anything that improves security but, when properly configured, doesn't impact usability is a BIG WIN in a my book, and probably in many other IT Directors' books too. I have been running Red Hat Linux on internet-facing servers for quite a while, now, and in my opinion and experience, SELinux is the best thing to happen to Linux since 0.13 was released. It's about time the antiquated default Unix permissions system was overhauled. Yes, it requires study, thought, and care. I would expect nothing less of any sysadmins who would work under me. Also, as one poster wrote, SELinux is NOT a *service* but is indeed the Bully Boss of the system. This is also a good thing for internet-facing servers to have; how is the machine supposed to know that the Real Root has logged in, and that that process with euid 0 really was started by the Real Root? The Real Root should take the time to configure in to the policies those things the Real Root would normally do (you know, things like backups and the like, along with other normal activities), but then block those actions that the Real Root would not do (like install a rootkit; yes, a properly configured SELinux can prevent installation of a rootkit on your machine even if it gets 'rooted'). The power of the properly configured Mandatory Access Control system (The Bully Boss) is completely in the control of the Real Root, but untouchable by those Fake Roots who wish to do your system harm. This is again a good thing, and one I would think Diligent Sysadmins would be falling over themselves trying to learn and deploy. -- Lamar Owen Director of Information Technology Pisgah Astronomical Research Institute 1 PARI Drive Rosman, NC 28772 (828)862-5554 www.pari.edu
