I am compiling a custom kernel. When I do a make oldconfig, and then make rpm, I get a kernel rpm. The problem is I am not getting the initrd image. Is this normal? TIA

Iptables not blocking UDP port 53
by Sean Carolan 12 Jul '08

12 Jul '08

I'm attempting to block access to port 53 from internet hosts for an internal server. This device is behind a gateway router so all traffic appears to come from source ip 10.100.1.1. Here are my (non-working) iptables rules: -A RH-Firewall-1-INPUT -s 10.100.1.1 -m tcp -p tcp --dport 53 -j REJECT -A RH-Firewall-1-INPUT -s 10.100.1.1 -m udp -p udp --dport 53 -j REJECT Further down the ruleset I have these rules to allow traffic from everyone else. If these rules are removed then nobody can make queries, because of the final default REJECT rule. -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 53 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp --dport 53 -j ACCEPT I have used tcpdump and confirmed that packets are in fact still coming across from internet hosts. What am I doing wrong? [scarolan@host:~]$ sudo tcpdump -n udp port 53 | grep 10.100.1.1 tcpdump: listening on eth0 14:46:40.539995 10.100.1.1.60793 > 10.100.1.61.domain: 62011+ A? server.domain.com.

Laziness? ;-) ...or are we just tasty food centric? Yum yum yum !!! - rh

Firefox 3 for CentOS 4
by Filipe Brandenburger 11 Jul '08

11 Jul '08

Hi, I'm trying to make Firefox 3 work in CentOS 4. So far I was able to do it by installing the evolution28-* rpms, which have a more recent GTK, Cairo, Pango, etc. With those libs installed and configured, Firefox 3 from mozilla.org works fine. The only thing is that it doesn't use the "Bluecurve" theme as the other applications do. I was seeing that the evolution28-* packages use themes under /usr/evolution28/share/themes instead of the default /usr/share/themes. I can copy the bluecurve theme there, but the libbluecurve.so that actually themes the widgets is missing. I tried to make it work with one from CentOS 5, but with no luck. So I'm wondering. Has anyone made those evolution28-* libs work with themes other than the ones included? Or, going through another easier route: has anyone made Firefox 3 work well on CentOS 4? How? I know Firefox 3 is supposed to be released on RHEL 4.7 so, is there already any SRPM from RedHat I could use? Thanks! Filipe

Problem with Bonding Driver
by Art Age Software 11 Jul '08

11 Jul '08

Hi, I've using linux bonding in active-backup mode to combine two pairs of GigE NICs (eth0/eth1, eth2/eth3) into two logical bonds (bond0/bond1). All is working fine. However, I would like to specify a primary interface for each bond. This means I need to specify different options to the bonding module for each bond. I have tried every conceivable incantation of options and cannot get the kernel to recognize the second set of options. Initially, my modprobe.conf looked like this: alias bond0 bonding alias bond1 bonding options bonding mode=active-backup miimon=100 max_bonds=2 What I am trying to achieve should be possible by changing modprobe.conf to this: alias bond0 bonding options bond0 -o bond0 miimon=100 mode=active-backup primary=eth0 alias bond1 bonding options bond1 -o bond1 miimon=100 mode=active-backup primary=eth2 But this results in fatal errors while bringing up the bonding interfaces. Changing to this eliminates the errors, but bond1 ignores the different options: alias bond0 bonding options bond0 -o bond0 miimon=100 mode=active-backup primary=eth0 max_bonds=1 alias bond1 bonding options bond1 -o bond1 miimon=100 mode=active-backup primary=eth2 max_bonds=1 I have tried many other combinations as well: install bond1 /sbin/modprobe --ignore-install bonding -o bond1 mode=active-backup primary=eth2 Nothing works. I also came across this note in the bonding docs: "NOTE: It has been observed that some Red Hat supplied kernels are apparently unable to rename modules at load time (the "-o bond1" part). Attempts to pass that option to modprobe will produce an "Operation not permitted" error. This has been reported on some Fedora Core kernels, and has been seen on RHEL 4 as well. On kernels exhibiting this problem, it will be impossible to configure multiple bonds with differing parameters." I have seen that error as well with certain combinations of options in my modprobe.conf. Am I simply out of luck here? Does anyone know of a solution? Thanks.

Finding a python module

libc-client 2007 conflict when updating
by Kenneth Porter 11 Jul '08

11 Jul '08

FYI for others who might encounter this. I just did a yum update (C5.1) and after a very long download of packages I get a transaction test failure: Transaction Check Error: file /usr/lib/libc-client.so.2007 from install of libc-client2007-2007b-1.el5 conflicts with file from package libc-client-2007-3 I just realized this is coming from a conflict with a custom build I made of that package so that I could install uw-imap-devel as a prereq for building an asterisk package. It looks like I can just erase those two packages and the yum update should go through.

CentOS 5.2 VMI support
by Ruslan Sivak 11 Jul '08

11 Jul '08

I'm using VMWare Server 2 RC1 to on top of CentOS 5.2 x86_64 running a CentOS 5.2 i386 guest. I have enabled VMI in VMware, so I guess it won't let me install if VMI wasn't available in the kernel? How do I know whether VMI is supported/enabled and what performance benefits can I expect from it? I'm still not getting full hard drive speeds (only getting about 1/3 when using hdparm -t ). Russ

CentOS 5.2 - /usr/sbin/httpd: double free or corruption (!prev) error
by J Potter 11 Jul '08

11 Jul '08

Hi List, We've been seeing the following error on a CentOS 5.2 x86_64 / 2.6.18-92.1.6.el5 install (from /var/log/httpd/error): *** glibc detected *** /usr/sbin/httpd: double free or corruption (! prev): 0x00002ad8ebed2d80 *** [Thu Jul 10 19:12:19 2008] [notice] child pid 5261 exit signal Segmentation fault (11) [Thu Jul 10 19:12:48 2008] [notice] child pid 12180 exit signal Segmentation fault (11) ... The following packages are installed: glibc-2.5-24 httpd-2.2.3-11.el5_1.centos.3 mysql-server-5.0.45-7.el5 mysql-5.0.45-7.el5 php-gd-5.1.6-20.el5 php-mysql-5.1.6-20.el5 php-common-5.1.6-20.el5 php-pdo-5.1.6-20.el5 php-cli-5.1.6-20.el5 php-5.1.6-20.el5 php-imap-5.1.6-20.el5 If we remove the php-pdo / php-mysql packages, then the crashes stop. But, we need those packages, so that's not a solution. Any ideas as to what might be causing this? We've tried the obvious things; the only thing that's not "vanilla" here are a few settings in /etc/php.ini (having to do with max execution time and max memory). The php code that's being run does have its share of php warn/notices: PHP Notice: Undefined index: d in [snip] on line 1699 PHP Notice: Undefined index: verbose in [snip] on line 1819 PHP Warning: Invalid argument supplied for foreach() in [snip] on line 1695 So I would not be surprised if it is tickling something out of the ordinary, but it should still not be causing a segfault! Any thoughts as to what's going on here, and how to fix it? I'm tempted to install php 5.2.6 from utterramblings repo, to see if that works around this. Thanks!

Multiple LVM snapshots
by Raja Subramanian 11 Jul '08

11 Jul '08

I have a Centos 5.2 fileserver running LVM2, ext3 and Samba. I want to periodically snapshot a filesystem and offer them as read only backups to my users. I'm looking for something similar to what's available on Netapp filers. I am successfully able to create snapshots using LVM. But are there any performance issues in having multiple snapshots of the same filesystem at the same time? Is there any other way i can offer filesystem snapshots to my users? Thanks for any guidance! - Raja

redirecting when behind a firewall
by bruce 11 Jul '08

11 Jul '08

Hi.. I know this isn't a centos/rhel/fedora issue... but i'm hopeful that someone might have an answer!!! thanks VVVVVVVVVV Got a bit of an issue here, that I can't seem to resolve. I have a test domain on a dynamic service (dyndns.org) the test domain is foo.gotdns.com, which i have pointing to my external cable/dsl address. Here's my issue, I would really like to be able to have the external user be able to see multiple websites which might be sitting on different physical machines/apache servers within my network. Behind the modem, I have a firewall which is set up to port-forward the traffic to a machine with my network. So, for my example, the machine is dog (192.168.1.52), and the "foo.gotdns.com" would point to the app on the machine, based on the vhost setup in the dog httpd.conf file. However, I would also like to have multiple external test sites/domains, each of which might point back to sites on different internal servers. The forwarding capability of the router only allows for all wan * (addresses) to be forwarded to a given internal machine. At the same time, the external/internal ports have to match. So i don't have the ability to do something like "forward foo.gotdns.com to machine1, and forward foo2.gotdns.com to machine2" which is exactly what i'm trying to accomplish!! I've been looking into using vhosts, and the redirect functionaility, but I can't seem to get it to work, using the external domain name. So. i'm trying to: -be able to access multiple test sites, on multiple servers from a browser external to my network -be able to access the same sites, from inside my network, using the local/internal namespace -be able to access the same sites, from inside my network, using the external namespace (testing purposes) I've looked high/low for how to accomplish this with no real luck. thanks ps. I've seen others who've been looking for similar solutions, so this would definitely help. ps. I'm able to do a redirect from one server to another, if I restrict to using internal addresses. Just can't get the external stuff to work..

bind9, SELinux, ServFail
by Meenoo Shivdasani 11 Jul '08

11 Jul '08

I just set up a CentOS 5.2 system with bind9 (9.3.4-6.0.1.P1.el5) and I'm running up against a problem that seems to be related to SELinux. If I set named_disable_trans to 1, everything works as expected, but if I leave it enabled the server will only give me data for the zones for which it is authoritative. For external sites it returns a ServFail error. This is with nslookup and dig. If I start named from the command line with the command "named -u named", the server returns the expected response. tcpdump shows that the server is querying itself and getting a ServFail response. I figure that I'm missing something really basic, but not sure what. Debug logs show this: FAIL: clientmgr @0x2b491728c1d0: createclients clientmgr @0x2b491728c1d0: recycle . . . fctx 0x2b49173153e0(www.google.com/A'): shutdown client 192.168.213.111#33096: view internal: error Succeed: clientmgr @0x2b109771bd30: createclients clientmgr @0x2b109771bd30: create new . . . res 0x2b109778cae0: dns_resolver_prime res 0x2b109778cae0: priming createfetch: .

/etc/pam.d/system-auth changes in update
by listmail 11 Jul '08

11 Jul '08

I just did an update, and PAM was was one of the modules. Yum has placed /etc/pam.d/system-auth.rpmnew and it's different than the existing file, which is actually a link to system-auth-ac. The files are slightly different, and I'm wondering if the differences are important. I can't find any docs on the reason for the change, so before I spend time becoming a PAM expert, I'm wondering if anyone knows why this change was made, or were it might be documented. Thanks, --Bill

Evolution in CentOS 5.2
by MHR 10 Jul '08

10 Jul '08

(Probably OT) Has anyone else noticed these flaky (new?) behaviors in Evo since the 5.2 upgrade: - REALLY slow saving messages from inbox to another folder - search capability separated by folder instead of overall (with no option for control) - failure to autocomplete email addresses for known contacts I think that's it. I was wondering if it was just me, or if others had noticed this. (If it's just me, there is no need to reply....) Thanks. mhr

Problems with bind on 5.2
by Scott Silva 10 Jul '08

10 Jul '08

I'm having some trouble getting reverse zones right on 5.2. The zone files worked fine on a CentOS 4.6 machine, and the forward zones moved to the new server seem OK. But for some reason I can't get anything but servfail's on remote queries to the machine. But for some reason they will answer fine if I run "host ip.ad.dr.ess" on the local machine. I stopped the firewall to help debug this, but it still fails. Bind is listening on all the machines ip addresses. -- MailScanner is like deodorant...

Bind update overwrites named.conf
by Chris Miller 10 Jul '08

10 Jul '08

I just had a customer's bind server lose all of it's local DNS records. Yum updated the bind packages this morning at ~6am, and replaced the original /etc/named.conf file, saving the old as named.conf.rpmsave. This seems like the opposite of what it should have done (i.e. save the new file as named.conf.rpmnew). There does not appear to be any difference between the originally shipped conf file and the new one, suggesting that the file should not have been replaced at all. Just wanted to through this out there in hopes it helps someone else before the phone starts ringing... CentOS release 4.6 (Final) Jul 09 05:59:25 Updated: bind-devel.i386 20:9.2.4-28.0.1.el4 Jul 09 05:59:29 Updated: bind-chroot.i386 20:9.2.4-28.0.1.el4 Chris

rsh problems in CentOS 5.2 (was "cvs command failure on 5.2")
by MHR 10 Jul '08

10 Jul '08

Okay, I've narrowed the problem down quite a bit. As previously reported, in CentOS 5.2 I get this: $ cvs log Makefile poll: protocol failure in circuit setup cvs [log aborted]: end of file from server (consult above messages if any) Turns out this is a problem with rsh: $ rsh khan ls connect to address 10.24.15.48 port 544: Connection refused Trying krb4 rsh... connect to address 10.24.15.48 port 544: Connection refused trying normal rsh (/usr/bin/rsh) poll: protocol failure in circuit setup Now, if I just reomtely login to khan (our cvs server), I get this: [mrichter@sushi ~]$ khan connect to address 10.24.15.48 port 543: Connection refused Trying krb4 rlogin... connect to address 10.24.15.48 port 543: Connection refused trying normal rlogin (/usr/bin/rlogin) Last login: Fri Jul 4 18:19:01 from viper [mrichter@khan mrichter]$ Voila - I'm logged in.

Need help with awk one-liner

10 Jul '08

This awk command pulls URLs from an apache config file, where $x is the config filename. awk '/:8008\/root/ {printf $3 "\t"}' $x The URL that is output by the script looks something like this: ajpv12://hostname.network.company.com:8008/root Is there a way to alter the output so it only shows "hostname" by itself? Do I need to pipe this through awk again to clean it up?

can I use CentOS as a antivirus / spam filter / HTTP AV gateway?
by Rudi Ahlers 10 Jul '08

10 Jul '08

Hi all I've been thinking about using CentOS on a Dell R200 server and turn it into a firewall / network monitor / traffic shaper in our datacentre, instead of using a dedicated firewall device. One of the devices that I have been looking at, with my limited budget, is the D-Link DFL 860 - http://www.netdefend.eu/Product.aspx?m=15&ref=DFL-860 It provides AV, SPI, VPN, DOS, P2P, etc protection. Most of this can be done with Linux as well, but I'm not 100% sure about the AV part. How will I use / setup CentOS to check all traffic coming in & out (HTTP, SMTP, POP3, IMAP, etc) for virusses and clean them? We host both Windows & Linux servers, and I'm not too worried about the Linux servers, but Windows needs a lot of extra protection. -- Kind Regards Rudi Ahlers CEO, SoftDux Web: http://www.SoftDux.com Check out my technical blog, http://blog.softdux.com for Linux or other technical stuff, or visit http://www.WebHostingTalk.co.za for Web Hosting stuff

My ISP assigned prefix is: 2607:F4B8:3::/48 So I am building my internal IPv6 firewall/router/ etc. I want to have a static IPv6 address on its eth0 so that I can create static v6 routes to it from the gateway. I add the following lines to ifcfg-eth0: HWADDR=00:40:F4:05:A8:F1 IPV6INIT=yes IPV6_AUTOCONF=no IPV6ADDR="2607:F4B8:3:1" if-up eth0 gets the error: Error: an inet prefix is expected rather than "2607:F4B8:3:1/64". ERROR : [ipv6_add_addr_on_device] Cannot add IPv6 address '2607:F4B8:3:1/64' on dev 'eth0' What is missing? Why is it not building an address of 2607:F4B8:3:1:0:40:F405:A8F1 ? I am reading: file:///usr/share/doc/initscripts-8.45.19.EL/sysconfig.txt for my 'inspiration'. Other sources are welcome... OH, /etc/sysconfig/network does have the line: NETWORKING_IPV6=yes

what does "not found" mean in a DHCPRELEASE context?
by David Mackintosh 10 Jul '08

10 Jul '08

I have a CentOS 4.6 server running dhcpd. One of my client devices (a Panasonic KX-HCM280A camera) is trying to get a lease from that server. I can see the device accept a lease (it is a reservation), however it always releases the reservation after about 25 seconds: Jul 10 10:30:49 stargate dhcpd: DHCPDISCOVER from 00:80:f0:56:46:30 via eth0 Jul 10 10:30:49 stargate dhcpd: DHCPOFFER on 172.31.14.13 to 00:80:f0:56:46:30 via eth0 Jul 10 10:30:49 stargate dhcpd: DHCPREQUEST for 172.31.14.13 (172.31.0.1) from 00:80:f0:56:46:30 via eth0 Jul 10 10:30:49 stargate dhcpd: DHCPACK on 172.31.14.13 to 00:80:f0:56:46:30 via eth0 Jul 10 10:31:16 stargate dhcpd: DHCPRELEASE of 172.31.14.13 from 00:80:f0:56:46:30 via eth0 (not found) If I remove the reservation and reset the camera, it does the same thing with a dynamic lease; however in that case the message is Jul 3 09:48:05 stargate dhcpd: DHCPDISCOVER from 00:80:f0:56:46:30 via eth0 Jul 3 09:48:06 stargate dhcpd: DHCPOFFER on 172.31.9.91 to 00:80:f0:56:46:30 via eth0 Jul 3 09:48:06 stargate dhcpd: DHCPREQUEST for 172.31.9.91 (172.31.0.1) from 00:80:f0:56:46:30 via eth0 Jul 3 09:48:06 stargate dhcpd: DHCPACK on 172.31.9.91 to 00:80:f0:56:46:30 via eth0 Jul 3 09:48:19 stargate dhcpd: DHCPRELEASE of 172.31.9.91 from 00:80:f0:56:46:30 via eth0 (found) ...ie "(found)" instead of "(not found)". I should mention that I have several other cameras of the same type which are working, so this is most assuredly a problem with the camera itself, but I was still wondering: Does anyone know what dhcpd (or the device) is trying to tell me with this message? -- /\oo/\ / /()\ \ David Mackintosh | dave(a)xdroop.com | http://www.xdroop.com

Slow HVM IO performance with newer kernels
by henry ritzlmayr 10 Jul '08

10 Jul '08

Hi list. I am testing CentOS 5.2 now. I experience much slower IO under HVM Guests with the newer kernels, so I started some measurements. DOM-0 is a fully upgraded CentOS 5.2. DOM-U is CentOS 5.0 not upgraded at all for testing purposes. DOM-U sits on an LVM Volume. No other services are running. Hardware was freshly rebooted every time. within DOM-0 dd if=/dev/vgpentanol/lvol2 of=/dev/null bs=1M count=1000 gives 134 MB/s so thats the bare metal value. within DOM-U dd if=/dev/hda of=dev/null bs=1M count 1000 gives 50 MB/s with DOM-0 kernel 2.6.18-53.1.19.el5xen 10 MB/s with DOM-0 kernel 2.6.18-92.1.1.el5xen 10 MB/s with DOM-0 kernel 2.6.18-92.1.6.el5xen so there has been a drop to 20% of the performance within 2.6.18-53. Any Ideas? The machine is a test system - so I am open to any changes in configuration you might suggest. As a side note: A PV Guest gets 85 MB/s no matter which kernel. Henry

yum dependency problem
by fred smith 10 Jul '08

10 Jul '08

Hi: Today when I do yum update I get this: Resolving Dependencies --> Running transaction check --> Processing Dependency: libdirectfb-0.9.so.25 for package: mplayer ---> Package directfb.i386 0:1.0.1-1.el5.rf set to be updated ---> Package amrnb.i386 0:7.0.0.2-1.el5.rf set to be updated ---> Package gsm.i386 0:1.0.12-1.el5.rf set to be updated --> Finished Dependency Resolution Error: Missing Dependency: libdirectfb-0.9.so.25 is needed by package mplayer and I have to admit I don't understand that.... it says it's going to update directfb.i386 then it says directfb is required by mplayer. Huh? perhaps it means it's trying to replace my existing directfb with a DIFFERENT verson and can't because mplayer needs the existing one? the existing directfb I have is: directfb-0.9.25.1-1.el5.rf which came from the same repo as my mplayer: mplayer-1.0-0.38.rc1try2.el5.rf so am I to assume that some other repo (with a greater priority, since I'm using the priority plugin) is trying to overwrite the one I got from the rf repo? the base repos (base, updates, addons and extras) are all priority 1, centosplus and contrib are 2. rpmforge is 10. that's all there are. What's wrong here?

Total lockup caused by Shift-{print screen}
by Robert Nichols 10 Jul '08

10 Jul '08

I just had the misfortune to press Shift-{print screen} accidentally while in a Gnome desktop, and the result was a completely unresponsive system where the only recovery was a power switch initiated shutdown. Further investigation shows the runaway creation of gnome-screenshot processes. System is CentOS 5.2 fully updated on an Intel i686. Suggestions about what component should receive the bugzilla report are welcome. -- Bob Nichols "NOSPAM" is really part of my email address. Do NOT delete it.

CentOS 5.2 kernel [2.6.18-92.1.1.el5] crashes on dual-PIII Compaq ProLiant 3000
by Wojtek Pilorz 09 Jul '08

09 Jul '08

After yum upgrade, the new CentOS5 kernel [ kernel-2.6.18-92.1.1.el5.i686 ] crashes each time early in boot process on Compaq ProLiant 3000 with dual Pentium3 CPU (600 MHz, CPU0: Intel Pentium III (Katmai) stepping 03, CPU1 the same). I get kernel panic at powernowk8_init+0x05e/0x1c3. The previous kernel [ kernel-2.6.18-53.1.21.el5.i686 ] seems to work fine. I am wondering if anyone has met this on PIII CPU ? I have found 99.9% identical problem on http://www.nabble.com/net-5501-and-RHEL5.2-td18024549.html (only esp and task slightly different from what I have seen on screen after crash, all other registers, call trace, code bytes identical to my case) , but that was on a different CPU. On the other hand, I run CentOS upgraded to 5.2 on a home PC with PIII (single CPU, Abit motherboard with i440BX chipset) with no problem. Is it normal, that powernowk8_init gets called on PIII CPU? Best regards, Wojtek

Flaky desktop audio behavior.
by William L. Maltby 09 Jul '08

09 Jul '08

Might have some kind of bug here. I want to know if anybody else is seeing this. It's happened twice now, so I should be able to repeat it. $ rpm -q centos-release centos-release-5-2.el5.centos On my desktop, I "su -" to another user. Then "nohup thunderbird", it gets the mail and plays the announcement. ISTM this is an error right off the bat as this user is not the desktop owner. But that's not the main point. I really am OK with that behavior in my instance. The problem is that the sound system goes muted, as indicated by the volume control on my desktop panel and I can't recover from it except by a reboot. When I try to open the sound control panel, I get an error panel saying "No volume control GStreamer plugins and/or devices found". If I just try to un-mute, there's no error message but the status does not change. I've attached a snapshot of the error panel. Further, in chasing another problem that Jim (hce) had, we have done this: # find . -type f -exec echo {} \; -exec cat {} \; >/tmp/asound.play.bug Normally it acts as expected but now I get this. cat: ./acpi/event: Device or resource busy cat: ./sys/net/ipv6/route/flush: Operation not permitted cat: ./sys/net/ipv4/route/flush: Operation not permitted cat: ./sys/fs/binfmt_misc/register: Invalid argument cat: ./sysrq-trigger: Invalid argument and it hangs right there. <Ctl>-<C> breaks OK. I feel it might be related to Jim's problem. I feel it might be a bug. Can anybody reproduce? I think the T'bird step is coincidental. I think any sound played as another user should reproduce it. Hmmm ... I might be assuming to much if I assume another user is significant. TIA -- Bill

Need basic PPPoE startup help
by Robert Moskowitz 09 Jul '08

09 Jul '08

I need basic PPPoE startup help. adsl-start DID bring up my PPPoE link (ppp0) to my ISP over eth0 via the DSL modem/bridge. My IPv4 CIDR block is routing and Shorewall is doing the firewalling. But shorewall has to be started after ppp0 is up and working. For now this means running shorewall restart (or start?). Shorewall 4.2 will have a way to restart shorewall without recompiling, I learned on the their list. In /etc/sysconfig/network-scripts/ifcfg-ppp0 I have: BOOTPROTO=dialup NAME=DSLppp0 DEVICE=ppp0 TYPE=xDSL ONBOOT=no Should ONBOOT be changed to yes, or is there some startup script that I should add the /sbin/adsl-start ppp0 command line followed with the shorewall restart command? I am away at IEEE 802 plenary meeting next week, and I need this to be automated in case of system glitches. Also sometimes the Speedstream just stops forwarding datagrams. Supposedly if it overheats. This requires a power recycle for the speedstream (and my ISP will not use anything else for the modem services). I suspect this will glich the PPPoE connection as well, so I will need some sort of watchdog and a restart of ppp0 and Shorewall. Attached is a rather large script of a user that I picked up on the Shorewall list for some Linux distro. I am NOT a script reader, let alone writer. Should I use this (how would I modify it for Centos and a ppp0 interface) and where would I place it to run as needed? ======================================================= #!/usr/bin/perl -w #THIS SCRIPT CREATED BY EJM (alias Erik Mundall) IN ORDER TO MAINTAIN A CONSTANT CONNECTION WITH THE TWO #PPPOE ADSL LINES WHICH HAVE PROVEN TO BE UNRELIABLE/UNSTABLE. 15 APRIL 2008 # #THIS PROGRAM NEEDS TO FOLLOW THE FOLLOWING ROUTINE IN ORDER TO MAINTAIN CONNECTIVITY OF THE TWO PPPOE LINES #AND TO SHARE THE INTERNET LOAD ACROSS THOSE AND ACROSS THE STATIC LINE # #THE STATIC SHOULD NEVER FAIL.

I performed a clean minimal CentOS 5.2 install, fully updated the system, and then added the ATrpms repository. When I perform an update after adding the ATrpms repository, the package pm-utils is updated the the ATrpms repository. My understanding is there should not have been any updates as the stable version does not update system packages, right? "The CentOS 5/RHEL 5 repository from atrpms.net is safe to use, if you only use the stable version. Packages in there do not overwrite system packages." [1] If this is true, why did this package get updated? Thanks, Kenneth [1] http://wiki.centos.org/AdditionalResources/Repositories/

How to Auto Add forward slash "/" when accessing a link/url through ProxyPass
by ankush grover 09 Jul '08

09 Jul '08

Hi Friends, I am using Centos 5.2 and using ProxyPass to access applications running on other servers. Everything is working fine except for one of the applications I need to auto add forward slash when any user tries to access that application. For ex ProxyPass /testdiary http://testdiary.example.com/ ProxyPassReverse /testdiary http://testdiary.example.com/ If somebody access directly http://testdiary.example.com/ everything is coming means the login page but when the same link is accessed through apache server on which proxypass is running then the login page does not appear(http://portal.example.com/testdiary). How can I auto add "/" when somebody put the url http://portal.example.com/testdiary which should first be converted/redirected to http://portal.example.com/testdiary/ (auto added forward slash). I have the below lines added in httpd.conf file RewriteEngine On RewriteCond %{REQUEST_URI} /testdiary RewriteRule /testdiary(.)$ /testdiary/ ProxyPass /testdiary http://testdiary.example.com/ ProxyPassReverse /testdiary http://testdiary.example.com/ Please let me know if you need any other information. Regards Ankush

Hi, I need to run /bin/mount and /sbin/mount.cifs commands as nobody user (it has (bin/bash shell). So, I've edited /etc/sudoers and added: Cmnd_Alias CMD_MOUNT = /bin/mount Cmnd_Alias CMD_CIFS ) = /sbin/mount.cifs nobody ALL = NOPASSWD: CMD_MOUNT nobody ALL = NOPASSWD: CMD_CIFS But when I run the command as nobody (in the shell), I get the error: "mount error 1 = Operation not permitted" Any ideas ? Any help would be appreciated. Warm Regards, Mário Gamito

by Rudi Ahlers 09 Jul '08

Hi all If I do a "dig mydomain.co.za" from a Linux server, how do I know which DNS nameserver returns the queries? I seem to have a faulty DNS server, but can't see which one, so I want to find out which nameserver (if there's 4 - ns1.myserver, ns2.myserver, ns3.myserver & ns4.myserver) returns the queries? -- Kind Regards Rudi Ahlers CEO, SoftDux Web: http://www.SoftDux.com Check out my technical blog, http://blog.softdux.com for Linux or other technical stuff, or visit http://www.WebHostingTalk.co.za for Web Hosting stuff
