New firefox causing anyone else problems - CentOS 4.X?
by William L. Maltby 31 Mar '08

31 Mar '08

Looks like Firefox may be getting another update soon, if my problem is not atypical. Prior to the latest, had NP for *months*. Anyone else seeing any problems? BTW, running the recent Java console from sun that was detailed in another thread a week or two back with Firefox. Had NP prior to the latest update, if that offers any useful info. Would like to test the openjdk for us if it's applicable to 4.x. If not, I can still test it on the 5.x machine. # uname -a Linux centos01.homegroannetworking 2.6.9-67.0.7.EL #1 Sat Mar 15 06:19:12 EDT 2008 i686 athlon i386 GNU/Linux >From rpm -qa --last: krb5-workstation-1.3.4-54.el4_6.1 Thu Mar 27 14:14:55 2008 krb5-devel-1.3.4-54.el4_6.1 Thu Mar 27 14:14:51 2008 krb5-server-1.3.4-54.el4_6.1 Thu Mar 27 14:14:49 2008 firefox-1.5.0.12-0.14.el4.centos Thu Mar 27 14:14:39 2008 krb5-libs-1.3.4-54.el4_6.1 Thu Mar 27 14:14:16 2008 jre-1.6.0_05-fcs Mon Mar 17 09:13:36 2008 kernel-smp-devel-2.6.9-67.0.7.EL Sun Mar 16 06:02:20 2008 kernel-hugemem-devel-2.6.9-67.0.7.EL Sun Mar 16 06:01:42 2008 kernel-doc-2.6.9-67.0.7.EL Sun Mar 16 06:01:35 2008 kernel-2.6.9-67.0.7.EL Sun Mar 16 06:01:21 2008 kernel-devel-2.6.9-67.0.7.EL Sun Mar 16 06:00:00 2008 >From the messages log: (sorry about the wrapping) Mar 30 14:53:40 centos01 kernel: general protection fault: 0000 [#1] Mar 30 14:53:40 centos01 kernel: Modules linked in: loop vfat fat radeon md5 ipv6 parport_pc lp parport autofs4 i2c_dev i2c_core sunrpc ipt_REJECT ipt_state ip_conntrack iptable_filter ip_tables dm_multipath button battery ac sd_mod usb_storage scsi_mod uhci_hcd ehci_hcd snd_via82xx snd_ac97_codec snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd_page_alloc snd_mpu401_uart snd_rawmidi snd_seq_device snd soundcore 8139too mii floppy dm_snapshot dm_zero dm_mirror ext3 jbd dm_mod Mar 30 14:53:40 centos01 kernel: CPU: 0 Mar 30 14:53:40 centos01 kernel: EIP: 0060:[<0028f705>] Not tainted VLI Mar 30 14:53:40 centos01 kernel: EFLAGS: 00010206 (2.6.9-67.0.4.EL) Mar 30 14:53:40 centos01 kernel: EIP is at 0x28f705 Mar 30 14:53:40 centos01 kernel: eax: f4360de0 ebx: f4360de0 ecx: 0028f705 edx: e0125fa0 Mar 30 14:53:40 centos01 kernel: esi: 00000145 edi: f634ce00 ebp: 00000003 esp: e0125f48 Mar 30 14:53:40 centos01 kernel: ds: 007b es: 007b ss: 0068 Mar 30 14:53:40 centos01 kernel: Process firefox-bin (pid: 21366, threadinfo=e0125000 task=f4499870) Mar 30 14:53:40 centos01 kernel: Stack: c0182962 e0125f6c 00000009 f634cde0 00000003 e0125fa0 f634cde0 c01829e5 Mar 30 14:53:40 centos01 kernel: e0125f70 e0125fa0 00000000 00000000 f634cde0 0c0e5958 00000009 c0182c09 Mar 30 14:53:40 centos01 kernel: 00000003 00000bb7 f634cde0 f634cde0 00000000 fffffff4 c018201d cd499000 Mar 30 14:53:40 centos01 kernel: Call Trace: Mar 30 14:53:40 centos01 kernel: [<c0182962>] do_pollfd+0x47/0x81 Mar 30 14:53:40 centos01 kernel: [<c01829e5>] do_poll+0x49/0xab Mar 30 14:53:40 centos01 kernel: [<c0182c09>] sys_poll+0x1c2/0x279 Mar 30 14:53:40 centos01 kernel: [<c018201d>] __pollwait+0x0/0x94 Mar 30 14:53:40 centos01 kernel: [<c01291d1>] sys_gettimeofday +0x53/0xac Mar 30 14:53:40 centos01 kernel: [<c031d8eb>] syscall_call+0x7/0xb Mar 30 14:53:40 centos01 kernel: Code: Bad EIP value.

the "official" lightweight desktop environment for CentOS?
by Florin Andrei 31 Mar '08

31 Mar '08

I want to build a dedicated MythTV box using CentOS5. I need a lightweight desktop environment, something extremely simple that does not use much memory. Gnome and KDE use way too much memory and are too complex for what I want to do. The system will login automatically to a certain account after booting up. After the automatic login, it will start immediately the MythTV frontend full-screen. If the frontend dies, the desktop needs to logout / log back in automatically. No other application will run on this machine, only mythfrontend. There will only be one account. Think of it as a single-purpose appliance, not a regular computer. Whatever I use as the desktop environment, it needs to be pretty standard - either included in the distribution proper, or in one of the major repositories. It must be very trivial to enable, with no hacking required to the OS. It must play well with mythfrontend, I don't need any compatibility issues. It must be a stable, reputable software. Which desktop environment would you recommend based on the requirements? -- Florin Andrei http://florin.myip.org/

Weird that it causes the driver module not to load. The original owner suggested that might be the problem so, after trying a CentOS 5.0 kernel and building and trying a 2.6.24.4 kernel I decided to crack the case. I pulled the cable for the case's front audio and mic off the motherboard and tried with that configuration. The good news was I no longer got the error documented in my earlier e-mail but still no sound. The case's front panel audio had two different connectors so I decided to try the other one and suddenly I had sound. No idea what the difference is between the two connectors. What's really strange is both front audio connection jacks are keyed correctly for the front panel audio out on the motherboard. It's just one works and the other doesn't.

Help in troubleshoot cause of high kernel activity
by Noob Centos Admin 30 Mar '08

30 Mar '08

Hi, I had been experiencing a problem on our dedicated server running Centos 5, and unable to successfully track down the problem. Since about 6 days ago, I noticed a spike in load/CPU utilization which went from a typical 0.2x-0.3x to 3.x. At the same time, average traffic also went up and so did the log usage. Prior to this, the server was working fine and there had been no changes to the configuration. Initially, I narrowed it down to the mail system. Exim was generating significantly more log data than usual. This was eventually narrowed down to apparently our server and another server playing ping pong between two users who coincidentally were on vacation and had both their mailboxes filled. Thus it caused an endless loop of "Message Undelivered" and "Auto-reply". Once this was identified and cleared up, I had expected things to go back to normal. However, load/traffic remained high. Looking at "top" output, I noted that %sys was as high and often much higher than %user. However, individual process %CPU just didn't add up to the total top was reporting. Top reports 160~170 sleeping tasks and only 4 active most of the time, which was largely exim then httpd/mysql/php. top Snapshot ========== top - 17:25:03 up 7 days, 19:16, 1 user, load average: 2.03, 2.84, 3.04 Tasks: 168 total, 4 running, 164 sleeping, 0 stopped, 0 zombie Cpu(s): 26.5%us, 50.3%sy, 0.0%ni, 16.6%id, 6.1%wa, 0.0%hi, 0.5%si, 0.0%st Mem: 1915208k total, 1880256k used, 34952k free, 142100k buffers Swap: 16777208k total, 66140k used, 16711068k free, 1276564k cached iostat Snapshot ============ avg-cpu: %user %nice %system %iowait %steal %idle 18.96 0.00 25.57 5.16 0.01 50.30 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn sda 54.19 63.31 2460.80 42689802 1659234904 sdb 55.12 76.41 2460.80 51521720 1659234904 md1 315.95 139.72 2442.00 94207644 1646554216 md0 0.01 0.00 0.02 1422 14736 dm-0 39.13 65.85 292.50 44399402 197219496 dm-1 267.18 36.18 2110.08 24398010 1422756072 dm-2 9.64 37.68 39.42 25408576 26578648 fd0 0.00 0.00 0.00 16 0 sr0 0.00 0.00 0.00 136 0 Searching around for ways to interpret the output, I tried sar/iostat and essentially, the information off the net indicates there wasn't a disk problem, %io was relatively low and mdadm shows the RAID 1 disks working perfectly fine. Since %sys is consistently highest, it appears that the kernel was doing something outside of norm. The problem is I have no idea what else to do to determine what "something" is. I've looked at netstat and there doesn't appear to be excessive connections, logwatch summary also does not appear to give any clue as there are no records of unusual failed log in attempts. Please advise what else can I look into or check. Thanks in advance!

A few questions regarding CentOS (5.0)
by Morten Nilsen 30 Mar '08

30 Mar '08

Hello list, I'm a former Trustix User (were active in that community since the very first betas), and now that my dear distro is dead, I'm looking to make a switch.. Several people recommended CentOS, so I decided to give it a spin.. I installed one new server with 5.0 a few months back, and I do have a couple of questions.. - Why does the screen flicker on and off several times during boot and when logging in? - Why does floppy.so get loaded? I have no floppy, and having floppy.so loaded while installing certain packages is dreadfully slow. - When I chose a pure console environment, without any X11 stuff, why did a bunch of gnome packages get installed? - Is it possible to get a php-mssql package? -I need this if I'm going to use CentOS at work.. I think that's it for now.. -- Cheers, Morten

World Writable Files

I'm curious. Why are so many system-generated files world-writable? On my Mandriva laptop, every day I get warnings that world-writable files are found in /tmp, /far/lib/ /var/run/ and /var/spool, and every day msec reports that it has changed the mode of several files in /var/log/. Why are they created like that? Anne

SSl Certificate problem
by Tom Diehl 30 Mar '08

30 Mar '08

Hi, I have a c4 server that I am trying to migrate an ssl site over to a new C5 machine with all of the updates. The certificate is an equifax cert and works as advertised on the C4 server. When I move it over to the C5 machine I get error in firefox that says error code -12227 which http://www.mozilla.org/projects/security/pki/nss/ref/ssl/sslerr.html says is an SSL_ERROR_HANDSHAKE_FAILURE_ALERT. In addition it says that this means that "SSL peer was unable to negotiate an acceptable set of security parameters." If I try to open the site in IE, it prompts for a client certificate. This fails because I am not using client certs. In the apache config for ssl.conf I have "SSLVerifyClient none". I have also tried setting it to "optional" with the same results. In the past moving these sites to a different machine was as simple as copying the certs and the config files over to the new machine, reloading httpd and everyting just worked. Is there something different about ssl on C5? Does anyone know a good way to troubleshoot this. Google and the docs are not helping. What am I missing?

Hi i have freeradius mschap ldap working configuration - i am using it for pptpd (VPN server) to authentificate against freeradius with ldap . Windows VPN client can connect to our company network and use it. Next i want to add user/password auth to our WIFI (based on Dlink AP - with radius support). We are currently using wpa-preshared key. i want to use wpa enterprise with ldap authentification (providing username and password) without need to install any certificate on windows. First to make a clear - how do i achieve it? --- i mean exactly which protocol i need to use and how it works (some shortcut to such howto) How do i arrange to use same freeradius for currently working VPN and for my plan to make wpa enterprise.

29 Mar '08

Hi there, some of my users use putty to connect to my server via ssh protocol. After some time they get the above error message, and it could be that my CentOS-side configuration caused this. Do anybody has experience with this problem? - Gergely

Cisco PIX vpn software
by Joseph L. Casale 29 Mar '08

29 Mar '08

Anyone got a resource on setting up a CentOS box to connect to a Cisco PIX 5xx VPN using IPSec? I don't know if it matters but an important part of functionality would be split tunneling, I need to maintain that from the windows side of functionality. Thanks! jlc

Yum update erased jdk, jre, and fuse-davfs2
by Robert Moskowitz 29 Mar '08

29 Mar '08

I just did a yum update. It pulled in a number of updates including the latest firefox and davfs2.i386. Then I watch the following show up during the cleanup phase of yum (/var/log/messages): Mar 28 15:42:18 nc2400 Erased: jdk Mar 28 15:42:25 nc2400 Erased: jre Mar 28 15:42:31 nc2400 Erased: fuse-davfs2 Are the first jsut removal of the alternatives? How do I tell and how do I find that message where I got what to do. There were soo many "alternatives" I tried til I got it right...... And something did happen to fuse-davfs2, becuase I now get: /sbin/mount.davfs: can't open fuse device /sbin/mount.davfs: trying coda kernel file system /sbin/mount.davfs: no free coda device to mount BTW, yes, I did reboot after the update.

Sound card problem
by David G. Miller 29 Mar '08

29 Mar '08

I came into an Abit AX8 motherboard and single core AMD Athlon 64 FX. I did a quick install of CentOS 5.0 on it to make sure everything worked and then returned the hard disk and case to the original owner. After getting a new case and hard disk, I downloaded the CentOS 5.1 cd images and installed. For some reason the motherboard's on board sound no longer works (worked with CentOS 5.0). dmesg gives me: ACPI: PCI Interrupt Link [ALKC] enabled at IRQ 22 ACPI: PCI Interrupt 0000:00:11.5[C] -> Link [ALKC] -> GSI 22 (level, low) -> IRQ 90 PCI: Setting latency timer of device 0000:00:11.5 to 64 codec_read: codec 0 is not valid [0x1fc0000] codec_read: codec 0 is not valid [0x1fe0000] codec_ready: codec 0 is not ready [0x1000000] codec_ready: codec 0 is not ready [0x1000000] codec_read: codec 0 is not valid [0x1fc0000] codec_read: codec 0 is not valid [0x1fe0000] AC'97 0 access is not valid [0xffffffff], removing mixer.

Big devices and missing space

questions on kickstart

However with 2 disks present in box it put / on sda and /home on sdb. Is there a way to put it ALL on sda???

Commandline utility to edit ID3 tags?

Hi, I'm running a webradio on our brandnew CentOS 5.1 database server. (The main purpose of this radio is fun, sure, but it's also a bit like a canary in a coalmine...) It's based on Icecast, MPD and NCMPC and works great. I'm configuring the server remotely via SSH, no X. Is there any commandline utility to edit ID3 tags? Cheers, Niki

I have recently attached a USB to my centos 5.1 NAS server. The printer works for about 5 minutes after the box has started but after that it stops working. CUPS says the device is busy. If I print stuff, reboot the server and go into cups it mentions an error about HAL failing, i click start printer anyway and all the documents I have printed will be printed. Someone mentioned it might be USB power saving, if this is the case how do i turn it off? Alan

OpenGL and CAD Apps

I am likely going to switch a desktop over from Windows to either CentOS or Fedora and run two CAD apps that now have Linux ports. I was wondering as I can't seem to find much specific info about the support of OpenGL in RH based OS's. Does CentOS support this out of the box or do I need to do anything with it? Anyone doing this, or know of a definitive resource to point me towards? Thanks! jlc

Deleting file in /tmp directory
by Mário Gamito 28 Mar '08

28 Mar '08

Hi, This is a bit of-topic, but since it has to do with /tmp permissions here it goes. Anyway, I'm sorry in advance for posting this. I have this PHP script (simplificated here), called delete_tmp.php that basically calls external commands: <?php $session_file = '/tmp/sess_89765' system(''rm -f' . ' ' . $session_file); ?> delete_tmp.php file is owned by gamito.users /tmp/sess_89765 file has permissions -rw------ and is owned by gamito.users My /tmp permissions are rwxrwxrwt and is owned by root.root I know that the the sticky bit only allows files to be deleted by their owners, the owner of the directory or by root. Never the less, i can switch to /tmp directory and delete sess_89765 file as user gamito. If I run: $ php delete_tmp.php as root, it deletes sess_89765 file. But if I do the same has user gamito, it doesn't delete the file !!! Ideas ? Any help would be appreciated. Warm Regards, Mário Gamito

Re: [CentOS] Strange behavior from grep
by Mário Gamito 28 Mar '08

28 Mar '08

Hi, Thank you for your answer. After a little more research, I found out that the line containing the word 'gamito' is huge and yet it scrolls so fast in the screen that I can barely see it. I tried redirecting the output of the grep to a file and that huge line went in to it. So, I've tried a double grep: $ grep 'gamito' file | grep 'gamito' but without success. Well, my question now is, how do I get the word 'gamito' alone from the file ? Any help would be appreciated.

Strange behavior from grep
by Mário Gamito 28 Mar '08

28 Mar '08

Hi, It's been a long time since I've been noticing a strange behaviour from CentOS grep command. But today, I really need it. I have a file that has the word gamito inside of it. If I run $ grep 'gamito' file it returns nothing. Yet, if I run $ grep -c 'gamito' file It returns 1 which is right. The mind boggles. Does anyone ever had this problem or am I missing something here ? Any help would be appreciated. Warm Regards, Mário Gamito

Installing Postfix/Dovecot
by Giulio Troccoli 28 Mar '08

28 Mar '08

I have just installed CentOS 5.1 on my home server and I am trying to set a mail server. I have diligently followed the instructions on the Wiki - How To on the CentOS website (http://wiki.centos.org/HowTos/postfix) However I cannot send internal email (I haven't yet tried externally). Do you have any suggestions on what to check? To test it I used two normail user: giulio and federica. I logged in as federica and sent an email to giulio with the mail programme. Is this correct (i.e. using the mail programme)? There is one thing that I don't quite understand from the instructions. In section 3.1 it's suggested to set mynetworks = 192.168.0.0/24, 127.0.0.0/8 in the /etc/postfix/main.cf file. My home network however is 192.168.69.0 and actually the IP assigned to any computers in the networks start from 192.168.69.20. So I changed mynetworks to 192.168.69.0/24 and also 192.168.69.19/30 (as my server IP address is actully 192.168.69.25). I don't think this is the cause of my problem anyway, because it didn't work even with the value suggested by the Wiki page. Thanks for you help Giulio

HTTP blocked?

I just installed CentOS 5 and put ZoneMinder on it. Everything seems to be working fine, except I can't access the web pages from a remote computer, even if it's on the same LAN. If I lynx to the webpage from the server itself the web page comes up. I checked iptables and there doesn't seem to be any block there. There is no firewall within my LAN that would block port 80. Any other ideas? Thanks

new CentOS5.1, samba help requested
by Ray Leventhal 27 Mar '08

27 Mar '08

Hi all, I'm fighting with samba on a new CentOS 5.1 install. The goal here is to have unix/linux usernames/passwords used for the samba shares (which i'll setup using webmin, as I find it easy that way). At present, the home share and one for the company's public share are in place. I can see the server, browsing from WinXP to \\172.16.0.106, but permissions seem amiss. I should be able to read/write to a given share but it seems to be ro. Any pointers or advice would be greatly appreciated. My simple smb.conf file is here: [global] netbios name = BACKUP socket options = TCP_NODELAY force directory mode = 777 unix password sync = yes workgroup = WORKGROUP force create mode = 777 os level = 20 encrypt passwords = yes security = share public = yes passdb backend = smbpasswd directory mode = 777 [homes] writeable = yes public = yes path = /home [company data] comment = company data writeable = yes create mode = 775 path = /home/share1 Thanks in advance, -Ray

portmap not answering
by Kai Schaetzl 27 Mar '08

27 Mar '08

CentOS 5 updated, Xen host. The portmap on this machine is somehow "stuck" and I can't figure out why. I enabled it to be able to mount a remote nfs share. The first hurdle was that "portmap" didn't appear in the chkconfig list, it was installed with the initial packages but not added to chkconfig. Took me a while to figure this out. Adding and starting it up is no problem. But nfs still doesn't work and when I try rpcinfo -p that just hangs until it finally times out after a long while (rpcinfo to another machine is fine). An strace at that time indeed shows that it is stuck trying to connect to port 111 on localhost. Same when I try to connect with telnet. Port 111 shows up on lsof UDP and TCP and there's no error when portmap starts up. There's nothing in iptables or hosts.deny that could prevent a connect. SELinux is permissive. What could block those connects? Kai -- Kai Schätzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com

how do I create a custom CD from an existing CD?
by Rudi Ahlers 27 Mar '08

27 Mar '08

Hi all This may sound funny, but I can't get onto any websites right now, so I can't even google. I want to customize the contents of my CentOS 5.1 x64 CD, and re-create the ISO to write to CD again and install on a server. I know it's got something todo with mkisofs, but I'm not 100% sure what the commands should look like Can someone please give me a sample of the whole command needed for such an operation? -- 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 stugg

Commands failing silently?
by Dan Bongert 27 Mar '08

27 Mar '08

Hello all: I have a couple CentOS 4 servers (all up-to-date) that are having strange command failures. I first noticed this with a perl script that uses lots of system calls. Basically, sometimes a command just won't run: thoth(52) /tmp> ls thoth(53) /tmp> ls thoth(54) /tmp> ls thoth(55) /tmp> ls learner lost+found/ thoth(56) /tmp> ls learner lost+found/ thoth(57) /tmp> ls learner lost+found/ thoth(58) /tmp> ls learner lost+found/ thoth(59) /tmp> ls learner lost+found/ thoth(60) /tmp> ls learner lost+found/ thoth(61) /tmp> ls learner lost+found/ thoth(62) /tmp> ls thoth(63) /tmp> ls thoth(64) /tmp> ls thoth(65) /tmp> ls thoth(66) /tmp> uname -a Linux thoth.ssc.wisc.edu 2.6.9-67.0.7.ELsmp #1 SMP Sat Mar 15 06:54:55 EDT 2008 i686 i686 i386 GNU/Linux Nothing in either dmesg or /var/log/messages seems to indicate any problems. It also doesn't seem to matter what the command is -- ls is the quickest test, but sshd will sometimes to fail to spawn children, etc. There aren't a large amount of processes on the machine either -- only 122 at the moment. Has anyone seen this behavior before? Have I been hit with some sort of cunning rootkit? This machine shouldn't be publicly accessible; it's behind our firewall.

Should I update to DRBD 82?
by Amos Shapira 27 Mar '08

27 Mar '08

Hello, This morning I noticed the following output from "yum update": Installing: drbd82 x86_64 8.2.5-1.el5.centos extras 209 k replacing drbd.x86_64 8.0.11-1.el5.centos As far as I'm aware DRBD works fine for me. Is there a way I can find out about the new release and weather I should upgrade? I can't figure out the CentOS issue tracking system at bugs.centos.org but a google site search came up with http://bugs.centos.org/print_bug_page.php?bug_id=2657 (a DRBD 82 tracker bug with empty reports), which makes me feel like this version of the package is not 100% trusted. So - should I upgrade it or not? Generally, I try to stick to the "standard" as much as I can, but the text in http://wiki.centos.org/Repositories gives an impression that "if it's in Extras, it's well tested". Thanks, --Amos

Anyone still uses "MO drive"?
by Fajar Priyanto 27 Mar '08

27 Mar '08

Hi all, I'm trying to use an old MO drive in Centos5.0. It's connected to an adaptec scsi card. From dmesg, the card seems to be recognized, but it doesn't "create" the sda device from the MO drive. Is there any more steps I must do? From Yahoo search (since it has older archive than google), it seems that Linux should be automatically recognize and setting up the scsi card and the MO drive. So, I'm clueless here. Any pointer is great.

Widescreen monitor with Intel G965 graphics chipset
by Joseph L. Casale 26 Mar '08

26 Mar '08

I just migrated my working Fedora Core 8 desktop to CentOS 5.1 and went from my nice 1680x1050 resolution to 1280x1024. I have made all the possible xorg.conf changes I found on the net to no avail. I tried system-config-display –reconfig and it allows me to pick the resolution but reverts back to 1280x1024 in X? Anyone know what might need to be done in CentOS for this to work? The skewed aspect ratio drives me nuts☺ Thanks! jlc

Two Internet connections...
by Frank Cox 26 Mar '08

26 Mar '08

I do some occasional tech work for a cable TV/Internet service provider. They have now offered me free services, including cable Internet. I currently have a DSL service through the telephone company and, for several reasons including the fact that it is really unlimited service with no cap and it comes with newsgroup access (neither of which the cable service has), I'm not really prepared to give that up. However, since I can get a free cable Internet service too I would like to be able to put that to use. Does anyone have any good ideas for what to do with an extra cable Internet service? Is there, say, a way to somehow "shotgun" two Internet services like you used to be able to do with dial-up modems to increase your transmission speed? -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

After rebooting servers 3 or 4 times that way myself, I now disable this function in /etc/inittab on all of my servers. I don't see any point in allowing a hot-key to reboot a server. -- Bowie
