There is _nothing_ fast about them (see, I > learned how to use the underscore from you, aren't you happy?)... Dude, compared to modern UltraSPARC III/IV, _yes_ they _are_ slow.

Dude, this is _not_ about "winning an argument." It's about reminding you that "build times" are _not_ a good indictator of _server_ benchmark (please note that I said _server_).

Once again, I will re-iterate, there are _other_ performance considerations than computational.

Depends on if you are computationally limited, and also what is your I/O -- let alone the number of sessions you are serving.

It all depends on how distributed your environment works, as well as the application. I'm not saying an old UltraSPARC II platform is always going to be faster. But man, you are like a single track that thinks there are _no_ other considerations. -- Bryan J. Smith mailto:b.j.smith@ieee.org

What do you think about this motherboard?
by Juan Carlos 05 Jul '05

05 Jul '05

Hello all..... I would like to know if anyone here has had good experience with this Supermicro motherboard.....http://supermicro.com/products/motherboard/P4/E7221/P8SCT.c… I am thinking about using it in an entry level mail and file server with a 3ware card and 200 GB SATA drives. Cost is a factor here otherwise I would go for an Opteron board instead. JC

RedHat to CentOS transition
by Matt Jaffe 05 Jul '05

05 Jul '05

I installed RHEL ES 4.0 on a new server because I had the disks. The problem is that the new server does not have a RedHat network subscription and can't use Up2date to keep itself current. We set up a script that just runs apt once a week, but I am curious whether there is some way of changing the box into a CentOS machine and using your Up2Date to get updates from one of the mirrors. I read on the White Box site that they use a Fedora Yum package and a modified version of Up2Date to accomplish the same thing as RedHat's tool. I assume CentOS is the same way. Can I just install those packages and modify the /etc/redhat-release or is there more to it?

NFS sleepy woes
by Res 03 Jul '05

03 Jul '05

Hi all, I have a problem with a CentOS 4 and now updated to 4.1 server, every so often the other servers try to contact it and this not there a retry and it is, like it goes to sleep, I have no problem with the fedora1, RH9 and slackware machines they just never do this. its most annoying.. they all use IP's not names. all access lists are identical, all hosts files are identical, all exports and fstabs are same format. in fact one of the machines on another network altogether reponds instantly. if I reboot *shudder* the CentOS box it fixes it, temporarily, but thats a joke, the hardware is fine, it used to run slackware smoothly, I hope I dont have to go back to it :) TIA

It seems that all of my forms have stopped working using nms FormMail.pl script. Everything was working before these last two updates. I have debug set on the form script and it does work without any errors but I never get the email that a form was submitted. The server company I get my server through did a test on one of the forms and I got the technician's email but when I went to test the very same form I did not get an email. The technician tested from the company so I am thinking this might be some permissions problem with something on my server as the technician would have higher permissions than myself. Another strange occurrence is that whenever a customer of one of my customers on my server submits my client's email form I am getting an email instead of my client showing the details of the form. I have checked all the forms thoroughly and there is nothing wrong with them and since they all were working and now are not working that the problem is with the server itself.

I don't use plesk, but since the form worked for the technician, I would suspect a problem with either name lookups, what IP your mail server is listening on, or your MTA setup. The first thing you need to do is look at /var/log/maillog and see if the messages are making it through the local server and getting to an external server. Any errors, reasons for non delivery, etc. should be in /var/log/maillog or /var/log/messages. I don't even know which MTA plesk uses (sendmail, postfix, etc.) ... but that is where I would start.

Re: Directory Server for CentOS 4.1

From: alex(a)milivojevic.org > I'm abusing the fact that all users have accounts on one of AD domains. Ahhh, so let me get this straight ... Your users are virtual, yet they have real accounts in ADS? Is this just for LAN? Or are you an ISP/ASP? > The "Unix" services are not aware of it. They simply authenticate user > against flat userspace on LDAP server, and the LDAP/saslauthd component > is smart enough to contact appropriate AD domain. Ahhh, a very interesting setup indeed. Are you using ADS because the users are normally logging into Windows? [ And this is a LAN setup, not an ISP/ASP? ] > So, no I'm not using Kerberos as such, because in reallity the clients > users have can't use it either (reason is simple, most Windows software > don't talk neither Kerberos nor SASL - they are all username/password > based with option to pass it over SSL/TLS). Actually, that's not true. You can replaced NT's GINA with pGINA (pluggable GINA) and authenticate and setup your credentials against various authentication/directory services. Unless, of course, you are using software that absolutely requires ADS. > I'm simply abusing the fact I can authenticate against AD domain > using Kerberos as protocol. Correct. Again, I'm curious if this is because you already use ADS for other purposes? Or someone decided that ADS was "easier" to support? > So the question is. If I have user-a and user-b, where user-a exists > as principal user-1@domain-1, and user-b exists as principal user-2 > @domain-2, can I have FDS authenticate the user against appropriate > domain if passed only the "id=user-a,dc=mydomain,dc=com" or > "id=user-b,dc=mydomain,dc=com"? No SASL, no Kerberos mumbo- > jumbo all the way from the user's client software to LDAP server > (what happens between LDAP server onwards can be anything, as > long as it works). It seems so based on the page I sent you. Although I think you might have to change your string slightly. The docs explicitly stated that 1 server _can_ authenticate against _multiple_ realms. I don't see how your setup is different, except for using the MS-Kerberos protocol which has been integrated into newer Kerberos client implementations. -- Bryan J. Smith mailto:b.j.smith@ieee.org

Syslog & charset issues
by Jamie Pratt 03 Jul '05

03 Jul '05

hi, i am running the latest centos 4.1 on a vmware esx server - i'm having an issue where all my iptables output is being echoed to the vmware primary console, yet my syslog conf is the same as on a rh es4 server.. anyone run into this before, or know how to shut the console logging of iptables off alltogether? also, i'm seeing "%2C" in some logs instead of spaces, and man pages have weird characters as well, and all basic env vars are the same between both rh es4 and 4.1, (lang, etc) .. i'm using LANG=en_US.UTF-8 on both. anyone run into this issue either? (I've also seen it on one es3 server before, but it went away with some "up2dates").. thanks, jamie

Loosing mouse pointer on centos 4.1
by Jerry Geis 02 Jul '05

Ok I tried all differnet combinations. gpm off/on etc... restarting gpm when the mouse is lost... nothing helped. This seems to happend when I am running vncviewer. Any other ideas?

If that works, then try disabling GPM and rebooting.

From: Peter Farrow <peter(a)farrows.org> > In one sentence, grub is poorly documented, over complicated pants, and > lilo ROCKS... At the risk of offending even more people by suggesting a "middle ground" where _each_ might actually be applicable more than the other (gasp! not again!): - GRUB is an intelligent boot-loader that is more "dynamic" because it inspects the disk at boot-time, but that requires it have drivers for the disk label (partition table format), slices (filesystems), etc... as appropriate, including introducing geometry issues if GRUB is booting multiple installs, OSes, etc... if the other installs don't agree with GRUB on geometry. - LILO is a dumb, "boot this sector offset" boot-loader, but that means it really doesn't care much for the underlying disk label, slices, geometry, etc... other than some basic disk label editing/modification capabilities (although that does introduce some disk label, slice, geometry, etc... considerations if they are used). Each has own strengths and weaknesses, and should be used accordingly. (BS ducks and awaits his fate in the fallout ;-) -- Bryan J. Smith mailto:b.j.smith@ieee.org
