kernels and irc
by James Bunnell 06 Jun '08

06 Jun '08

I was in the #centos-social channel and simply stated that I noticed CentOS 3-4 were getting a lot of updates. I also stated that the CentOS 5 was one kernel behind, as in RHEL it is at -53, the gentlemen then told me that I was wrong and it was at -21. I then asked if there was a way to get a progress report somehow on 5.2, and that 5.2 has already upgraded that kernel. The result was that I was banned for being correct. I dont understand this kind of support.

firewalled NFS
by Jordi Prats 06 Jun '08

06 Jun '08

Hi, I'm trying to setup a firewalled NFS server. I've configured my server (CentOS 5) using the following parameters /etc/sysconfig/nfs MOUNTD_NFS_V1="no" MOUNTD_NFS_V2="no" RQUOTAD_PORT=875 LOCKD_TCPPORT=32803 LOCKD_UDPPORT=32769 RPCNFSDCOUNT=64 MOUNTD_PORT=892 STATD_PORT=662 STATD_OUTGOING_PORT=2020 SECURE_NFS="yes" modprobe.conf: options lockd nlm_udpport=4001 nlm_tcpport=4001 But it does not mount it: # mount 172.20.0.150:/tmp/ /mnt/tmp/ mount: mount to NFS server '172.20.0.150' failed: timed out (giving up). There's anything else I must setup to use fixed ports ? Thanks, -- Jordi

Hi I just grabbed an 8gig thumb drive, took disk 1 centos 4 i386, copied the isolinux directory files to my thumbdrive, then ran syslinux -sf /dev/sdc1 on the device plugged it into my laptop and it does not boot. Is there a step(s) I am missing to get a bootable thumbdrive with centos? Thanks, Jerry

OT - colors in window change - sometimes....
by MHR 06 Jun '08

06 Jun '08

One of our Windows machines here has this interesting property that I could not duplicate in Linux (F8, but I'll check it later at home from C5.1, too). If I open a DOS window, set the properties to have a white background with dark blue font, telnet to another machine, and run some commands, sometimes the commands echo in gray on black (and stay that way). For example, the default ls (which has the color=tty option set), does this, but only with what it prints to the screen. The real killer is vi, which resets the whole screen background back to black with colored fonts, some of which are really hard to read (like dark blue on black - egad!). When I log out, the DOS window resets, but only what it prints, unless I clear the screen, which "fixes" it. Does anyone know anything about this? Seems really strange (like most WinDO$ weirdness). NEVER happens on my Linux box, but it does happen through rdesktop.... Thanks. mhr

kernel compile for i586
by Jerry Geis 05 Jun '08

05 Jun '08

I created a i586 install image with qemu. I downloaded the SRPMS package for the kernel and installed it. I cd /usr/src/redhat/SPECS rpmbuild -bp --target i586 kernelXXX.spec I does a bunch of things but it did not build a new kernel and put it in /boot I think I am missing a command to actually BUILD the kernel. What is it? Thanks, Jerry

tcp_tw_recycle / tcp_tw_reuse
by nate 05 Jun '08

05 Jun '08

Anyone have experience with these kernel parameters? I can't find a whole lot of info on them. I have a situation where I'm trying to stress test a server, dual proc quad core with a tomcat application that is really fast. We can get it to about 60% CPU usage, and processing about 1,350 requests a second but we can't get much past that. It seems we are maxing out the sockets on the system, with more than 60,000 connections in TIME_WAIT. Our requests are really small and light and short lived. So I was thinking of using these parameters to get more out of the tcp stack. Our load balancer is configured to terminate connections to the world after 25 seconds(a typical request takes 0.1 seconds to complete), but I'm not sure if that applies to the systems behind the load balancer as well(I suspect not because there's no apparent setting for that). Currently I have the system configured to take a lower amount of traffic, hovering at around 47% CPU, at around 833 req/s and it has 43k connections in these states: #### state ------------------ 65 CLOSING 94 ESTABLISHED 172 FIN_WAIT1 50 FIN_WAIT2 10 LAST_ACK 497 SYN_RECV 43480 TIME_WAIT On a side note, the 'active tcp sockets' reported by sar seems wildly inaccurate, it reports only ~10 active tcp sockets, it barely varies from the system being idle to the system being maxxed out. The docs I can find says seek expert assistance..any experts reading this ? Running CentOS 4.6 thanks nate

ok..i can install dovecot+postfix+MYSQL..etc..and maybe the problem it's resolve. i don't have problem with the machines, the machines are goods, my problem is the tranparent receive e-mails to the users than are distributed in four machines with the same number the users and different users in each. as does google??. they have one entry to e-mail system (gmail.com) but they have several machine (maybe thousands) in transparent mode. i read something like LVS...some comment about this software..! is my solution or I'm lost?

rpm -q versus what's installed
by Scott R. Ehrlich 05 Jun '08

05 Jun '08

I am trying to install Oracle client 10g (10.2.0) on a 64-bit CentOS 5.0 system. 'rpm -q make gcc glibc etc' reveals some packages as "not installed", yet a yum install <package name> consistently returns Nothing to do. Yum list available <package name> yields nothing needed. If rpm -q <list of packages> lists some that are "not installed" but every variant of yum install and yum list I've tried and googled claiims nothing more needs to be installed, either the OS is misreporting (I doubt that) or I'm missing something that is not easily being revealed, or that I haven't used in a long time and outright forgetting. I still need (per rpm -q): compat-gcc compat-gcc-c++ compat-libstsdc++-devel openmotif21 gnome-libs There has been a suggestion of the version of Oracle (32 or 64 bit) I'm trying to install, but after thinking about it, I believe this question is a more fundamental operating system issue. Thanks for any insight. Scott
