kernel issues
by William Warren 03 Mar '07

03 Mar '07

I just had to revert from the latest kernel back to .08 due to panics. i used rpm to remove the .10 kernel. However i know can't get the smp version of the .10 kernel to install via yum. What am i missing? -- My "Foundation" verse: Isa 54:17 No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn.

RE: [CentOS] Virtualisation
by Mark Hull-Richter 02 Mar '07

How memory-intensive is VMWare workstation? I have a P4 3.0GHz with 1/2Gb of memory at home - is VMWare going to be a total drag on the system or is it lightweight enough that I can still run (as opposed to walk or crawl)? I run VMWW at work, but that's a Pentium-D with 2Gb of RAM, and top shows vmware using 199m virt, 1.1g res and 1.1g shr - not sure what that means (but it looks like bad news for the home situation...). Thanks.

errors

for most of you this is going to be simple for me it's new: I have a ssytem that suddenly throws this error after the most recent kernel upgrade: http://img172.imageshack.us/my.php?image=errordh4.jpg I'm thinking i should be able to back the sytem off to the previous kernel. How do i do this since it won't boot? -- My "Foundation" verse: Isa 54:17 No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn.

Re: [CentOS] What is cached swap?
by C. Halstead 02 Mar '07

02 Mar '07

That number is the amount of physical memory that is being used by cache buffers for your filesystems. It has nothing to do with swap. Try this trick: Run top and note the value of 'cached' run 'dd if=/dev/zero of=~/test bs=1M count=256' Run top again and see that 'cached' has grown by 256M remove the file ~/test Run top again and see that the value of 'cached' has dropped by 256M With that said, there is a 'SwapCached' value reported in /proc/meminfo that represents the amount of swap space used by pages that are also in physical mem (like if something was swapped out and then back in). The VMM doesn't clear those swap pages unless they are needed or the process terminates. Cheers, -chris --- C.

setting up incoming PPP on centos 4.4
by fredex 02 Mar '07

02 Mar '07

hi gang! I'm interested in setting up incoming PPP on a system at work that has a fresh (not upgrade) Centos 4.4 on it. All the documentation I've found for that shows using mgetty to do it, and seems pretty straightforward. However, that machine doesn't have a binary named mgetty anywhere. It does have a mgetty-sendfax RPM installed, but it does not provide a binary named mgetty. "yum -list available | grep -y getty" shows no additional packages I could use to obtain it. so, how does one set up incoming PPP on Centos 4.4? (I've searched the RH knowledgebase and all I found there that came close was a very nice document on doing it on RHEL 3, which shows how to do it with mgetty. Catch 22.) Thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- The eyes of the Lord are everywhere, keeping watch on the wicked and the good. ----------------------------- Proverbs 15:3 (niv) -----------------------------

Off-topic: Howto decrypt OpenSSL file in Win32 environment
by Jordi Espasa Clofent 02 Mar '07

02 Mar '07

Hi all, I supose the subject is descriptive enough. In a CentOS server I do the next to make the daily backups: tar cfv - dir_data/ | openssl enc -e -salt -aes256 -pass pass:$PASSWORD -out backup_file.bin So I get an well-encrypted and tared file. If I want to decrypt and the file is easy in Unix/Linux environment: openssl enc -d -aes256 -in backup_file.bin | tar xfv - -C dir_what_you_want/ But the problem I currently have is I don't know how to make it in Win environment. ?¿?

Storage/SCSI Error on our CentOS server
by Hairul Ikmal Mohamad Fuzi 02 Mar '07

02 Mar '07

Hi, Currently we are running CentOS 4.x on a 2-way Opteron machine. This machine, through a SCSI host adapter (Adaptec), is connected to a 2TB storage unit (an external RAID-5 disk array) Until our recent unintentional power trip, everything was fine and smooth. We have been experiencing complication accessing the storage ( it could be either intermittent filesystem error, partition could not be mounted in read-write mode, unacceptable writing speed, etc ), especially when we start to 'write' on the storage. After a few check, we are suspecting either : 1) the storage unit (but the storage control panel did not report any disk/raidset failure) is failing or, 2) the SCSI host adapter is failing, or 3) the filesystem itself is corrupted (we did 'fsck.ext3 -v -f' but it turned out it did not find any errors) ..but we are not sure which one.We did received 'messages' which we never experience previously in our 'dmesg' . (please refer below) Based on the above info and the below 'dmesg' output, we'd appreciate if somebody could share and help us to identify what actually went wrong and how could fix it (if possible)? TIA. -Ikmal Dmesg output : =========================================== scsi4:0:0:0: Attempting to abort cmd 0000010082297a80: 0x28 0x0 0x0 0x0 0x1 0x3f 0x0 0x0 0x8 0x0 scsi4: At time of recovery, card was not paused >>>>>>>>>>>>>>>>>> Dump Card State Begins <<<<<<<<<<<<<<<<< scsi4: Dumping Card State at program address 0xc Mode 0x33 Card was paused HS_MAILBOX[0x0] INTCTL[0x80] SEQINTSTAT[0x0] SAVED_MODE[0x11] DFFSTAT[0x33] SCSISIGI[0x0] SCSIPHASE[0x0] SCSIBUS[0x0] LASTPHASE[0x1] SCSISEQ0[0x0] SCSISEQ1[0x12] SEQCTL0[0x0] SEQINTCTL[0x0] SEQ_FLAGS[0xc0] SEQ_FLAGS2[0x0] SSTAT0[0x0] SSTAT1[0x0] SSTAT2[0x0] SSTAT3[0x0] PERRDIAG[0xc0] SIMODE1[0xa4] LQISTAT0[0x0] LQISTAT1[0x0] LQISTAT2[0x0] LQOSTAT0[0x0] LQOSTAT1[0x0] LQOSTAT2[0x0] SCB Count = 4 CMDS_PENDING = 1 LASTSCB 0xffff CURRSCB 0x2 NEXTSCB 0x0 qinstart = 59 qinfifonext = 59 QINFIFO: WAITING_TID_QUEUES: Pending list: 2 FIFO_USE[0x0] SCB_CONTROL[0x64] SCB_SCSIID[0x7] Total 1 Kernel Free SCB list: 3 1 0 Sequencer Complete DMA-inprog list: Sequencer Complete list: Sequencer DMA-Up and Complete list: scsi4: FIFO0 Free, LONGJMP == 0x80ff, SCB 0x0 SEQIMODE[0x3f] SEQINTSRC[0x0] DFCNTRL[0x0] DFSTATUS[0x89] SG_CACHE_SHADOW[0x2] SG_STATE[0x0] DFFSXFRCTL[0x0] SOFFCNT[0x0] MDFFSTAT[0x5] SHADDR = 0x00, SHCNT = 0x0 HADDR = 0x00, HCNT = 0x0 CCSGCTL[0x10] scsi4: FIFO1 Free, LONGJMP == 0x81d8, SCB 0x3 SEQIMODE[0x3f] SEQINTSRC[0x0] DFCNTRL[0x0] DFSTATUS[0x89] SG_CACHE_SHADOW[0x2] SG_STATE[0x0] DFFSXFRCTL[0x0] SOFFCNT[0x0] MDFFSTAT[0x5] SHADDR = 0x00, SHCNT = 0x0 HADDR = 0x00, HCNT = 0x0 CCSGCTL[0x10] LQIN: 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 scsi4: LQISTATE = 0x0, LQOSTATE = 0x0, OPTIONMODE = 0x52 scsi4: OS_SPACE_CNT = 0x20 MAXCMDCNT = 0x0 SIMODE0[0xc] CCSCBCTL[0x0] scsi4: REG0 == 0xffff, SINDEX = 0x1e0, DINDEX = 0xe1 scsi4: SCBPTR == 0x3, SCB_NEXT == 0x2, SCB_NEXT2 == 0x2 CDB 28 0 0 80 19 ac STACK: 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 <<<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>> DevQ(0:0:0): 0 waiting (scsi4:A:0:0): Device is disconnected, re-queuing SCB Recovery code sleeping Recovery SCB completes Recovery code awake scsi4: Transmission error detected LQISTAT1[0x0] LASTPHASE[0x1] SCSISIGI[0x0] PERRDIAG[0x1] >>>>>>>>>>>>>>>>>> Dump Card State Begins <<<<<<<<<<<<<<<<< scsi4: Dumping Card State at program address 0x26 Mode 0x11 Card was paused HS_MAILBOX[0x0] INTCTL[0x80] SEQINTSTAT[0x0] SAVED_MODE[0x11] DFFSTAT[0x33] SCSISIGI[0x1a] SCSIPHASE[0x1] SCSIBUS[0xff] LASTPHASE[0x1] SCSISEQ0[0x40] SCSISEQ1[0x12] SEQCTL0[0x0] SEQINTCTL[0x0] SEQ_FLAGS[0xc0] SEQ_FLAGS2[0x0] SSTAT0[0x10] SSTAT1[0x11] SSTAT2[0x0] SSTAT3[0x0] PERRDIAG[0x0] SIMODE1[0xac] LQISTAT0[0x0] LQISTAT1[0x0] LQISTAT2[0x0] LQOSTAT0[0x0] LQOSTAT1[0x0] LQOSTAT2[0x0] SCB Count = 4 CMDS_PENDING = 1 LASTSCB 0xffff CURRSCB 0x2 NEXTSCB 0x0 qinstart = 61 qinfifonext = 61 QINFIFO: WAITING_TID_QUEUES: 0 ( 0x2 ) Pending list: 2 FIFO_USE[0x0] SCB_CONTROL[0x50] SCB_SCSIID[0x7] Total 1 Kernel Free SCB list: 3 1 0 Sequencer Complete DMA-inprog list: Sequencer Complete list: Sequencer DMA-Up and Complete list: scsi4: FIFO0 Free, LONGJMP == 0x80ff, SCB 0x0 SEQIMODE[0x3f] SEQINTSRC[0x0] DFCNTRL[0x0] DFSTATUS[0x89] SG_CACHE_SHADOW[0x2] SG_STATE[0x0] DFFSXFRCTL[0x0] SOFFCNT[0x1] MDFFSTAT[0x5] SHADDR = 0x00, SHCNT = 0x0 HADDR = 0x00, HCNT = 0x0 CCSGCTL[0x10] scsi4: FIFO1 Free, LONGJMP == 0x81d8, SCB 0x3 SEQIMODE[0x3f] SEQINTSRC[0x0] DFCNTRL[0x0] DFSTATUS[0x89] SG_CACHE_SHADOW[0x2] SG_STATE[0x0] DFFSXFRCTL[0x0] SOFFCNT[0x1] MDFFSTAT[0x5] SHADDR = 0x00, SHCNT = 0x0 HADDR = 0x00, HCNT = 0x0 CCSGCTL[0x10] LQIN: 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 scsi4: LQISTATE = 0x0, LQOSTATE = 0x0, OPTIONMODE = 0x52 scsi4: OS_SPACE_CNT = 0x20 MAXCMDCNT = 0x0 SIMODE0[0xc] CCSCBCTL[0x4] scsi4: REG0 == 0x3, SINDEX = 0x11d, DINDEX = 0xe1 scsi4: SCBPTR == 0x3, SCB_NEXT == 0x2, SCB_NEXT2 == 0x2 CDB 28 0 0 80 19 ac STACK: 0x13 0x0 0x0 0x0 0x0 0x0 0x0 0x0 <<<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>> DevQ(0:0:0): 0 waiting (scsi4:A:0): 80.000MB/s transfers (40.000MHz DT, 16bit) ===========================================

Hi Friends, I am trying to run vnc on port 8080 on Centos 3.4 . There are no kde or gdm packages installed as we only need xserver. I have installed XFree86-font-utils-4.3.0-78.EL XFree86-75dpi-fonts-4.3.0-78.EL XFree86-base-fonts-4.3.0-78.EL XFree86-xdm-4.3.0-78.EL XFree86-libs-data-4.3.0-78.EL XFree86-4.3.0-78.EL XFree86-libs-4.3.0-78.EL XFree86-xfs-4.3.0-78.EL XFree86-Mesa-libGL-4.3.0-78.EL XFree86-xauth-4.3.0-78.EL XFree86-truetype-fonts-4.3.0-78.EL XFree86-Mesa-libGLU-4.3.0-78.EL XFree86-100dpi-fonts-4.3.0-78.EL vnc vnc-server and I want to run vnc only one for 1 user but with multipe client connections. Plesae guide me how to configure VNC to run on port 8080 and for only 1 user. Thanks & Regards Ankush Grover
