Severe VMware slowdown
by Mark Hull-Richter 29 Nov '07

29 Nov '07

In the last few days, I have noticed a drastic slowdown in my VMware Windows guest OS.. I recently bit the bullet and upgraded it from XP SP1 to SP2, and that seemed to work fine for quite a few days. The two major changes I made to the system recently were: 1) The most recent update from CentOS (can't remember which one, but it was within the last two weekd for 5.0). 2) Adding another VM guest OS, this one a CentOS 5.0 guest. What happens is, usually when I click the mouse in the Windows window, the system hangs up completely for some period of time that usually exceeds four minutes. Thereafter, once the VM is "running," it will occasionally just stop when I am transitioning into the VM from elsewhere. I verified this using the CentOS system clock - last night it stopped at 23:01 and still read 23:01 when my cell phone, which is usually dead on in sync with the system clock, read 11:04pm. I cut back on the amount of memory allowed to the Windows VM (768MB, down from 1GB) and that seemed to help a little, but I have 2GB and I'm thinking that this should not be a problem. Any input would be helpful. Thanks. mhr P.S.: Now I'm thinking that my earlier remark about applications was a bit overstated....

For reasons I'd rather not go into, I need to get CentOS 3.anything on a Dell T3400: http://www.dell.com/content/products/productdetails.aspx/precn_t3400?c=us&l… The hard drive is not seen at install time. Can someone point me in the right direction to see if this is possible and how to proceed? Regards, -mark

Installing HP Color Laserjet 3500 printer in CentOS 5
by Andrew Allen 29 Nov '07

29 Nov '07

OK, I've downloaded and installed the driver (pxljr-1.1-1.i386.rpm), and the ppd file (HP-Color_LaserJet_3550-pxljr.ppd) in /etc/cups/ppd. Now I'm trying to set up the printer, connected to the network via a JetDirect printer server at location 192.168.0.200. Trouble is, I'm really not sure about all the settings in Printer Configuration - specifically, what should the Device URI be - at the moment, it says socket://HPColourLaserjet3500:9100, but I'm not sure if this is correct, but it doesn't seem to be because it won't print a test page. Any help much appreciated, Thanks, Andy

Adobe products under Linux?
by Scott Ehrlich 29 Nov '07

29 Nov '07

Also sent to Codeweavers - [what is this list's insights?] I have a 32 GB, dual quad-core desktop machine and was considering 32-bit Windows XP w/SP2, but discovered it only supports up to 4 GB RAM, so that idea is shot. Next in line is 64-bit CentOS 5. The major need for Windows would be very active use of Adobe Acrobat 8, Photoshop CS3, and Illustrator CS3. There may also be the need to copy/transfer information among Matlab, Mathematica, and Microsoft-based applications, from Office 2003 to the above-mentioned ones. Do you support these, and how complete is your product line for 64-bit CentOS 5? Based on your answer, I'll know whether to go with a virtual machine-based solution, which means a Windows VM, or can remain Linux-only, with your solution. Thank you very much. Scott

libgd question on CentOS (in order to get PerfParse working with Nagios)
by Rogelio 29 Nov '07

29 Nov '07

Do I have the necessary gd packages installed on my CentOS 4 box? rpm -qa | grep gd gdk-pixbuf-0.22.0-17.el4.3 gdk-pixbuf-devel-0.22.0-17.el4.3 gdbm-1.8.0-24 gdbm-devel-1.8.0-24 gd-devel-2.0.28-5.4E gd-2.0.28-5.4E gdm-2.6.0.5-7.rhel4.15 sysklogd-1.4.1-26_EL I'm trying to install PerfParser (./compile->make && make install), but I'm getting a "gImageString error", which according to this FAQ (http://perfparse.de/tiki-view_faq.php?faqId=1) means: "The gd library is probably not installed yet on your system. Or you are missing the development package such as libgd-devel or libgd-dev." I "yum search" 'd for libdg and found the following. Is this what I install? libgdiplus.i386 1.0.5-1.2.el4.rf rpmforge Matched from: libgdiplus libgdiplus is an Open Source implementation of the GDI+ API, it is part of the Mono Project libgdiplus-devel.i386 1.0.5-1.2.el4.rf rpmforge Matched from: libgdiplus-devel Header files, libraries and development documentation for libgdiplus This package contains the header files, static libraries and development documentation for libgdiplus. If you like to develop programs using libgdiplus, you will need to install libgdiplus-devel.

mod_gnutls on Centos 4
by David Hrbáč 29 Nov '07

29 Nov '07

Hi, as you might know I have created mod_gnutls for CentOS4 a few months ago. http://fs12.vsb.cz/hrb33/el4/hrb/stable/i386/RPMS/repodata/repoview/mod_gnu… http://fs12.vsb.cz/hrb33/el4/hrb/stable/i386/RPMS/repodata/repoview/gnutls-… http://fs12.vsb.cz/hrb33/el4/hrb/stable/i386/RPMS/repodata/repoview/gnutls-… http://fs12.vsb.cz/hrb33/el4/hrb/stable/i386/RPMS/repodata/repoview/gnutls-… I'd like to ask if someone is using it? It seems to me that it's not able to handle higher load. When user hits F5 there are a few httpd processes running the full cpu. Strace shows nothing, server-status marks them "reading". :o( It seems to me that when user breaks/stops the request httpd breaks. Any experiences? Thanks, David

Help with file descriptor
by Guy Boisvert 29 Nov '07

29 Nov '07

Hi all! I have a problem with CentOS 4.4 and Communigate Pro 5.0.9. As our user number grows, we are seeing "too many files open" error messages in Communigate logs. I spoke with Communigate tech support and they asked me to increase the number of file descriptors which i did. I put 128000 as a script i made to check Communigate open files reported as high as 99000. As i checked the Communigate log file, it reported that it "sees" 1024 "available" file descriptors. Reporting that to Communigate tech support, the guy answered: "CommuniGate gets this number via getdtablesize() system call. Probably in CentOS the table has a fixed size so you need to recompile the kernel to expand it. Try upgrading CentOS to 4.5 (or whatever later version is available) " I'm a little afraid of upgrading the server right away, i don't want to worsen the problem. Or maybe it's safe to do it. I dunno. Is there anybody on the list that can comment on what the Communigate tech support guy said about the "getdtablesize" thing ? Thanks in advance! Guy Boisvert
