Openoffice.org quick launcher
by Jordi Espasa Clofent 01 Mar '07

Hi all, I know it's a dummy question, but ¿where is the gnome's quick launcher for OpenOffice.org suite? I search in several repos under their common name (ooqstart-gnome) without any result. ¿Where is it or what is the package's name? Thanks.

Kernel panic (2.4.21-47)
by Juha Heljoranta 01 Mar '07

01 Mar '07

Hi, We have a server which seems to panic once a while. I was wondering does the stack trace make any sense to you. The server usually runs a week or more and then crashes. Here is all what we had on the server screen when it crashed (hope I didn't make any typos): CPU: 0 EIP: 0060:[<c0168380>] Not tainted EFLAGS: 00010297 EIP: is at do_pollfd [kernel] 0x20 (2.4.-47.EL/i686) eax: 00000001 ebx: 00000000 ecx: 00000286 edx: f7e18600 esi: b8000070 edi: 00000000 ebp: 00000000 esp: d5dbff1c ds: 0068 es: 0068 ss: 0068 Process java (pid: 20490, stackpage=d5dbf000) Stack: c012c000 00000000 00000000 99c87d00 00000000 00000000 c01684ff 00000001 b8000070 d5dbff50 d5dbff54 d5dbe000 d5dbe000 00000000 00000000 00000001 99c87d00 00000000 00000001 c01686e7 00000001 00000000 00000001 f7e18600 Call Trace: [<c012c000>] process_timeout [kernel] 0x0 (0xd5dbff1c) [<c01684ff>] do_pollfd [kernel] 0x19f (0xd5dbff34) [<c01686e7>] sys_poll [kernel] 0x1d7 (0xd5dbff68) [<c01269ab>] sys_gettimeofday [kernel] 0x3b (0xd5dbff9c) [<c028406f>] no_timing [kernel] 0x7 (0xd5dbffc0) [<c028002b>] compress_block [kernel] 0x6b (0xd5dbffe0) Code 8b 06 31 db 85 c0 78 47 e8 03 e1 fe ff 85 c0 89 c7 bb 20 00 Kernel panic: Fatal exception

SMP on a HP DL-320 G2
by fredex 01 Mar '07

01 Mar '07

Hi gang! At work I have a DL320 G2 machine I use as my desktop (I know, weird!...). Back when I ran RHEL WS 2.1 on it, it always ran a SMP kernel because it has a HypterThread capable processor. When I installed (fresh from scratch) Centos 4.4 on it a while back, though, Centos installed only the UP kernel. I've looked in the BIOS for settings to enable/disable HT support and I don't see anything. I've force-installed the SMP kernel and when I boot it it doesn't seem to think there's anything thre but a normal UP CPU. Should it not show two CPUs in top, and in suitable places in /proc like the earlier OS did? (at least when running a SMP kernel) Ideas welcome. Thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. ------------------------------- Romans 5:8 (niv) ------------------------------

Help with XDMCP over SSH
by Plant, Dean 01 Mar '07

01 Mar '07

I am trying to get XDMCP working over SSH on CentOS 4.4 from a windoze box running Cygwin/Putty I have set Enable=true in /etc/X11/gdm/gdm.conf restarted the X server, logged in with Putty and X11 forwarding enabled. I then try to start the Xserver with the following commands # gdmXnestchooser localhost or # Xnest :1 -query localhost Both commands will successfully display a X window and show the X mouse pointer but not the chooser. Can anyone tell me what I am doing wrong? Thanks Dean

On PostScript
by James B. Byrne 01 Mar '07

01 Mar '07

I have been attempting to create a custom fax cover sheet for a hylafax web front end called avantfax. It requires as input an encapsulated postscript file conaining the glyph definitions and the text to be subsituted as strings having the form XXXX-to-variable or XXXX-from-variable. I have been trying to create a valid eps file using a varitiy of methods with no great succes. However, I ahve uncovered a few bits of information from my explorations and I wonder if someone here with greater postscript exprience than I might help: What am getting from printing to a file using an applewritter ppd is this: ---> snip %%Page: 1 1 %%PageBoundingBox: 0 0 612 792 %%BeginPageSetup % [{ %%BeginFeature: *PageSize Letter <</PageSize[612 792]/ImagingBBox null>>setpagedevice %%EndFeature } stopped cleartomark %%EndPageSetup gsave [0.24 0 0 -0.24 0 792] concat gsave 237 278 moveto 0 setgray (Courier-iso1252) cvn findfont 50 -50 matrix scale makefont setfont <585858582D746F2D6661782D6E756D626572> [30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 0] xshow grestore grestore showpage %%PageTrailer %%Trailer %%BoundingBox: 0 0 612 792 %%Pages: 1 <--- What this tells me is that the string that I wish to use is bounded by the <> characters and are present as a set of array indices. So 58 (hex) maps to the 98 entry of the array and this gives the letter /X. 2D likewise maps to 46 and this is /hyphen. 74 maps to index 116 and this is letter /t and so on. The problem is that the application software is looking to replace the sting "XXXX-to-fax-number" and not <585858582D746F2D6661782D6E756D626572>. Is there an alternative form of prepresentation within an eps document to display using the actual ascii text and not use these lookups? I have noted that when documents are created using Acrobat that I get different commands that use ASCII text strings, but that these are broken in arpitratry places (presumably to allow expact glyph positioning on the image irrespective of font metrics on the target device). What I want to have in the final .ps file is something approximating this: ---> (Courier-iso1252) cvn findfont 50 -50 matrix scale makefont setfont "XXXX-to-fax-number" [30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 0] xshow <--- Regards, -- James B.

RE: [CentOS] How to build a debug kernel
by Mark Hull-Richter 28 Feb '07

Not sure - I'm still pretty new to RHEL and its construction. Does that provide enough info for gdb to look through the kernel and set breakpoints, etc.? If so, that should be good enough.... > -----Original Message----- > From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On > Behalf Of Jim Perrin > Sent: Wednesday, February 28, 2007 2:41 PM > To: CentOS mailing list > Subject: Re: [CentOS] How to build a debug kernel > > When you build, you get the kernel debuginfo package.

How to build a debug kernel
by Mark Hull-Richter 28 Feb '07

28 Feb '07

I need to build a kernel with full debugging enabled - breakpoints, etc. I know there's a relatively simple way to do this with rpms, but I don't know what it is.... Help? Thanks.
