Does anybody know of a tool for windows that will let me work with DosFS filesystems (ie: add and remove files, format a flash card with DosFS, etc? Failing that, if there's something for mounting one under linux, I could deal with that as well. I understand DosFS is close in some ways to a DOS filesystem (naming conventions and whatnot), But it's obviously different in other ways, since when I stick the CF card containing the filesystem in a windows PC, it sees files on it, but the names are garbage and the sizes are incorrect. Any ideas? Thanks in advance.

- 1. Running RTP module
Hi all, I am ryinh to run small HelloWorld.vxe , on Vxworks 6.5. I have configured kernel with RTP support package has mention in document. But while running i am getting following message Launching Process "HelloWorld.vxe" rtp exec : the process 'HelloWorld.vxe' ends abnormally plz suggest with regards sharath - 2. Memory overflow problems
Hi Folks, On target systems which doesn't support MMU, no memory protection is provided which leads to nasty bugs if there is a buffer overflow or stack overflow. There is no exception like segmentation fault etc. on Linux ruuning on MMU target. With a core dump we can trace the chain of calls leading to the actual problem. How does one go about debugging such problems in VxWorks bcos the problem is at one place and the crash happens elsewhere ! Appreciate your help. Thanks, syuga - 3. Reset TCPIP stack
Is there any way to restart VxWorks TCPIP stack? Our VxWorks device hung couple times under load and it happened while this system was under heavy TCPIP load (we check mbufs statistics periodically). We want to provide a workaround - restart the IP stack (if possible) every time we see this symptom (the system is running out of mbufs). It doesn't happen too often, so such a workaround will be acceptable. Thanks in advance. - 4. shared memory between RTP app and Kernel Module
I am using vxworks 6.5, for PPC board. I want to use shared memory between kernel module app and RTP app. I am not able to use "shm_open" etc(POSIX calls) in kernel module. How can i use it? - 5. Symbolic links in vxWorks
Hi All, Could you please tell me how to create symbolic links in vxWorks? ln - s (unix command for creating symbolic link) is not supported in vxWorks. I tried to use symlink() , that also didnt work. Thanks in advance Anil

It depends on how you have formatted the CF card. If it is formatted with 8.3 format, it would be fine. Only the VX_LONG_NAME (don't have docs, hope you grok) would make it incompatible to be read on a PC. If you are an end user, you may not have an option. If you are developing on vxWorks/DosFs and this criteria is important, then don't format with VX_LONG_NAME. Most likely if you are an end user, you could format the card on Dos/Windows and then use it with vxWorks. I doubt the device would reformat it (but anything can happen). Also Leonid (the developer of DosFs) has suggested that it is much more realiable to use the 8.3 naming convention. With regular DOS, there is an allocation table, a directory table and file data. Using an extended naming scheme adds a fourth element. There were synchronization/reliablity issues when using extended names. I did some extensive testing with random resets and the 8.3 was much more reliable. I did get failures that were related to TFFS ( < .5 %), but you are using CF... fwiw, Bill Pringlemeir. -- Windows programmer - every problem solved with a switch statement. vxWorks FAQ, " http://www.**--****.com/ ~borkhuis/vxworks/vxworks.html"

Under unixware 714 MP4 I have a usb mounted dosfs drive (/mnt/lacie/). When I cp or mv files with more than one extension it appears to copy 2 copies of the file, one with the original name of the file and one with a dos 8.3 name invented by the system. I thought at first it was just 2 names pointing to the same data but they can independently deleted. It gets weirder - notice the timestamp on the 8.3 file after the second copy. The file name changes but the timestamp doesn't! # ls /mnt/lacie/LMT # cp 00000013.tar.Z* /mnt/lacie/LMT # ls /mnt/lacie/LMT 00000013.tar.Zaa 000000~1.ZAA # touch x.y.z.p # mv -f x.y.z.p /mnt/lacie/LMT # ls /mnt/lacie/LMT 00000013.tar.Zaa 000000~1.ZAA XYZ~1.P x.y.z.p # rm /mnt/lacie/LMT/000000~1.ZAA # ls /mnt/lacie/LMT 00000013.tar.Zaa XYZ~1.P x.y.z.p # ls -l /mnt/lacie/LMT total 566 -rwxrwxrwx 1 root root 9272296 Dec 21 11:23 00000013.tar.Zaa -rwxrwxrwx 1 root root 0 Dec 21 11:25 XYZ~1.P -rwxrwxrwx 1 root root 0 Dec 21 11:24 x.y.z.p # touch x.y.z.p # mv -f x.y.z.p /mnt/lacie/LMT # ls -l /mnt/lacie/LMT total 566 -rwxrwxrwx 1 root root 9272296 Dec 21 11:23 00000013.tar.Zaa -rwxrwxrwx 1 root root 0 Dec 21 11:25 XYZ~2.P -rwxrwxrwx 1 root root 0 Dec 21 14:12 x.y.z.p # Anybody know a solution to this or is it a bug?

5.File Snapshots like Volume shadow copy in Windows 2003
Ok, I'm driving for our internal IT group to get a server and install Red Hat on it for File Serving, but the oppositions key selling point for them and Windows 2003 is the Volume Shadow Copy feature (enables live backup of open files - among the benefits). Is there a similar feature in Red Hat?
