Re: [SLUG] Thumbdrive with a problem.
FAT32 is easily usable by both Windows and Linux. But it suffers from the same shortcomings Peter mentioned. It has no concept at all of file permissions, so copying anything to it is going to result in the destination having permissions set to whatever the default is for that mount point.

[SLUG] Further to the USB Modem installation.
After a chat with Amos, I went searching for any experience with the installation of a ZTE MF626 USB modem (= the white Telstra dongle, $150 from the Telstra shop along with free sniff if you mention Linux). A dogpile yielded the following: ubuntuforums.org/showthread.php?t=1147685 which is headed "How to install modem ZTE MF626 HSDPA in Jaunty". It involves getting the latest modeswitch, installing same and then editing it to recognise a modem. Those who tried it seem satisfied. Anybody in SLUG tried it?

[SLUG] Thumbdrive with a problem.
I've been given a small thumbdrive. I can copy a file to the drive. The drive changes the file's permissions and will not allow them to be altered: Owner Access: read and write allothers: read only. Execute: (tick) Allow executing file as program. Copy the file back out of the drive and the settings remain unchanged, although they can be altered manually. Does anyone know a method whereby the drive leaves the permissions alone?

Hi Rick gethostbyname is part of GNU libc implementation. Therefore, you'd have to check out its resolver library to do anything serious with `options debug` on your /etc/resolv.conf (its disabled by default for some reason). Other implementations such as AIX which you use has it enabled by default. AFAIK, most BSDs have them enabled too.

Re: [SLUG] debugging dns resolution issues with RES_OPTIONS="debug"
Rick, Thanks - yes, that will help, though I don't think I'll get close enough to the problem to decide if it's ip communications or a windows dns server issue. (I could do other connectivity tests to the dns servers, same result) I came across these options when working with a really nasty performance problem, involving AIX dns clients, resolving names on win2k3 servers. At the time, I was being pushed to populate hosts files on dozens of unix hosts, rather than get to the bottom of what was going on. Eventually, we found that the AIX version in use would attempt ipv6 style dns client behaviour several times, before failing back to ipv4 behaviour. At the time, IBM gave us no support what so ever - just blamed microsoft. As usual, the way to solve a vendor war is, get to the root of the problem. I'm pretty clueless on where gethostbyname lives in the os. My guess would be, a shared library that many programs link against, rather than part of the kernel.. This was the kind of info I was looking for. Thanks for everybody's input so far. b Ben Burke wrote: Yes, I know about dig.
