Limit for bash variable ?
Hello, I need to store some long strings in a bash variable, I'd like to know if there's a limit in length (last version of bash/cygwin 1.5). At the moment the string is 3.185 chars long. It's a temporary situation until I figure something better out.

Rsync (daemon) cannot see loopback connections IP address as 127.0.0.1
Hello, I'm trying to use rsync over SSH without the -e ssh option. The idea is to make rsync --daemon bind on the loopback on the Cygwin box and to connect to this box with a tunnel: ssh -L 873:localhost:873 u...@cygwin_box On the Cygwin Box, the file /etc/rsync.conf contains: [d_drive] read only = yes path = /cygdrive/d/ hosts allow = 127.0.0.1 To backup the Cygwin box, this simple command should do the trick: rsync -avz localhost::d_drive /path This is a simple use of a SSH tunnel. Unfortunately, on the cygwin box, rsync sees the loopback connection (from the SSH tunnel) from its own public IP address instead of 127.0.0.1. So the /etc/rsync.conf should be: [d_drive] read only = yes path = /cygdrive/d/ hosts allow = real_IP_address_instead_of_loopback_address It works but I'd like to backup a lot of Cygwin boxes and having to fill the hosts allow line with a non-generic static value is quite disturbing.

Re: Updating cygwin from a remote shell?
Thomas Walker a écrit : Apologies if this is a newbie question... I did a decent amount of looking through mailing lists but couldn't find anything relevant. I'm a Linux/Unix person by hobby and profession and don't really do much Windows but my family (living in another state) is still rather Windows centric. A hard disk failure ago I decided to place a dirt cheap headless Linux box with mirrored raid on their network and setup cygwin on their Windows machines so that I could cobble together an easy backup solution based on cron, ssh, rdist, and fuse. That all works fine and has done so for some time. I'm a little bit of a security nut though (and sometime also want to be able to add new features for myself and for them) and would like to be able to easily update cygwin and/or install new packages onto the Windows/Cygwin boxes from a remote shell. I know I can setup VNC and all that fun stuff and run setup.exe but is there an easier way? The usual yum, apt, up2date, etc. don't seem to be options... I think that dpkg exists but you cannot update binaries that are running. If you are connected with ssh, the setup process will stop if it has to update bash, openssh, cygrunsrv and cygwin...

Re: setup.exe command line parameters
Ralph Hempel a écrit : cuicui wrote: You need to modify the setup.ini file, create virtual (empty) package that belongs to the Base category and make all the additional packages you want dependant of this virtual package by filling the requires field. Ok, so how do you keep the setup.ini from being downloaded every time you connect to the server? Mmm, I'm not sure there's an overlay mechanism, in my case I basically append the virtual package text at the end of the setup.ini everytime I collect a fresh package list. My plan is to have a c:\cygwinSetup directory on my local server, where I have the latest and greatest packages I need, and then on each machine (usually vmware machines) that I need to install on, I have a possibly different set of needs besides Base. So one set of scripts grabs all the packages we need to the server, and the other set of scripts builds the cygwin installation on the local machines. This reduces the overall load on the mirrors. I guess I'm actually implementing a local mirror for the packages, now that I think about it. Is there a way to limit the scope of the packages that I choose to mirror locally? Maintaining a mirror simply consists in keeping the installation files in one place and sticking to a mirror for more convenience (otherwise a new directory named by the mirror URL is created in the repository). The setup scopes the packages by itself as far as it's only downloading the packages you choose to install (+ the base packages).

Re: setup.exe command line parameters
Ralph Hempel a écrit : With all of the talk about setup package selection and install procedures, I have a little story. One of the things I do for fun is write replacement firmware for the LEGO MINDSTORMS NXT - specifically pbLua. I needed an easy way to build the ARM7 cross compiler, and to locate and program the NXT via libusb. More importantly, I needed to share how to build it, which I have not yet done. Long story short, I ended up using a hacked older version of setup.exe that accepted a -p parameter and a list of packages. It worked great! Is there a compelling reason why that patch can't be applied to the current setup and released? Are there security or stability issues I'm not thinking about? That being said, I CAN run setup.exe in unattended quiet mode and get a BASE cygwin install done, and I'm quite happy with that. But I'd really, really like to specify packages on the command line. Can I help by offering to update the patch to the current setup? You need to modify the setup.ini file, create virtual (empty) package that belongs to the Base category and make all the additional packages you want dependant of this virtual package by filling the requires field. That's a known-working workaround i'm using for quite a long time.

It means that you can have the same (network) drive letter assigned multiple times, one in each userland.

reg.exe vs. regtool behaviour

I found a workaround with bc to obtain the hexadecimal value directly: regtool -q get /HKLM/.../ProductVersion | sed -e s/^/obase=16;/ | bc But I'm wondering what's the rule here? Is regtool always returning decimal values for REG_DWORD type? Is it possible to have the hex value with regtool directly?

Hi!

Are you sure this is the best way to achieve whatever end result
you're using? Give us some more detail, maybe there's a better way
without having to know this stuff.
For example, What type of line endings (CRLF, LF, etc.). Where does
Cygwin store this sort of information, if anywhere?
The type of line-endings can be inferred from the mount-mode of the
root directory; it's not stored explicitly anywhere AFAIK. Most of
the remaining information is stored in
/etc/setup/last-{action,cache,connection,mirror}.
BTW, i've recently planned to autoupdate the Cygwin environment (using
switches of setup.exe and a virtual package on Base category) on the
workstations i manage and i noticed that remaining /etc/setup/last-*
files take precedence over the setup switches.
In other words if the last action was Install from Internet and the
setup switch is setup -L ..., the setup will try to download files
from Internet instead of using the local directory only.
That was an issue for me as far as my files are stored on a public SaMBa
share (read only).
Cleaning /etc/setup/last-* before setup files does the trick.
Anyway, this was just to mention a possible minor bug. Another
suggestion for quiet setup: no possibilities for the user to close the
window (equivalent to the /qb! option of msiexec) when using the quiet
option...
All the best,
Nicolas C.
