If somebody needs it, I compiled for myself at the beginning of my android experience nmap, netcat, joe, hts/htc, kismet, aircrack, wireless-tools,gpsd.. as static compiled binaries. For all the non daily use stuff I'm using debian in a chroot environment (bootdeb) much more flexible.

I know nc (netcat) is part of busybox, so that is one less thing to think about.

I checked for cron earlier this week but got the message "crontab: unknown uid 0" when running crontab -e
rsync + cron would be even more amazing

This is because there is no /etc/passwd file...
You can add one that contain the following line:
root::0:0:root:/data:/system/xbin/ash

but then you will face: chdir (/var/spool/cron/crontabs): no such file or directory !

Need to check if we can tweak crontab config in busybox...

thanks for the info!
I'll be sure to keep an eye on this thread

call crond -c to define an alternate crontab directory, for instance:
crond -c /data/data/crontabs

[stevenz]

Made the /etc/passwd file  containing;

root::0:0:root:/data:/system/xbin/ash

Created /etc/root with

* * * * *  echo "New line" >> /data/cronout

Started crond using;

crond -l 0 -L /var/log/cron.log -c /etc (-l and -L switches are just for excessive logging)

crond tries to run scripts via /bin/sh so symlinked /bin to /system/bin to keep it happy.

And bingo, crond happily running amending a line to a file once a minute.

The crontab command needs the -c switch to change the working folder to /etc as well ifyou use that for anything.

Checked: this is actually something we can set in busybox configuration.
Paul, would you mind to build a new busybox with something that make more sense for the crond spool directory ? By the way, could you also enable the bbconfig applet so that we can extract busybox configuration file from the binary ?

What about adding:
mkdir /var
mkdir /var/spool
mkdir /var/spool/cron
mkdir /var/spool/cron/crontabs

to /etc/init.rc so that it creates these folders automatically after it mounts /system, would that do it?

Here's a busybox with bbconfig enabled and with the crond directory set to /data/cron. Feels like a good idea to work together to also get busybox as 'right' as possible for Android.

Incidentally, busybox compilation with the Google toolchain is indeed a PITA, I use codesourcery.

If busybox was recompiled to resolve exactly like ping does, the network functions will work properly. Currently, none of them can resolve an IP from a hostname. Its almost like it needs a /etc/resolv.conf, not all that useful.

Great! Yeah, I think there are still too much applets in your busybox.... the more obvious to me being ftpd, httpd, telnetd, udhcpd, syslogd and maybe some more.
Well, unless we want a real unix system in parallel to android ...

I use my own brewed toolchain.... optimized for armv6j / arm1136jf-s (the cpu inside the MSM7200) and with compilation switch set to optimize for speed

New release for rsync.
Changes are actually related to dropbear, not to rsync itself.
See changelog here.

Resolv.conf won't help. Busybox needs to be linked against android's own libc.

Cool down, I regularly use httpd to access a r/o copy of my personal wiki on my Hero.

That was interesting.  Which Wiki do you use on the Hero?

How does one go about achieving this when running a ship version of the OS?

I'm not sure that's possible. You would have to replace the libc headers and object-files in your toolchain with the ones from android. I wouldn't know where to start, though.

I used http://github.com/tm...m/droid-wrapper together with a conglomerate of the android sources (to get the header's) and parts of the NDK to get some binaries (like crtend_android.o). That is enough to compile not too large projects and link them dynamically. Unfortunately busybox's build-system refused to cooperate. Perhaps it would be easier to work on androids Toolbox…

I might give it another try in late February when I have some days off.

Have a nice day

Im trying to install the rsync binary supplied at the start of this thread using the RA tools.

Im getting the error:

Copying files.........
E: Cant Symlink /system/xbin/ssh
E: Failure at line 14
symlink dropbear SYSTEM:xbin/ssh

Any ideas?

[freeasabeer]

Maybe... was the previous release of rsync already installed on you phone ?
