Guest Olatho Posted January 14, 2010 Report Share Posted January 14, 2010 Now, if there only were a nice terminal-widget (not application, but a 4x4 widget I could stick on one of mye homescreens), this would be really great. But thanks a lot for your work, all of you! Link to comment Share on other sites More sharing options...
Guest kendon Posted January 14, 2010 Report Share Posted January 14, 2010 (edited) I realise this is probably a stupid question, but do you guys have any examples of what you're wanting to achieve by running this level of shell functionality on the Hero? As much as I'd like to have a fully functional remote Linux shell to ssh into from my Windows PC at work, I'm not sure it'd be of a great deal of use. well, you could use rsync to syncronize directories when toying around with the bootscreen for example, also tree. actually it is all just a matter of how easy it can be to do something. with these tools many things become a one-click thing, you can't do anything you couldn't do before, but you can do it more easily. edit: and yes, actually just because we can.

Guest paulsmith Posted January 14, 2010 Report Share Posted January 14, 2010 thanks for rsync - much appreciated. Im assuming as its in update.zip format - we install by using the RA tools (rebooting , holding home key - like you would another ROM or radio)?

Guest Vano13 Posted January 14, 2010 Report Share Posted January 14, 2010 (edited) Paul, it would be nice if you include mc in the MCR. Android's shell is almost unusable comparing to complete linux shell (bash, csh, etc). mc can help doing many things much faster:) Edited January 14, 2010 by Vano13 Link to comment Share on other sites More sharing options...
Guest Paul Posted January 14, 2010 Report Share Posted January 14, 2010 I wonder how I can get rsync running as a CRON job? P Link to comment Share on other sites More sharing options...
Guest paulsmith Posted January 14, 2010 Report Share Posted January 14, 2010 Cron job running on the phone would be ace for rsync - especially if it will turn on the wi-fi and turn off when finished. My old iPhone had rsync but no cron, I used to have a cron job running on my main media box that would try and rsync every 10mins. Not great but it was great for backing up my phone camera photos and adding audio/video to the phone. Saved my bacon when I dropped it in a cup of tea - phone was kaput but all my photos were safe. I've tried to play around with the android app locale - but I think it COULD be the cause of slow downs on my phone. Giving up on it Link to comment Share on other sites More sharing options...
Guest Paul Posted January 14, 2010 Report Share Posted January 14, 2010 I use Y5 to turn on wifi when i'm at home and off when I go out. I use locale too tho. P Link to comment Share on other sites More sharing options...
Guest freeasabeer Posted January 14, 2010 Report Share Posted January 14, 2010 cron and crond are already in busybox, so isn't it just a matter of tweaking the init.sh to get crond started ? Link to comment Share on other sites More sharing options...
Guest Marcony0 Posted January 14, 2010 Report Share Posted January 14, 2010 this soo feels like many of the familiar Linux forums :) sometime's i feel i should have continued my computer science degree rather doing medical science :\ oh well.. cron job would be interesting :) Link to comment Share on other sites More sharing options...
Guest kieranc Posted January 14, 2010 Report Share Posted January 14, 2010 vi? Pah! Nano ftw! :) P n00b :) nano sux! nice idea though, screen is very useful, i can see rsync being handy too! Link to comment Share on other sites More sharing options...
Guest Paul Posted January 14, 2010 Report Share Posted January 14, 2010 Interesting, should have checked busybox, didn't realise crond is in there! P Link to comment Share on other sites More sharing options...
Guest stevenz Posted January 14, 2010 Report Share Posted January 14, 2010 By default BB crontab seems to look in /var/spool/cron/ and doesn't like working with a uid of 0. The folder can be specified with the -c switch, but if I point this at /etc/ and put the crontab in there the log says "ignoring crontab", along with all the other files in /etc/ - so it either doesn't like the filename or something within it. I've just got; * * * * * echo "New line" >> /data/cronout in the crontab at the moment, guessing it's looking for a user-level file and not finding it due to no uid's?

Guest redcow Posted January 14, 2010 Report Share Posted January 14, 2010 (edited) 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. Edited January 14, 2010 by redcow Link to comment Share on other sites More sharing options...

Guest Andcr Posted January 14, 2010 Report Share Posted January 14, 2010 YAY! rsync on my Hero!! thanks a lot for this, I have been googling for this the last few weeks but nothing turned up. This is amazing, gonna have a play with it :) 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 :) Link to comment Share on other sites More sharing options...

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 !

Guest stevenz Posted January 14, 2010 Report Share Posted January 14, 2010 (edited) 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.

Need to check if we can tweak crontab config in busybox... 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 ? Link to comment Share on other sites More sharing options...

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?

Guest Paul Posted January 14, 2010 Report Share Posted January 14, 2010 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.

P 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. Link to comment Share on other sites More sharing options...

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 ... Incidentally, busybox compilation with the Google toolchain is indeed a PITA, I use codesourcery. I use my own brewed toolchain.... optimized for armv6j / arm1136jf-s (the cpu inside the MSM7200) and with compilation switch set to optimize for speedĀ :) Link to comment Share on other sites More sharing options...
