Dolio: /* WebOS 1.3.1 */ This is old news, I got it working....

Is /opt/bin/crontab -e the original cron file that we should not be editing? If so does the package install of of cron need to be updated?

== ==

Keep these things in mind when running the cron daemon that ships with the Pre.

* The daemon reads files in /etc/cron/crontabs/
* crontab -e edits files in /var/spool/cron/crontabs/
* When crontab -e does an edit, it makes a temporary copy of the file, which is what the user actually edits, verifies the changes, and then replaces the existing file.
* Changes should be made using a regular editor to /etc/cron/crontabs/*

== Alternate event.d config ==

I could only get crond to run on startup with these parameters in mod-crond...

start on stopped finish<br>
stop on runlevel [!2]

But then it has the issues with stopping when going to sleep.

Just a heads up that the cron log file is not rotated, if filled up my /var volume one day and I had to manually purge it. I intend to look into getting the cron log added to the normal log file rotations, unless someone beats me to it... --[[User:Dolio|Dolio]] 05:38, 5 July 2010 (UTC)

Question: Does the 'governor' select in Govnah (IE: Screenstate for example) keep governing the CPU even after 'Govnah' is closed? --irwinr

Dolio: /* Bug: Update to WebOS 1.4.0 */ working again! mostly...

== Bugs: Paste? ==
- Can't seem to figure out how to paste something that was copied from another app/msg/web site. The old paste shortcut of "Gesture + V" doesn't work (because its being used for other things). I tried to "Insert" shortcut, but it didn't do anything.
--[[User:Zinge|Zinge]] 08:58, 7 August 2009 (UTC)

- Tossing in another request to get a solution in for pasting: as it stands there is no way to get some symbols (specifically curly braces) into the terminal - tough to do a rescan :) -- [[User:Flare576|Flare576]] 17:51, 20 August 2009 (UTC)

- I triple the motion. Can we distinguish gesture HOLD from gesture tap? We could then leave gesture HOLD V as paste and use tap and double-tap as activating the special cursor movement etc. currently in place (AWESOME JOB on this app by the way). I also second the motion for needing '{'. This is crippling. Couldn't we just leave access to the normal symbol input by hitting some unused key combo (gesture sym?) then we'd be able to get any symbol we need with a little effort.
[[User:MerlinMM|MerlinMM]]

Running in the emulator on Ubuntu, my desktop zero key gets turned into an at sign. This is the zero along the top just to the right of nine, not the one on the numeric keypad. Is there a way to correct that?

== Ansi bugs ==
Scrolling in BX is fixed. Thanks! terminal is a killer app.

Still have a bug when typing a message in IRC that's long enough to require horizontal scrolling. Instead of scrolling it does weird single-char newlines and status bar is lost.

Also when using arrow keys to move around in vim (with TERM=linux and syntax/color on), what seems to be ansi color code artifacts are printed. Arrows do work, but it's unusable due to artifacts. --[[User:T3rmin|T3rmin]] 18:05, 14 August 2009 (UTC)

There seems to be a problem when scrolling in any direction in nano? After awhile the display is completely ruined with characters all over the screen and no longer tell where you are or what you are editing? Seems to be a repaint issue. Also, nano doesn't seem to use the full width of the screen if I use any of the smaller fonts --[[User:TC|TC]] 19:44, 28 October 2009 (GMT)

== New Version Changelog? ==

The newest version from the feed seems to be 0.1.6. Anybody know what changes have been made? --[[User:Zinge|Zinge]] 19:30, 1 August 2009 (UTC)

== Font Size Feature Request ==
Well done! I notice that there are two fonts, normal and small. Would it be possible to add an intermediate font size? The 40 col is to large for seeing much and the 80 col is far to small. Would it be possible to have a ~60col font? --[[user:Dreadchicken|Dreadchicken]]

: Also, could you add a "large" font size? I don't like the small sizes for little one-line commands (wget, etc). I guess ultimately it'd be nice to have in that combo box a handful of sizes. Thank you so much for the mind-blowing awesomeness of this app, by the way. [[User:Michaelb|Michaelb]] 18:46, 17 August 2009 (UTC)

: Yes, please, an "extremely large" font for those of us whose eyesight is going. Maybe twice the size of the 6x10. --[[User:Lordbah|Lordbah]] 03:51, 2 September 2009 (UTC)

: I agree, larger fonts are an absolute necessity, please add a 10x10 and a 12x12, I can barely read the 8x8 and the 6x10. --[[user:bjrosen|bjrosen]] Oct 8, 2009

== Broadcast messages when phone sleeps/wakes ==

Has anyone figured out how to stop the broadcast messages generated on the Terminal when the phone sleeps and wakes? They clobber whatever's on the screen if you happen to turn off the phone while Terminal is open.

Other than this, great app. I'm eternally grateful. :) --[[User:zorinlynx|zorinlynx]]

These characters have not been implemented yet, but as a work-around, you can use tee or tee -a.

==Colors Sticking, and Permissions==
Would it be possible to set the foreground color permanently, so that I don't havve to set it each time I log in?

I've also noticed that when I open the application, sometimes it automatically logs me in as root. How can I disable this?

Thanks for your awesome work!! -[[User:Hopspitfire|hopspitfire]] 05:47, 16 August 2009 (UTC)

I think one solution for disabling root access is to go into
/var/usr/palm/applications/org.webosinternals.terminal/app/controllers
and edit '''session-assistant.js'''
Search for the line that reads
this.termplugin.start("root");
and change 'root' to your username.
[[User:Clebio|Clebio]] 20:57, 16 August 2009 (UTC)

:That worked perfectly! Thank you.
:I'm still having trouble with the colors sticking, now when I change a color in the preferences menu and go back to the terminal, the entire screen freezes (It responds to <orange><sym><r>, but won't show the boot logo as it's shutting down, and ssh responds normally). Is this a bug? -[[User:Hopspitfire|hopspitfire]] 04:13, 17 August 2009 (UTC)

:This root fix works fine for startup, but I've noticed that if I go into preferences and exit out, I'm back as root. Is there another file we need to edit? Can we work this into the preferences? [[User:Crynyd|Crynyd]] 16:16, 10 November 2009 (UTC)

Terminal displays blank screen after install
----

It will display nothing that I type, I have tried rebooting the phone with no luck. I did see an message that looked like an error during the install:

Configuring org.webosinternals.termplugin
(offline root mode: not running org.webosinternals.termplugin.postinst)

Could the offline root mode error above be causing this? I was not in Dev mode when I installed this, should I have been?

==Curved mask blocks text on screen corners==

There used to be padding on the top and bottom of the screen to keep the curved corners of the mojo view from blocking text. Why were they removed? --[[User:Zorinlynx|Zorinlynx]] 02:12, 20 August 2009 (UTC)

Can we get an easier way of tabbing? Say sym+period?

: The Treo mapped Shift+Space to tab, which I think is way more convenient than Sym+I (why I?). Is that something the Terminal app on the Pre can mimic? --[[User:Jameslin|Jameslin]] 18:37, 7 October 2009 (UTC)

== On Screen Keyboard? ==

Any plans to integrate or implement something similar to the recently released OSK to the Terminal app? I think it would be very handy for landscape mode. --[[User:Roto|Roto]] 01:27, 29 August 2009 (UTC)

== Limited User? ==

Once there is a limited user account created, it would be nice if the Terminal could be set to use that account instead of root by default, as well as start in the directory /var/home/$USER

I second this, you should never run as root, this is Linux not Windoze. --[[user:bjrosen|bjrosen]] Oct 8, 2009

It would be awesome of the following characters could be implemented:
`
^
{

[

--[[User:JackieRipper|JackieRipper]]

Could you provide a programable map for the special keys. You have a two key sequence for ESC which is incredible painful for Emacs users who use CTRL and ESC constantly. I would like to be able to map ESC to the up arrow key and leave CTRL on the Sym key. --[[user:bjrosen|bjrosen]] Oct 8, 2009

== Bug: Phone lock up due to Preferences ==

I installed webdoc and then the terminal application today (11/08/2009). After running terminal, I selected the Preferences. I changed the setting for the size of the terminal to 4X6 (I think). After that, I was stuck. I couldn't figure out how to get back to the terminal. I tried swiping back, pushing the preferences to the top (and out). It would not unload. If I clicked on the screen, the preferences would re-appear. I was unable to run any other applications or type on the keypad. I couldn't power off the device by holding the power key down. Plugging the pre into my laptop didn't generate the usual menu of usb drive, charge. Eventually, my only option was to pop the battery out and restart. My pre restarted normally, no harm down.

==Terminal Questions==

Is it possible to setup aliases in the terminal app similar to editing .bash_aliases? --[[User:Elpollodiablo1|Elpollodiablo1]] 01:54, 30 December 2009 (UTC)
I figured this out, you need to create a file called .profile and put it in users directory. inside the file add aliases (ex alias la = 'ls -la')--[[User:Elpollodiablo1|Elpollodiablo1]] 03:30, 30 December 2009 (UTC)

== More bugs ==
8x8 font continues off the bottom of the phone (but eventually does begin to scroll).

Opening up special characters pull-down wipes previous terminal session, requiring you to open a new copy of terminal if you want to look up a special character without losing the line you were typing.

== Bug: Update to WebOS 1.4.0 ==
Just installed the update to WebOS 1.4.0 - Terminal begins to start, then crashes and the phone resets. Worked fine before the update. Is this a problem for anyone else? -- [[User:EagleG33k|EagleG33k]] 03:00, 1 March 2010 (UTC)

:Yes the 1.4 Update broke Terminal. I really hope someone fixes it. I tried Terminus and it is lacking many important features that Terminal did well. --[[User:Daemon|Daemon]] 05:48, 1 March 2010 (UTC)

:Yes, I'm having the same trouble and an identical problem with [[Application talk:Luna Manager]], and [[Application talk:JsTop]] isn't quite working right.

:: Good news, the terminal service app had an update yesterday, or earlier, and the terminal app now works again. With a few minor problems that I can live with.

Crond

2009-12-25T09:39:48Z

Dolio: Add datestamps to the lines for the crondtest

== Enabling Stock Cron==

The [[Patch webOS GPS Tracking]] guide had a nice bit about enabling crond on the Pre. It looks like its already pre-installed, just not set up to start. You will need to edit /etc/event.d/mod-crond (don't modify the existing crond startup-script) to enable cron to start. The settings should look like this:

<pre><nowiki>
# -*- mode: conf; -*-

# jobfile for busybox crond, with pre-start commands to create the
# directory and files it wants by default. That there's not 'start
# on' stanza is intentional: it's for development use only. We can
# turn it on later if we need it, e.g. to keep the clock synced. It
# does work.

start on stopped configure
stop on started start_update

# If the above do not work with WebOS above 1.3, try these - xorg
# start on stopped finish
# stop on runlevel [!2]

respawn

exec /usr/sbin/crond -f -L /var/log/crond

pre-start script
mkdir -p /var/spool/cron/crontabs
ln -sf /etc/cron/crontabs/root /var/spool/cron/crontabs/root
end script
</nowiki></pre>

A few notes here. Unlike the Dropbear and other scripts I make my upstart scripts so that essential services don't stop when the device exists runlevel 2. This seems to shutdown these services whenever the device locks. I prefer that my upstart services stop only when the updater runs. Also I have made cron log to a separate file under /var/log so that it can be monitored better.

One thing to note about the standard script for cron on the Pre is that the /var/spool/cron/crontabs directory is created every time the process runs and a symlink to /etc/cron/crontabs/root is created. To my surprise this file does not exist. So we need to create it:

<pre><nowiki>
sudo mkdir -p /etc/cron/crontabs
sudo sh -c 'echo > /etc/cron/crontabs/root'
</nowiki></pre>

Now to start up crond:

<pre><nowiki>sudo -i initctl start crond</nowiki></pre>

*Note for clarification: I attempted this and it all works OK, but I can't figure out how to actually schedule jobs. I modified /etc/cron/crontabs/root, but nothing seems to happen. I also tried crontab -e, and that doesn't seem to do anything either. I suggest adding a note here clarifying what needs to be done to actually add a cron job. -irwinr

*Clarification: Edit /etc/cron/crontabs/root with test content something like this:

<pre><nowiki>
# format:
# minute(0-59) hour(0-23) day(1-31) month(1-12) weekday(0-6) command
* * * * * echo "CronTest -" `date` >> /var/crondtest
</nowiki></pre>

Then restart crond like this:

<pre><nowiki>
sudo -i initctl stop crond
sudo -i initctl start crond
</nowiki></pre>

This test will result in a test file at /var/crondtest that grows at the rate of one line per minute. You can count the lines and output the end of the file with the following commands. Also try a reboot to make sure everything is starting up properly. If everything is working make sure to remove or comment out the CronTest task and restart crond.

<pre><nowiki>
grep -c "" /var/crondtest
tail /var/crondtest
</nowiki></pre>

==Alternative (ipkg-opt) Method==

* Another request for clarification: It's not clear which of these two methods are preferred. This method appears to not work when the screen is off (rendering cron pretty useless), the above method appears to delete the cron entries every time the cron daemon starts. Has anyone worked out either of these issues? -irwinr.

crond is a system that allows command to be run at specified intervals.

Do not use the built in crontab -e as it is overwritten on each boot.

Optware has cron available as an installable package, and using /opt/etc/cron.d/ for cron files will not conflict with any Palm files.

<pre><nowiki>
sudo -i
mount -o remount,rw /
ipkg-opt update
ipkg-opt install cron
/opt/bin/crontab -e
# Add script and intervals here
mount -o remount,ro /
</nowiki></pre>

This does not seem to work when the phone's screen turns off. I tried it plugged in for two minutes then unplugged, and turned the screen off for two minutes. I ran
<pre><nowiki>echo `date` >> sleep.log</nowiki></pre>

And got...

<pre><nowiki>
# cat sleep.log
Wed Jul 1 18:27:01 CDT 2009
Wed Jul 1 18:28:01 CDT 2009
Wed Jul 1 18:30:16 CDT 2009 ## Turned the screen back on. It seems to play catch up.
Wed Jul 1 18:30:16 CDT 2009

== Uninstallation before update requirements? ==

I do not see how to uninstall. It appears to me that the Optware instalation should be safe to leave installed as implied by the "we use /opt so as not to be overwritten by an update" statement. Are the Quilt installation steps mentioned here also safe to leave applied during a WebOS update? It does sound like patches and tweaks installed by quilt should be removed prior to an update. If the command `cd / ; quilt applied` found at [[Applying_Patches#Listing_Applied_Patches]] reports that no patches are applied is it safe for an update?

So, If I am correct in my assumptions above then everything found in /opt is safe to leave in place during an update. But perhaps things outside that folder are not? For example I've configured dyndns per [http://palmpre-hacks.com/palm-pre-hacks/how-to-ssh-into-your-palm-pre/] which required a new boot script named ''/etc/ppp/ip-up.d/09update-ddns'', would this cause problems. Similarly per [http://palmpre-hacks.com/palm-pre-hacks/how-to-set-up-google-gps-tracking-on-your-palm-pre/] installing a lighttp service requires the addition of a ''/etc/event.d/optware-lighttpd'' script, would this also cause WebOS update problems?

Thank you for any insights you might have, delaying my 1.2 update till I feel more confident... --[[User:Dolio|Dolio]] 06:49, 1 October 2009 (UTC)

: So I did the 1.2.0 update and it appears that everything I described above was fine including the ddns and lighttpd additions which I left in place during the update. I also performed the 1.2.1 update which initially appeared to be fine, but since then I have been prompted to install the 1.2.1 update multiple times. At this point I have installed the 1.2.1 update at least 3 times and have finally chosen to ignore it by [[Blocking_Updates]] until I figure out what's going on. Oddly enough I believe that after the 1.2.0 update I was still able to ssh into my Pre ''(I could be mistaken)'', but I am sure that the 1.2.1 update is overwriting the password file as I have to use the usb console to add my user after each update. Anyway, that's all neither here not there and I just thought I would let anyone reading this know how things turned out after being spooked by the great [http://forums.precentral.net/palm-pre/205670-palm-profile-login-problems-4.html#post1930274 palm-profile-login-problems] during the initial 1.2.0 update push. --[[User:Dolio|Dolio]] 22:29, 20 October 2009 (UTC)

: I have not tried this but I suspect you could move the folder to another location and then create a symlink from it's original location. For example this will make a symlink in your home folder named internal.media '''ln -s /media/internal/ ~/internal.media'''. It could be dangerous to move things like bin folders because once moved you might find that you can no longer run those commands (Shrugs)... --[[User:Dolio|Dolio]] 11:22, 7 November 2009 (UTC)

Talk:Backing Up via Rsync

2009-10-01T07:03:21Z

Dolio: sp

==Rsync Daemon==

Why turn on the rsync daemon at all? This could easily be accomplished simply by running

'''rsync -HrlptgoDPvvS --force --delete --del --stats -e ssh root@IPADDRESS:/ /media/pre-backup/'''

Also, since ''-P'' includes ''--progress'', there's no reason to call it a second time.

-JackieRipper

We don't have a root password set up on the Pre, it's using sudo therefore that's why ssh won't work. Rsyncd.conf gives the rsync daemon root privileges so it can mirror the device. I'm be open to suggestions, but I'm trying to make this fit in with the [[Next_steps | next steps]] guide and limit the number of steps.

Thanks for pointing out the redundancy on --progress.

-hopspitfire

Ahhh yes. I keep forgetting that not everyone set up keys for root access.

-JackieRipper

I've added these to my .profile on the Pre:
exclude1="--exclude=/proc --exclude=/sys --exclude=/tmp/webdiskcache"
exclude2="--exclude=/media/internal/AUDIO --exclude=/media/internal/Place_iTunes_Uses"
syncopt1="-az --partial --progress --stats --delete-after --bwlimit=300 --numeric-ids"
syncpath=" / me@$IPADDRESS:~/PreRSync/ "
alias Sync='d=`date +%Y%m%d.%H%M%S` ; sudo rsync --rsync-path=sudo\ rsync $syncopt1 -b --backup-dir=~/PreRSync.bak/$d $syncpath $exclude1 $exclude2'
On the server in the /etc/sudoers I've added something like this (not sure this is the most secure thing to do):
me ALL=(ALL) ALL, NOPASSWD: /usr/bin/rsync
Now I can simply login to the Pre and run Sync, it prompts for a password at the server but hostkeys could be used to avoid that.
The addition of the dated backup options means that I get a copy of any removed or overwritten files at the server.
I use something called cwrsync which I believe is the cygwin rsync command without installing all of cygwin, might be handy and simple enough for windows users.

==Pre Rebooting Issue==

If you don't exclude some of the directories then the Pre reboots when the backup process touches them. [[User:hmagoo|-hmagoo]]

:Can you specify which files/directories prompt the reboot? -[[User:Hopspitfire|hopspitfire]] 02:57, 20 August 2009 (UTC)

::I could narrow it down to proc and/or sys, that's narrow enough for me to exclude both, any progress on restore testing? I'm not running an emulator. [[User:hmagoo|-hmagoo]]

:I tested the restore process and it works. Can you run the backup process and send the output to a file (rsync ... > /media/internal/rsync.log) and post it? -[[User:Hopspitfire|hopspitfire]] 00:49, 24 August 2009 (UTC)

::[http://sites.google.com/site/hmagoosite/rsync-outputs.tar.gz rsync-outputs.tar.gz] this was the console and log output from running a backup. I had already a backup in place in the destination but excluded /dev, /sys/ and /proc initially, ran it this time without those exclusions to test it out (again, as I saw this reboot the very first time I tried this method). rebooted right after this line in the console, similar in the log.
rsync: read errors mapping "/sys/devices/platform/lcd-controller/ctrl_reg_dump" (in root): No data available (61)

::I ran the backup again excluding /sys and everything completed, only errors I got in the console were:

[[User:hmagoo|-hmagoo]]

Thanks for attaching your log. /sys and /proc don't need to be included in the backup, but /dev does (to initialize devices on boot). After testing the backup and restore, the easiest way is just mkdir the /sys and /proc directories and exlude them in the backup. Does the pre still restart when you excluded those directories?? -[[User:Hopspitfire|hopspitfire]] 21:23, 26 August 2009 (UTC)

Shouldn't /dev exist fine after a restore and before rsync backup restore? I guess if you made some strange volume changes, but still. --[[User:NetWhiz|NetWhiz]] 21:59, 26 August 2009 (UTC)

I was using /dev as an example of a directory that _shouldn't_ be excluded in the backup process, so /dev will exist after a backup prior to a restore (otherwise the Pre won't boot because it can't initialize the mapper devices for storage). -[[User:Hopspitfire|hopspitfire]] 22:37, 26 August 2009 (UTC)

You mean it SHOULD be excluded b/c you will not need to restore it. --[[User:NetWhiz|NetWhiz]] 22:54, 26 August 2009 (UTC)

(failed=reboot).. failed with no excludes. successful with /dev/,/proc,/sys excluded. successful with /sys excluded. but with those three error messages.--[[User:Hmagoo|Hmagoo]] 23:52, 26 August 2009 (UTC)

:@NetWhiz: /dev needs to be populated on the actual filesystem (before devfs/udev get loaded) for a *nix system to boot.

:@Hmagoo: Thanks, I went ahead and fixed the lines in the article.

I understand, BUT when you do a restore with WebOS Doctor it will already be there. Are we not talking about the same thing or are we just cross talking? --[[User:NetWhiz|NetWhiz]] 01:11, 27 August 2009 (UTC)

:OH, I'm talking about a restore using rsync ;) (in this guide, after the intial webOS Doctor). I still don't know if we should be overwriting the entire system (with the rsync backup, including /dev). Any ideas on this? My reasoning for doing a full system overwrite is version compatibility. -[[User:Hopspitfire|hopspitfire]] 01:16, 27 August 2009 (UTC)

:LOL! I would say NOT to overwrite /dev b/c it should already be setup correctly and there is nothing anyone should be doing in there with any mod anyway that I have seen. Trying to overwrite some of the virtual devices can be a BAD thing as some have seen (crashes, freezes, etc.) Just my thoughts. --[[User:NetWhiz|NetWhiz]] 01:58, 27 August 2009 (UTC)
