A script to aid in troubleshooting Tinycore installations.
« on: June 07, 2020, 07:28:41 AM »
The attached script is intended to gather some baseline information about a Tinycore Linux installation. The design goals of the script
were as follows:
1. No dependencies. Use only commands that are part of the base system.
2. Keep the results file generated small so that it can be an attachment in a users post.
3. Format the results file to make it easier to review.
4. Try to stay focused on generic and Tinycore specific data.
5. Optimize for speed where possible.

On my old 800 Mhz, 512 Meg RAM, PATA drives, TC4 system it takes about 50 seconds to complete.
On my Dell E310 2.4Ghz, 3 Gig RAM, SATA drives, TC10 system it takes about 11 seconds to complete.
About 80% of the time is spent on MD5 checks.

The results are saved in a file called  TCscanYYMMDDHHMMSS.txt  where  YYMMDDHHMMSS  is a date code.

The format of the file is as follows:

It starts with a time stamp and a Table of Contents listing which sections were created and what they contain
Code: [Select]
Sun Jun  7 09:58:50 UTC 2020

Table of Contents

Sect 1    TC version, uname, tcedir, mydata.tgz status, /etc/sysconfig/
Sect 2    tcemirror, repo URL, repo URL reachable, showbootcodes, Some CPU flags
Sect 3    free, /proc/swaps, mounts, disk free
Sect 4    ifconfig, route -n, /etc/resolv.conf
Sect 5    lsmod
Sect 6    .xsession, .profile
Sect 7    bootsync.sh, bootlocal.sh, .filetool.lst, .xfiletool.lst
Sect 8    onboot.lst, ondemand
Sect 9    Missing md5 files, Failed md5 checks, Local/Repo md5 files differ
Sect 10   Orphaned md5 and dep files
Sect 11   find bootloader config file
Sect 12   Some dmesg lines
Sect 13   Some Xorg.0.log lines
Sect 14   /proc/bus/input/devices

Then each section is listed with the contents in a sort of question/answer format. Text that starts in the first column is the question.
Text that is indented is the answer. The intent behind this is to make it easier to visually scan the file contents. Here's what a section
looks like
Code: [Select]
#----------------------------------------------------------------------------------
Sect 1    TC version, uname, tcedir, mydata.tgz status, /etc/sysconfig/

TC version=
10.1

uname=
Linux E310 4.19.10-tinycore #1999 SMP Tue Dec 18 13:36:47 UTC 2018 i686 GNU/Linux

tcedir=
/mnt/sda1/tce

mydata.tgz status=
-rw-rw-r-- 1 tc staff 574K May 16 23:50 /mnt/sda1/tce/mydata.tgz

/etc/sysconfig/=
Xserver         Xorg
backup          1
backup_device   sda1/tce
cdroms          /dev/sr1 /dev/sr0
desktop         flwm_topside
icons           wbar
keymap          KEYMAP=us
language        LANG=C
mydata          mydata
newmodules     
ntpserver       pool.ntp.org
tcuser          tc

The attached  TCscan200607095849.txt  file is what a complete scan looks like.

To try the script just download it and:
Code: [Select]
chmod 775 TCscan.sh
./TCscan.sh
The script echoes its progress to the screen as it runs.

    [EDIT]: Updated attached script to version 0.2, Jun 16, 2020.  Rich
    [EDIT]: Updated attached script to version 0.3, Jun 17, 2020.  Rich

Hi, Rich!

Thank You, very interesting and covenient tool, good for learning.
Of course I started it immediately. One remark, it didn't succeed finding my grub2 bootloader.
Code: [Select]
#-------------------------------------------------------------------------------
Sect 11   find bootloader config file                                           
                                                                               
                                                                               
        No bootloader config files found.

Hi jazzbiker
... it didn't succeed finding my grub2 bootloader. ...
That's quite possible. The script only looks at what is visible. If the partition  grub  is installed on is not mounted, it is not visible
and will not be found. I have a couple of machines that have  grub  installed on partition number 1 but boot to Tinycore on a
different partition. The script will not find  grub  on those machines because the partition doesn't get mounted.

I also limit the search to a maximum of 6 subdirectories deep.

Hi Rich,

I always enjoy learning from your scripts.  As I am studying TCscan I saw a couple things to share back:

Sect 8   my onboot.lst file was not found because it is uniquely named, I don't know if this is a common occurrence
  lst=onboot_xorg_jwm_DEBUG64.lst

Sect 10   "Orphaned md5 files" label is showing for the .dep files

That's all, otherwise a few ideas for future:
a listing of the system aliases could be useful

a listing of the env or set command

my bootable USB flash drive bootloaders are
  legacy BIOS using syslinux.cfg
  UEFI BIOS using rEFId

thanks again for all your great support!
Billy

Thank you. It's nice to hear they have some educational value. Hopefully the comments include in the script were helpful too.

The script was primarily aimed at installation issues of newbies. As a result, I tried to focus on default install values. I suppose I
could check for the presence of  lst=  in  /proc/cmdline  to see if an alternate name was specified.

Seems I forgot to edit a line after copying and pasting. Thanks for bringing it to my attention.

Hi Rudock1
I've uploaded an updated version of the script. I added a test for for the  lst=  boot code and corrected the  "Orphaned md5 files"
message to  "Orphaned dep files"  for the  .dep  file test.

If you'd like to confirm I got it right it would be appreciated.

I realize your question is directed to Rudock1 but leaping ahead suggest minor changes

Table of Contents
Sect 8    onboot.lst, ondemand
suggest change to
Sect 8    boot lists including onboot.lst and ondemand

my section 8 output if interested is
Quote
Sect 8    onboot.lst, ondemand

/mnt/sda3/tce/openbox.lst=
   haveged.tcz
   firmware-amdgpu.tcz
   xf86-video-amdgpu.tcz
   Xorg-7.7.tcz
   openbox-config.tcz
   dbus.tcz
   leafpad.tcz
   sakura.tcz
   mc.tcz
   nano.tcz
   mononoki-ttf-fonts.tcz
   fox-dep.tcz

ondemand=
   total 0


I know how to use boot lists....because you taught me  ;D
but without that modest change to heading ....maybe it confuses?

Your script discovers a number of private TCEs and I have no other suggestions

Someone not familiar with those files still won't know what that means.

The  Table of Contents  is sparse by design. It lists only the commands or files included in each section so the data of interest can
quickly be found. The results are intended for someone familiar with Linux commands and Tinycore specific configuration files.
An individual may only be interested in a handful of results, not all of them. A quick glance at the  Table of Contents  should tell
you if I tested for those results.

That's to be expected. Any extension missing an MD5 file will be flagged. So will any extension not listed in the repo or any
extension whose MD5 does not match the repos MD5. These tests merely report discrepancies. It is then up to the person
reviewing the results to determine whether any of those discrepancies indicate a problem.

Hi Rich,
I am happy to say that your Section 8 changes to find customized onboot lst files works perfectly on my system, too.

I use syslinux as one of my bootloaders.  I added these lines below to your script and the .cfg file now shows up in Section 11.
added syslinux to the current list:
Code: [Select]
BootLoaders="*/extlinux */isolinux */grub */syslinux"added syslinux under case "$loader" in
Code: [Select]
        syslinux)
        if [ -f "$config/syslinux.cfg" ]
        then
            echo "$config/syslinux.cfg=" >> $Dest.tmp
            SaveIndentedResults "$config/syslinux.cfg"
            NotFound=0
        else
            echo -e "$config/= ???\n\tNo config file found." >> $Dest.tmp
        fi
        ;;
Thanks again for all you do for Tiny Core.

thx
Billy

Tried script.  Very useful collection of info.  One issue.  Section 9 showed "43 md5 file differences".  When i used the APPS application, ....Maintenance...MD5 checking...it showed up as OK.  Am I missing something?

Further...tried script on another installation.  No issues with MD5 differences.  The first try was on a tc 10.1 system...the second try was on a tc 11.1 system.  Could the first comparision issue be because the script was comparing my local MD5's from a 10.1 systen with the 11.0 repo?

Hi gwalther
... One issue.  Section 9 showed "43 md5 file differences".  When i used the APPS application, ....Maintenance...MD5 checking...it showed up as OK.  Am I missing something?
The first thing the MD5 test does is compute the MD5s of all of your extensions and saves that data in a file. It then processes each
entry in that file. If there isn't a  .md5.txt  file that matches the entries tce name, We flag a missing MD5 file:
Code: [Select]
Missing md5 files= 1
        flash11.tcz.md5.txt

If there is a  .md5.txt  file we compare that MD5 against the value we saved. If they don't agree, you'll see something like this:
Code: [Select]
Failed md5 checks= 1
        libmnl.tcz.md5.txt

Finally, we compare our computed MD5 against the current MD5 in the repository. Any entries not found in the repo get listed first.
Then any entries not matching the repo get listed. That part looks something like this:
Code: [Select]
Local/Repo md5 file differences= 2
        foxit_reader.tcz Not in repo

        FreeRDP.tcz Mismatch
                        Local 61026ec2671addad0d8818d90b72abc0
                        Repo  b6f5bc43d01943b07283ebe5ac5fbfd4
        boost-1.50-dev.tcz Mismatch
                        Local 96de970aab063d92baccce5aea3f434f
                        Repo  6b6520c4ee140755e8fc6ea43e98fae1
A  Not in repo  result may be due to a custom extension.
A  Mismatch  result is likely due to newer versions (updates) of the extension being available in the repository.

That depends. If the installs were on different machines, then no.

If they were on the same machine and you are using the same  tce  directory for both installs, then yes. Of course you should
never be doing something like that.
