Talk:The LinkStation firmware flasher
Testing freelink images on LS2, i found out a lot of details on the flashing process. I don't know if this applies to LS1, HG, Kuro, TS as well, so I decided to put my knowledge in this discussion area. Please correct me if I'm wrong, make additions and integrate this stuff in the main article if it's of general use for other platforms.
We have two ways of flashing: EM mode and normal mode. This is true only for normal mode on my LS2:
Flashing the image.dat to hda1 from Windows needs at least the follwing requirements:
1. idtinfo loaded to create /proc/linkstation
root@FL060727:~# lsmod Module Size Used by Tainted: P idtinfo 12428 0 (unused)
if idtinfo is not loaded, do (ignore warnings, this a license problem):
root@FL060727:~# insmod idtinfo Using /lib/modules/2.4.20_mipsel_linkstation/idtinfo.o Warning: loading /lib/modules/2.4.20_mipsel_linkstation/idtinfo.o will taint the kernel: no license See http://www.tux.org/lkml/#export-tainted for information about tainted modules Module idtinfo loaded, with warnings
2. apservd must be executeable. If he is not, do a changemod and start it:
root@FL060727:~# chmod +x /etc/init.d/apservd root@FL060727:~# ls -la /etc/init.d/apservd -rwxr-xr-x 1 root root 1286 Jul 29 23:20 /etc/init.d/apservd root@FL060727:~# /etc/init.d/apservd start Start services: ls_servd on eth0
ls_servd is triggerd by starting apservd. ls_servd is opening a port on your LS2:
root@FL060727:~# netstat -a Active Internet connections (servers and established) ... udp 0 0 *:22936 *:* ...
If you can't see this open port, the flasher won't be able to find your box. All 3 Windows applications which came with your Linkstatation (HD-HLAN FWUpdate.exe, IPSetup.exe and LsBackup.exe) are using this open UDP port to communicate with your Linkstation.
3. Some scripts must be in the right place on your box. As I did not sort out those scripts, which are really essential to the flashing process, I was copying all scripts to hda1:
root@FL060727:~# ls -la /www/script/* -r-xr-xr-x 1 root root 4 Dec 21 2004 /www/script/Yes -rwxr-xr-x 1 root root 32 Dec 21 2004 /www/script/dobackup.sh -r-xr-xr-x 1 root root 206 Dec 21 2004 /www/script/index.htm -rwxr-xr-x 1 root root 528 Dec 21 2004 /www/script/melsub_check_ip.sh -rwxr-xr-x 1 root root 759 Dec 21 2004 /www/script/melsub_disk_rebuild.sh -rwxr-xr-x 1 root root 1764 Dec 21 2004 /www/script/melsub_disk_repair.sh -rwxr-xr-x 1 root root 2056 Dec 21 2004 /www/script/melsub_filepath.sh -rwxr-xr-x 1 root root 2285 Dec 21 2004 /www/script/melsub_flash.sh -rwxr-xr-x 1 root root 876 Dec 21 2004 /www/script/melsub_init.sh -rwxr-xr-x 1 root root 7801 Dec 21 2004 /www/script/melsub_mkprintfilter.sh -rwxr-xr-x 1 root root 828 Dec 21 2004 /www/script/melsub_shutdown.sh -rwxr-xr-x 1 root root 572 Dec 21 2004 /www/script/melsub_shutdown2.sh -rwxr-xr-x 1 root root 99 Dec 21 2004 /www/script/melsub_tmpclean.sh -rwxr-xr-x 1 root root 2824 Dec 21 2004 /www/script/ref_lpr_filter_info.sh -rwxr-xr-x 1 root root 932 Dec 21 2004 /www/script/set_delshare_base.sh -rwxr-xr-x 1 root root 766 Dec 21 2004 /www/script/set_hdd_check_detail.sh -rwxr-xr-x 1 root root 763 Dec 21 2004 /www/script/set_hdd_check_normal.sh -rwxr-xr-x 1 root root 1880 Dec 21 2004 /www/script/set_hdd_format.sh -rwxr-xr-x 1 root root 705 Dec 21 2004 /www/script/set_hdd_format_usb.sh -rwxr-xr-x 1 root root 2542 Dec 21 2004 /www/script/set_ip.sh -rwxr-xr-x 1 root root 46 Dec 21 2004 /www/script/set_printer_queue.sh
At least melsub_flash.sh, melsub_shutdown2.sh and melsub_filepath.sh are needed by the flasher
If these requirements are met, I was able to use the flasher and put new images to my box. There's still much to be done, as at the moment the flashing procedure always ends up with an error message: "Attempt to renew firmware has failed". Nevertheless my box was always working. --Hanfbauer 15:39, 30 July 2006 (EDT) ----
Analysis of HD-HLAN FWUpdate.exe
Leaving my ssh connection open while attempting to flash the box, i could see some errormessages during the flashing process:
root@FL060727:~# sh: line 1: /www/script/melsub_flash.sh: No such file or directory /www/script/melsub_shutdown2.sh: /www/script/melsub_shutdown2.sh: No such file or directory
This was the reason to put the required scripts in right place.
root@FL060729:/mnt# cat: /etc/linkstation_release: No such file or directory
I checked the content of /etc/linkstation_release inside openlink 0.52b and found:
PRODUCTNAME=HD-HLAN(IENOBU) VERSION=2.05 SUBVERSION=HDD 1.2 PRODUCTID=0x00000006 BUILDDATE=2005/04/01 13:35:54
So i put this file inside /etc and flashed again, but ended up with "Attempt to renew firmware has failed". So I have to analyse melsub_flash.sh to find out more. ---- This is true only for EM Mode flashing on my LS2:
Wondering about settings restore
By flashing a firmware after connecting an empty disk to the Linkstation I expected to loose all settings which I had before on my old disk. But this not true. I experienced that some settings must be restored from the flash. Flashing openlink 0.52b to an empty disk and opening buffalos webinterface, I could check for some settings restored from flash:
- Character code
- Shared folder information
- LinkStation name
- Linkstation description
- IP adress
- Default gateway settings
- Workgroup setting
are restored from flash, while
- actual time was reset to 2002 01 01
I relized that the restored settings where not those from my last openlink installation, but those which I did some weeks before, having the original 160 GB HD inside. Opening putty I could check for some files in root directory:
did not change. I discovered that there's a second directory with config files: /etc/melco
bash-2.05a# ls -la total 44 drw-rw-r-- 2 root root 4096 Jan 1 18:02 . drwxr-xr-x 23 root root 4096 Jan 1 18:02 .. -rw-r--r-- 1 root root 0 Dec 20 2004 backup_error_status -rw-r--r-- 1 root root 59 Jul 10 2006 ftpstatus -rw-r--r-- 1 root root 24 Dec 20 2004 groupinfo -rw--w---- 1 root root 105 Jul 15 2006 info -rw-r--r-- 1 root root 35 Aug 26 2005 ntp -rw-r--r-- 1 root root 0 Dec 20 2004 ntp_result -rw-r--r-- 1 root root 57 Aug 25 2005 pcast_mp2000 -rw-r--r-- 1 root root 0 Dec 20 2004 pdcuserinfo -rw-r--r-- 1 root root 11 Aug 29 2005 printer -rw-r--r-- 1 root root 1544 Jan 1 18:02 shareinfo -rw-r--r-- 1 root root 135 Jul 15 2006 shareinfo.bak -rw-r--r-- 1 root root 0 Aug 26 2005 timer_backup.cron -rw-r--r-- 1 root root 0 Dec 20 2004 timer_backup_folder -rw-r--r-- 1 root root 133 Jul 10 2006 timer_status -rw-r--r-- 1 root root 0 Dec 20 2004 userinfo
Inside these files I could find a backup of the usual config files. Don't know if this a template to fill up the usual Linux config files with restored data again, or if this is only a sort of backup.
