Can you hit the GUI by using the IP address?

[comet424]

oh i also notice i can no longer  \\tower  in windows   so cant see files

 

i tried filezilla  and i cant access the mnt folders

failed to retrieve directory listings

 

hopefully the file i sent tells you something

First thing I'd try doing is boot into safe mode. 

 

If that doesn't get you anywhere, I would try deleting /config/ident.cfg from the flash drive and go from there.

[comet424]

how i boot to safe mode...  id have to get a video card  as right now the server is a headless  doesnt have a video card  

did the files show anything?

You can edit the syslinux.cfg file on the boot drive (click on it in the Main tab) and move the ‘default’ entry to the Safe Mode option.   Rebooting will then bring you up in Safe Mode.

[comet424]

how you click the main tab  since i cant get to the main page

 

i did rename the ident.cfg   file to !ident.cfg

i hit the reset button on the computer and let it boot back up...  still cant get to the main page  

i can still use filezilla to access the server..  still cant access the mnt folder

still cant \\tower   either...

i guess i need to install video card and then 

 

and i looked at the file all it shows in the file is " include /syslinux/syslinux.cfg"

it was located /boot/EFI/boot

 

so how do i make that boot into safe mode...  big problems when you have no video card on the server anything else i could do before i try to get a video card in the machine

The file you want to edit is in syslinux/syslinux.cfg - not the one in the EFI folder.

[comet424]

ok what do i edit in here..  and will this let me boot to safe mode and then i can telnet in.. or do i still need to do it on the computer.. as i mentioned no video card in that computer  

but here is the file 

default menu.c32
menu title Lime Technology, Inc.

label unRAID OS
  menu default
  kernel /bzimage
  append initrd=/bzroot

never thought i could bugger this up lol ugh as long as my files arent deleted on my hard drives and parity drive im ok

was fine till i tackled this rsync and some of it wasnt working...  

 

im guessing i gonna need to pull a video card out of another computer..  

[comet424]

if worse comes to worse and i have to format and install the usb  can i import a configuration file  that re imports the dockers.. my windows server vm  and such  like  Pfsense does  you save config and it loads it  

 

thats if you guys cant figure whats wrong 

[comet424]

oh and i tried rsyncing from the backup computer to the main unraid    and i was able to transfer files..  but i can not access the shares.. s

so unraid can see unraid shares  but  filezilla for mnt/    or the \\tower in windows is unaccesable.  so i not sure if that helps you guys figure what is wrong

 

 

[comet424]

so i plugged in a video card and monitor on the unraid computer and booted to safe mode no plugins no gui

and still get 502 error

 

 

[comet424]

if i run safe mode that has no plugins  but runs the gui  i log in..  i click the start button and click web interface... and just loads up fire fox and says sorry  we are updating it before you can use it thing and to click restart button on the firefox 

 

doesnt do anything else

[comet424]

now what is my next steps to fix it since im in safe mode

[comet424]

ok i fixed it

i re edited the go file and rem'd out the stuff i added.. but what is wrong with it.. i added this code from hoopster for rsync  but what is wrong with it??  or what should be fixed

#cd /root/.ssh
#cp /boot/config/sshroot/* /root/.ssh/
#chmod 600 *

##Setup drivers for hardware decoding in Plex
#modprobe i915
#chown -R nobody:users /dev/dri
#chmod -R 777 /dev/dri

## Copy SSH files back to /root/.ssh folder and set permissions for files
#mkdir -p /root/.ssh
#cp /boot/config/ssh/medianas_key /root/.ssh/id_rsa
#cp /boot/config/ssh/known_hosts /root/.ssh/known_hosts
#cat /boot/config/ssh/backupnas_key.pub > /root/.ssh/authorized_keys
#chmod g-rwx,o-rwx -R /root/.ssh

#!/bin/bash
# Start the Management Utility

Perhaps @Hoopster can offer some advice.

 

Didn't you delete /root/.ssh somewhere earlier in your monologue? If so, then

cd /root/.ssh

would fail and

chmod 600 *

would be applied to your current working directory and probably break a few things, making them non-executable. Surely

chmod 600 /root/.ssh/*

would be much safer.

[comet424]

because i know i was editing the go file that was in that notflash folder that wasnt even working lol

but i was reading also linustechtips  there article

so i might have used his and theres together...

 

so  unraid is very fussy  if something deleted  it breaks  is there no way for like a if file doesnt exsist  dont break the software  just report a warning in a log 

and with dislexia and all the stuff  i was reading to try to fix his rsync to fix mine.. like i need "tac"  program  to write to log files   and didnt wanna bug him always i try googling alot too  

 i might have mixed something up in the end

 

[comet424]

and ya i had deleted the ssh folder and uninstalled the ssh plugin and when i rebooted unraid thats when i got that 502 error

 

[bonienl]

Unraid comes with SSH built-in.

Why do you install another SSH application?

[comet424]

why would i know if unraid comes with ssh...

when i was reading to use rsync

you need to have cron ssh and one other thing installed..

like id know if ssh package installed...  and when i went to apps to search it said  ssh plugins  so i installed it..

and the cron i learned is installed too but it doesnt work  nor does the whats cron icon under ssh plugins

as i need to use this "tac"  command
