I have several linux systems. Normally I login on them with my account, and after I login i execute sudo -s, so I can get admin privileges.
Sometimes I need to edit some files or copy some files out of the linux systems and in the past I ofter used the winscp program.
Unfortunately when I login with winscp with my account I don't have admin privileges, and thus I am not able to open and edit needed files, I am not able to copy files out of the system. Can you tell me how to login with winscp with admin privileges

Hi,

I have a linux based system where I incorrectly assigned the MAC address within U Boot.
Unfortunately "setenv ethaddr" is disabled in this version (Can't overwrite "ethaddr")

Is there an alternative way to remove this environment variable without using the standard command?

Any ideas would be appreciated.

Many thanks,

James

Hi there,

I copied the OS drive from the Azure environment as I want to work on a copy of the VM locally instead of in the cloud.  When I turn on the VM, it fails because it is trying to attach a data disk that I didn't download.  The data disk is 1TB so I don't want to download it just to attach it and not use it.  How can I fix this copied VM so that it only tries to boot and not look for this second drive?  I believe I can remove it by putting int he root password so that I can do some maintenance, but with Azure VMs, the root password isn't set and I don't want to change it just in case something happens on the live VM.   Is there another way around it?

I'm getting these errors:

fsck.ext4: Unable to resolve 'UUID=451a8a0d-0c99-4b34-8702-361627fda1a2a' [FAILED]
*** An error occurred during the file system check.  
Give root password for maintenance (or type Control-D to continue):

Thanks!!

How do I update BIOS on Centos?

I'm running Centos 7 on a Lenovo m83 and I can't figure out how to update the bios. I'm very new to Linux so if anyone can help me out I'd appreciate it.

I downloaded fbj9d1usa.iso from the site, threw it onto a flash drive, and now I can't figure out how to navigate to it or run it.

Hi Experts,

     I had build and run a docker image like this.

docker build -t harvest-trove:1.0.3 .
docker run --name trove_pull ${trove_environment[@]} -d -restart always harvest-trove:1.0.3 start pull                 

Select all Open in new window

I want to use docker compose for the above two commands

I had created the docker compose like this.

version:'3'
services:
   harvest-trove:
      build: .
      image: harvest-trove:1.0.3
      volumes:
                -  .:/home/trove
           env_file:
        -  web-variables.env
            command: python3 manage.py migrate
  trove-pull:
    container_name:trove-pull     
    image: harvest-trove
    env_file:
       - web-variables.env
       depends_on:
         - harvest-trove
       command: harvest-trove:1.0.3 start pull
       restart:always

Select all Open in new window

when I run docker-compose up I get the following error.


Please help me in fixing this issue.

With Many thanks,

Hi EE,

Trying to find the OS name of a very old version of Linux the two commands I have run are below:

uname -r
2.6.32-358.el6.x86_64

uname -a
Linux uch-crhotp-01 2.6.32-358.el6.x86_64

Any other commands I could run that could give the OS name and version?

Any assistance is appreciated.

Thank you.

How do you append the output value of a command  that is run plus the value of other variables to a log file in a bash script?
This is what I have just now

#!/bin/bash
host=$(hostname)
date=$(date '+%d%m%Y:%H%M)
log="installlogfile.txt"
runbinary  2>&1 | tee -a ${installlogfile.txt}  <- instead of this i want to be able to append also ${date} and ${host} to the installlogfile.txt but tee -a with multiple variables doesn't work. Any ideas on how to do this in bash would be much appreciated. If i echo or print the variables before i run the command there would be newline characters and I would like the output in the log file to be $(hostname) ${date} output from the command.

If you mean what I think you do, you can set up a .htaccess file to do this. In there, you can create a rule to redirect users to a specific url. So, if they type in www.yoursite.com it will redirect to http://yoursite.com

can I do this with my server
