hi how can i do this in linux ubunt disabled NIPS protection (low and middle severity)
I have created an Ubuntu 18.04.4 server preseed file and I am attempting to use it with the 18.04.4 iso for a bare metal load.
In the boot string I am using auto=true and url=http://server/preseed.cfg.  I am able to read the file from the web server successfully bi a browser.
The loader starts and reads the preseed file successfully from the web server and then the loader jumps right to the interactive questions.

I have validated the file is good per multiple examples on Ubuntu’s site. I can find no reason that the preseed is not working as expected.  

Any suggestions would be greatly appreciated.
Dear All,

            we have a Sopho Server acting a proxy, and behind has a linux centos hosting a pac file, the reason we have this proxy server because taiwan office do not have their own internet access line, they use the internet access line from hong kong, and recently a user requested to access below website, and i found i can not access to this site with proxy enable, and i have added this URL to the pac file, but also seem not working, and if i put this site into the IE exception list, it could access, once the site put into exception list which mean do not use proxy server, if they don't use proxy server, which mean no internet access, just wonder how i can edit the pac file to allow this site to be able to access via proxy ? any help would be appreicated, thanks 


boot ko after bios _osi linux query ignored.

Hello all

I have a system that will not boot and just hang after the above message ( see attached photograph ) from an old ubuntu 14

I am pretty sure the issue is hardware since the os has multiple bootable oses and all of them hang somewhere after an acpi message. Tested with multiple linux and freebsd kernels. Not tested windows yet.

... and the laptop fell yesterday. It did work for s few hours normally afterwards and was cleanly shutdown without issues

My questions are

Do you happen to know what is the next step in the boot sequence ? I suspect loading graphic drivers but i am unsure and a dmesg output would help.

Do you happen to know some options i can pass the kernel in order to circumvent and go on with my work till i fix this ? I tried various combinations of noapic noacpi vga... i would be more than happy with a working command line and a vesa screen

Thanks for your time
I am on a RedHat Linux server.  I have a folder of files that files are being added to every minute or so.  I need a way to FTP these files to another server.  But I need to make sure that I don't try to transfer a file that is currently being written to.  I will be running the FTP script every 15 minutes or so.  What would be the best way to handle this?

Hi I am looking for some integration from jenkins to sonarqube scanner and similarly other tools like ansible, artifactory, Fortify on Demand etc. has any one worked or used these Tools integrations without actually installing plugins on Jenkins and integrated these tools with sonar scanner / cli for e.g: or else used any rest api to talk to these tools from Jenkins. If so could you please give a shout and if possible share any code references / links to demonstrate this and I will try get to you.

Out of all tools integration mentioned in question, priority is that i am looking at Jenkins - SonarQube integration with out using SonarQube Plugin on Jenkins.

I will be looking to set this up on Linux within a Docker image. Installing directly on CentOS is also an option.

Many Thx
I have a nifty piece of code that prepends timestamps to output. Is there a way to automatically feed every command I type into the code? I want to type any command, or script and get the timestamp prepended to the output without adding the code to what I type. Basically for everything I do I want a timestamp prepended to the output. Unfortunately getting another software like MobaXterm to handle the SSH sessions and logging is not an option.

Code: | while IFS= read -r line; do printf '[%s] %s\n' "$(date +"%Y%m%d_%H_%M_%S_%3N")" "$line"; done

> | while IFS= read -r line; do printf '[%s] %s\n' "$(date +"%Y%m%d_%H_%M_%S_%3N")" "$line"; done

I'm dealing with viral emails that are from different email addresses and networks but are using the same "display name".

I'm looking to see if there's a way to block mail by the senders "display name" not email address

The mail server is running Sendmail under Linux

I know I can setup procmail rules, but for those to work the message needs to be accepted for delivery, however the end goal is to block the message before it's accepted.

ClamAV does detect the messages and when it does they're blocked however when a new version of the infected file is used it takes a couple of days before an updated signature detects it.

Client PC's are protected with AV which is detecting and blocking however stopping them entirely would be nice.
