I have a VPS in hostinguer using Linux, and I have mounted an app. One of the functionality is that I have an endpoint that prints a file. The problem is, my local printer is not being recognized even though i have CUPS. * I have found solutions, but they apply to Windows VPS. Does someone have a possible solution for Linux? * I have tried this

-shellsession
    root@host ~# sudo ldadmin -p EPSON_L450 -E -v lpd://192.168.1.14/ENPQueue -m everywhere
    lpadmin: Unable to connect to "192.168.1.14:515": Connection timed out

* I also tried using drivers, with the same result, the IP is not found Is there anything I can do?

Key generated with key agent being asked several times (which is to give it only once) I am running a bash script to automate a backup on a NAS. I successfully generated a key (I had some difficulty as I had messed up the rights of the directory and file system which I resolved. The steps are in this question: https://unix.stackexchange.com/questions/757770/log-in-to-remote-server-by-using-a-generated-public-key) . In the bashscript (which I run from the local) I am creating a new directory on the remote before syncing the content of the same directory from the local. Each time a directory is created, I get asked the key

Enter passphrase for key '/Users/user01/.ssh/id_rsa':

Where user01 is the username of the local. Ok so the whole tree is the following:

/var/services/homes/user01/.ssh/

Here are the recap of the permissions of each branch are the following (with ls -ld and ls -la command (from bottom up): For the remote machine:

How is it possible to be able organize that I give (for instance) only once (the first time) the key?

I've been starting a web server process using nohup on a hosted Ubuntu 22.04.02 LTS VPS (virtual private server) to make it run in the background and keep it running even if the SSH session is disconnected. However, I noticed numerous times now that the process random stops at some point and I had to re-run it the next day. I'm pretty sure my process didn't crash since I'm using Java and on my local machine it runs indefinitely just fine. The same issue happened with a C++ process and again, locally it never showed any signs of crashes. Is there anything that could cause this issue and what would be the best way to resolve it? I assume it's not related to the hosting only since I have root access. I've considered using immortal to automatically restart the process when it died which worked but that's not an optimal solution, either, I just want the process to run indefinitely as expected.

I would like to download and install the latest *.deb*-package from github ( to be exact). How can I download the latest package (e.g. *otrverwaltung_0.9.1_all.deb*) automatically with a script from github? What I have tried so far: wget -O- -q --no-check-certificate https://github.com/elbersb/otr-verwaltung/downloads | grep -o -l -e 'otrverwaltung_[0-9.]*_all.deb' #The filename should be saved in a variable OTRPACKAGE sudo dpkg -i OTRPACKAGE

We have a PHP based application running on a cPanel server which saves tons of API log files (millions), and we are looking to have the PHP scripts be able to write the API log text files into another partition (Amazon EFS mounted to server), so that we can more easily move those text files around. The df-h output is below:

7.3G     0  7.3G   0% /dev
tmpfs           7.3G     0  7.3G   0% /dev/shm
tmpfs           7.3G  115M  7.2G   2% /run
tmpfs           7.3G     0  7.3G   0% /sys/fs/cgroup
/dev/xvda1      1.5T  623G  828G  43% /
/dev/loop0      3.9G  8.3M  3.7G   1% /tmp
127.0.0.1:/     8.0E  609G  8.0E   1% /smartefs01

tmpfs           1.5G     0  1.5G   0% /run/user/1005

The drive that we want to save the files to is located in /smartefs01, the actual PHP application resides in /home/user/public_html . We are struggling to find the easiest way to have the PHP application store files in /smartefs01 instead of /home/user_public_html. Since we want to be able to detach the drive and move it around with all the files on it in cases of changing servers etc. Let me know your thoughts! Kind regards, EC

On a CentOS-Bash shared hosting environment I host a website with a simple backend-frontend contact form with the PHP mail() function. Test emails can reach my Gmail account but if they do reach it at all (which is very rare), it takes much time, usually more than an hour. --- I understood from an infrastructure developer from my hosting company that this is because: * The emails are eventually sent from RANDOMLY_CREATED_USER_@us153.siteground.us which doesn't have valid DKIM, valid SPF, and SMTP authentication The infrastructure developer suggested that to solve this problem I would open an email account in my hosting environment and refer emails to there, so then I would indeed have valid DKIM, valid SPF and SMTP authentication. --- But say that I still want to refer emails to my Gmail account;
How to setup SMTP authentication for a backend-frontend contact form in a Linux environment (CentOS)?
Would that even be possible on a shared hosting environment (and then what about DKIM and SPF?)... ## Notes * Another problem added upon the one described above occurred with a second form which is a bit more complex than the simple test form in the base of this session;
The "From" => $email *header's email address* was my own Gmail address so an eventual sending from RANDOMLY_CREATED_USER_@us153.siteground.us was mistakenly grasped as *email faking* ("spoofing"), again, on top of the server mismatch described above

I never worked with Perl but in this community I bump time and again on recommendations to work with it, often as a "completion" for shell scripts. Is Perl a standard for *nix hosting companies?
For example, if my hosting provider provides me with SSH access but doesn't include Perl (rather, say, only PHP and Node.JS) should I leave this hosting provider? Thanks,

I’m stuck on a basic dns issue here "I think". I can send email but unable to receive. What I want to achieve is host webfiles of my webpage on 184.69.151.38 and use smtp ip from 193.47.34.77. I think my A records might be wrong. What is happening is mxtoolbox is picking up as the email server as 184.69.151.38 but the smtp is supposed to be sending from 193.47.34.77. *Likely* dns issue. I'm just not seeing it. Yet smtp test looks *decent*, not perfect but should work.

I have a Linux (Arch/Debian) with only a CLUI (Bash) and a server environment (LAMP) with the following details: 4 GB RAM 2 vCPU Cores 80 GB SSD 4 TB Transfer 40 Gbps Network In 4000 Mbps Network Out I host two websites (WordPress and/or Drupal) on each system. I want to backup and sync such a system live to my Windows Subsystem for Linux (WSL) but I don't want hourly/daily/weekly cron; I want that **every change in scope** of my system would be synced to a directory in my WSL. What I desire is very much like Google's *Backup&Sync* which I use in my Windows 10 / Ubuntu machines to prevent data loss in case a computer was unexpectedly and sadly ruined or stolen and formatted (in contrast to manual deletion of data after it was stolen where the data would be lost even in the remote syncing environment). My question is how to do such live syncing (like Google's *Backup&Sync*) from Linux to WSL? --- ## Side note This is how I backup manually so far and it's exactlly the process I desire to automate: cib() { # Create an Immediate ZIP Backup (of both $drt and DB); date="$(date \+%F\-%T)" mysqldump -u root -p --all-databases | zip "$drt/db-$date.zip" - # Note the hyphen before this comment; zip -r "${drt}/all_zipped-$date.zip" "$drt"/ -x "*/cache/*" "*/phpmyadmin/*" rm -f "$drt/db-$date.zip"

I am currently running a shared bluehost account. The current version of vim on the server is 7.2. I have recently installed 7.4 on my local machine and some of the features I've grown accustomed to are not available with 7.2. So, my question is: Is there any way to update vim on a shared hosting account? I did some digging and was able to successfully install python but have not found a way to upgrade vim.

I need to know how many number of accounts be hosted on a dedicated server with cpanel, with a HDD of 100 GB , and also max number of accounts, And also I would need assistance on "How I use a single same domain for multiple email servers "

Using the "SSH Shell Access" in my Cpanel I have added my public and private key in the import key section and I also have authorised them. But I am getting this "Connection timed out" error on port 22. I have WHM access. How can I solve this connection timeout issue ?

My Zabbix monitoring system told me that the uname output has changed on a virtual server (Host information was changed on ...). The ISP has shut down the entire server in order to perform some security patches on the physical hardware. How can it be, that the kernel information, which is received by the uname syscall, has changed after that? In my understanding, the patches pertain a completely different system layer and should have left the software OS VM layer untouched, isn't that so?

I have the following command set used to update all my WordPress sites in my CentOs shared-hosting partition on my hosting provider's platform (via daily cron). The wp commands inside the pushd-popd set, are of the WP-CLI program, which is a Bash extension used for various shell-level actions on WordPress websites. for dir in public_html/*/; do if pushd "$dir"; then wp plugin update --all wp core update wp language core update wp theme update --all popd fi done The directory public_html is the directory in which all website directories are located (each website usually has a database and a main file directory). Given that public_html has some directories **which are not** WordPress website directories, than, WP-CLI would return errors regarding them. To prevent these errors, I assume I could do: for dir in public_html/*/; do if pushd "$dir"; then wp plugin update --all 2>myErrors.txt wp core update 2>myErrors.txt wp language core update 2>myErrors.txt wp theme update --all 2>myErrors.txt popd fi done Instead writing 2>myErrors.txt four times (or more), is there a way to ensure all errors whatsoever, from every command, will go to the same file, in one line?

I have created a django website and instead purchasing a hosting service, i have hosted the website on my own PC having public IP. Hence now i can access my website through my IP address. Next step is to assign a domain name to my IP and hence everyone on internet can access my website through the domain name instead of IP. I know, there is a lot of sites for purchase a domain name but i don't want to purchase. Is it possible to run a dns server on my system or anyother system connected to internet and set up a domain name for my website so that it can be accessed on internet?
