These errors are usually caused by the lack mysql client dev files If using mariadb install this: apt-get install libmariadbclient-dev If using mysql install this: apt-get install libmysqlclient-dev........

The passwords are stored in the following locations on Unix/Linux: The directory is usually inside your home like this: ~/.mozilla/firefox logins.json contains the locations, username and password key*.db (usually then name could be key3.db or key4.db) Without the key file you will not see any passwords in Firefox as it is required to in order to decrypt the contents of logins.json........

These types of errors are normally caused by misconfiguration of your /etc/apt/sources.list. In this example on Debian 10, if you didn't complete the install correctly, you will have no repos enabled and only rely on CDROM. "Package wget is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source. E: Package 'wget' ha........

The Linux Mint team has disabled it by setting an apt preference, you can edit or just remove the file: sudo apt install snapd Reading package lists...

The Linux Kernel interpretated a very high volume of real traffic as a DDOS attack so it basically ends up blocking your web server. possible SYN flooding on ctid 42131, port 80. Sending cookies. Simple fix edit sysctl values for max_syn_backlog sysctl -w net.ipv4.tcp_max_syn_backlog=5000 To make them permanent edit /etc/sysctl.conf echo "net.ipv4.tcp_........

gpick is a great and simple tool now that I now how to use it sudo apt-get install gpick The trick is to find "the swatch" I was in a rush and was frustrated that it wouldn't work how Iexpected and I had to memorize the hex code of the color my mouse was over. There is something it tells you to do which is "Click on the swatch area" (click onthe honeycomb graphic area that is the s........

There are usually two reasons for this. #1 The most common is that you need to enable the -r (recursive) flag with zip to make it recurse into directories. So the solution is to use -r zip -r somefile.zip yourfiles #2 If you are using bash scripting based on ls without the full path or for some other reason the full path is missing, zip looks for the files in the current directory so this will always fail.........

The solution is simply "tidy"/Tidy-HTML. It will take your poorly formatted HTML code (and I mean files that span just a few lines that are unreadable) and fix it up. Note the command below does everything in place. *Make sure you take a backup of all .html files* It also seems to break html5 code/templates so beware. tidy -im yourfile.html An automated way in bash:........

The "passwords do not match" implies or makes it appear that your auth code is wrong but actually you have to click "View additional settings" and then see there are 2 password fields to manage the domain once it is transferred (the password is typed twice for confirmation). Simply fill out a password twice or remove the first password fields contents and all will be well.........

The only way I've found in mdadm to make 2 drives perform like a proper RAID 1 (eg. the read speed should be 2x that of a single drive) is to use the --layout=f2 (far 2). mdadm raid10 performance issues. Be very aware that mdadm seems to default to layout=n2 (which means near). In this scenario it means it is like mdadm RAID 1 performance (you get maximum read speeds of a single drive). dd if=/dev/md126 of=/dev/null bs=1M cou........

The first thing to diagnose is what is actually in the database (use PHPMyAdmin or CLI). You will of course either find that the backslash is either in the database or not. If the backslash is in the database you probably have magic quotes gpc/runtime on and/or are calling the "addslashes()" function which does this. If you are escaping your data with mysql_real_escape_string() then think again, you probably have magic quotes gpc enabled either in php.ini or........

The location of the hash is stored in the configuration.php file and is really a bit of pain to have to pull out everytime but this is how WHMCS stores its encryption key hash to see the full credit card number.........

The Cause Basically it's usually because your Cpanel has new IPs and the old IPs it knows are no longer available/working/valid. The solution is to change the site's IP but you may run into issues for various reasons. Here is what I encountered below. It redirects there even though public_html is empty and doesn't have any index or htaccess redirect. --- This issue happened after a CPanel migration, the site is bein........

The solution is simple but it's a wonder why VBOX doesn't address it directly? Perhaps newer versions will but you have to add your user to the "vboxusers" group and then login and logout and you'll see the devices you wanted but couldn't access are now available. The weird thing is that the grayed out issue doesn't happen with all devcies but one notable thing is the Apple iPhone especially in DFU or Recovery Mode which is an big issue for some people.........
