Aruba has a very traditional "admin" for user and password by default for many of its appliances. If you've reset or just got some new units this will be the default password that you should change immediately for security reasons.........

The reason we use the command below is because we need the md5sum value hash of the password. This means that we cannot use the md5sum Change "yournewpass" to the pass you want to set echo -n "yournewpass" | md5sum Then you get the md5sum hash of whatever you entered eg. in this case "yournewpass" 5a9351ed00c7d484486c571e7a78c913 ........

mysql reset root password. Oops I can't remember my MySQL root password! [root@centos7test etc]# mysql -u root -p Enter password: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) First we need to stop mariadb: systemctl stop mariadb Now we need to restart it with skip-grant-tables whic........

Most of us know the heredoc method but what if you need a basic query done repeatedly and manually while working from bash? It is a pain to manually type mysql and login each time. With this command below you can semi-automate those queries: echo "use somedb; select * from auctions" | mysql -u root --password="yourpassword" Just modify the above to suit your needs and you can add more queries by adding a sem........

In most of the Cisco router IOS I find the ports like ge0/0 ge0/1 and ge0/2 or whatever your ports are down. They will not even give you a link light. So one of the first tasks should be getting the port you are working with up. In my case the first goal is often connectivity with the LAN and WAN. LAN = your local area network (eg. in the office/home ) WAN= your ISP/public internet (eg. fiber/cable/dsl/ethernet).........

The commands below will help you reset any mysql user password. use mysql; update user set password=PASSWORD('thenewpass') where User='theusername'; flush privileges; The first line says to use the "mysql" database which contains all the user info. the second update line sets the new password "thenewpass" for the u........

This just simply outputs what you need a username and password that can be used to authenticate from .htaccess htpasswd -nb user password user:Gnb6uE9Lp4gt2 If you want to write it straight to a file htpasswd -cb /tmp/somefile.pw user password How To Use This In .htaccess AuthUserFile /tmp/somefile.pw AuthName GetLost!!

This is a common issue, what if a issue shouldn't have root but you want to use that user to make a full backup of a system? They of course need root access. You can actually just give them passwordless sudo access to rsync in /etc/sudoers: sudo vi /etc/sudoers yourusername ALL = NOPASSWD: /usr/bin/rsync Here is how you would execute rsync: The key thing for the remote host is to........

The solution is simple but strange, if you copy your /var/lib/mysql directory to another server and think it will work, be sure to check if you have /var/log/mysql and binary log files. If you do, the server will not work and will give you errors like below and crash without the proper log files. UPDATE user SET password=password("newpass") WHERE user='root'; flush privileges; ERROR 2013 (HY000): Lost connection to MySQL server durin........

I just realized I have some blank users which I deleted butI can still login to this dummy account without a password for some reason. mysql -u -p Welcome to the MySQL monitor.

This is very handy if you're too busy and don't have time to download whatever files you need. The -D specifies the domains allowed, this is because I specified -H which means foreign hosts are allowed, if you don't restrict them you'll end up going to the whole internet via ads and other links just like a search Engine would follow. -l 0 specifies to go deep, to as many levels as possible/as exist. -e robots=off is important because robots.txt often says you can't vie........

This is a great way to use your ftp server space, for example on your web hosting account (althoughI believe many hosts don't allow storage like this), but if you have a VPS/Dedicated Server etc.., this would be perfect. Imagine how easy it is to work with an ftp account that you can just mount as a normal partition or directory in Linux, it would be great for backups etc.. Name curlftpfs - mount a ftp host as a local directory Synopsis........

One note is to secure MySQL, I don't know for sure but I believe you could login to MySQL remotely with no password during this operation (I'm not sure, maybe it doesn't accept blank passwords but I firewall MySQL port anyway and recommend you do the same). First edit /etc/my.cf Under the [mysqld] field add the following line somewhere: skip-grant-tables Now restart mysql: service mysql restart or on Debian sty........

auth/auth_util.c:make_server_info_sam(840) User nobody in passdb, but getpwnam() fails! I never found the solution to this in the web, as usual so Ithought I'd post the fix. In plain English smbd is telling us that the user "nobody" does not exist in /etc/passwd. You can simply add this to your /etc/passwd file like so: nobody:x:65534:65534:nobody:/nonexistent:/sbin/nologin Now SAMBA/smbd should........

Server not using user level security and no password supplied. tree connect failed: NT_STATUS_WRONG_PASSWORD That happens when trying to use smbclient to connect to a share. The weird thing is that I can authnenticate just fine from Windows XP. It is partially my mistake, I forgot this share does have a password. I've tried authenticating with the correct user and also with "Guest" because this works in Windows. In Linux I ........

This will give you the basic info needed to browse and connect to Samba shares from the command line. From the GUI of Gnome or KDE etc, it is pretty standard and straight forward. However, I've found very little guides on how to do it from the command line and if you're like me, a nerd who prefers command line for its simplicity and for remote use, this is the way to go. First get a list of all the Samba/SMB shares on the target. smbclient -L hostname........
