Linux Tutorial

This article is related to FTP programs, namely VSFTPD on RPM-Based, especially CentOS. Except for installation instructions must be adjusted to the existing Linux distribution.

Traditional FTP is generally not safe, because when you log in with your username and password the transmitted data is in text form, this increases the security gap which can allow the sniffing process on your network by people who are not entitled and with it’s easy to read the data you’re transferring. Therefore there was an addition to the new security for this FTP problem. Here we will make it easy for you to create/configure your VSFTPD server using OpenSSL encryption so that your username and password and even data files will be encrypted during the transfer.

Whether you need to enlarge or shrink a partition that is usually in “/” (slash root) format LVM or just troubleshooting your Linux system, you can use the following method to mount LVM partitions through rescue mode. following the steps:
Boot the system through the rescue CD media, and do a VG scan (volume group):

root@techsoftcenter ~]# lvm vgscan -v

Activate the existing VG () volume, group:

root@techsoftcenter ~]# lvm vgchange -vy

Melihat list logical volume (LV):

At this time we will implement one of the features of a Linux server, the FTP server. FTP servers, as we know, are one of the services on Linux that are more specifically for data exchange. In this article, we are building an FTP server with vsftpd on CentOS / RHEL / Fedora, where we will try to install and configure an FTP server with vSFTPD as its daemon, along with the steps:
Install vsftpd

System Monitoring

For some Linux administrators, the Linux server monitoring activity may be a definite need, because with the monitoring server, an optimal server where it has been fulfilled or not the resources owned by a server to support the distribution process.

Many of them still use the old way to collect their Linux system data, let’s call it the method of using sosreport in a Linux machine. Where the resulting data will be a lot and there is a need for the selection of data to be used, not to mention the creation of graph reports, so it is a little inconvenient and requires a long time for users.

In this share, I will share a little of my knowledge about the implementation of hard disk uses using scsi-target-utils and initiator-utilities in RHEL / CentOS / Fedora Linux OS. Where in making the ISCSI hard drive, later in the next article we will use it for High availability Cluster Web Server storage server. For the installation and configuration of the hard drive on RHEL / CentOS / Fedora, as follows:
