SSH Browser (Revision #45)

SSH Browser

Aqua Data Studio 11.0 features an SSH Browser that provides an overview of your Linux Server. The purpose of the SSH is to help you visualize and maintain your SSH Server. The SSH Browser in Aqua Data Studio v11.0 makes uses of procfs (or the proc filesystem), a special filesystem in UNIX-like operating systems that presents information about processes and other system information in a hierarchical file-like structure, providing a more convenient and standardized method for dynamically accessing process data held in the kernel than traditional tracing methods or direct access to kernel memory. Typically, it is mapped to a mount point named /proc at boot time. You can quickly view server version information, including: OS, CPUs, Memory, Disks, File Systems, Network Interfaces and the different Users. Currently this feature is not  supported in MAC OSX, but would be added in a future release.

The following different components of the Server can be quickly viewed: 

• OS
• CPUs
• Memory
• Disks
• File Systems
• Network Interfaces
• Users

OS

 The OS node displays the Hostname, Operating System, Kernel Name, Kernel Release, Kernel Version, Machine Hardware Name and Version Signature of the Linux Server.

CPUs

 Each core of the processor are displayed under CPUs. A dual-core processor will have 2 cpu's, a quad-core processor contains four cores, a hexa-core processor contains six cores. Each core is displayed as an individual node. The screenshot above is a Quad-core System.

Memory

The memory node displays the Memory information and the Swap space. The total memory, free memory, memory used, memory buffers, cached memory, memory user used, total swap space, free swap space and used swap space are the information that is displayed.

Disks

 Create a new Directory, Change Directory, List Present Working Directory and Delete Directory: 

Use the FluidShell prompt in Aqua Data Studio to execute Operating System commands -  \mkdir  [directory] command to create a new directory. \cd   [directory] changes to the directory, \pwd tells your present working directory and \rmdir  [directory] deletes a directory.

 Create a file, List your Files, Move, Copy, Rename and Remove: 

Use \touch  [filename] command in the FluidShell prompt to create a new file.The \ls command lists your files, \mv command moves your files from one directory to another, \cp copies a file, \rm deletes the file, \ren renames the file.

 Sync target and source Directories: 

You can syncronize a local target directory with files and subdirectories of source directory using \syncdir command.

File Systems

 Compress using zip, tar and gzip algorithms: 

FluidShell contains a collection of different algorithms to compress files.\zip command compresses and packs files into a single ZIP archive that is compatible with PKZIP. By default, packing a directory to a zipfile always implies that the subdirectories below should be included in the archive. \tar command stores/extracts files and/or directories to/from an archive file known as a tarfile. \gzip command reduces the size of named files using the GZIP algorithm. Each file is replaced by one with the extension .gz

 Uncompress archived file using unzip and gunzip: 

\unzip command extracts files from a ZIP archive to the named directory, or current directory if no directory specified. \gunzip takes a list of files and replaces each file whose name ends with .gz with an uncompressed file without the original extension

Network Interfaces

The network information are displayed under Network Interfaces. The received and transmitted packets and bytes passing through the network, errors, packets dropped, FIFO buffer errors, packet framing errors, compressed packets and multicast frames are captured under this node.

Users

The different users of the system are displayed under this node.
