Fantastic New Docker appliance available on GNS3: Networkers Toolkit
This Docker appliance contains server side software for secondary management of network devices:
– www (nginx)
– ftp (vsftpd)
– tftp (tftpd)
– syslog (rsyslog)
– dhcp (isc-dhcpd)
– snmp server (snmpd + snmptrapd)
Thank you to Andras Dosztal @adosztal for this great appliance!
vsftpd, (or very secure FTP daemon), is an FTP server for Unix-like systems, including Linux. It is licensed under the GNU General Public License. It supports IPv6 and SSL.
vsftpd supports explicit (since 2.0.0) and implicit (since 2.1.0) FTPS.
vsftpd is the default FTP server in the Ubuntu, CentOS, Fedora, NimbleX, Slackware and RHEL Linux distributions.
Nginx ( /ˌɛndʒɪnˈɛks/ EN-jin-EKS) (stylized as NGINX, NGiИX or nginx) is a web server which can also be used as a reverse proxy, load balancer and HTTP cache. The software was created by Igor Sysoev and first publicly released in 2004. A company of the same name was founded in 2011 to provide support.
Nginx is free and open-source software, released under the terms of a BSD-like license. A large fraction of web servers use NGINX, often as a load balancer.
tftpd: TCP/IP command. IPv4 Trivial File Transfer Protocol server. in.tftpd is normally started by inetd and operates at the port indicated in the tftp Internet service description in /etc/services. Only publicly readable files may be accessed. By default, only files that already exist and are publicly writable can be written. In addition, if any directories are specified, access is restricted to files in those directories. The version of tftp described here is tftp-hpa.
RSYSLOG is the rocket-fast system for log processing.
It offers high-performance, great security features and a modular design. While it started as a regular syslogd, rsyslog has evolved into a kind of swiss army knife of logging, being able to accept inputs from a wide variety of sources, transform them, and output to the results to diverse destinations.
All IP devices need addresses, and ISC DHCP is the classic way to provide them. ISC DHCP is open source software that implements the Dynamic Host Configuration Protocol for connection to an IP network. It offers a complete solution for implementing DHCP servers, relay agents, and clients for small local networks to large enterprises. ISC DHCP solution supports both IPv4 and IPv6, and is suitable for use in high-volume and high-reliability applications. DHCP is available for free download under the terms of the ISC License, a BSD style license. (nb ISC DHCP will move to the MPL 2.0 license beginning with ISC DHCP 4.4.0)
ISC is developing a new DHCP server, Kea, which we intend to eventually replace ISC DHCP in most server implementations. We recommend that new implementers considering using Kea, and implement ISC DHCP only if Kea does not meet their needs. The Kea distribution does not currently include either a client or a relay.
snmptrapd is an SNMP application that receives and logs SNMP TRAP and INFORM messages.
Note: the default is to listen on UDP port 162 on all IPv4 interfaces. Since 162 is a privileged port, snmptrapd must typically be run as root.
