===========================

Building the winrm-cli executable

You can build winrm-cli from source:

git clone https://github.com/masterzen/winrm-cli

cd winrm-cli

make

This will generate a binary in the base directory called ./winrm.

Note: you need go 1.5+. Please check your installation with

go version

Command-line usage

Once built, you can run remote commands like this:

./winrm -hostname remote.domain.com -username "Administrator" -password "secret" "ipconfig /all"

Summary : Kamailio - the Open Source SIP Server

URL : http://kamailio.org/

License : GPL-2.0

Description : Kamailio is an Open Source SIP Server released under GPL, able

: to handle thousands of call setups per second. Among features: asynchronous TCP,

: UDP and SCTP, secure communication via TLS for VoIP (voice, video); IPv4 and

: IPv6; SIMPLE instant messaging and presence with embedded XCAP server and MSRP

: relay; ENUM; DID and least cost routing; load balancing; routing fail-over;

: accounting, authentication and authorization; support for many backend systems

: such as MySQL, Postgres, Oracle, Radius, LDAP, Redis, Cassandra; XMLRPC control

: interface, SNMP monitoring. It can be used to build large VoIP servicing

: platforms or to scale up SIP-to-PSTN gateways, PBX systems or media servers

: like Asterisk™, FreeSWITCH™ or SEMS.

將 Oxidized 外掛上 Librenms

最近又有人在問我如何做 Cisco 或 FortiGate 設定組態 (configuration)

如何自動備份?

N年前我就有寫過類似的東西,只不過在當時我是用 Perl + telnet DIY小程式去做.

當然也是改成 Perl + ssh DIY 的小程式去做.但 N 年過去了,

目前已有太多工具可以逹成這個目地.

接下來的筆記是記錄,我是如何透過 Oxidized 去做這件事,

順便將其整合進 LibreNMS內,

當然只使用 Oxidized 也是 OK 的.

參考文件

http://blog.jason.tools/2021/02/librenms-oxidized.html

GlusterFS + Samba

最近有人問我如何建 DRDB ,但我之前沒留筆記,加這之前透過 google 很快的就建好了 DRDB

我只記得當初那個專案的內容為二台 CentOS 透過 Keepalived 去做 HA,DRDB的重點則用在 PostgreSQL 的 HA.

簡單的說就是做出 PostgreSQL的 HA (Active/Standby),供 Zabbix 使用.

而我最近則是使用 MariaDB Cluster去做 MySQL 的 HA (Active/Active),供 Librenms 使用,

HA 的 VIP 一樣是用 Keepalived.

但他的需求不是用在 DB 上,而是想去做 Samba 的 HA,但我想到的一個問題是,如果透過 DRBD 去做 HA 的話,會受限 DRDB 的機制,必然是一個 A/S 的架構,另一個問題是它是用 Block level disk replication,平時無法驗證檔案是否真的有複寫成功,除非 Remount replicated disk才可去驗證,或做 HA 切換演練去驗證.另一個問題則是 Active GG 後, A/S 的角色互換問題與重建.

假設 Active/Standby 的機器沒在監控它的 DRDB 機制是否運作正常?會不會有一天, HA 切換後才發現 Samba 的東西短少了!?

經過 goolge 後,發現 GlusterFS + Samba (CTDB) 這個組合比 DRDB + Samba 還要優一些,而且是 A/A 的架構

Byte-level file replication VS Block-level disk replication 我個人是比較推崇 GlusterFS 的.

以下為個人做的建制小筆記.

架構說明:
