How to sync data from Server to Raspberry Pi

by Rahul Mahale

Hello, I need to periodically sync the data to raspberry pi from Windows Azure. I can't use rsync as the data is on Windows server. Currently I am syncing the data by parsing the JSON API A python script extracts the links of physical files and then downloads the data. Script is scheduled to run using cron job. Is there any other way to Pull and Push data from Raspberry Pi to Server ? -- Rahul.R.Mahale. http://rahulmahale.wordpress.com/

Fail-Over & Load-balancing

by Siji Sunny

Hello All, We are trying to identify the right approach to do Fail-Over and Load Balancing in Linux server (Centos7), which contains Mariadb(mysql) and web-server (nginx) with some services such as Video On Demand, Games, etc. (streaming through Intranet, not Internet) Please guide, to select the right technology/solution (Ofcource OpenSource) to do so. Its seems complicated for me because of the dynamic data (eg: If a user watching video and fail over happens, he should get seamless streaming without interruption). I have considered HA-Cluster (Heartbeat) for Failover and HA-Proxy for load balancing, but still not sure, how to handle dynamic data fail over. -- Siji Sunny

Libreoffice 4.3.2.2 Writer -- loosing embedded images

by Arun Khan

A few days ago, I upgraded LO to 4.3.2.2 (amd64) on Linux and Mac OS X. In writer, while editing the doc with imported images (PNG), it looses some of the images (random) and shows a box with "Read Error" in top left corner. After closing the doc and reopening it, all traces of that image is gone! Seeing this problem on both Debian / Wheezy (amd64) as well OS X desktops. Anyone else experiencing this anomalous behavior? -- Arun Khan

How to bypass a domain in squid

by Rahul Mahale

Hello, I had set-up an proxy server on my raspberry pi. Raspberry Pi is a wifi hotspot running a dhcp on a subnet 192.168.5.1-255. all my LAN traffic goes through transperent squid proxy. I have one website hosted on Pi with Apache. I used bind9 to bind a local DNS with a website domain now the local website is available through LAN with abc.co.in domain but I want this site to be excluded from access.log or I want it to completely bypass the transparent squid proxy server. I tried following rules in squid3 but no success:- acl abclan dstdomain .abc.co.in http_access allow abclan always_direct allow abclan and this acl abclan dstdomain .abc.co.in cache deny abclan cache allow all but none worked and still access.log shows the abc.co.in entries. any suggestions to achieve this scenario ? Thanks! -- Rahul.R.Mahale. http://rahulmahale.wordpress.com/

Defining fixed IPs to VM Guests

by Joel A Divekar

Hi All I have setup a Centos7 host server with KVM and have created multiple VM running Ubuntu 14.04 using virt-manager. All VMs were having forward mode as "NAT" and using internal DHCP IP address 192.168.122.x series and gave them fixed ips based on their mac address. Now all these VMs are able to access Internet and able to run update on all these guest OS. But no server or devices on LAN / Internet is able to access these VM and I am running web and API servers on VMs. And as they have to be part of the Host servers IP pool, 192.168.1.x/24 network, I changed our virsh network settings from default to routed as <forward mode='route' dev='em1'> and struggling to configure fixed IPs for our VMs i.e Host 192.168.1.11, Web Server 192.168.1.12, API server 192.168.1.13 .... etc. Would like to do exactly as mentioned in this link https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/ht… Any help would be appreciated. Thanks.

Re: [ILUG-BOM] [Network] Need suggestion

by Rahul Mahale

Hello I have some success to my problem but their are few concerns, What I did :- 1.Installed Raspbian on Pi(B+). 2.made it as a wifi hotspot using hostapd and udhcpd. 3.installed the squid3 proxy server(apt-get install squid3). 4.managed the routing through Iptables to go all traffic through proxy. 5.made the proxy transperent. 6.wrote an python script to analyse the squid log (access.log) 7.the log analyzer counts the bytes used by each ip and dumps it in sqlite db. 8.the wifi clients who exceeds the limit are put in to one acl file blockedip. 9.from squid.conf i use the blockedip acl list to restrict the access. 10.after setting the cron job i am able to block clients after particular data usage. My Concerns:- 1.I am not able to bypass the one domain abc.com from proxy which should not appear in access.log 2. How can I increase the size of access.log to maintain the logs for more time as Pi has low storage. Any suggestions ? Regards:- -- Rahul.R.Mahale. http://rahulmahale.wordpress.com/

Ncomputing thin client and Ubuntu

by Ninad Gupte

Hi, Has anybody here tried getting Ncomputing L230 thin client to work with Ubuntu LTS? Though the Ncomputing website claims support for Ubuntu, and also provides a guide on configuring it, I have just not been able to get the thin client to connect to it. There are a number of guides floating around with slight variations, but none of them have worked for me so far. Regards, Ninad Gupte
