Configure Ganglia Data Monitoring Agent (gmond) to send data to multiple Data Collection Agents (gmetad)

Posted on June 16, 2011 by Ahmed Tawfik

Edit the “/etc/gmond.conf” file, and just copy the udp_send_channel section, one copy for every host, e.g.

udp_send_channel {
host = 10.11.x.x
port = 8649
ttl = 1
}

udp_send_channel {
host = 10.11.x.y
port = 8649
ttl = 1
}

udp_send_channel {
host = 10.11.b.z
port = 8649
ttl = 1
}

Installing a Text-based Browser on AIX (Lynx)

Posted on June 14, 2011 by Ahmed Tawfik

If you want a very simple text-based web browser in order to test responses on an AIX server and don’t want to waste time and bandwidth using Firefox – if it exists – and an X-session, use “Lynx”, Here are the steps in brief:

  1. Download the RPM from IBM’s AIX Linux Toolbox. (search for “lynx”, it’s less than 1 MB in size)
  2. Install it “rpm -ivh package_name.rpm“
  3. Run it using “lynx url“, e.g. “lynx http://www.yahoo.com”

Enjoy!

How to overcome NFS through firewall issues using NFS4, while maintaining compatibility with NFS3 clients (Draft)

Posted on June 8, 2011 by Ahmed Tawfik

NFS4 server uses port 2049 only, no port mapping

Run “startsrc -s nfsrgyd” on client and server

Must use public file system, list the available using “nfsd -getnodes”, or else you’ll get an error indicating “No such filesystem or directory”

Can export for version 3 and for version 4 simultaneously (2 versions of the same export), Windows services for Unix seem to support only V3
