Traceroute server: Status unsolved. The problem is the same on Pinger2. Johari talked to the network administrator at the centre about this issues and he suggested to talk to the security manager to check whether the firewall is blocking the icmp packer from the traceroute command (to do list). It is possible/probable that they are blocking the default traceroute UDP ports 33434 - 33465. If Johari has superuser privs on the machine he could try the traceroute -I to see if ICMP pings work, and -T -p 80 to see if TCP probes (SYN) to port 80 get  through OK.

Custom iso: He can get as far as the boot screen, but is unable to get to the desktop. They will started work on it  but student is still unable to boot ISO (9/17/2014). The student gave up , Johari needs a new student with more technical knowledge.

Research: there is Advanced Project (Master by coursework student working on the statistics of to look at the differences in the Raspberry teh data from teh raspberry Pi and the pinger machines production PingEr monitor at UNIMAS to see how much they differ.  

They are also looking at anomaly detection:  http://slac.stanford.edu/pubs/slacpubs/13250/slac-pub-13399.pdf or http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.363.1087 for comparisons of some techniques and http://people.cs.missouri.edu/~calyamp/publications/ontiTontimedetect_mascots10.pdf. Next they will look at perfromance among correlated routes. There are quite a lot of papers in this are so a literature search is highly recommended.

Saqib has root access to  the pinger monitor at UM. However IP address of hop 6 from UM to UNISAM is not pingable. thusThus he can't look at  time series of RTT to see if there are good and bad periods.
