Grid5000 is un multi-site grid platform gathering 9 sites geographically distributed in France, Lyon currently have a 250 nodes grid, with the aim of 500 nodes for the year 2006.

• Proposition, installation et maintien du systeme d'information et de documentation actuel (Bugzilla, MediaWiki, ...), responsable éditorial pour celui-ci
• Unification des services web entre les 9 sites partenaires via un nommage unique
• Collaboration inter-sites sur les choix techniques à adopter
• Installation de services et mise en oeuvre de configurations complexes:
  • Servers: DNS, DHCP/TFTP, LDAP, NTP, SSH, apache, postfix
  • Monitoring tools: Nagios, Ganglia
  • Batch sceduler and deployemnt: OAR, Kadeploy
  • Database: mysql
  • Core network switches and routers: Extreme(BlackDiamond 8810), Foundry(EdgeIron), Cisco(Catalyst)
  • Firewall: filtering, proxy and NAT
• Assisting users (experimentation, demonstration, ...)

• Design and implementation in ruby of ZoneCheck v2, a tool to check and diagnostic DNS zone for correctness before their delegation.
• rewrote a DNS resolver in ruby to fit the ZoneCheck needs to interact with the DNS at various level (several level of APIs, use of UDP and TCP transport layers, ...)
• Design and setup of a website dedicated to ZoneCheck developement in an opensource model: http://www.zonecheck.fr/.
• Technical customer support for domain name delegation.

• Design and implementation of a Java active plateform dedicated to management. Prototype written in Java, final version written in C (due to the JVM inhability to kill threads).
• Administration and evolution of an experimental IPv6 platform:
  • setup and configuration of PCs under Linux/FreeBSD and SPARCS under Linux/Solaris, 8 computers being used as routers
  • configuration of a Cisco3500 switch (with use of VLANs) and a Cisco2600 router
  • setup of a DNS for the (internal) subdomain rlab.loria.fr
  • setup of NIS and NFS servers for managing user accounts
• porting the ANEP transport layer to iPAQ
• Networks teaching (60h) at IUT Charlemagne
  
  Networks teaching (35h) at ESIAL and participation in the drafting of the subjects.

• Implementation of the ANEP protocol over IPv4 and IPv6 in the Linux kernel; design of the socket interface (ANEP Socket) to access the protocol.
• Design of the Java interface to allow the use of ANEP directly from the JVM (JDKv6), and implementing it using the C/Java binding (JNI).
• ANEP MIB definition and enabling of ucd-snmp for ANEP.
• Administration and evolution of an experimental IPv6 platform (Linux/FreeBSD/Solaris).
• Design and setup of the initial version of http://w6.loria.fr/ (on an IPv6 enabled webserver).

• Enhancement and bug fixing in: NIS, NFS, FTP, libnsl
  • new functionnality in NIS
  • performance enhancement in NFS (kernel development)
  • Y2K fixes
  • memory leak fixes in multithreaded environment
• In charge of the SCO-ESIAL industrial project: slab allocator (memory allocator)
  
  organized meeting with the students, training on UnixWare and technical support during the project.
• Modem autodetection enhancement:
  
  design of the new autodetection scheme, and creation of the software developer kit.
• Source management:
  
  created a synchronisation tool between CVS and ClearCase to ease local development.

• Implementation in Java of shortest path algorithm to find the minimal cost of establishing a telephone line
• Access to the network topology by quering an Ingres database with a Jdbc driver
• Graphical interface based on Swing

• Analyse of the network topology and creation of an installation plan for the firewall.
• Developped a Perl parser to automate the filters writting for Cisco router IOS software.
• Setup of an FTP and HTTP proxy, and an S/Key authentication server.
• Writting of a document on the security policy in use.
