A summary of encountered technical issues

Summary

Just a progress log of various issues we have on our table:
  1. Globus.
  2. UberFTP.
  3. SL6, glibc, RFC3484 (6724) and listening sockets.
  4. GNOME NetworkManager.
  5. Rogue RAs, RFC6104 and ramond.
  6. Conclusions, bigger picture.

Globus/GridFTP

FTP at large

In case your mind started objecting that IPv6 should be purely a transport issue let me remind that:
  1. Postel et al.'s RFC959/765 FTP is possibly the earliest service that implied the underlying IPv4 address structure in its PASV and PORT commands.
  2. These were "fixed" in RFC 2428 (Sep. 1998). For example:
    PORT 132,235,1,2,24,131
    becomes EPRT |1|132.235.1.2|6275|
    allowing EPRT |2|2001:123::200C:417A|6275|.
  3. Additionally, the Gridftp protocol includes commands for striped transfers (SPAS, SPOR), that do handle both address/port syntaxes in a possibly non-documented fashion.
