Hi, the problem with PXE-Loop is solved. First of all thanks for all the comments. As a result of this I changed over to atftpd, because of the fact that we will install more than 200 clients via this system over night. The result is a small perl script which compares atime and ctime of the pxe-file. As soon atime is newer than ctime the file is deleted. This script will be run via cron/atd every 15 minutes. That's it, small and simple. :-)) The first approach was to monitor the /var/log/messages. But this wolud result in to much checks, before you whether the file has been served or not (date, client IP). The next thing would be that I never know how big this file will get. Who knows what ever and how much gets logged to that file ? :-) So I skipped that. The approach Anas tried is ok, but we have tftpd/dhcp on a different server than autoinstall. So his approach would not work. for a single server solution it would be ok. As soon I finished the script I gonna post it here. Anas if you like to put the script into the documentation you're welcome. (With a small hint to my person :-)). cheers frank +----------------------------------------------------------+ | Max-Planck-Institut für Radioastronomie | | Abt.1 (wissenschaftliche DV) | | | | Frank Pascher | +----------------------------------------------------------+ | Auf dem Huegel 69 Tel.: +49 (228) 525 359 | | 53121 Bonn Fax.: +49 (228) 535 229 | +----------------------------------------------------------+ | Email: mailto:fpascher@mpifr-bonn.mpg.de | | WWW: http://www.mpifr-bonn.mpg.de | | PGP Fingerprint: 13D1 8C86 57B3 2850 F158 4879 E5F3 7E20 | +----------------------------------------------------------+
