Hi, for some months now I do run pxe clients running 5.4-rel with no problems, with a 4.10-rel box as dhcp/tftp/nfs server. I just followed the strategy outlined in the handbook (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-diskless.html) . Now with the upcoming 6.1 release I cvsuppped the pxe-client to RELENG_6_0, build both kernel and world en installed it. He boots ok, but now sendmail does not run and also vipw does not run (it stucks with starting vi). I also observed I'm not able to open an files for the second time in a row while the first attempt succeeded (not with vi ofcourse). I tried to upgrade this pxe-client as well a few months ago in order to beta-drive RELENG_6 and the situation was the same. I then happened to compile vim on the box and that ran troublefree. But that was a quick test lasting an hour or so and without a running vipw. I doublechecked rpcbind, rpc.lockd en rpc.statd assumed they were not running. They were. I then decided to upgrade the pxe server running RELENG_4_10 to RELENG_5_4 to RELENG_6_0. That went flawless, but the pxe-client still behaved the same. Also, another pxe-client running RELENG_5_4 now was showing troubles with locking files as described above. Doing some research with cvs commits logs and cvsweb.freebsd.org I learned /usr/src/sys/rpc.lockd/kern.c was changed. I checked out version 1.13 and tried to recompile: that went wrong. As a second attempt, I plainly copied /usr/src/sys/usr.sbin/rpc.lockd/* from a RELENG_5_4 box to the client. That also did not make my compiler happy and broke before a usefull finish. I did not bother waiting for a make -k :-) Last week I tried to create a clean install (with the pxe-server still running RELENG_6_0 at that time) to make a installworld with DESTDIR=/var/pxe/client1, and make distribution and so on and pointed my "option root-path" in dhcpd.conf to that directory. The client did boot but was still showing the (presumed !) file locking trouble. Now I was thinking: Is there anyone here who IS running RELENG_6_0 pxe clients without the file-locking trouble I encounter over the last few months. Anyone who just can run vipw for three times in a row and where sendmail is just running. Yes sendmail starts but it does not display a banner and cannot be killed, netstat shows me it's not bond to any port. Can anyone point me to a solution, make a hint about where to look, what to check or do, or just give me the answer: "cannot be done with 6" :-/ I'm willing to test, patch or do whatever to make the thing work with 6 (time permitting ofcourse). Thanks for reading. paul
