We have a mixed sun, netapp and freebsd nfs environment, and I have some freebsd machines that I can sacrifice to the cause. We are pretty desperate for working NFS file locking at work as well. FWIW, we tried the linux version of lockd on linux and not only did it suck potatoes, it was frequently the cause of that server crashing. I would stay completely away from it.

I was thinking about implementing SMP cpu stats using sysctl today and
I have a question - can I create sysctl nodes dynamically ?
i.e.
for (cpu = 0; cpu < get_num_cpus(); cpu++) {
/* create sysctl node here ? */
}
Also, one simple solution to maintaining per cpu stats is to put the whole
thing in struct globaldata. All existing code remains unchanged and
automagically updates the per cpu stats. I may need to add some additional
variables, which reflect system wide data. Now, if I put stuff in globaldata
and try to export it using sysctl, things get a little more complex.
One solution to the above problem is to use SMPpt relative addresses in
the sysctl declarations. But given that the number of CPUs is known only
at runtime, we come back to the first question in this mail.

Cast the second argument to (struct sockaddr *). i.e.
if (connect(s, (struct sockaddr *)&sin, sizeof sin) < 0) {

RTFM. "man cuserid" says:
DESCRIPTION
The cuserid function is made obsolete by getpwuid.
It is available from the compatibility library, libcompat.
So you need to add -lcompat to the command line, or take the manual
page's advice and use getpwuid (with an argument of geteuid()) instead,
and copy the pw_name member of the returned structure to myuser.

cuserid is in the compatibility library, from the man page:
CUSERID(3) FreeBSD Library Functions Manual
CUSERID(3)
NAME
cuserid - get user name associated with effective UID
SYNOPSIS
#include
char *
cuserid(char *s)
DESCRIPTION
The cuserid function is made obsolete by getpwuid.
It is available from the compatibility library, libcompat.
To get the program to link just add:
-lcompat

Try replacing that line with:
if( connect(s, (struct sockaddr *) &sin, sizeof(sin)) < 0) {
That should fix your `incompatable pointer' warning.
As regards to your link-time error (missing `cuserid') I'm afraid I
can't be of any help.

Hi everyone...
First of all I would like to state that IM not a programmer.
Im trying to compile a program and IM getting a errormessage, I have
included the error message bellow.
viking# cc emsg1.c

The software IM trying to compile is a network monitoring tool named
"EMU", I've found it at "http://www.jarrix.com.au".
At line 197 it looks like this...
if( connect(s, &sin, sizeof(sin)) < 0) {
close(s);
sleep(rand[count]);
count++;
}
else {
send(s, msg, strlen(msg), 0);
if(q_option) {
fp = fdopen(s, "r");
while ((c = fgetc(fp)) != EOF) {
putchar(c);
}
close(s);
exit(0);
}
close(s);
exit(0);
}
And where it complains about the "cuserid" bit it looks like this...
/* get my user name */
if (u_flag == 0) {
cuserid(myuser);
}
As stated above IM not a programmer and I would be most grateful for any
hints or suggestions.
Im attaching the emsg1.c file to if someone should get intressted.

cdrom speed adjustment ioctl
hello,
I've just hacked a new ioctl into the ATAPI cdrom driver, which
lets the user to specify (pronounce: ``slow down'' :) the speed
of todays' extremely high speed drives.
It's a documented ATAPI feature, and is very easy to implement,
and I've found it very useful :)
first, you need to add the ioctl into sys/cdio.h:
struct ioc_spdsel
{
int rate;
}
#define CDIOCSPDSEL _IOW('c',32,struct ioc_spdsel)
second, need to add this into i386/isa/atapi.h
#define ATAPI_SPEED_SELECT 0xbb
and finally need to add this case into the function ``acdioctl'' in
i386/isa/atapi-cd.c
case CDIOCSPDSEL:
{
struct ioc_spdsel *arg = (struct ioc_spdsel *)addr;
return acd_request_wait(cdp, ATAPI_SPEED_SELECT, 0,
arg->rate>>8 & 0xff,
arg->rate & 0xff,
0, 0, 0, 0, 0, 0, 0, 0);
}
of course unified diff's are available. i'm not an experienced
kernel hacker, please feel free to correct me and drop me
a mail about this thingy...
thanks in advance
