Dear fellow Managers,

First of all, I would like to thank the following kind Sun Managers
for sharing their insight:

Rorz Chisholm
Stephen Harris
Casper Dik casper@holland.Sun.COM
Ronald Hello

The cause of my problem is that I had followed the Answerbook too
faithfully, so I had a nosuid in the /etc/auto_master. After removing
the option and restarting the automountd, everything worked.

Many thanks again to the four Sun Managers listed above.

Chin Fang

My original question:

>I have been trying to setup autofs for our FTP guest accounts, where guest
>is in the sense of wu-ftp guestgroup.
>Having setup such with NFS exported, hard mounted file systems many times,
>I don't think I am a novice anymore. However, no matter what I do,
>using statically linked ls or not, with freshly created dev files or not
>(chmod 666 too), anytime I tried to do a dir (or even ls), the dreaded
>425 Can't create data socket (,20): Bad file number. message
>showed up.
>Yes, I have all necessary dynamic libs available in the usr/lib in the
>guestaccount, etc/passwd, etc/group, dev/*, and of course, a *statically
>linked ls (which was verified to work using chroot on command line).
>However, I could never get a directory listing. The message comes from
>the ftpd.c in wu-ftpd distribution. I have hacked part of that code
>already. Before I spend more time on hacking the code again, I wonder
>whether there is anything I should be aware of?
