: /lib/libc.so.4.2 has 755 permissions set on it.

ftp changes its root directory to /home/ftp. Therefore any program
you want to use must be in /home/ftp/bin and every library must be
in /home/ftp/lib. Soft links will not work because your root directory
will actually be /home/ftp.

: b) ftp using any other account name that exists does not work...
: it will ask me for a login, I type it in. It asks me for a

Most of us use shadow passwords, but ftp does not. I have been able to
ftp by manually placing the encrypted password into /etc/passwd. I do
not recommend this method because of security reasons, but it does
show that the problem is the lack of shadow password support in ftp.

: 3) I haven't tried out rcp and some of the other exotic command, but I
: seem to recall that rsh works fine and telnet seems to do pretty good.

rsh and telnet both function correctly.

: have heard that the problem still existed in 99p4 (from other people) and
: that it was even worse in the p4 verson... so I have chosen to stick with
: p3 for the time being. I am hoping that 99p5 will help? Is this a problem

: I really hope somebody has a clue...

PLEASE upgrade your kernel. You don't need to wait for SLS. Install
the kernel patches. MUCH has been done to the networking code. If you
follow the linux-activists NET channel, you will see that there is much
activity in trying to get the networking stable. There are big differences
between pl3 and pl5. I have seen much better behavior from pl5 than
any other release.
