I'm returning to VServer after being away from it for over a year. One
thing that worked previously and isn't working for me now is remotely
logging in via ssh. I see the following in /var/log/messages:
sshd[11932]: error: openpty: Permission denied
sshd[11932]: error: session_pty_req: session 0 alloc failed
I can reproduce the problem with a simple program that calls openpty.
The output from strace'ing it contains:
open("/dev/ptmx", O_RDWR) = 3
statfs("/dev/pts", {f_type="DEVPTS_SUPER_MAGIC", f_bsize=4096, f_blocks=0,
f_bfree=0, f_bavail=0, f_files=0, f_ffree=0, f_fsid={0, 0}, f_namelen=255,
f_frsize=4096}) = 0
ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig icanon echo ...}) = 0
ioctl(3, TIOCGPTN, [1]) = 0
stat64("/dev/pts/1", {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 1), ...}) = 0
statfs("/dev/pts/1", {f_type="DEVPTS_SUPER_MAGIC", f_bsize=4096, f_blocks=0,
f_bfree=0, f_bavail=0, f_files=0, f_ffree=0, f_fsid={0, 0}, f_namelen=255,
f_frsize=4096}) = 0
ioctl(3, TIOCSPTLCK, [0]) = 0
ioctl(3, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig icanon echo ...}) = 0
ioctl(3, TIOCGPTN, [1]) = 0
stat64("/dev/pts/1", {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 1), ...}) = 0
open("/dev/pts/1", O_RDWR|O_NOCTTY) = -1 EACCES (Permission denied)
Inside the vserver, /dev looks like this:
# ls -l /dev
total 0
crw-rw-rw- 1 root root 1, 7 Oct 3 08:15 full
srw-rw-rw- 1 root root 0 Oct 5 11:52 log
crw-rw-rw- 1 root root 1, 3 Oct 3 08:15 null
crw-rw-rw- 1 root root 5, 2 Oct 3 08:16 ptmx
drwxr-xr-x 2 root root 0 Oct 3 15:36 pts
crw-r--r-- 1 root root 1, 8 Oct 3 08:16 random
crw-rw-rw- 1 root root 5, 0 Oct 3 08:16 tty
crw-r--r-- 1 root root 1, 9 Oct 3 08:16 urandom
crw-rw-rw- 1 root root 1, 5 Oct 3 08:17 zero
What have I missed?
I am using kernel 2.6.12.5 with patch-2.6.12.4-vs2.0 and
util-server-0.30.208. The host's filesystem is Fedora Core 2 and the
vserver's FC4.
