Boot up "disturbing" messages

[Joseph Maxwell]

Hello,

On 'boot' I ahave been getting the following messages, perhaps they are
benign as the system eventually boots, but I am concerned about the
effects on performance & (in)efficiencies or even security

  1. May 28 02:37:15 machine1/kernel: bt0: Failed Intstat Reg Test
  2. May 28 02:37:16 machine1 sendmail[185]: My unqualified host name
     (machine1) unknown; sleeping for retry
     May 28 02:38:16 machine1 sendmail[185]: unable to qualify my own
     domain name (machine1) -- using short name
     May 28 02:38:16 machine1 sendmail[186]: starting daemon (8.11.1):
     SMTP+queueing at 00:30:00
     May 28 02:38:17 machine1 sendmail[220]: My unqualified host name
     (machine1) unknown; sleeping for retry
     May 28 02:39:17 machine1 sendmail[220]: unable to qualify my own
     domain name (machine1) -- using short name
     May 28 02:39:17 machine1 sendmail[220]: h4S9dHh00220: from=root,
     size=437, class=-60, nrcpts=1,
     msgid=<200305280939.h4S9dHh00220 at machine1>, relay=root at localhost
  3. An error message is generated ==> /etc/ssh/sshd_config line 57: bad
     config option: AllowTcpForwarding , which I had inadvertently set
     previously but removed, in /etc/ssh/sshd_config file actual line is
     "AllowTcpForwarding no",  but apparently the original option line
     is inserted somewhere else ????? an I can't find it to remove it.

Suggestions? Thanks
