Sendmail

Syslog 沒有記錄任何東西;/var/log/syslog 為空

  • July 11, 2021

最近 sendmail 停止接受在我的 Solaris 10 x86 機器上傳遞的消息。我正在嘗試診斷問題,但係統日誌似乎也不起作用。我的 /etc/syslog.conf:

#ident  "@(#)syslog.conf        1.5     98/12/14 SMI"   /* SunOS 5.0 */
#
# Copyright (c) 1991-1998 by Sun Microsystems, Inc.

#
*.err;kern.notice;auth.notice                   /dev/sysmsg
*.err;kern.debug;daemon.notice;mail.crit        /var/adm/messages

*.alert;kern.err;daemon.err                     operator
*.alert                                         root

*.emerg                                         *

# if a non-loghost machine chooses to have authentication messages
# sent to the loghost machine, un-comment out the following line:
#auth.notice                    ifdef(`LOGHOST', /var/log/authlog, @loghost)
auth.info               /var/log/authlog

mail.info               /var/log/maillog


#
# non-loghost machines will use the following lines to cause "user"
# log messages to be logged locally.
#
ifdef(`LOGHOST', ,
user.err                                        /dev/sysmsg
user.err                                        /var/adm/messages
user.alert                                      `root, operator'
local7.debug                                    /var/log/mimedefang
user.emerg                                      *
)

/var/log/authlog 有效。/var/log/mimedefang 和 /var/adm/messages 也是如此。但是,/var/log/syslog 是空的,/var/log/syslog.0 中的最後一行來自一個多月前。/var/log/maillog 也是空的。我已經使用 svcadm 多次重新啟動系統日誌和 sendmail。我的 syslog.conf 有問題嗎?

正如上面@MadHatter 所述, syslog.conf 沒有在任何地方提及 /var/log/syslog 。因此,不會將任何日誌寫入 /var/log/syslog。

如果我沒記錯的話,大多數 Solaris 系統在 syslog.conf 中都有這樣一行:

mail.info                     ifdef(`LOGHOST', /var/log/syslog, @loghost)

或者

mail.debug                      ifdef(`LOGHOST', /var/log/syslog, @loghost)

或者

mail.info                     /var/log/syslog

我的 /etc/syslog.conf (andLinux) 包含

*.*;auth,authpriv.none          -/var/log/syslog

你發布的那個沒有提到/var/log/syslog。
