13 iseltime is a program that allows synchronizing the hardware time val‐
14 ues for RTC (BIOS Real-Time-Clock) and SEL (IPMI firmware SEL time)
15 with the OS system time. Run without options, iseltime shows each of
16 these times to show whether they are the same or not.
17
18 The OS system time should be in sync with the BIOS Real-Time-Clock.
19 The OS system time may also be kept from drifting via an NTP server.
20 Normally the BIOS will set the firmware SEL time from the RTC during
21 boot, but running this command may be necessary periodically if the
22 system does not reboot for a long time, for instance. Note that some
23 applications may not handle setting the time backward well. Note that
24 this command should not be run too frequently to avoid firmware timing
25 issues. It should not be set more than once per day.
26
27
29 Command line options are described below.
30
31 -s Set the RTC and IPMI firmware SEL time to match the system time.
32 This should not be performed more often than once a day.
33
34
35 -x Causes eXtra debug messages to be displayed.
36
37 -N nodename
38 Nodename or IP address of the remote target system. If a node‐
39 name is specified, IPMI LAN interface is used. Otherwise the
40 local system management interface is used.
41
42 -U rmt_user
43 Remote username for the nodename given. The default is a null
44 username.
45
46 -P/-R rmt_pswd
47 Remote password for the nodename given. The default is a null
48 password.
49
50 -E Use the remote password from Environment variable IPMI_PASSWORD.
51
52 -F drv_t
53 Force the driver type to one of the followng: imb, va, open,
54 gnu, landesk, lan, lan2, lan2i, kcs, smb. Note that lan2i means
55 lan2 with intelplus. The default is to detect any available
56 driver type and use it.
57
58 -J Use the specified LanPlus cipher suite (0 thru 17):
59 0=none/none/none, 1=sha1/none/none, 2=sha1/sha1/none,
60 3=sha1/sha1/cbc128, 4=sha1/sha1/xrc4_128, 5=sha1/sha1/xrc4_40,
61 6=md5/none/none, ... 14=md5/md5/xrc4_40. Default is 3.
62
63 -T Use a specified IPMI LAN Authentication Type: 0=None, 1=MD2,
64 2=MD5, 4=Straight Password, 5=OEM.
65
66 -V Use a specified IPMI LAN privilege level. 1=Callback level,
67 2=User level, 3=Operator level, 4=Administrator level (default),
68 5=OEM level.
69
70 -Y Yes, do prompt the user for the IPMI LAN remote password.
71 Alternatives for the password are -E or -P.
72
73 -Z Set the slave address for a local MC
