agetty IPMI serial console on RHEL respawning too fast

  • 772

I have a dell poweredge 2970 server with a serial console over ip enabled on the first ethernet.

The server with Red Hat enteprise 5.4 is configured to have console over ttyS1 in grub (console=ttyS1,57600 ) and in /etc/inttab I have:

S1:2345:respawn:/sbin/agetty -L -h ttyS1 57600 vt100

I can connect to console from another server using :

ipmitool -I lanplus -H myipmiIPaddress -U root -P password sol activate

but in the server I have /var/log/messages flooded with init: Id "S1" respawning too fast: disabled for 5 minutes.

If I remove the entry in inttab I can't connect anymore so I suppose it's not completely wrong, how could I avoid it respawing?

ipmi inittab

  1. securetty must not have the 'dev' part.Add just ttyS1. Also if the com port is shared between the system and bmc, change the mux setting to BMC from system. There is an ipmi command to switch port between system and bmc. (you can also do via Dell racadm)

  2. I have seen agetty respawning during sol, but it wont occur so often. Makesure you have added securetty entry and check whether if any firewall/selinux is preventing agetty.

  3. cfgSerial is for serial interface, also you have enable the user to access sol check cfgUserAdminSolEnable
