Jumbo frames on Solaris

For e1000g (Solaris):
Change /kernel/drv/e1000g.conf to:

MaxFrameSize=3,3,3,3,3,3,3,3,3,3,3,3,3,3,3,3;
# 0 is for normal ethernet frames.
# 1 is for upto 4k size frames.
# 2 is for upto 8k size frames.
# 3 is for upto 16k size frames.
# These are maximum frame limits, not the actual ethernet frame
# size. Your actual ethernet frame size would be determined by
# protocol stack configuration (please refer to ndd command man pages)
# For Jumbo Frame Support (9k ethernet packet)
# use 3 (upto 16k size frames)

For rge (Solaris):
Maximum MTU supported by rge is 7000.
Change /kernel/drv/rge.conf to:

default_mtu = 7000;

Then reboot.

The result:

xeon# ifconfig -a
. . .
e1000g1: flags=201000843 mtu 9000 index 2
inet 10.0.10.1 netmask ffffff00 broadcast 10.0.10.255
ether 0:18:f3:ef:2a:d1

Short script for searching mail logs

Today I had to search through dozens of mail logs (syslog) located on several mail relays and find all entries related to a particular user.

Given:

  • All servers are managed via a remote tty console,
  • The ksh-script must be copy&pasteable
  • All logs are gzipped
  • I need all entries with the same message number (the ninth field) as the found log entry

This is what I came up with:

IOAT fatal failures

See I/OAT description here.

Solaris (at least snv_93 and and snv_95) panics if large amount of traffic is sent across the interface dedicated to a zone with exclusive TCP/IP stack. For example, start Firefox and forward the X traffic to the global zone.

“Completing post install setup”

If after entering username/password you see a small window (with a going back and forth blue “slider”) saying:

“Completing post install setup”

most likely svc:/system/postrun/default service is not running.

Check the status:

# svcs -vx postrun

and enable it if it’s disabled (for example, after a system upgrade)

# svcadm enable postrun

Related system packages:

# pkginfo | fgrep postrun
