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

Two possible scenarios:
- You are using VPN, but some of your applications time out (MTU is too big)
- Your OS is preconfigured for VPN by your employer, but the transfer rate can be better (MTU is too small)
In both cases the MTU needs to be adjusted:
- Start regedit
- Check all interfaces under HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces and find the one with the IP corresponding to the problem interface (e.g. the VPN tunnel interface). For example:
IPAddress REG_MULTI_SZ 192.168.12.1
MTU REG_DWORD 0x000005DC (1500)As you can see the MTU is set to 1500 what is too high for a VPN tunnel
- Double click on MTU
- Click on Decimal
- Enter 1400 (or 1300 to be on the safe side, or 1500 if you are not using VPN)
- Click OK
- Reconnect (if you are connected to the VPN)

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:
