The problem is due to the bug in Solaris 2.6. Applying the patch 105786-01
(SunOS: /kernel/drv/ip) solve my problem.
The second problem can easily be solved be adding /etc/hostname.le0:1
See the original reply below.
I recently setup a multiple ip address for a unix box with Solaris 2.6 using
the following command manually...
ifconfig le0:1 188.8.131.52 up private -trailer netmask + broadcast +
Note that the 184.108.40.206 is for a totally different domain (says
some.org) and my current domain is uuuu.siu.edu.
The DNS entry for some.org which is sited on our dns server (say
220.127.116.11) contains www refering to 18.104.22.168. I also set
some.uuuu.siu.edu refering to the new virtual ip address in the dns entry
When I telnet to some other machine outside our domain, sometime my ip
address appeared as the ip address defined for le0, and sometime le0:1
dominates. I can tell this because the machine that I telnet to blocks
all the machine from outside the campus.
My question is that how can I hide my dns/ip address when I telnet to other
machine? i.e., using the ip address defined for le0.
Also, how can I setup the rc script so that the ifconfig is
automatically run when the machine boot/reboot.

To make the virtual interface automatically create an
/etc/hostname.le0:1 file with its name in it. The same
mechanism for setting up le0 automatically will be

I can't tell you why you connect through different ports, unless
perhaps you do not have a default router set in /etc/defaultrouter.
To make your ifconfig changes permanent, simply create a name file for
that interface -- in this case, /etc/hostname.le0:1 -- and put the
name in there and put the name and address in /etc/hosts.
Check the man pages.

Regarding your message, I too have a similar set up and have the same
problem. Just two days ago I configured my Solaris 2.6 SPARC system running
the latest patches as of March 1, 1998 and haven't found a solution yet.
The critical problem for me is remote authentication, which doesn't work
now. I'll pass on anything else I discover. Please summarize any solution
you come up with.

Not sure, but we're looking at that too. The machine alternates between

-rw-r--r-- 1 root root 17 Nov 18 16:32 /etc/hostname.le0
-rw-r--r-- 1 root other 17 Nov 24 10:30 /etc/hostname.le0:1
and put the desired hostname in each file. Then put in the correct
names and numbers in /etc/hosts.

There is a bug in 2.6 /kernel/drv/ip. You must get the updated file from sun
then use ndd to set ip_enable_if_groups in /dev/ip to 0.
