Hi Ethan,
In a recent bugfix (7045369) Mary noticed that the reason for the warning from
wget was that the hostname, not the IP address was included in the URLs for
downloading, e.g:
http://labtech-mpk-ai1:5555/export/aiserver/164-sparc//solaris.zlib
This occurred only where the AI server was multi-homed.
It is possible that this could also occur in this case? I'm not sure what the
contents of the wanboot.conf file was in this case, but I'd like to
double-check.
When the AI server is setup to serve multiple networks, the contents of
wanboot.conf will have something like:
root_server=http://narn:5555/cgi-bin/wanboot-cgi
root_file=/export/home/images/re_sparc_nightly/boot/platform/sun4v/boot_archive
boot_file=/export/home/images/re_sparc_nightly/platform/sun4v/wanboot
system_conf=system.conf
encryption_type=
signature_type=
server_authentication=no
client_authentication=no
Does the fix for 7045369 not work if a hostname is in the wanboot.conf file?
7045369 is fine, it's this fix that I'm wondering about since the changes you
have proposed - if wanboot.conf contains the hostname instead of the IP address
- then your fix here would set IPADDR to be narn not an IP address.
I don't know if this is an issue, or not, I just want to confirm it with you.
Ok, I get your question now. If it were a hostname, it is not an issue
because that hostname will be resolvable locally because of the
additional entry that will have already been put into the local
/etc/hosts file earlier by net-assembly. This is noted in the Eval of
the bug, but perhaps I could add a note into the block comment here.
Would the following NOTE help:
# SPARC clients extract the address of the AI
server
# from the root_server option in wanboot.conf,
which
# is in the following format:
#
#
root_server=http://<ai_server>:<port>/<path_to_wanboot-cgi>
#
# NOTE: the <ai_server> portion might be an IP
address
# or a hostname. For the cases where it is a
hostname,
# the local /etc/hosts file would have already been
# augmented with an entry to resolve that hostname.
IPADDR=$($GREP "^root_server" $WANBOOT_CONF | \
$CUT -d '=' -f2 | $CUT -d'/' -f3 | \
$CUT -d':' -f1)
As far as the variable name goes, I kept it as IPADDR because for the
x86 case, it's always an IP address and so didn't want to bother with
changing it.

Team,
Can I get a couple of reviewers for the following bugfix:
Webrev:
----------
https://cr.opensolaris.org/action/browse/caiman/equach/7093471/webrev/
BugID:
--------
7093471<http://monaco.us.oracle.com/detail.jsf?cr=7093471> wanboot without
DHCP
not working
Cases tested:
-----------------
1. Sparc, wanboot with DHCP, wanboot.conf has IP address in 'root_server'
2. Sparc, wanboot with DHCP, wanboot.conf has hostname in 'root_server'
3. Sparc, wanboot without DHCP, wanboot.conf has IP address in 'root_server'
4. Sparc, wanboot without DHCP, wanboot.conf has hostname in 'root_server'
thanks,
