Thank you Chuck for the suggetion; here's the ping response from three
different servers:
HP Unix server
# ping ip 1480 -n 3
PING ip: 1480 byte packets
1480 bytes from ip: icmp_seq=0. time=0. ms
1480 bytes from ip: icmp_seq=1. time=0. ms
1480 bytes from ip: icmp_seq=2. time=0. ms
----ip PING Statistics----
3 packets transmitted, 3 packets received, 0% packet loss
round-trip (ms) min/avg/max = 0/0/0
Solaris server:
# ping -s ip 1480 3
PING ip: 1480 data bytes
1488 bytes from ip: icmp_seq=0. time=1. ms
1488 bytes from ip: icmp_seq=1. time=0. ms
1488 bytes from ip: icmp_seq=2. time=0. ms
----ip PING Statistics----
3 packets transmitted, 3 packets received, 0% packet loss
round-trip (ms) min/avg/max = 0/0/1
FreeBSD server:
# ping -s 1480 ip
ping: packet size too large: 1480 > 56: Operation not permitted
Any ideas?
Regards,
Joe

Subject: Question about expr
To: freebsd-...@freebsd.org

Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hello all,
I am used to the normal GNU-version of expr (also available on Solaris)
and much prefer it over the FreeBSD version. The GNU version allows
internal commands like length, substring and others which make it much
easier to work with. Is there any way I can replace FreeBSD's native
expr with the GNU version ? Since I believe expr does not normally ship
as a shell-builtin, I don't think the shell can of much help in the matter.
Actually, I think it might not be a bad idea to place a port of GNU-expr
in the ports directory. This would allow a lot a scripts to be readily
portable to multiple environments.
Thanks for any help.
Regards
Manish Jain

gconf-editor changes the settings of the current user, the gdm settings
are global (system) so should be changed by root or the user gdm is
running in.
I don't currently have gdm on any of my systems but AFAIR there is a gdm
user created for running the greeter. You should be able to change the
disable_user_list setting for this user which will have the desired
effect. Something along the lines of this blog post
http://lionlix.wordpress.com/2009/11/07/hack-ubuntu-9-10-disabling-userlist-in-gdm-login-screen/
should work.

It's part of the coreutils package. If you install the sysutils/coreutils
port, you can symlink /bin/expr over to it (or make a copy). I don't know
if it's 100% compatible with BSD expr, though, so you may end up breaking
scripts in the base system.

Hello Dan,
Thanks for the info. But I don't intend to symlink /bin/expr over to it.
Instead I'll just create an alias in bash's profile and my scripts.
That should let core scripts execute with /bin/expr and my scripts to
use the GNU-version. Which actually leads me to second question :
When you execute a script, it will automatically pick up the exports in
.bash_profile. But even if you manually source bash's profile at the
start of your script, only the exports get picked up and the aliases are
ignored. Is there some way to fix this so that I don't have to set an
alias for expr at the top each time I write a script ?
Thanks & Regards

Hi:
I have been searching for the appropriate perl mailing list, but no
avail. I'm trying to build a database with Berkeley DB and MLDBM for a
multi dimensional hash structure,
my $hdbm = tie %host, 'MLDBM', -Filename => "$dbdir/host.db",
-Flags => DB_CREATE|O_RDWR
or die "Cannot open database '$dbdir/host.db: $!\n";
but I have some problems:
I can read entries and create new ones, but I can't update existing
entries.
And I have a problem untieing cleanly:
untie attempted while 1 inner references still exist at
bin/smtp_reject.pl line 175.
untie attempted while 1 inner references still exist at
bin/smtp_reject.pl line 176.
Any hints? or which mailing list should I post to?
Thanks, Erik
