Re: HP-UX 11.x and Legato Networker 5.5

X-No-archive: yes

Hi James,

we are running Networker 7.1.3 on HPUX Itanium and beside the problem of
the non-existing persistent binding solution for tape devices it is
running well. Version 5.5 seems to be rather old, since 7.3.1 is the
current release. I am sorry that I could not help with your specific
problem but I would like to give You a link to a mailinglist where many
Legato networker users gave really helpful tips. I guess You will find a
helpful answer there. HTH

Hello,

I work for a company who uses Legato Networker to backup their HP-UX
systems.

The problem is Legato. It seems that on one particular server, Legato
wants to fail at least once a week. Multiple sites are supported
solely by me, and I have spent many weeks restoring Legato directories
when it crashes or encounters wierd problems, and then updating the
indexes and checking on the settings to make sure nothing has changed
(online and offline notes are kept on the settings for each server).

The thing that makes this difficult is that I am not allowed to install
software such as snort, sudo or tripwire. Furthermore, it seems that
although a limited number of people know the root password (i.e 1-2
people plus myself, as I am root), certain things are happening that
would require the root password. Physical security is not optimal, and
I have to sleep a small number of hours to keep my sanity, otherwise I
would be onsite or connected otherwise all the time.

A recent issue that concerns me is the numbe of times it's primary
daemons disappear from the process table, forciong me to go in and
restart it manually and watch the system. I had written a script to
automatically check and restart the processes, but it didn't work
correctly so it was removed from cron.

No signs of external intrusion are found, so it seems to me it would be
a system issue or internal access to the console for some odd reason to
only kill this application nightly this week.

Here is the script that was written:
#!/bin/sh
outfile="/nsr_up.txt"
touch $outfile
echo "Number of processes on host total: `ps -ef | grep nsr | wc -l`"
$outfile
ps -ef | grep nsrd
if [ "$?" -eq 0 ]; then
echo "Exit value of last command was unsuccessful" >> $outfile
/opt/networker/bin/nsrd
/opt/networker/bin/nsrexecd
echo "" >> $outfile
echo "NSR processes started at `date`" >> $outfile
echo "Number of NSR process running on host total: `ps -ef | grep nsr
| wc -l`" >> $outfile
ps -ef | grep nsr >> $outfile
sleep 1
fi
mailx root@myhost.ext < $outfile
mailx me@externaladdr.ext < $outfile
rm $outfile

Can someone point out why:
1. These Legato issues are occurring
2. Why this script is overloading processes (nsrd loads at least one
nsrexecd and two nsrexex processes when started)

Thanks.

BTW, the primary shell is /bin/sh.

No, it is the way that redirection is implemented within
a while (or any other) loop, that redundant syscalls are
slowing down the while loop itself.

The while loop (unfortunately) creates a new process
environment to execute the loop body, thereby
presumably copying the environment (and FDs)
multiple times.

Re: sed, remove last new line

quarkLore wrote:

Quote:

sed '$,$s/^.*$/whatever/' test
removes the last "line" not the last new-line character.

Well, it replaces the last line, but doesn't strip the newline
character, as would the equivalent:
sed -e '$s/^.*$/whatever/' test
sed(1) probably isn't the correct tool to use if one wants to strip
the last newline character from the last line ... unless it just
happens to be the case that one wants precisely nothing output in
place of that last line, in which case:
sed -e '$d'
will delete the last line.
Using awk(1) or perl(1) would easily handle removing the newline
character from the last line in the more general case, e.g.:
awk '{if(NR>1)print l;l=$0};END{if(NR>=1)printf("%s",l);}'
perl -e '{$/="";$_=<>;chomp;print;}'
If one wants whatever to replace the last line, including replacing
the ending newline with nothing:
awk '{if(NR>1)print l;l=$0};END{if(NR>=1)printf("whatever");}'
perl -e '{$/="";$_=<>;chomp;s/[^\n]*$/whatever/o;print;}'

And I'm not convinced this was even posted through aioe anyway.
That is not what the first part of aioe's path header customarily

You are right, it could be a challenge. However, in most cases you can
assume that the first public (routable) address in the list is the one
that is seen from the Internet.

This worked once but not now. It was probably removed due to excessive

Another interesting alternative. I guess this is a bit fragile because
it's dependent on the syntax of the current ftp for Linux.

#!/bin/bash
{
ftp -inuv <<eof
open ftp.proxad.net
user anonymous xx@xx.invalid
quote stat
quit
eof

Every question has an answer that is simple, obvious, straightforward, and ...

WRONG!

The whole point is that nowadays most machines are behind some kind of
NAT/firewall and so the "real" IP address is not the one that the
NIC is configured to.

To the OP: If you can FTP to somewhere, try "quote stat".

Since you're dealing with ls output, your fields are fixed length.

Modern versions of ls do not produce fixed-length fields; they
produce whitespace-separated fields. The actual width of any field
(except the last) is determined by the longest entry in the field.

Use substr to get the substring of $0 beginning at the first
character of $9 and print that rather than $9.

# Insert the values into the DB

Ok, I don't think anyone is going to re-write that script for you, but a much
better approach would be to do something along these lines:

echo "port $Port \n show post queue $Queue detail" |$SP_CTRL | while read line
do
case $line in
"Insert operations"*) ins_ops=${line##*: } ;;
"Update operations"*) upd_ops=${line##*: } ;;
"Delete operations"*) del_ops=${line##*: } ;;

... excercise in coding for YOU Smile

... add more logic to match all various values

esac
done

So, instead of relying on a "shifting" array, you grab specifically what you
want. Then, your INSERT statement can use the variables you define, and not
array elements, and you can eliminate the "if idle or not" logic...

Personally, I'd use perl or awk to parse this rather than ksh, but that's me :)
