Telent problem (and other commands)

Hi

We are moving from an old HPUX box to a new AIX box and are having a few problems with standard UNIX utilities on the AIX box.

Firstly telnet.

We have a script with the following code

telnet $Host 80 <<-EOF > $WebPageFile 2>$TelnetError
GET
EOF

The result in $WebPageFile is:

Trying...
Connected to 10.13.200.33.
Escape character is '^]'.
Connection closed.

What is expected is:

Trying...
Connected to 10.13.200.33.
Escape character is '^]'.
get HTTP/1.0 401 access denied
Basic realm=&quot;WebIntelligence (14:00:52 Mar 26 2003)&quot;
Set-Cookie: WebIntelligenceSession=EN572529E4QT17; path=/wi
status: 401
Content-Length: 115

<HTML><HEADER><TITLE>WebIntelligence</TITLE></HEADER><BODY onLoad='location=&quot;/wi/&quot;;' bgcolor=white>
</BODY></HTML>Connection closed.


Why will the output not appear. The problem is repeatable from the command line. However, if I enter telnet $Host 80 at the prompt and then manually enter the Get command, the result is as expected. Any suggestions, please.

The other problem was with &quot;time&quot; but I suspect this may be a problem with other commands. What I was trying to do is send the output of &quot;time&quot; to a file, eg.

[dmld01@amppsdmd1]DRIDMSPT:/home/dmld01/debug>time ls 2> myfile
avg_mem.sql free_space.sql longprog.sql sgachk.sql tr_r_f_update.sql
bindvals.sql hitratio.sql mincache.sql sqlcache.sql utlxplan.sql
buffercache.sql index_extents.sql monses.sql sw.sql what_sql.sql
cleanplan.sql indx.sql myfile sw2.sql xplain.sql
delplan.sql iobottle.sql no_space.sql tblsps.sql
disk_read.sql lock1.sql plsql_cache.sql test.sql
expplan.sql lock_user.sql readplan1.sql tmp.sql

real 0m0.01s
user 0m0.00s
sys 0m0.00s
[dmld01@amppsdmd1]DRIDMSPT:/home/dmld01/debug>cat myfile
[dmld01@amppsdmd1]DRIDMSPT:/home/dmld01/debug>

As you can see, myfile is empty while the &quot;time&quot; output is on the screen. If, however, I enter the full path to &quot;time&quot; the result is as expected

[dmld01@amppsdmd1]DRIDMSPT:/home/dmld01/debug>/usr/bin/time ls 2> myfile
avg_mem.sql free_space.sql longprog.sql sgachk.sql tr_r_f_update.sql
bindvals.sql hitratio.sql mincache.sql sqlcache.sql utlxplan.sql
buffercache.sql index_extents.sql monses.sql sw.sql what_sql.sql
cleanplan.sql indx.sql myfile sw2.sql xplain.sql
delplan.sql iobottle.sql no_space.sql tblsps.sql
disk_read.sql lock1.sql plsql_cache.sql test.sql
expplan.sql lock_user.sql readplan1.sql tmp.sql
[dmld01@amppsdmd1]DRIDMSPT:/home/dmld01/debug>cat myfile

Real 0.00
User 0.00
System 0.00
[dmld01@amppsdmd1]DRIDMSPT:/home/dmld01/debug>

Has anyone come across these problems and how did you over come them?

Many thanks
Martin

Worked out the &quot;time&quot; problem. There is a built in &quot;time&quot; function in ksh which works differently from /usr/bin/time. So, if you want to redirect the std err then you have to specify the path to use the correct &quot;time&quot;.

Now, if I could only figure out the telnet probelm!!!!!

I don't think the AIX telnet accepts here documents in the same way that ftp does.
I've always done this kind of thing using expect/tcl, but other options are:
1) use the kermit telnet which comes with scripting support.
2) use the perl net::telnet module.
3) rewrite your scripts to use a coprocess (only for the seriously wierd amongst us).

I think AIX telnet does accept here documents. Here is the same command entered manually at the prompt ...



[dmld01@amppsdmd1]DRIDMSPT:/home/dmld01>telnet 10.13.200.33 80
Trying...

So it does appear to accept the here document, just not where it's in a script!?!?!?!?!?!?!?!?!

martinfortmann - We appear to have a difference of opinion over terminology.

To me the here document is defined by the script, ie the code between << EOF and the EOF line whatever that code may be.

Hmmm, sectorseveng, not a difference of opinion - just that you know what you're talking about and I, well, don't *BLUSH*

Anyway, it appears that the telnet seems to execute whats in the here document (now that I know what that is *blush*) but just does not return any output. Most annoying.

Many thanks for the help in anycase. Some one here wrote a perl pseudo telnet using the socket library that gives us the output we expect.

Thanks again

Have found the solution. There is a -e flag under AIX telnet which overrides terminal-type negotiation. The session I had open was vt220 emulation. Using telnet -e vt100 made std out &quot;visible&quot;.

Just thought I'd let you know. Still surprised that it works when entered manually from the keyboard but not the here document.
