i have some perl codes for using ldap,but i don't know why don't work any error handling When i use msg->code for sample. an example:
[Code],,,,
In this case,if $msg->code return zero(or null) every thing work correctly but if it not zero don't give any message(eg."error result").What is problem?
I writed Quote:
#!/usr/bin/perl -w
use Error qw(:try);

I wonder how error handling is done in C in real applications, by returning a error code when something goes wrong, or by using setjmp and longjmp, or something else?

echo 'damn, there was an error'

I have a script that connects to a windows server, downloads a file, appends to it and then re-uploads the updated file. I want to implement error handling. An email is to be generated indicating whether there was an error or not. This email should include all standard and error output as a body. The current script looks something like this:
Code:
function Email_ServerSupport {
for time in once; do
echo "Subject: Billing - smb copy to accounting" $1
cat /tmp/smbx
cat /tmp/smbxerr
done | mail $EMAILADDR
}
/usr/bin/cp /dev/null /tmp/smbx
/usr/bin/cp /dev/null /tmp/smbxerr
cd /tmp
/usr/sfw/bin/smbclient $LOCATION -A $AUTHFILE >>/tmp/smbx <<EOF
get $OUTFILE
exit
EOF
cat $INFILE >> $OUTFILE
/usr/sfw/bin/smbxclient $LOCATION -A $AUTHFILE >>/tmp/smbx <<EOF
put $OUTFILE
cat /tmp/smbx | grep -v "Domain" | grep -v "putting file" | grep -v "getting file" >> /tmp/smbxerr
if [ -s /tmp/smbxerr ]; then
Email_ServerSupport " ERROR"
exit
else
echo "Transfer successful."
Email_ServerSupport " SUCCESS"
fi
The reason for the grep -v's is because, from my understanding, when using smbclient, ALL output goes to stdout, even errors. For this reason, I need to filter out lines including "domain" "putting file" or "getting file", all of which aren't errors. The problem is that even though the script seems to catch errors successfully now and then, the success email ends up blank (/tmp/smbx is somehow empty). I'm also worried it could miss possible errors I haven't tested. I'm thinking it has to do with the way "EOF" functions. Is there any way to capture output from the "put" and "get" commands? I can't simply redirect the output, can I?
I'm writing a Perl script to find an old key in a file and replace it with a new codefirst the program should find the old key in the input file. here is the way I used in my script. but it doesn't work.May you please let me know what is wrong and how I can correct it?the key is stored in the file in the following format:

Key=("1234567" , someOtherVrable)

View 5 Replies View RelatedI've been trying to get the ol' hello world script to run in a browser. From the hours of reading of various pages about this, I cant work out Basically I get nothing at all displayed.
the perl (test.pl):
#!/usr/bin/perl
print "Content-type: text/html
";
print "Hello, world!";
[Code]....
The output: Nothing. no error message either in the browser window or in the servers error log. If I change the path or the file name I get "invalid CGI ref" in the Cpanel error log.
I did get this to work for a brief time, then changed the Perl script and it stopped working. So I went back to hello world and havn't seen it work since. What is going on?
when I execute the command from the shell command line - it works and no error code.if I do the exact same command from a perl file - it fails with code 32512.the file is created from the same perl script that runs the command that fails. file permission is 0664.

I'm checking with a sniffer and there's activity going on between the client and the LDAP server... as a matter of fact, the sniffer shows that the search is producing one ldap item, however, php says it can't contact the ldap server (after it has bound and everything):
The script is working beautifully on another host with debian.
i have configured ldapserver on rhel4 for creating address book
following are configuration files on ldap server
/etc/openldap/slapd.conf
include /etc/openldap/schema/core.schema
include /etc/openldap/schema/cosine.schema
include /etc/openldap/schema/inetorgperson.schema
include /etc/openldap/schema/nis.schema
i am able to import this ldif file into database.also when i perform the ldapsearch on this server with command"ldapsearch �x �W �D �cn=manager, dc=example, dc =com� �b �dc=example, dc=com�" i get correct output.
but when i am trying to search from another client machine, i am getting "error ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)"
also when i configured address book on mozilla on server., it is working fine.but not working on another machine.is any configuration is missing on client machine.both ldap server and client are configured on rhel4es without any firewall or selinux.
I've been requested to modify a perl backup script we use which mounts a networked NAS machine. The actual mount command is called inside a system() command. In testing, I can do a test of the return value, so I'm able to tell whether or not I've mounted properly, but I can't make heads or tails out of the return on deliberate errors. (Such as mounting a non-existent box.) I'm displaying the returned value, which is 256 in my tests. The man page for mount listed error messages with values from 1 to 64, but no higher. Am I drawing this error value from the system command somehow? And what would be the best way to determine what this error means?
View 6 Replies View RelatedI took to yast to install ldap. I creating the CA cert, server key and server cert and specified them during the yast ldap server dialogs.
The firewall is open for ldap.
I also went through yast's ldap client ... though I didn't exactly see to anything (presuably it wrote up a configuration file somewhere).
However when trying use the basic ldap tools, like ldapwhoami. Well it doesn't connect and gives me the above error. Of coure the ldap db is unpopulated as yet, so it probably is not able to say who am at all. But ldapadd doesn't work either.
It seems to point to my SSL usage not being correct .. so I'm trying to double check that now.
I'm trying to set up a Linux server and I am new to this. I have gone through most of the configuration using SAMBA 3.0 and when I populate the ldap directory all I get this error before the password request:
Then when I perform an ldapsearch to see if the directory is populated I get this message:
I'm positive all my .conf files are done right.
I'm just starting out on a project relating to web search, to be done in C++. Which library should I use to help with downloading web pages into memory so that I can process them? The big thing is I want to be able to download the pages into variables/structures without actually putting them onto the hard disk.I googled and saw libcurl, but I was confused by some of the examples and wondering if this was really what I wanted.

During my read, "Code Complete",the author described the different ways of handling the ADT interface.He has wrote this passage:
Quote:
Option 2: Explicitly provide the data used by the ADT services. In this approach, you declare the data that the ADT uses within each routine that uses an ADT service. In other words, you create a Font data type that you pass to each of the ADT service routines. You must design the ADT service routines so that they use the Font data that's passed to them each time they're called. The client code doesn't need a font ID if you use this approach because it keeps track of the font data itself. (Even though the data is available directly from the Font data type, you should access it only with the ADT service routines.This is called keeping the structure "closed.") The advantage of this approach is that the ADT service routines don't have to look up font information based on a font ID. The disadvantage is that it exposes font data to the rest of the program, which increases the likelihood that client code will make use of the
ADT's implementation details that should have remained hidden within the ADT.
The problem is that it is a bit subtle in terms of coding for me. Can anybody give more concrete example, in working codes, especially in Java?
To parse several XML documents I'm using libxml++. I do programming for linux angstrom-armv5te. Because compiling libxml++ for this distribution and platform was impossible, I simply included the library to my project, which workes fine. Unfortunately I'm not able not use the exception handing which effects that a simple error inside a documents makes my whole program crash. This should not happen.
Is there a way to check the documents validity before parsing or better active the exception handling for doing this.
i had a problem with the find command in bash (which i deem is close enough to a promming language, if not please move this thread :P). i tried to reduce the command to the problem. i want the backticks, or $() for that matter; to be evaluated by -exec of find, not by bash. is that a caveat of find?
Code:
$ find testd -exec echo `basename {}` ; #confused me
test
test/a
test/b
[code]...
edit: i found out whats causing this. `basename {}` gets evaluated by bash before find is invoked, returns {} and `find . -exec echo {} ;" is run. now my question is, how to escape this eveluation from happening before.

Ubuntu Lucid amd64, mutt-1.5.20-7ubuntu1
I'm pretty sure the following used to work:
Code:
$ mutt mailto:url?subject="Whoop dee doo"
Now mutt exits silently with status=1. Tried setting EDITOR/VISUAL, no difference.
Edit: I had tempdir pointed at a non-existent directory in my .muttrc. Still annoying that there was no error message, but at least things are working again.
I have a system setup script for my Slackware installations that pulls all packages and source files from another machine and sets everything up to be identical between machines. The script works as expected but make it entirely unattended. How do I make the bash script deal with automatically selecting "Yes" for, for example "Install x(Yes/No): " when prompted by a make file?

I'm writing a perl script to remove a test database and part of that is of course getting rid of all files. So I wrote this to do the job:
Code:
This always results in an "Could not open /u00/app/oracle/product/10.2.0/rdbms/dbs for reading: No such file or directory" (that directory is the one ending with the $spfile_dir variable) message, although that directory exists and the executing user has writing rights on it.
The same behaviour if I create the directory array like this:
Code:
The problem does not occur when one of the directories is the only element in the array though. Of course I could copy and paste that part of the script for the second directory, but I don't like that workaround.
In a single main() function,so need signal handling. Use Posix Message Queue IPC mechanism , can ignore the priority and other linked list message,to implement the scenario:
