Cannot read files from folder on another windows server

mukkollu has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to write code on Windows server A to read files from Windows server B. Here is the code piece.

$logdir = "\\\\Server\\e\$\\log";
opendir($fd, $logdir) or die "Cannot open directory: $!";
@AllFiles = readdir($fd);
print "$_\n" for @AllFiles;
[download]

This code neither throws error nor prints files. Files do exist in the log folder. I was able to view the files from windows explorer and command prompt from server A.

The only reasons I can think of why that might not work are: visibility; When you try it from the Explorer, you've previously done a Tools->Map network drive, but you haven't done the equivalent before running the script. permissions; When you run the script, it is running under a different account -- say a webserver id -- that doesn't have permission to access the network. What output do you see if you add the following to the top of your script: warn `net share`; warn `dir \\\\Server\\e\$`; ...

I did not map the network drive previously. I can list files using the below command `dir \\Server\e$\log` [download] I was using the same account on both the servers.	[reply] [d/l]

I have figured out a way to do this... @files = `dir $logdir \\| grep -i abc_`; [download]	[reply] [d/l]

Unless you've got a bug in your perl, your script works. I've run your script and all I changed was the machine-name. Strawberry perl 5.12.3 on an XP virtual-machine, connecting back to itself.	[reply]

If in doubt, print your variables. You're using double-quotes when making $logdir and I'm guessing $\ is being treated as a variable (it's line-ending or record-separator or some such iirc).	[reply]

I have printed variables and the $logdir string. I was able to access the logdir that was printed from command prompt to list files.	[reply]

No, «`\\Server\e$\log`» is indeed the string he wants to create. («`e$`» refers to «`e:`»)	[reply] [d/l] [select]
