Hi all,
I am a newbie at Perl, nuf said there I guess. I have a need to move my log files around and I am using a simple perl scp script to do this. Now I need to add some error reporting to the script and I am in over my head. 1: I need to send an email when scp cannot connect to a server
2: I need to send and email if scp cannot find the file to download How can I get the error codes on a failure and what do I do with it? Please help me out if you can, I've been searching the web with no luck for 2 days. currently my scp command looks something like this: GET THE FILE WITH SCP
# $filetoget="$LOGFILEDIR/$f\.@FILEDOMAIN\$i\.$year-$mon-$mday"; $command = "/usr/bin/scp $a:$filetoget $f\.@FILEDOMAIN\$i\.$year$mon$mday\.$a";

Welcome to WebmasterWorld! A shot in the dark ... but I assume the scp man page will be a good place to start. [edited by: DrDoc at 6:55 am (utc) on Mar. 16, 2008]

I know you will be stunned but I've already done that.

[url=http://www.webmasterworld.com/forum19/2776.htm]welcome to WebmasterWorld[/url], wskibum! try testing and/or outputting the $! variable and see what you get.
you can print it in numeric or string context to see either the error number or the error string.

That sounds encouraging, how do I do that?

Actually, I think it is $? you need to check ... | scp exits with 0 on success or >0 if an error occurred. |

These are the only ones I was able to find:
1: General error in file copy
2: Destination is not directory, but it should be
3: Maximum symlink level exceeded
4: Connecting to host failed
5: Conneciton broken
6: File does not exist
7: No permission to access file
8: General error in sftp protocol
9: File transfer protocol mismatch
10: No file matches a given critera
65: Host not allowed to connect
66: General error in ssh protocol
67: Key exchange failed
68: Reserved
69: MAC error
70: Compression error
71: Service not available
72: Protocol version no supported
73: Host key not verifiable
74: Connection failed
75: Disconnected by application
76: Too many connections
77: Authentication cancelled by user
78: No more authentication methods available
