Hi there,
In a linux installation straight out of the box, I can cut-and-paste text from the mailer program (a stand-alone one called
XCmail), from an xterm or similar into elog with no trouble. I've not tried an image, I just attach them as I use plain encoding.
Don't know how it would work if it were on a properly secure linux box. |

I'm not sure, but I doubt that it would work under Linux. It's a general security issue: If your browser has free access to
your clipboard, then what happens if you for example copy-and-paste a password in some application, then forget your password
in the clipboard, then you surf to a malicious website, and a script on that site grabs your clipboard contents? This would
be a severe security hole on ANY operating system. |

Hmmm. Well, does that mean that it is easier under Linux? I have to confess I couldn't figure that out either. But
I'd be delighted to have Yet Another Reason to tell the users that "it works under Linux, maybe you should switch...." |

This is a limitation of the FCKEditor used inside ELOG, and actually of the whole browser concept under Windows.
There are some extensions to Firefox which let your paste an image as an attachment, but none for doing this right
into the text body. For some discussion about this have a look at
http://forums.developer.mindtouch.com/showthread.php?t=188
for example. |

No. The standard database engine inside ELOG works this way. It allows you to backup then every month or year easily just on the file system by copying all 10????a.log files for example. If you would have just one file (which could become very large), there is no easy way to do that. |

There was some sloppiness in the original patch--__USE_XOPEN wasn't defined, but worked when elog wasn't compiled alone. Now the appropriate ifndef/define statements are in elog.c
I have attached a possible patch--basically pirated from elogd.c Because strlcpy needed for the crypt cares about size, do_crypt needed the size, which had not been a concern for base64_encode in elog.c As a result, base64_encode changed slightly as well. I think the implementation places a limit of 32 characters on passwords, which seemed to already be the limit in elogd.c The elog.c limit appeared to be 80 characters. I tested both SSL and SSL+CRYPT for commandline elog entries with both a logbook specific write password as well as username/password combo in a password file.
AJC
I am in the process of setting up a new ELOG logbook. I checked out rev2280 from svn.savannah.psi.ch. I knew I wanted to encrypt passwords, so when I compiled, I used flags
USE_SSL=1
and
USE_CRYPT=1
I am running Red Hat enterprise linux 3, glibc-devel-2.3.2-95.50, openssl-devel-0.9.7a-33.25
Everything seemed to be working fine--I was able to set up logbooks using both a password file as well as write passwords and make entries to the logs. Then I tried to use the command line 'elog' to make an entry which failed to both logbooks.
/opt/elog/pro/elogd -c /opt/elog/pro/dansce_fancy.cfg -l Demo1 -w <mypassword>
Would change the password in dansce_fancy.cfg and I could make entries through the web interface, but
elog -h acouture -s -p 8081 -w <mypassword> -l Demo1 -a Author="Aaron Couture" -a Type=Routine -m Sampleinfo.txt -x -n 1
failed with
Error: Invalid user name or password
I got the same behaviour when I used a logbook with a user/password pair defined in a password file.
When I looked at the output from running elogd with the -v flag, I could see that everything was being received on the server side, but that the password did not agree with the write password in dansce_fancy.cfg
I then recompiled elog with
USE_SSL=1
USE_CRYPT=
And then the elog command line entries worked, both with write passwords and a password file (after recreating the password file and the write password). Looking at the elog.c source code, it appears that it does not know to use crypt rather then base64_encode when USE_CRYPT is true. elogd.c defined different behaviour if USE_CRYPT is defined.
Thanks,
Aaron Couture
