Re: Segmentation fault

Shachar,

Thanks for this..

I love rsync, however the size of my backups now require me to sync my work=
 to=20
a NAS that is accessed by some really dodgy collegues. I needed an app that=
=20
applies encryption and keeps the directory\file structure. rsyncrypto is it=
=2E.

Both Redhat and Suse did not come with argtable.

post my email I discovered a site that had a simple line:
"openssl req -x509 -newkey rsa:2048 -keyout key.pem -out req.pem"
This meant absolutely nothing to me, but I applied it anyway.
then I applied
"rsyncrypto -r -c -vv tmp it-nas ./keydir ./req.pem"
and the backup worked..BUT not without the error\notice "gzip: unrecognized=
=20
option `--rsyncable'"

Without this I would have given up on the program.
Someone needs to put a simple example on sourceforge or hundred others are=
=20
going to experience what I have, and will give in.

The userguide on sourceforge is useless:
rsyncrypto <plaintext file> <cyphertext file> <key file> <certificate>
at the time I thought "what the hell is that ??"

Without examples of restoring on the web, I played around with a few comman=
ds,=20
trying to understand the logic of the syntax

To simulate a recovery I deleted the tmp folder then performed
i) rsyncrypto -d -r -c -vv tmp it-nas ./keydir ./req.pem
this did nothing
ii) rsyncrypto -d -r -c -vv it-nas tmp ./keydir ./req.pem
"gzip: stdin: not in gzip format
Decrypting tmp/test.jpg error: gunzip failed to run:"

I'm using gunzip 1.3.5.
Have you any suggestions on:
1) gzip: unrecognized option `--rsyncable'"
2) "gzip: stdin: not in gzip format
Decrypting tmp/test.jpg error: gunzip failed to run:"

I assume rsyncrypto fully works in debian. =C2=A0I would definately like to=
 see=20
this app work in Suse.

cheers
Shannon
