Filename enocings
Hello everyone, I have run into the same issue which the fname-convert patch solves: http://rsync.samba.org/ftp/unpacked/rsync/patches/fname-convert.diff i.e. rsyncing between and latin 1 and utf-8 locales. First I'd really like to thank Eran Tromer for providing the patch as this fixes my immediate issue! I've attached an updated version which applies to the rsync-2.6.5 release and includes updates to proto.h. I must admit, I would have been fully pleased with a libiconv solution that merely interprets the file names in the character se...

MD4 checksum_seed
Hi, The following lines in compat.c are rather imprudent: if (read_batch || write_batch) checksum_seed = 32761; else checksum_seed = time(NULL); write_int(f_out,checksum_seed); Setting checksum_seed to a constant in batch mode means block collisions are reproducible and predictable. Thus, some files will be permanently "unlucky" in batch mode and will

Fwd: Re: setting checksum_seed
...://lists.samba.org/archive/rsync/2004-February/008616.html Earlier, I submitted a patch (against 2.5.6pre1 in Jan 2003) for --checksum-seed=NUM: http://lists.samba.org/archive/rsync/2003-January/004845.html Since I posted both of these patches, there was an interesting thread started by Eran Tromer about potential block checksum collisions that could be exploited by someone to trigger first-pass failures. See: http://lists.samba.org/archive/rsync/2004-March/008821.html The consequence is just a performance penalty, since with very high probability the whole-file checksum fails, triggeri...

...tics straight. For instance, the token sending functions now return the number of data bytes they read. A few things I wasn't sure about are marked by "#ET#". I hope it would be possible to incorporate this patch into rsync, after proper review and testing.

Understanding Problem with rsa min key length 1024
Hello, Sometime ago min rsa key length was increased to 1024 bit and i have a little understanding problem with this. I hope somebody with some crypto-experience can enlighten me. To make that clear, that is not about allowing lower keys in general. Personally i would tend to use even longer keys(2048bit+). However Due nature of RSA-algorithm in case of 1024bit this might result in a key

[PATCH] Batch-mode rewrite
Wayne, Please consider the attached patch. This applies to the current CVS, and is independant of patches/local-batch.diff. As a matter of fact, I'm sure it would conflict heavily with local-batch.diff. This version of batch mode has a couple distinguishing features: Write-batch records (almost) the entire sender side of the conversation into one file. ("Almost" because it has

RFE: create batch without patching
Hi, Currently, rsync --write-batch creates the batch fileset and also updates the destination. I suggest adding the ability to disable the latter. Motivation: I wish to sync two large but similar directories residing in different machines. There is a slow (dial-up) network connection between the machines, but I have physical access to both. Thus, I would like to create a batch fileset by
