Hey folks,
I sent this to MAINTAINER, but never heard back, I'm sure he's
busy as hell.
The backups of my personal server at a remote colocation have
finally gotten larger than my DLT tapes, so I'm working on building
a "mirror" server to use rsync to keep a copy of everything. It's
a helluva lot cheaper than upgrading to larger tapes and tape drive.
I've created a passphraseless DSA key on my backups server,
and I've noticed some strange behavior with rsync... If I use
the passphraseless key and 'rlpte ssh' as the options given to
rsync, it works fine. If I add the -o and/or -g to transfer owner
and group, I get:
[EMAIL PROTECTED] /mirror]# rsync -rlptoge "ssh -i /root/.ssh/id_dsa_nopass"
[EMAIL PROTECTED]:/home fusion/
overflow: xflags=0x61 l1=0 l2=1006632964 lastname=home/benny [receiver]
ERROR: buffer overflow in recv_file_entry [receiver]
rsync error: error allocating core memory buffers (code 22) at util.c(122)
[receiver=3.0.2]
Hmmm. That's odd. So, I set up a DSA key with a passphrase:
[EMAIL PROTECTED] /mirror]# rsync -rlptoge ssh [EMAIL PROTECTED]:/home fusion/
Enter passphrase for key '/root/.ssh/id_dsa':
[EMAIL PROTECTED] /mirror]#
That was successful. I tried some more configurations, such as
archive mode (which is what I'm shooting for):
[EMAIL PROTECTED] /mirror]# rsync -aze "ssh -i /root/.ssh/id_dsa_nopass"
[EMAIL PROTECTED]:/home fusion/
overflow: xflags=0x61 l1=0 l2=1006632964 lastname=home/benny [receiver]
ERROR: buffer overflow in recv_file_entry [receiver]
rsync error: error allocating core memory buffers (code 22) at util.c(122)
[receiver=3.0.2]
[EMAIL PROTECTED] /mirror]#
And again without specifying the passphraseless key, which picks
up my normal key:
[EMAIL PROTECTED] /mirror]# rsync -aze ssh [EMAIL PROTECTED]:/home
fusion/
Enter passphrase for key '/root/.ssh/id_dsa':
[EMAIL PROTECTED] /mirror]#
Another success. So why, using the May 23 -CURRENT snapshot
and package version of rsync, does it hit a buffer overflow when
using a passphraseless key? I'd normally think it was hitting a
chain of symlinks or directories or something that was throwing it
for a loop, but just reverting back to ssh transport *with* a
passphrase makes it work as I would expect it to.
Can you help me figure out what's going wrong?
Thanks much!
Benny
