Hi, We have implemented the rcp instruction generation for X86 target architecture. We have introduced a flag -fp-rcp flag which controls the generatation of X86 rcp instruction generation. We have observed minor effects on precision and hence hve put these transformations under the mentioned flag. Note that -fp-rcp is only enabl...

[Mod: This is a misconfiguration of a site. nobody''s uid should not be -1 -- alex] When playing around with rcp on Linux, we found something interesting, that we haven''t seen mentioned on bugtraq before: SUMMARY: Root privileges can be obtained by user nobody with uid 65535 by exploiting a problem with /usr/bin/rcp. Many applications are running as ''nobody'', in particular the NCSA...

I'd like to know a little about the internals of RSYNC. I am a little confused as to why RSYNC is using both the simple 32 bit algorithm and the MD4 checksum function on the same files. From my testing this causes a vast overhead that is clearly not represented by RCP (fairly obvious!). Removing checksumming from a secure whole-file LAN transfer brings RSYNC in line with the general performance of RCP. Can someone explain to me the rationale behind the checksum algoritm and use within the RSYNC protocol? I'm asking this question as I am finding it rathe...

Hi All, I am looking for SCP or RCP standards. I searched on the web but I am not able to find the standards. Please mail me the link where I can find the standards for SCP or RCP. Thanks, Abhijeet

I got used to rsync's -v --progress option so much that I used it instead of rcp even to simply copy files across the network. I dont like software that doesnt talk to me! :-) I like the percentage bar that --progress gives! To my surprise, I found that, when dealing with 1GB+ files, rsync is 4-5 _times_ slower than rcp. Yes, I know that rsync is optimized for sending delt...

IF ssh is a replacement for rlogin,rsh etc I can accept it respecting rlogin=false as rlogin does and rsh does not, however scp is a replacement for rcp, and rcp does NOT use rlogin attribute, so the implementation is NOT standard as scp fails if rlogin=false, but rcp succeeds, as documented. thanks mark

I've run into a situation where we'd like to replace rcp with rsync, but we've run into a difference in interface, which is causing us problems. Here's the problem. If we run this in rsync: > mkdir tmpdir; cd tmpdir > mkdir a; touch a/b > rsync -r a b/ > ls b a/ But for all the other programs, we get something different: &gt...

rcp -r is broken in 4.7 and 4.8. A fix is included below. The web-based bug interface is currently disabled so I can't open a bug report. I believe the person that provided the patch to me also indicated the problem exists in 5.0, but I'm unable to verify that since I'm only running 4.x....

Oh right. I think the NVIDIA blob executes those steps conditionally based on the upper bits not being 0x7ff (== infinity/nan). I should do the same thing here. [FWIW I was able to test the nv50 code last night and that one's a total fail for rcp/rsq... will need to port that over to my nvc0 and debug there.] On Mon, Feb 23, 2015 at 8:24 AM, Roland Scheidegger <sroland at vmware.com> wrote: > Does this give correct results for special floats (0, infs)? > We tried to improve (for single floats) x86 rcp in llvmpipe with > newt...

For what it's worth... 1. You cannot do a recursive rcp to a 4.9-RC1 machine. For example, "rcp -r somedir testbox:/tmp" fails. The attached patch fixes this. 2. Only the dial picobsd build will compile. The others (bridge, isp, net and router) all fail at various points. _________________________________________________________________ G...

...ces to internal data structures. I would appreciate any comments/suggestions regarding this direction. Directness is a plus ("No, that's a dumb idea" is fine, as long as a good explanation is provided). My hope is that as the Eclipse environment (especially the Rich Client Platform RCP and the Standard Widget Toolkit SWT) evolves, we can piggy-back on it and develop a free R environment that can compete with S-Plus in the GUI-oriented circles.
