similar to: dangerous behaviour of scp

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'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: > cp -r a c/ > ls c foo > cp

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

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

Has anyone had a problem with scp not retaining ACLs set on the original file under Solaris 8? When I have a file that has ACLs set and I use scp or rsync -e ssh to copy the file (local->local or local->remote) the ACLs are gone from the copied file(s). Is this a known issue or am I just missing something (a flag for instance) when performing the copy? Thanks in advance for your help.

Dear developers, I discovered that directories created by scp when recursive copying into a sgid directory do not inherit the sgid bit. I believe this is a bug. A patch to fix this is attached.

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. _________________________________________________________________ Get MSN 8 Dial-up Internet Service FREE

If the source and destination file are identical, the receiving scp truncates the file. On the sending end, read() returns 0, and garbage is sent instead of actual data, and the receiving end puts it into the file, which at least confuses the users. -- Florian Weimer Florian.Weimer at RUS.Uni-Stuttgart.DE University of Stuttgart http://cert.uni-stuttgart.de/

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 deltas to a file

Hello, For some time now, our users have been encountering a problem when using scp to overwrite files on our mass-storage system, which uses SGI's DMF product. I don't have any data as to whether or not any other HSMs would be similarly affected. The scenario is that a user is overwriting a file (via scp) that has previously been migrated to tape. The scp opens the file for writing, but

I don't know if anyone would be interested in this but I'm including a patch to allow for offsets when transferring files with SCP. It's pretty simple and assumes the user knows what they are doing (for example, if transferring with a wild card the offset would apply to all files). -A is the number of bytes offset from the beginning of the files. -Z is the number of bytes inset
