Hello! for the first, I’m not a linux guy:) i have a script. this script copying file by rpc. last time file copied 1 month before. and now i cannot copy new file. rcp starting to copy, it copies 540Kb and than it stuckes (connection timeout). cannot find anything in logs about it. (suse linux 9 on both servers) So can you help me, where should i search the problem. What it can be? btw network configuration never changed. thanks in advance! ## – andrey\_gorohov andrey\_gorohov’s Profile: [http://forums.novell.com/member.php?userid=118711](http://forums.novell.com/member.php?userid=118711) View this thread: [http://forums.novell.com/showthread.php?t=447281](http://forums.novell.com/showthread.php?t=447281) ---

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 rcp is pretty old… in fact, ancient, and insecure. You really should be using scp for any file copies as it adds security and works out of the box on SLES (since SSH is enabled by default on SLES). Perhaps rcp actually uses scp these days, but I’d still use scp explicitly since sending data unencrypted across the wire is generally a bad idea. Is this an option for you? If not, get a LAN trace of the connection and see which side is not continuing to send data when it should. A lack of acknowledgement from the server could stall the client, or just leave it retrying things over and over. A lack of continuing the stream from the client could also stall things. Good luck. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (GNU/Linux) Comment: Using GnuPG with Mozilla - [http://enigmail.mozdev.org/](http://enigmail.mozdev.org/) iQIcBAEBAgAGBQJOpo+3AAoJEF+XTK08PnB5NdcP/1avDqpW5s+A6IYlTeXkT3RE lkmxl5CfKkDRiIWrJujhgO2inuZyF1fIylFGqObWMCi1LXCyWWwSP5fKoR/rvFik 3qGWiXCSgdn6e5cLUs1p4JHzZ4z5VGSvw1QBUeevBIAZXwjqAPTfP4tJTf0Biucv TRwHZT76RRF1sfcLtblX+MWknx923FybJ7GyyZ80zecur7tTniOMzjGcfPrzJBdn AYV46WGzhCpf5k86JNrcGLeJCqX9N+6GBwahLlqzE8VfbLYmOR3wFCbWeqSOx4U5 0rjW6vOAxudBbYJEI4u3Tp4kQ+qRisIbXevobR7vE0tLoTVQhD2vSFJ/uNZFl9c3 W9PSNUOKJbmx/eSHcfKCvbgaaxDyiI7j2eJ/qJABib+BJi3dayAH5Xth+i2MlmcN I50BBNASGL2GnxRm9bipgra1+JHogFtOEwbcyvD3jZ/QpX+VDxjw13aMUfYLTA59 U/efNpJAuJZNuwaNo0sBLNiS6Zmcb5ZGjmYZkgOuj412b5LddDg7HPK3a4AWHX/s pSPa7a1RKKxURD8DWMcuuc2k2aMqCCwV5lcVB0g2QNUkMlLN3005k2wQYW5keOxp bsKUsmB7hHbO3DdGe37d23mjerHdxD6Y//kIdKhqDibrasEy8LH3m6UhGljDMx4z U9/zrj2UPK2N5iwb7hUD =1F+V -----END PGP SIGNATURE----- ---

I concur. I use scp here exclusively with no issues. Although I am running SLES 10, but that should not make a difference. –El ab;2148532 Wrote:[color=blue] > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > rcp is pretty old… in fact, ancient, and insecure.

Andrey, some more details are in order then: Are both source and destination on the same subnet? If not, what’s the basic network setup (rcp through local routers vs. off-site, VPNs, Internet, whatever else is involved) Do pings go through between the involved nodes? Do they go through with large block sizes? Have you tried snooping with ethereal (“wireshark” nowadays) to see what the last part of the traffic is? Which “logs” have you checked? Does invoking rsh work? Any hangs in the output when transfering larger bits of stdout (from something like “find /”)?
