Message-ID: <20011214233200.A84807@ldc.ro> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG I am using ssh over a slow modem (28k, connects only at 14k because of a very noisy line). My problem is that the new ssh seems to handle output from programs differently from older versions. To be more precise, issuing "ipfw list" on a 10-rule firewall (mostly diverts to pipes, I also use ipfilter) takes noticeably longer than "ipfw list | cat". Also, a tcpdump on my tun0 interface shows three packets for "sleep 5;ipfw list|cat", and "sleep 5;ipfw list" gives over 50 packets (both cases counting ACKS). Is there a way to speed things up? The versions of ssh I am using are: local(client): OpenSSH_2.9 FreeBSD localisations 20010713 remote(server): OpenSSH_2.9 FreeBSD localisations 20010713 The server is running -STABLE cvsupped some 25 days ago, the client is cvsupped this week. Arguments to ssh were "-v -C -l username". Server only supports protocol version 2. Thanks!
