Public bug reported:
Binary package hint: openssh-server
Hi,
I am using Ubutu Hardy release 8.04 and openssh 4.7P1
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 8.04.1
Release: 8.04
Codename: hardy
r...@htaf1:~#
OpenSSH_4.7p1 Debian-8ubuntu1.2, OpenSSL 0.9.8g 19 Oct 2007
When I copy a 50+ MB file from one system to another Ubuntu
Using IPv4 address it took just less than 3 sec.
Same thing over IPv6 took more than an hour ( 1 Hr and 20 Min)
I copied the file using local IPv6 address. It ran fine. May be it is
using loop back, instead of real IPv6 address
When I initiate the same from a free BSD box to BSD It took less than 3 sec on
both Ipv4 and IPv6.
I can also copy from Ubuntu to a FreeBSD box faster both Ipv4 and IPv6 addreses.
I just can't copy the same from a Ubutu to Ubutu or other machines to
Ubuntu over IPv6 address.
It is very critical for our product :-(
I even tried getting the latest OpenSSH package from openssh.org and compiled
that module and ran that sshd.
Still no use. Same old behaviour.
It starts negotiating at 1.5 Mb/ sec and slowly drops to few KB / sec
and stalls the copy process during the time.
Any updates or known issues.
thanks in advance for your information on this issue.
