Remotely replaced sshd_config, CentOS 5.3/SSH 4.3p2-36el5_4.2 2009-11-12
Adam Hubscher (offbeatadam gmail com) (1 replies)
Hello Everyone,

Fighting a bit of a nasty morning... anyone seen this before?

We have a number of servers that have password authentication disabled
as well as shell access disabled for all users except those whom have
keys. These servers run cPanel and have been updated to the following specs:

SOLUTION ! [BUG?] sshd closes the connection after 2^16 bytes 2009-11-12
Matthieu Moy (Matthieu Moy grenoble-inp fr)
Hi,

Rather unbelievable, but upgrading the _kernel_ from 2.6.18-128.7.1 to
2.6.18-164.6.1 fixed the problem (we had good reasons not to upgrade,
but we worked around them).

Thanks,

Reverse port forwarding (-R) seems not working 2009-11-10
Vincenzo Romano (Vincenzo Romano notorand it) (3 replies)
Hi all.
I need to create a number of different reverse port forwarding (RPF)
with the -R option.
On the remote system I have set up a number of different dummy local
interfaces (dummy0=127.0.1.1 to dummy9=127.0.1.10).
A single RPF should look like this:

ssh -N -n -R 127.0.1.1:139:somelocalhost:139

[BUG?] sshd closes the connection after 2^16 bytes 2009-11-09
Matthieu Moy (Matthieu Moy grenoble-inp fr) (1 replies)
Hi,

I'm having trouble with the sshd on one particular machine. In short:

$ head -c 196481 /dev/zero | ssh machine-name 'LANG=C wc'
0 0 65536

(the 65536 here should have been a 196481 ...)

This happens whether I launch the command from the machine, or from
another remote machine. T

ssh tools and SSH_ASKPASS 2009-11-02
Ciprian Dorin, Craciun (ciprian craciun gmail com)
Hello all!

I've played this weekend with the SSH_ASKPASS feature of ssh-add
and ssh tools, and I must say that I like the idea, because it allows
me to input the passwords for either a key or authentication from a
(more) secure terminal. (For example if I don't trust my applications

Setting permissions of ssh access 2009-10-23
Scott Haneda (talklists newgeo com) (1 replies)
Hello, I've looked around and found a few different approaches to
this. Looking for a discussion of the pros, cons, and best practices.

I want to use rsync over an ssh connection to clone one machine to
another. This means one end will need root login.

Right now I have passwordless keys to all

alternate output for progressmeter 2009-10-24
Hans Harder (hans atbas org)
Hi,

I used scp in some background process for transferring large files
which took some hours.
For this I needed a less fancy output, preferable parseble by a script
, so I could regularly see how far the transfer was

The adaptions I made to progressmeter.c and .h are underneath my mail as a patch

Thank you all for your replies :)

This is the command i use: ssh -L 30300:localhost:8080 -R
1026:localhost:55555 -F ssh_config -N ipp (at) 10.55.40 (dot) 120 [email concealed]
And i close the ssh process by closing the windows console, or by
killing the ssh process from another application. Either way when i
look in processes

Hi,

Manipulating Forwards on an existing shell 2009-10-19
Quintin Beukes (quintin last za net) (1 replies)
Hey,

Is there any way at all to manipulate local forwards on an existing
shell? I basically have a script which I run to setup a bunch of port
forwards to create a pseudo-VPN. It's much stabler through SSH than it
is through our PPTP VPN. So it would be nice to create a zenity script
to setup insta

Adriana Rodean (adrya1984 gmail com) (1 replies)
Hi,

I'm not sure if this is a bug or not, maybe someone noticed it also...

I always do a remote port forwarding with openssh on 1026 port let's
say ( ssh -R 1026:localhost:55555 ). Most times the port is opened on
remote machine. But sometimes i notice that ssh can't do remote port
forwarding to t
