Amazon EC2 ssh login failure -

-

i trying login instance on ec2 , have far been unsuccessful. provide output of relevant commands , things i've tried. i've done homework , looked around, still cant explain why unable login.

the keypair generated online using amazons aws console , downloaded private file locally. chmod'ed 600.

$ ec2-describe-keypairs  keypair gsg-keypair bb:ac:f0:5f:5b:c8:24:47:16:a8:93:35:37:1c:b3:c3:84:68:80:e1  $ ec2-run-instances ami-8d18f5e4 -k gsg-keypair instance    i-2dcea041  ami-8d18f5e4            pending gsg-keypair 0   m1.small    2011-02-09t10:50:50+0000    us-east-1c  aki-a71cf9ce    ari-a51cf9cc        monitoring-disabled                 instance-store              xen   $ ec2-describe instances instance    i-2dcea041  ami-8d18f5e4    ec2-75-101-249-242.compute-1.amazonaws.com  domu-12-31-39-00-5d-d2.compute-1.internal   running gsg-keypair 0       m1.smal2011-02-09t10:50:50+0000 us-east-1c  aki-a71cf9ce    ari-a51cf9cc        monitoring-disabled 75.101.249.242  10.254.98.32            instance-store

i have run ec2-authorize default -p 22.

the output ssh is:

any appreciated here. i've tried million things , still cannot figure out going on.

thanks.

you might have permissions error:

failed add host list of known hosts (/home/meh/.ssh/known_hosts)

make sure user account has write access file /home/meh/.ssh/known_hosts

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
