Ssh – How to change topdir as a user in SSH

rpmssh

I have read several places NEVER to build RPM's as the root user. As such, I defined a new user and have tried building out RPM structures there, however, using the

rpmbuild --rebuild src.name.rpm

returns an error which states the topdir cannot be accessed:

Installing curl-7.20.1-1.src.rpm

error: cannot write to %sourcedir /usr/src/redhat/SOURCES

error: curl-7.20.1-1.src.rpm cannot be installed

does anybody know how to make this change? I have a correct /src/ directory set up under the new user.

from the Centos Wiki on how to setup a build enviroment (assuming you're enviroment is the same, change $HOME to a path or better variable as needed):

[userid@hostname ~]$ echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros

Beware: the second command will overwrite a previous .rpmmacros you might have, so you should check that you still do not have this file before running that command.

Basically what that is saying, is that you need to edit the users rpmmacros file to redirect the %_topdir macro to the new place on the file system that you want to be the topdir of your build environment.

SSH – How to Change Private Key Passphrase

To change the passphrase on your default key:

$ ssh-keygen -p

If you need to specify a key, pass the -f option:

$ ssh-keygen -p -f ~/.ssh/id_dsa

then provide your old and new passphrase (twice) at the prompts. (Use ~/.ssh/id_rsa if you have an RSA key.)

More details from man ssh-keygen:

[...]
SYNOPSIS
    ssh-keygen [-q] [-b bits] -t type [-N new_passphrase] [-C comment]
               [-f output_keyfile]
    ssh-keygen -p [-P old_passphrase] [-N new_passphrase] [-f keyfile]
[...]
     -f filename
             Specifies the filename of the key file.
[...]
     -N new_passphrase
             Provides the new passphrase.

     -P passphrase
             Provides the (old) passphrase.

     -p      Requests changing the passphrase of a private key file instead of
             creating a new private key.  The program will prompt for the file
             containing the private key, for the old passphrase, and twice for
             the new passphrase.

SSH – How to Perform Diff Over SSH

You can do it with Bash's process substitution:

 diff foo <(ssh myServer 'cat foo')

Or, if both are on remote servers:

diff <(ssh myServer1 'cat foo') <(ssh myServer2 'cat foo')
