Felipe Alvarez's questions

i'd like to allow user 'devel' to login to any other server using public keys as user 'devel'. This user is not a human, but a scripting-only account. How can I accomplish this? Is Puppet the right way? How does each source server receive the necessary key material? I am very aware of the how private and public keys are used for SSH authentication and the degree of confidentiality that goes with private keys.

Assume there are 100 servers, and private & public keys need to be changed every 90 days.

I have a file formsweb.cfg which might look a little like this

# These match variables (e.g. %form%) in the baseHTML file. Their values
# may be overridden by specifying them in the URL query string
# (e.g. "http://myhost.example.com/forms/frmservlet?form=myform&width=700")
# or by overriding them in a specific, named configuration (see below)
[default]
# Default Oracle Forms values:
#baseHTML=base.htm
#baseHTMLjpi=basejpi.htm
width=1366
height=734

[sepwin]
separateFrame=True
lookandfeel=Generic

[debug]
serverURL=/forms/lservlet/debug

This file is missing the key-value clientDPI=96 which should be located in the [default] section of this file.

On 100+ sites, some of the files might have clientDPI set, others might not.

I want to add the value to files which do not currently have it.

This is the sed script that I wrote. Is there a "better" way to do it?

sed -n '/\[default\]/,/^\[/ {
  /^clientDPI/q1
}' formsweb.cfg &&

sed '/\[default\]/,/^\[/ {
 /^\[default\]/ {
   a\
clientDPI=96
 }
}' -i.bak.${RANDOM} formsweb.cfg

It checks if clientDPI exists between [default] and the next [ character. If it does it quits with 1, otherwise, it goes to the next sed line, which does the insert.

GNU sed version 4.1.5

Trying to run tar with --files-from. I have a file files.txt that contains

/dir1/files*.txt

However it complains that /dir1/files*.txt does not exist, but ls proves that it does.

I tried to also add --wildcards however same result.

How do I successfully archive wildcards while using --files-from without specifying files on the command line?

Update

Thanks for all the replies so far. I'd like to make clear that the number after user (e.g. user1) in my example is not significant. The user can be any alphanumeric name.

I want to make sure that if a directory is specified, we append "/faces/main.jsf" to the end of it.

For example

We want to URL to look like:

example.com/user1/faces/main.jsf

The system could append things like (which we must allow)

 http://example.com/user1/faces/main.jsf;jsessionid=Z_DV-bY6MuQGlIvflPwgdKDk60cNzOkWXbC5G18ILrjR0jKoGWnd!-617980607

If a request looks like either of these:

example.com/user1
example.com/user1/

I'd like "/faces/main.jsf" to be appended to it. What's wrong with my rewrite rules?

<VirtualHost *:80>
    ServerName          example.com
    ProxyPass           /       http://1.example.com:8888/
    ProxyPassReverse    /       http://1.example.com:8888/
    RewriteEngine       On
    # RewriteLog          /tmp/rewrite.log

    RewriteCond %{HTTP_HOST} !^example.com$
    RewriteRule !^/(.) http://example.com/$1 [L,R]

    RewriteCond %{REQUEST_URI}  !^/(.+/)faces/main.jsf.*
    RewriteRule !^(.+)/faces/main.jsf.*$  $1/faces/main.jsf [L,R]
</VirtualHost>

My SnapGear (now McAfee) SG560 (firmware Version 4.0.10) has a "remote system log" feature, which can send syslog-type data to a host in my network. It's working, but writing to /var/log/messages. I'd like it to store this information in a different file. I think that knowing the facility, I can change syslog.conf, however Googling hasn't turned anything up.

What is the "facility" for system log?

Two servers. example.net, and example.com

On http://example.net, My httpd.conf contains

# example.net
RewriteEngine On
RewriteRule  ^/felipetest2 http://example.com/webpage [P]

I am getting a 302 Moved, which is pointing to http://example.net/webpage, but should be http://example.com/webpage

What's going on?

I have control over both .net and .com servers in these examples.

I know I can do the same with ProxyPass and ProxyPassReverse, but I'm trying to get my head around this one.

Edit: Main Question: How do I show a maintenance page, without changing URL in the browser? On same domain, or across different domains?

I have a 500GB external drive. It had two partitions, each around 250GB. I removed the first partition. I'd like to move the 2nd to the left, so it consumes 100% of the drive. How can this be accomplished without any GUI tools (CLI only)?
