“easy_install” installs the latest version available of a python package. Sometime you need to use a specific version and you can install an earlier version of the package you need. For instance, if you need django 1.1.4, you’ll type:
#> easy_install "django==1.1.4"
Pretty simple eh?
Questions, doubts, comments are appreciated 
AWStats is a great software to analyse Apache logs for having statistics about your sites. Unfortunately it doesn’t offer a tool to import old logs into AWStats. For that I’ve created a small python script to do this. Here you go:
import commands
raw_data = commands.getoutput('ls -rt /var/log/apache2/wespot-access80.log.*.gz')
logs = raw_data.splitlines()
for log in logs:
commands.getoutput('zcat %s > /tmp/tmplog' % log)
commands.getoutput('/usr/lib/cgi-bin/awstats.pl -update -config=config.site.com -LogFile=/tmp/tmplog')
If you have problems, comment this post!
Hi! AWStats ships with a tool (logresolvemerge.pl) which does exactly the same thing. Also, I think the best way to use the script is not via a temporary file, but specifying something like this in the configuration:
LogFile=”…/awstats-7.0/tools/logresolvemerge.pl …/access.log* |”
The pipe symbol tells AWStats to read logs from the output of the command instead of from a file.
[This is with AWStats 7.0, I don't know about older versions]
Thanks Andrea for your suggestion! When I used AWStats, there wasn’t any tool to do that, so I created my own
Pretty simple.
#!/bin/sh for f in *; do g=`expr "xxx$f" : 'xxx\(.*\)' | tr '[A-Z]' '[a-z]'` mv -n "$f" "$g" done
and call it “rename.sh”
chmod u+x rename.sh
ls -1 | while read file ; do mv -nv “${file}” “$(echo “${file}” | tr ‘[A-Z]‘ ‘[a-z]‘)” ; done
Hi Luca, thanks for the trick.
I tried but it doen’t work.. I have this:
“namefile not overwritten”
It works only if I drop “-n” option from mv command (too risky!!)
If you have a PS with DreamHost and you need to use PostgreSQL as database, you’ll see that’s impossible to login with postgres user and so you won’t able to use PostgreSQL.
Dreamhost supports officially only MySQL, so they don’t provide any info about PostgreSQL.
Anyway the problem of using PostgreSQL in DH’s PS is permit the login to postgres user. Follow this two steps:
#>sudo su
postgres:x:32:32:PostgreSQL administrator,,,:/var/lib/postgresql:/bin/false
to:
postgres:x:32:32:PostgreSQL administrator,,,:/var/lib/postgresql:/bin/bash
Now you can become postgres user and you can use PostgreSQL.
Doubts? Comment!
PS: Are you looking for a serious, riable and fast hosting? So Dreamhost is for you! Use Dreamhost promo code “DIEGOR” or click on this link to get 50$ off right now!
Domanda forse stupida: cos’è che viene cambiato rispetto a prima? (sappi che non ho un hosting su Dreamhost, solo curiosità linuxiana 
)
La cosa che cambia è il comando da eseguire al login. Ho editato il post. Grazie per la precisazione.
In pratica abiliti la possibilità di login dell’utente postgres. Dovrebbe funzionare anche il comando (sempre da root): usermod -s /bin/bash postgres 
Telnet is an old utility used in local network to offer a bidirectional communication text-oriented using a terminal. Can be used also to make an http call to a remote server with the purpose of testing. Let’s see how:
#> telnet diegor.it 80
and you should have as output:
Trying 75.119.192.123... Connected to diegor.it. Escape character is '^]'.
GET / HTTP/1.1 host: diegor.it <line feed>
where “/” is the remote path. In this case we want the root. The output looks like this below:
HTTP/1.1 200 OK Date: Mon, 13 Jun 2011 09:06:43 GMT Server: Apache Cache-Control: no-cache, must-revalidate, max-age=0 Pragma: no-cache Expires: Wed, 11 Jan 1984 05:00:00 GMT Last-Modified: Sun, 12 Jun 2011 13:29:48 GMT Vary: Accept-Encoding Content-Length: 85589 Content-Type: text/html;charset=UTF-8 ...
Pretty simple! Any questions or comments are welcome.
Careful there, maybe that MaxOS X telnet is very smart, but usually the command is in the form “telnet hostname port”. So, ‘telnet http://www.diegor.it 80′ is a better way to do this, the protocol is specified by the port number.
I can’t get what are you saying. Where’s the “error”?
Ok, now i get it. The problem is that this fucking wordpress put “http://” as prefix in www addresses
Hahahaha OK, that’s a sound explaination. 
Besides, WP has put an http:// also in front of my comment’s telnet string ))
Yes, I saw that! fucking WP
A public web server could be reached by many http requests with no user agent. Apache can avoid this kind of requests. The configuration is very straightforward:
<Directory /path/to/a/directory> SetEnvIfNoCase User-Agent "^-?$" noUserAgent Order Allow,Deny Allow from All Deny from env=noUserAgent </Directory>
In this example Apache ignores all requests without user agent that are directed to /path/to/a/directory
Any comments are appreciate.
I used to manage a server based on linux and once I had this strange message:
#> ip_conntrack: table full, dropping packet
One of the effects of this message is that you aren’t able to make and receive new connections.
To solve that is enough increase ip_conntrack_max value. As first step check the current value typing:
#> cat /proc/sys/net/ipv4/ip_conntrack_max 65536
Now, increase this value typing:
#> echo 131072 > /proc/sys/net/ipv4/ip_conntrack_max
Generally the right value of ip_conntrack_max is set to the total MB of RAM multiplied by 16. If you have 8GB RAM (8192 MB), the value should be 131072.
Andrea Corbellini are discussing.
