View 1 Replies View RelatedA couple of weeks ago, I completed a system upgrade that was motivated because I have to deploy Windows 7. I have to deploy it because my Windows development environment is getting very long in the tooth, and I have to become current again for a project of mine that is underway. So, yesterday, I deployed Windows 7 Professional in VMware 7 hosted on Mandriva 2010. With my new upgrade, I have a very capable quad-core athlon system with an NVidia 240GT video card, and it runs Aero quite nicely in the virtual machine. I do have to say that Windows 7 looks nice and isn't too annoying to use, except - of course - when I need to dig into it to change some setting or another.
Now, on Windows, for many years I have used Zone Alarm firewall rather than the Windows firewall, because ZA monitors and controls outgoing connections. I have used this on both my Win2K development system (virtual machine) AND my Win XP laptop to keep microsoft applications (notably media player) from calling the mother ship when I didn't think they should. It has worked well. So one of my first actions was to download the newest copy of ZA free firewall and deploy it on Windows 7, after disabling the Windows firewall. Well guess what. ZA doesn't stop Windows from calling the mother ship. I have all settings on ZA set to "ask" before allowing anything to contact the net, but I've been playing with some multimedia things and the microsoft software has been talking on the internet as happy as you please, and ZA hasn't asked me a single time if it could do so.
Of course, when I ran a few tests with ping and tracert, ZA asked me. Also, I had to fiddle with ZA settings a bit to get the Windows 7 to successfully talk to my LAN. But when Windows 7 wants to talk to microsoft, it talks regardless of what ZA says. Well, when you get down to it, this is one reason I have Windows running in a VM...I WILL be in control, regardless of what microsoft wants. Does anyone know of a tool that I could use from Mandriva to prevent a VMware client from talking to a website? I'd like to be able to easily enable/disable it so that I can let Win 7 talk to microsoft when I need for it to do so, but no other time. I'm using bridged networking in VMware so all my virtual machines have their own IP addresses, but of course all of them (as well as my host Linux system) go through the same network adapter. It seems to me that iptables would have to work for this, but I'm not at all sure how to set it up to do it given the bridge.

I try to config my apache server to list all my files: c/c++, php, java files, like the txt file on my server,
e.g /var/www/mydomain/pub
i want to dump all my c/c++, php, java file under the pub directory and I can access it from my domain name,
if I dump txt file, I have no problem to view it, but when I dump c/c++ or php files under pub directory, then I can't view it like regular txt file,
Q: is there anyway I can configure my apache server to view all the c/C++, php, java file as like txt file?

View 1 Replies View RelatedI have a server with 8GIG of ram and a quad-core q9550 CPU and 500GIG of hard-disk space, and 100Mbps net connection.I have separated it into 3 parts of 2 Gigs of ram each, by virtualization, so there are 3 VPSes. The problem is that the one of the VPSes (created) with centos and WHM/cpanel would go down very often, as many as 60 times per day!I asked one of my friends to have a look at it, and he told me that Tomcat was the reason.Things got a little better (ask me what I changed about Tomcat?!) and after that the server would go down only about 20 to 30 times per day.I asked the friend again, and he told me that the CPanel integrated antivirus would cause the high load periodically.(Ask me again, what did I change?) And after that the server would go down only about 4 to 10 times per day.Now, as far as I can tell, there is nothing more that would/should cause the server to go down.
About 30 minutes ago, before writing this post, the hosted sites were unavailable again, for about 30 seconds.I checked the load through ssh and I saw that the load is 3, so I went to the main server and checked the VPS ram and noticed that only 10% of the cpu is used and only 307Mb of available RAM is used.
Everything shows that the server should be functioning OK, but it still seems to get unavailable far too often.
I used the top command and noticed that there is nothing using the cpu and the ram and all of them are 0.I used the mysqladmin proc command and again nothing noticeably weird seemed obvious at this time. I also checked the other VPSes and they were also in relatively low-resource-consumption states(I don't understand this part):Also sometimes I use the top command when the load goes high I see that all of the users, even the non visitors users site use cpu seems forexample a refreshing things or updating thing updates all of the accounts forexample mysql or so Please help me to figure out what other things might be causing these service/server high loads and unavailability.
I've got a Joomla website made for me. It is hosted with a hosting company. Here and there i change some of its content, but i want to practice it locally on my computer before i do bigger things on the web, so that if things get into a serious problem it is close at hand to fix it up. I've installed apache2 php5-mysql libapache2-mod-php5 mysql-server on my Ubuntu 10.04 desktop. also, I've installed Joomla up and running.
My question is: how do i transport/copy my website from the web into my computer?
I know that I need to transfer the database, where do i put it in my local file system, and what additional commands are required for that?

View 1 Replies View RelatedI have a debian machine with an apache2 webserver. I am able to start the machine from the internet (power plug board with webinterface) but I don't know how to shutdown the server automatically if nobody uses the website anymore. It is a homeserver which should only run if needed.
Unfortunately I don't know much about Linux, apache, php, cgi-scripts, cronjobs and other things that might be useful. But I googled a lot and have now an idea how it could work. It seems complicated to me and so I want to ask you guys what you think about it and if perhaps you could give me a hint.
The idea: A cronjob starts every ten minutes a php script that checks when the index.html of the welcome-page was opened the last time (fileatime()). Lets say it was opened last time at 3pm. Then the php script adds for example 60 minutes to that time (=4pm) and calculates how much time is left to 4pm. This time is saved in the variable $timeleft. Now the php script compares if $timeleft is less then 10 minutes (=600 seconds). If it is, the php script starts a cgi script that will shutdown the server. The cgi script will login as root (I think that can be done with the "expect"-command url and then enter the command "shutdown -h now"
Is all this realizable? Isn't there a better and/or easier way to do?
How can I view server signature on my website.
View 7 Replies View RelatedI have an Ubuntu 11.04 Server set up for my small office whose sole job is to run as a samba file server. The problem is that it randomly hangs. For example, I can connect the clients just fine, however if left idle it tends to take a few moments to work when you try to go back into the shared folder or drive. The client will behave like it is disconnected and is trying to search for the drive only to a few moments later, go right back to normal behavior.
If I ping this server while this is happening my requests will time out for a little while and then just start working. The same thing happens when I try to connect with Putty or through WebMin. One second its unreachable then the next its fine.I have already tried swapping out patch cables (which actually seemed to work for about 2 weeks) and I have patched it to an alternate port on the switch. The only thing I have not done at this time is to change the NIC.All the clients are running Win7 with the exception of two XP machines.Simply put, its like the machine just goes dormant for a while until you ping at it for a while to wake it back up.
Both server (web01), in DMZ, and client (app01), intranet, are Linux OEL5.5.
A few hints follows:
1- I ssh to web01, in DMZ, from a intranet machine on my desktop, export my DISPLAY, and try to bring up xclock; nothing happens.
2- traceroute from web01 to app01 fails.
3- NFS mount from web01, nfs server, to nfs client, app01, fails.
How should my network configuration on web01 or app01 be to make this NFS mount from web01 to app01 work?Each server has 4 NICs, I've only used eth0.
I run a CentOS 5.1 using VMServer on XP. From home I can successfully 'cvs login' to my CVS server. But starting 'cvs update', the connection times out.
Netstat shows the connection as established:
# netstat -an | grep 2401
tcp 0 0 192.168.1.35:58651 85.25.xx.xx:2401 ESTABLISHED
CVS server is domain managed with dnsalias service (dyndns.org)
Using the same computer at work (other ISP) I have no problems - cvs update works just fine.
Can I assume that it is not a port/firewall issue, since "cvs login" is successful? Any clues where to start diggin'?

View 14 Replies View RelatedSeismicmike here. My first post. I'll try to be as clear and concise as possible. For the sake of this post, I'm going to use 1.2.3.4 as a place holder for my public IP. On my web server, I would like to be able to access the /var/ftp directory through a web browser. I have successfully done so with Google Chrome, but I cannot access the directory in Firefox or IE. Both FF and IE ask me for authentication but then time out attempting to load the directory.
I suspect that there may be something up with switching to passive mode and/or that this issue may be more with my configuration of Firefox and not with the server (seeing as how Chrome works). Another possibility may be related to SSL. When I connect with FileZilla, I have to use the FTP over Explicit SSL/TLS option in order to connect. In any case I still would like to fix it. I would also like to avoid having to install FireFTP if at all possible.
Steps to reproduce (not that you can without my actual IP =J):
* Open Chrome
* Go to ftp://1.2.3.4
* Enter username
* Enter password

I recently setup a new Linux server running Fedora 10. For some reason all ping response times are rounded to the nearest 10ms. For example, running the simple command "ping yahoo.com" give the following sample results:
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=12 ttl=57 time=60.0 ms
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=13 ttl=56 time=50.0 ms
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=14 ttl=56 time=40.0 ms
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=15 ttl=56 time=50.0 ms
I could post a larger result set but its all the same... every response is rounded to a multiple of 10ms. This wouldn't be a big deal except that the server is running Nagios for monitoring so accurate stats are important. The Nagios check_ping and check_icmp commands are also returning rounded off results. How can I get ping to simply respond with the actual response times rather than a rounded off number?
I'm running Ubuntu 10.04 with apache, rails, mysql, etc. My rails site is running at www.example.com. I'm intending to use named-based virtual hosting and I have a virtual hosts file configured/enabled for www.example.com. My site is hosted on Amazon EC2.
The problem is that if I set up a new DNS record -- say test.example.com -- and browse to that, my site www.example.com is served up! That's without configuring any new virtual hosts. And the same is true if I go to my DNS records and define test2.example.com, etc. Without touching my server, these new URLs serve up my website. That's not what I want! I want to use name-based virtual hosting and host different sites for each subdomain.
[Code]...
UPDATE: now I understand a bit more... apparently my real problem is not what I thought it was. My real problem now appears to be that when I copy this virtual hosts file and edit it to add a new subdomain name, set up the corresponding site, etc., and enable the virtual host (a2ensite) and restart (graceful), apache immediately stops serving up any websites. Apparently apache crashes although I do not see any error messages. But all my sites go down and I have to revert and then restart apache.
I thought this was because my virtual host file (pasted above) had an error. So I thought I would start by getting that first file right. Apparently it is right. So now I need to understand why adding a second virtual host causes all sites to stop being served up.
