  • Why is crontab giving "No such file or directory" error when the file DOES exist?

    - by fettereddingoskidney
    I am getting the following three lines in an error message in /var/mail/username after the following job runs in crontab... 15 * * * * /Applications/MAMP/htdocs/iconimageryidx/includes/insertPropertyRESI.php Errors: /applications/mamp/htdocs/iconimageryidx/includes/insertpropertyRESI.php: line 1: ?php: No such file or directory /applications/mamp/htdocs/iconimageryidx/includes/insertpropertyRESI.php: line 3: syntax error near unexpected token `'initialize.php'' /applications/mamp/htdocs/iconimageryidx/includes/insertpropertyRESI.php: line 3: `require_once('initialize.php'); The PHP script I am trying to execute DOES in fact exist, and I have made absolutely sure the spelling is correct several times. I ran a crontab on another script before and it worked just fine...any ideas?? The 2nd & 3rd Errors are from line 3 in the following script (the one I am trying to run with the crontab): <?php require_once('initialize.php'); require_once('insertPropertyTypes.php'); $sDate; if(isset($_GET['startDate'])) { $sDate = $_GET['startDate']; } else { $sDate = ''; } $insertResi = new InsertPropertyTypes('Listing', $sDate, 'RESI'); ?> When I run my script insertPropertyRESI.php in the browser, it runs just fine???? Also, initialize.php and insertPropertyTypes.php are in the same directory as insertPropertyRESI.php I am using MAMP with PHP 5.3.5 thakns for the help :?

  • How to convert Markdown files to Dokuwiki, on a PC

    - by Clare Macrae
    I'm looking for a tool or script to convert Markdown files to Dokuwiki format, that will run on a PC. This is so that I can use MarkdownPad on a PC to create initial drafts of documents, and then convert them to Dokuwiki format, to upload to a Dokuwiki installation that I have no control over. (This means that the Markdown plugin is no use to me.) I could spend time writing a Python script to do the conversion myself, but I'd like to avoid spending time on this, if such a thing exists already. The Markdown tags I'd like to have supported/converted are: Heading levels 1 - 5 Bold, italic, underline, fixed width font Numbered and unnumbered lists Hyperlinks Horizontal rules Does such a tool exist, or is there a good starting point available? Things I've found and considered I initially thought that txt2tags would be helpful, but although it can write both markdown and Dokuwiki, it is very tied to its own specific input format I've also seen Markdown2Dokuwiki, and although I'd certainly be willing to use a sed script, even on a PC, this only supports a tiny, tiny part of Markdown's syntax. python-markdown2 also sounded promising, but it only writes out HTML. pandoc - but it doesn't support Dokuwiki output MultiMarkdown - does not appear to support Dokuwiki output

  • Nginx rewrite for link shortener + Wordpress pretty URLs

    - by detusueno
    Okay so I installed Nginx/PHP/MySQL/Wordpress via a online walk through, and it had me enter these rewrites to enable Wordpress pretty URLs: if (-f $request_filename) { break; } if (-d $request_filename) { break; } rewrite ^(.+)$ /index.php?q=$1 last; error_page 404 = //index.php?q=$uri; This is then included in the vhost for my domain. What I'm trying to do now is add some redirection/link shortner rewrites that will play nice with the setup I have in mind. I'd like to redirect "x.com/y" to "x.com/script.php?id=y" for all external links that I post. The Wordpress link setup right now has almost all internal links begin with "news" (x.com/news/post-blah, x.com/news/category/1, etc) BUT I also have a few root links that point to some internal content (x.com/news, x.com/start). I'm guessing that's going to cause some conflicts. What's the best approach to do this? I've never worked with Nginx (or any rewrite rules) but maybe I can distinguish between "x.com/news" and "x.com/news/" to allow it to play nice? I had a friend setup a working version of this in Apache and it'd be nice if I could get this up on Nginx again.

  • 2010 cgi script failure

    - by Barry F
    Hi. I hope you can help, I'm just a beginner! I have listed a few extra details which may not be relevant. I upload cgi scripts onto local/personal directory on a Apache/2.2.10 server, using FTP95Pro in ASCII. The scripts execute correctly using perl on my web-server in a terminal session. Thus my code has no fatal syntax errors. Webpages 'action' each cgi script at /cgi-bin/. There are symbolic links which link system directory files to my local directory files. FollowSymLinks is enabled (unsure how). Permissions are correct (755). This set-up hasnt changed, apparently. The scripts have excuted perfectly for years, up to 2010. But now, in 2010, I have replaced working scripts with new script/files, now with exactly the same text, filename and permissions. Only the date (last modified) has changed. But now I receive a 500 Internal Server Error, and cannot determine why. My server administator assumes I have code errors. But code is unchanged since last year, and it runs fine (albeit no arguments) on web-server console using perl myscript.cgi Is there anything you can think of which may have changed ? I'm suspicious of the new decade. I think the server swapped from Linux to Windows OS last year, but my server administrator got it all working OK. Is there something unusual he may have missed, related to 2010 ? Thank you in advance

  • HTTPS/HTTP redirects via .htaccess

    - by Winston
    I have a somehow complicated problem I am trying to solve. I've used the following .htaccess directive to enable some sort of Pretty URLs, and that worked fine. For example, http://myurl.com/shop would be redirected to http://myurl.com/index.php/shop, and that was well working (note that stuff such as myurl.com/css/mycss.css) does not get redirected: RewriteEngine on RewriteCond ${REQUEST_URI} !^(index\.php$) RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^/?(.*)$ index.php/$1 [L] But now, as I have introduced SSL to my webpage, I want the following behaviour: I basically want the above behaviour for all pages except admin.php and login.php. Requests to those two pages should be redirected to the HTTPS part, whereas all other requests should be processed as specified above. I have come up with the following .htaccess, but it does not work. h*tps://myurl.com/shop does not get redirected to h*tp://myurl.com/index.php/shop, and h*tp://myurl.com/admin.php does not get redirected to h*tps://myurl.com/admin.php. RewriteEngine on RewriteCond %{HTTPS} on RewriteCond %{REQUEST_URI} !^(admin\.php$|login\.php$) RewriteRule ^(.*)$ http://%{HTTP_HOST}/${REQUEST_URI} [R=301,L] RewriteCond %{HTTPS} off RewriteCond %{REQUEST_URI} ^(admin\.php$|login\.php$) RewriteRule ^(.*)$ https://myurl.com/%{REQUEST_URI} [R=301,L] RewriteCond %{REQUEST_URI} !^(index\.php$) RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^/?(.*)$ index.php/$1 [L] I know it has something to do with rules overwriting each other, but I am not sure since my knowledge of Apache is quite limited. How could I fix this apparently not that difficult problem, and how could I make my .htaccess more compact and elegant? Help is very much appreciated, thank you!

  • iptables to block VPN-traffic if not through tun0

    - by dacrow
    I have a dedicated Webserver running Debian 6 and some Apache, Tomcat, Asterisk and Mail-stuff. Now we needed to add VPN support for a special program. We installed OpenVPN and registered with a VPN provider. The connection works well and we have a virtual tun0 interface for tunneling. To archive the goal for only tunneling a single program through VPN, we start the program with sudo -u username -g groupname command and added a iptables rule to mark all traffic coming from groupname iptables -t mangle -A OUTPUT -m owner --gid-owner groupname -j MARK --set-mark 42 Afterwards we tell iptables to to some SNAT and tell ip route to use special routing table for marked traffic packets. Problem: if the VPN failes, there is a chance that the special to-be-tunneled program communicates over the normal eth0 interface. Desired solution: All marked traffic should not be allowed to go directly through eth0, it has to go through tun0 first. I tried the following commands which didn't work: iptables -A OUTPUT -m owner --gid-owner groupname ! -o tun0 -j REJECT iptables -A OUTPUT -m owner --gid-owner groupname -o eth0 -j REJECT It might be the problem, that the above iptable-rules didn't work due to the fact, that the packets are first marked, then put into tun0 and then transmitted by eth0 while they are still marked.. I don't know how to de-mark them after in tun0 or to tell iptables, that all marked packet may pass eth0, if they where in tun0 before or if they going to the gateway of my VPN provider. Does someone has any idea to a solution? Some config infos: iptables -nL -v --line-numbers -t mangle Chain OUTPUT (policy ACCEPT 11M packets, 9798M bytes) num pkts bytes target prot opt in out source destination 1 591K 50M MARK all -- * * 0.0.0.0/0 0.0.0.0/0 owner GID match 1005 MARK set 0x2a 2 82812 6938K CONNMARK all -- * * 0.0.0.0/0 0.0.0.0/0 owner GID match 1005 CONNMARK save iptables -nL -v --line-numbers -t nat Chain POSTROUTING (policy ACCEPT 393 packets, 23908 bytes) num pkts bytes target prot opt in out source destination 1 15 1052 SNAT all -- * tun0 0.0.0.0/0 0.0.0.0/0 mark match 0x2a to:VPN_IP ip rule add from all fwmark 42 lookup 42 ip route show table 42 default via VPN_IP dev tun0

  • nginx- Rewrite URL with Trailing Slash

    - by Bryan
    I have a specialized set of rewrite rules to accommodate a mutli site cms setup. I am trying to have nginx force a trailing slash on the request URL. I would like it to redirect requests for domain.com/some-random-article to domain.com/some-random-article/ I know there are semantic considerations with this, but I would like to do it for SEO purposes. Here is my current server config. server { listen 80; server_name domain.com mirror.domain.com; root /rails_apps/master/public; passenger_enabled on; # Redirect from www to non-www if ($host = 'domain.com' ) { rewrite ^/(.*)$ http://www.domain.com/$1 permanent; } location /assets/ { expires 1y; rewrite ^/assets/(.*)$ /assets/$http_host/$1 break; } # / -> index.html if (-f $document_root/cache/$host$uri/index.html) { rewrite (.*) /cache/$host$1/index.html break; } # /about -> /about.html if (-f $document_root/cache/$host$uri.html) { rewrite (.*) /cache/$host$1.html break; } # other files if (-f $document_root/cache/$host$uri) { rewrite (.*) /cache/$host$1 break; } } How would I modify this to add the trailing slash? I would assume there has to be a check for the slash so that you don't end up with domain.com/some-random-article//

  • iptables configuration under ubuntu

    - by aioobe
    I'm following a tutorial on setting up a dns-tunnel. I've run into the following instruction: Now you need to enable forwarding on this server. I use iptables to implement masquerading. There are many HOWTOs about this (a simple one, for example). On Debian, the configuration file for iptables is in /var/lib/iptables/active. The relevant bit is: *nat :PREROUTING ACCEPT [6:1596] :POSTROUTING ACCEPT [1:76] :OUTPUT ACCEPT [1:76] -A POSTROUTING -s 10.0.0.0/8 -j MASQUERADE COMMIT Restart iptables: /etc/init.d/iptables restart The problem is that I don't have any /var/lib/iptables/active. (I'm on ubuntu.) How can I accomplish this? I suspect that I should just interact with the iptables command somehow but I have no clue what to write. Best would probably be if I could put the commands in a script somehow I suppose. (A side-note. If I execute a few iptables-commands it wont be there for ever, right? The rules will be discarded on reboot?)

  • Mod_rewrite to eliminate query strings

    - by Greg Frommer
    Hi everyone, I have been working on this for a while but I'm not finding exactly what I am looking for. I am writing a webapp to let my users create and publish pieces of HTML content in a domain and URL folder structure of their choosing. All of the content and requested URL structures are stored in a database. I have all of the code in my index.php (in the root folder) to access the database content, and based on the server name (and hopefully folder structure) will pick out the proper content from the DB and display it to the end-users browser. So my situation looks like this: www.test.com/index.php?id=123234345 ... will display the proper page, but I want my users to be able to define a unique "page name" instead of using the numeric index (also I want to hide the /index.php part) so what I would like the end-user to see is: www.test.com/arbitrary-unique-keyword/keyword2/keyword3 which will invoke the index.php page in the root folder. Then I will use the PHP $_SERVER['PATH_INFO'] variable to match the requested folder structure up with the proper content in my database and display that. All the material I have found so far expects me to hard code parts of the folder structure into the rules.... but I think I want something simpler (perhaps). So the question in a nutshell: How do I use mod_rewrite to allow all "non-existent" folder paths be passed through to a main index.php residing in the root folder? (For all paths that DO exist, like for calls to images... I want those to succeed and not be directed to the index.php obviously) Thanks everyone, please let me know if I can clear anything up.

  • How CPU communicates with HW

    - by b-gen-jack-o-neill
    Good day. I am new here, but I could not find answer to my question using google, so I help I do not violate any rules. So, basically, all I want to ask is, how CPU comminucates with other HW, such as printers, Graphic card, sound card, LAN card etc. I know, that for basic system I/O, you can use BIOS interrupts. INT 10h I believe is for display output. But, what I would like to know is, what actually happens when you execute instruction int 10h. From desription of int instruction, it should jump to routine, which is stored on adress pointed by adress stored in iterrupt table. But how does this routine get into the RAM? Does BIOS save that routines to the RAM? And what actually that routine does? I mean, CPU can only acess RAM, right? So how can now acess some other HW? Is there some special instrucion for it? Or is CPU somehow connected to BIOS, and than BIOS actually does the work? And the last thing, does even OS like Windows or GNU/Linux use BIOS interrupts, or can OS acess HW directly? Thanks.

  • Use a preferred username but authenticate against Kerberos principal

    - by Jason R. Coombs
    What I desire to do should be pretty simple. I have an Ubuntu 10.04 box. It's currently configured to authenticate users against a kerberos realm (EXAMPLE.ORG). There is only one realm in the krb5.conf file and it is the default realm. [libdefaults] default_realm = EXAMPLE.ORG PAM is configured to use the pam_krb5 module, so if a user account is created on the local machine, and that username matches the [email protected] credential, that user may log in by supplying his kerberos password. What I would like to do instead is create a local user account with a different username, but have it always authenticate against the canonical name in the kerberos server. For example, the kerberos principal is [email protected]. I would like to create the local account preferred.name and somehow configure kerberos that when someone attempts to log in as preferred.name, it uses the principal [email protected]. I have tried using the auth_to_local_names in krb5.conf, but this doesn't seem to do the trick. [realms] EXAMPLE.ORG = { auth_to_local_names = { full.name = preferred.name } I have tried adding [email protected] to ~preferred.name/.k5login. In all cases, when I attempt to log in as preferred.name@host and enter the password for full.name, I get Access denied. I even tried using auth_to_local in krb5.conf, but I couldn't get the syntax right. Is it possible to have a (distinct) local username that for all purposes behaves exactly like a matching username does? If so, how is this done?

  • Generating alerts from ossec ( server- agent ) model

    - by batman
    I'm very new to OSSEC. I use a server-agent model. I wish to generate alert for the following actions ( in agent side ): 1) Sample Alert for delation of logs I added the rules for these in agent's ossec.conf using <localfile> tags. Like this : <localfile> <log_format>syslog</log_format> <location>/var/log/syslog</location> </localfile> In my server's ossec.conf. I added the following : <global> <email_notification>yes</email_notification> <email_to>xxxx@xxxxxx</email_to> <smtp_server>smtp.gmail.com</smtp_server> <email_from>xxxx@xxx</email_from> </global> And I restarted my server. Now I tried to delete the agents syslog file using rm syslog. But no alerts has been triggered. Where I'm making the mistake?

  • How to enable hotlink protection without hardcoding my domain in the Apache config file?

    - by Jeff
    Been surfing around for a solution for a couple days now. How do I enable Apache hotlink protection without hardcoding my domain in the config file so I can port the code to my other domains without having to update the config file every time? This is what I have so far: RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http://www\.example\.com [NC] RewriteRule \.(gif|ico|jpe|jpeg|jpg|png)$ - [NC,F,L] ... And this is what Apache suggests: SetEnvIf Referer example\.com localreferer <FilesMatch \.(jpg|png|gif)$> Order deny,allow Deny from all Allow from env=localreferer </FilesMatch> ... both of which hardcode the domain in their rules. The closest I came to finding any info that covers this is right here on ServerFault, but the conclusion was that it cannot be done. Based on my research, that appears to be true, but I didn't find any questions or commentary dedicated soley to this question. If anyone's curious, here is the link to the Apache 2 docs that cover this topic. Note that Apache variables (e.g. %{HTTP_REFERER}) can only be used in the RewriteCond text-string and the RewriteRule substitution arguments.

  • TC hashing filters - single rule deletion

    - by exa
    For traffic shaping I'm currently using a setup that looks exactly like the setup from LARTC, on this page: http://lartc.org/howto/lartc.adv-filter.hashing.html I have a simple problem with that - everytime I want to modify something in the hash table (like assign a IP to different flowid), I need to delete the whole filter table and add it again filter by filter. (I actually don't do it by hand, I have a nice program that does it for me... but still...) There is a problem - I got roughly 10k filters allocated this way and deleting and refilling the whole filtertable can get pretty lengthy, which is not exactly good for traffic shaping. My program could easily manage to delete only the rules that need to be deleted (thus reducing the whole problem to several commands and miliseconds), but I simply don't know the command that deletes only the one hashing rule. My tc filter show: filter parent 1: protocol ip pref 1 u32 filter parent 1: protocol ip pref 1 u32 fh 2: ht divisor 256 filter parent 1: protocol ip pref 1 u32 fh 2:a:800 order 2048 key ht 2 bkt a flowid 1:101 match 0a0a0a0a/ffffffff at 16 filter parent 1: protocol ip pref 1 u32 fh 2:c:800 order 2048 key ht 2 bkt c flowid 1:102 match 0a0a0a0c/ffffffff at 16 filter parent 1: protocol ip pref 1 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0 link 2: match 00000000/00000000 at 16 hash mask 000000ff at 16 The wish: 'tc filter del ...' command that removes only one specific filter (for example the 0a0a0a0a IP match (IP address 10.10.10.10)). Removal of some small subgroup would also be good - for example I could still recreate a bucket (bkt a) pretty fast. My attempts: I tried to number all the filters using prio, but with no help -- they just create something unusuable (but deletable) below, but the bucketed filters remain there after that gets deleted. Any ideas? edit - I'm adding a simplified tl;dr description of the problem: I created hash filter on some interfce just like in this http://lartc.org/howto/lartc.adv-filter.hashing.html I want to find a command that deletes one rule (e.g. 1.2.1.123) from the table, leaving the rest untouched and working.

  • Using my own Postfix, filtering spam and getting all the mail into my ISP's inbox

    - by djechelon
    Hello, I currently own a domain bought via GoDaddy.com, which provides me a basic email setup for the most common needs. I configured it to forward all mail to [email protected] to [email protected]. I also own a virtual server with a running Postfix that I use for a specific website (all mail to somedomain.com gets forwarded via LMTP to a program written by me). Since I'm recently experiencing some harassing by spammers, since GoDaddy doesn't seem to filter spam, and since my Windows Phone's Pocket Outlook cannot filter spam, I would like to use SpamAssassin to filter inbound spam by changing my domain's MX records to my server My ideal setup is the following: All mail delivered to somedomain.com gets redirected via LMTP as usual via virtual transport without any spam check All mail to [email protected] gets redirected to [email protected] after a severe spam check I don't care about [email protected] since I use just one address for now I would like to train SpamAssassin with customized spam rules, possibly based on the presence of certain keywords (links to certain unsubscribe pages I found recurring) I currently configured Postfix with transport somedomain.com lmtp:[127.0.0.1]:8025 .somedomain.com error: Cannot accept mail for this domain relay somedomain.com OK (I guess I should add mydomain.com OK too) virtual @mydomain.com [email protected] (looks like a catch-all rule, it's OK as requirement 3) I installed SpamAssassin, I can do rcspamd start and set it to boot with the server, but I don't know if there is anything else to do for use in Postfix, and how to apply requirement 1 (only mail to mydomain.com gets filtered) I also tried to send an email via Telnet to make sure my settings are ready for MX change. I received the message into my account but I found that it gone through secureserver.net, like Postfix didn't rewrite the destination but simply relayed the message. Thank you in advance. I'm no expert in SpamAssassin, and I have little experience in Postfix (enough to avoid making my server an open relay)

  • Where to put the SPF TXT record?

    - by YellowSquirrel
    I've set up Google apps for my domain: I've registered the domain with Google by adding the CNAME Google asked and I've apparently succesfully setup the MX Google mail servers. So far I haven't yet a dedicated server: I'm just having a domain at a registrar. Now I want to activate SPF and I'm confused. In the following short webpage: http://www.google.com/support/a/bin/answer.py?answer=178723 it is written that I must add a TXT record containing: v=spf1 include:_spf.google.com ~all Where should I enter this? Should this go in the zone (?) file, like I did for the CNAME and the MX records? So far I have something like this: @ 10800 IN A 217.42.42.42 @ 10800 IN MX 5 ASPMX3.GOOGLEMAIL.COM. @ 10800 IN MX 5 ASPMX2.GOOGLEMAIL.COM. @ 10800 IN MX 3 ALT2.ASPMX.L.GOOGLE.COM. @ 10800 IN MX 3 ALT1.ASPMX.L.GOOGLE.COM. @ 10800 IN MX 1 ASPMX.L.GOOGLE.COM. google8a70835987f31e34 10800 IN CNAME google.com. Does adding the SPF TXT record mean I should literally have something like that: @ 10800 IN A 217.42.42.42 @ 10800 IN MX 5 ASPMX3.GOOGLEMAIL.COM. @ 10800 IN MX 5 ASPMX2.GOOGLEMAIL.COM. @ 3600 IN TXT "v=spf1 include:_spf.google.com ~all" @ 10800 IN MX 3 ALT2.ASPMX.L.GOOGLE.COM. @ 10800 IN MX 3 ALT1.ASPMX.L.GOOGLE.COM. @ 10800 IN MX 1 ASPMX.L.GOOGLE.COM. google8a70835987f31e34 10800 IN CNAME google.com. I made that one up and included right in the middle to show how confused I am. What I'd like to know is the exact syntax and where/how I should put this TXT record.

  • Is it possible for the Subversion Apache module to serve html files with an html content-type without using the svn:mime-type property?

    - by Martin Pain
    I am aware that if you set the svn:mime-type Subversion property on a .html file to text/html then when viewing the file in a browser through the Subversion module in Apache httpd it will be served with a Content-Type: text/html header, enabling the browser to render it as HTML rather than plain text. However, I am looking for a way to do this without using the svn:mime-type property. I'm aware that you can configure your svn client to automatically add the property - this is not what I want, as I do not want to ensure all users have these settings. I'm also aware that I could create a pre-commit hook that rejects the commit if the properties are not set, in order to force users to set the property - I might fall back to that, but I'm looking for something less intrusive. I'm also aware that I could use a post-commit hook to add the properties automatically on the server-side. I'd rather not do that (as users then have to update immediately after their commit, and it's not trivial to write) - I'm looking for a better alternative. Perhaps something with rewrite rules in the Apache server?

  • What does "incoming" and "outgoing" traffic mean?

    - by mgibsonbr
    I've seen many resources explaining how to set up a server's firewall to allow incoming and outgoing traffic on HTTP standard ports (80 and 443), but I can't figure out why I would need either of them. Do I need to unblock both for a "regular" web site to work? For file uploads to work? Are there situations where it would be advisable to unblock one and leave the other blocked? Sorry if that's a basic question, but I couldn't find it explained anywhere (also I'm not a native english speaker). I know in a "regular" web site the client is always the one who initiates a request, so I'm assuming a web server must accept incoming traffic on those ports, and my common sense tells me the server is allowed to send a response without unblocking anything else (otherwise it wouldn't make sense to have two types of rules). Is that correct? But what is an outgoing web (service) traffic, and what would be its use? AFAIK if the server wanted to initiate a connection with another machine, the specific port that matters is the one in the other end (i.e. the destination port would be 80), on its end any free port could be used (the source port would be random). I can open HTTP requests from my server (using wget for instance) without unblocking anything. So I'm assuming my concepts of "incoming" and "outgoing" are wrong somehow.

  • Proper web server setup

    - by DMin
    I just got myself a slicehost basic slice to play around with so I can learn how to setup web-servers. I have Ubuntu 10.04.2 installed on the server. I was able to successfully get the server up and running from scratch, these were the things I did - following this tutorial. I know this is probably just a starters tutorial, so, I was wondering if you guys can tell me what you like to do while setting up production servers. These are the steps that were followed : Update and Upgrade Ubuntu sudo apt-get install apache2 php5-mysql libapache2-mod-php5 mysql-server Backup a copy of and edit apache2.conf Set : 'ServerTokens Full' to 'ServerTokens Prod''ServerSignature On' to 'ServerSignature Off' Backup php.ini and then Change “expose_php = On” to “expose_php = Off” Restart Apache Install Shorewall firewall Configure Shorewall to only accept HTTP and SSH connections(in the rules file) Enable shorewall on startup Add the website to the server : sudo usermod -g www-data root sudo chown -R www-data:www-data /var/www sudo chmod -R 775 /var/www I want make this CommunityWiki but can't seem to find the option to do it. Please feel free to add any feedback on the processes and things I am doing right/wrong. Much appriciated, thanks! :)

  • DD-WRT Acces Point as a Router

    - by Dzh
    Following suggestion to this question asked on Network Engineering, I am asking the question here. this is an extension to my previous question (I think it was deleted), where I was claiming that DDWRT was disabling it's DHCP server once connected to the network. I was wrong, as it now seems that it is bridging itself with another parallel connected wireless router. I have two Draytek 2820 and one Netgear WG602v3 with latest DDWRT. Lets call one wired-Draytek and it has wireless disabled. The other one, let's call it wireless-Draytek, is connected to wired-Draytek and has wireless with MAC filtering enabled. Once I connect Netgear to the wired-Draytek, the client that connects to Netgear, will be assigned with IP address from the wireless-Draytek. If the MAC address is not on the wireles-Draytek, the client is unable to obtain IP address and has no connectivity at all, even with manually assigned static IP configuration. To illustrate further, this is how network is set up: wired-Draytek ---------- wireless-Draytek \_________ Netgear What I wish to have, is that Netgear issues IP addresses from it's own IP pool and ignores the MAC filtering rules from wireless-Draytek. This is kind of puzzling how this they are bridging (if they are) themselves automatically. Thanks. UPDATE: It's not a home network. I gave you a bit simplified set-up. If there is a better site on Stack Exchange to ask this, please let me know. The Drayteks are running stock firmware, it's only Netgear that I've flashed to get more stability. In addition to these routers, I have also three 3COM Baseline switch 2824, and another Draytek router with Prosafe FS752TP PoE switch dedicated for VoIP phones. Wired-Draytek has IP 10.0.0.1, DHCP disabled as there is AD DC which is issuing IP addresses. Wireless-Draytek has IP 1.1.1.1 and DHCP enabled. Netgear has default - 192.168.1.1. As per suggestion, the specific question is - how do I isolate these two wireless routers?

  • libvirt's dnsmasq does not respond to dns queries or provide dhcp

    - by Jeremy
    This is on Ubuntu 10.04 server, using KVM to run Ubuntu guests. This system has been working for a long time and I have not changed anything (other than applying security updates), but today I found dnsmasq no longer responds to requests. I cannot say how long this has been broken for me because I don't frequently use the NAT'd guests. So it could have started just after the last updates or some other event and I just now found it. I can connect to port 53 with telnet at 192.168.122.1. I've flushed ip-tables to be sure it wasn't firewall rules and that is not the problem. dnsmasq is running, virsh reports default network as stared. I can't find ANY information on troubleshooting libvirt dnsmasq except that it won't play well with other instances of dnsmasq, which is not the problem. I cannot even find where log entries might be for this service. Any ideas on where to look for more information? edit to add: I added another network and that one works fine. I guess I have a workaround but would still like to figure out how to troubleshoot this problem.
