  • Apache: how to set custom 401 error page and save original behaviour

    - by petRUShka
    I have Kerberos-based authentication with Apache/2.2.3 (Linux/SUSE). When user is trying to open some url, browser ask him about domain login and password like in HTTP Basic Auth. If user cancel such request 3 times Apache returns 401 Authorization Required error page. My current virtual host config is <Directory /home/user/www/current/public/> Options -MultiViews +FollowSymLinks AllowOverride None Order allow,deny Allow from all AuthType Kerberos AuthName "Domain login" KrbAuthRealms DOMAIN.COM KrbMethodK5Passwd On Krb5KeyTab /etc/httpd/httpd.keytab require valid-user </Directory> I want to set nice custom 401 error page with some instructions for users. And I added such line in virtual host config: ErrorDocument 401 /pages/401 It works, when user can't authorize apache redirects him to my nice page. But Apache doesn't ask user login\password as it did before. I want this functionality and nice error page simultaneously! Is it possible to make it works properly?

  • Migrate IMAP account between providers - client access only

    - by Pekka
    I have an IMAP E-Mail account with my old provider. I have a new, empty IMAP account with the new provider. Is there a tool or Thunderbird to migrate the E-Mail data from one account to another? I'm a bit wary about just doing a drag & drop in Thunderbird because it's quite a lot of data, and I have a deep distrust against how Thunderbird deals with IMAP data.

  • Command-line HTTP crawler for Windows?

    - by Pekka
    Would somebody have a recommendation for a web site crawler that can be invoked and equipped with settings from the command line? This would need to run in a Windows environment. Saving the data, following stylesheet links etc. is not an issue. I only need the crawler to start with a page, parse it, and follow all the links on the same domain so that in the end, all pages on the site have been requested once. Background: I'm setting up a web site that gets frequently uploaded from an office location. Combining data from various sources, it has several levels of caching. I don't want the first user to visit the site after a fresh upload to have to wait until the page has been generated and saved in the cache.

  • Need to setup a RADIUS server to authenticate a Windows client to a Windows server

    - by drosenblatt
    I have a server that I have technicians who need to be able to access using shared credentials. However, doing that violates our security policy (!). I need each user to be able to authenticate using their own credentials, but the server in question has to be logged in with a certain login (these two requirements are clearly diametrically opposed). I thought that this would be a great application for a RADIUS server. I know how to setup RADIUS to go from Windows -- Cisco, but I have no idea how to use RADIUS to authenticate Windows -- Windows. Can this be done? If so, how?

  • Managing multiple IMAP accounts in Thunderbird

    - by baritoneuk
    I've been using Thunderbird for years without issues with 20+ pop3 accounts. I'm moving over to imap which will enable me to keep copies of the emails locally and on the server whilst keeping everthing synchronised. However I'm looking for the best way to manage multiple imap accounts on Thunderbird. Currently I have a filter that copies all the emails into a central inbox and into seperate local folders. The reason for this is I go through my inbox daily and delete all emails that don't require any action. I move any emails that require action to my "action" imap account folder. This way I can syncronise all the emails that require action across multiple computers (and mobile devices). This technique is my implemantion of the GTD or Getting things Done philosophy. I also copy over each email into seperate local folders. The reason I do this is just in case any emails on the imap accounts get deleted, or something drastic happens on the server which means I lose all the emails. My business partner has access to some of these emails and still uses pop3 (with "leave copy on server" checked), but I know sometimes Thunderbird can still delete emails off the server sometimes. The problem with the above is that thunderbird gives me the dreaded error dialogue saying that the emails cannot be filtered due to another process. I find the folder list in Thunderbird hard to manage. Here is a screenshot of part of my folder list- as you can see it's a bit of a complicated list and not easy to manage: What would be the best way of me managing multiple imap accounts whilst allowing me to have copies put in a central folder and emails in local folders? It would be useful if people think this is necessary, as perhaps there is a betterway? How do people manage multiple imap accounts in a way that allows them to keep on top of actionable emails? I'd be interested in how others manage this. I've never used the Thunderbird-based client "Postbox", does this handle multiple imaps better?

  • SQL Server 2000 Client won't connect

    - by alimack
    One day instead of connecting to the database my SQL Server Management gave me the following error: "Data Source name not found & no default driver found" Note it had been working for several years before this, all that had changed was an upgrade to Office (97 -2000) and the monthly Windows patches. I tried rebooting, re-installing both the SQL Server 2000 and 2005 clients on the machine but no joy. I can access the database(s) from other machines.

  • How to setup terminal service gateway in my RDP client

    - by Stan
    I am using "RD Tabs" to bypass the terminal service gateway to RDP to the remote host. Usually I use browser and go to https://webvpn.company.com:777 with my account. Now in RD Tabs advanced settings, it's asking server name and authentication method. How should I fill this information? I tried below: server: webvpn.company.com:777 authentication: Attempt TLS But it's not working, what could be wrong? Thanks.

  • PXE Boot PCLinuxOS ISO

    - by DBNotCooper
    I'm in the process of trying to convert some computers at my local school to be diskless browser stations. We've identified PCLinuxOS as the OS we'd like to use due to it's easy interface for creating custom ISO images (we need WINE and some custom apps installed also, as well as FireFox). I've been having problems figuring out how to get an ISO to boot via PXE. In our network, I only have access to TFTP and HTTP, so I cannot use NFS. The machines all have enough memory (4 gigs) that they could use a ram drive to hold the ISO image, if that helps. Currently I've been looking at GPXE with GRUB/MEMDISK, but I don't know if that's the right solution, or even where a good resource is for setting it up. Searching the web has proved fruitless, as most of the information is either NFS-specific or out of date. The other students and I would appreciate any help! :)

  • issue using Postfix as authen SMTP client relay to Exchange 2010

    - by Gk
    Hi, I'm using postfix to relay mail to Exchange 2010. Here is my config: relayhost = [smtp.exchange.2010] smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/relay_passwd smtp_sasl_security_options = #smtp_sasl_mechanism_filter = ntlm (/etc/postfix/relay_passwd contains login information of some accounts on Exchange) With this configuration I can relay email to Exchange. The problem is: the message send from Postfix has header: X-MS-Exchange-Organization-AuthAs: Anonymous and the message is treated like unAuthenicated message on Exchange system (i.e when sending to distribution group require senders are authenicated, I received error: #550 5.7.1 RESOLVER.RST.AuthRequired; authentication required ##rfc822;[email protected]). I using Outlook with the same account as in Postfix and it can send without problem. The different I realized between two case is: Outlook send with NTLM auth mech, Postfix using LOGIN mech. Any idea?

  • rpd over https using a linux client

    - by Nils
    My employer switched from vpn and rdp to using what our admin calls "rdp over https". Since that switch I find myself unable to connect to the "new" rdp server. I think the progress is as follows: A rdp gateway-server is connected via tls the requested sever (different from the gateway-server) is then connected through the tls connection. In windows mstsc-settings the server name is the "internal network name" of the machine I wish to connect. And on the last tab (in German it is called "leistung" - could be activity) I go to the "connection from everywhere" settings and set the gateway-server under gateway-server. Now: Is there any way to use this scenario under linux (apart from a virtual machine running Windows)? I am interested in free ideas (e.g. is it possible to create a tls tunnel and connect through that using freerdp/rdesktop?) non-free ideas. As long as they work I'll worry about the costs later. Free ideas would be better :-)

  • ASP.NET website http requests appear to be queueing

    - by scolemann
    We cloned our servers this weekend into a colo. All non-asp.net sites are performing great, but ASP.NET sites are very slow. It appears to be an issue with the requests/connections, but I cannot figure out where. The reason I think it is a problem with the connections is that when I launch fiddler and watch the requests, all requests appear to happen sequentially. Even the static image requests are taking 5 seconds and another one doesn't start until the first one finishes. MaxConnections is set to 100 in machine.config and the "website connections" are set to unlimited. Any idea what else coudld be causing this? from machine.config:

  • Blocking HTTP clients which request certain URLs repeatedly

    - by Guido Domenici
    I run a website on Windows Server 2008 R2. Looking through the IIS logs, I have noticed that there are some IP addresses repeatedly requesting certain URLs (such as for example /mysql/phpmyadmin/main.php, /phpadmin/main.php) which do not exist, as the site is entirely served off of ASP.NET. They are obviously fishing for known vulnerabilities. My question is, are there any firewall or other tools (Windows built-in or commercial) that allow me to block those IP addresses which request certain URLs multiple times?

  • How to ignore query parameters in web cache?

    - by eduardocereto
    Google Analytics use some query parameters to identify campaigns and to do cookie control. This is all handled by javascript code. Take a look at the following example: http://www.example.com/?utm_source=newsletter&utm_medium=email&utm_ter m=October%2B2008&utm_campaign=promotion This will set cookies via JavaScript with the right campaign origin. This query parameters can have multiple and sometimes random values. Since they are used as cache hash keys the cache performance is heavily degraded in some scenarios. I suppose there's a not so hard configuration on cache servers to just ignore all query parameters or specific query parameters. Am I right? Does anyone know how hard is it in popular web cache solutions, to create ? I'm not interested in a specific web cache solution. It would be great to hear about the one you use.

  • Nobody nogroup on ubuntu client with Solaris server

    - by user1574623
    I have an openIdiana server with ZFS and it has been shared with NFS on a ubuntu server (called server1) one year ago. Now i am asked to shared it on a second ubuntu server (called server2). So i have took the line in /etc/fstab from server 1 and add it in server2: 192.168.1.22:mypool/data/.zfs/snapshot /mnt/zfs nfs acl,intr,noatime 0 0 But when i mount it, the rights on server2 are "nobody nogroup" (connect as anonymous?!) whereas its ok on server1. And on my OpenIndiana, I haven't found where it is configured (its not me who configured it last year). So I have tried to set zfs set sharenfs=rw numpool/data but without success. So i am looking for a file like /etc/exports on Ubuntu to configure which server is allowed to connect, and not as anonymous. Any idea? thanks,

  • How to troubleshoot intermittent and irregular connection errors on home network (preferrably Mac client)

    - by Martin
    Hi, I'm experiencing intermittent connection errors in our home network from two different computers, normally "Connection Reset" when browsing, but also other issues such as very slow throughput. I have approximately a network setup as below: ISP-Cable Modem-Dlink DIR 655 Router-(Ethernet)-Fon Router-Mac/Windows laptop Basically, is there a simple way to monitor the network and detect where issues are coming from? Right now we don't know if it is the Fon router, the Dlink router, the modem or the ISP. As the issue is intermittent, is there a software that regularly traceroutes a set of destinations and tests e.g. throughput, something that can help us figure out where in the chain the errors are introduced? The more automatic network monitor, the better.

  • How do I protect large file downloads through PHP and/or Apache?

    - by Eric
    We have some large files (1-8GB) that are not publicly accessible. Currently we're serving them up through a PHP script that buffers the files in 1MB chunks and writes it to the output. It's incredibly CPU intensive and slows the server down when only a few downloads are active. We want to move the file transfer work to Apache or a more efficient method. We are using cookie authentication. FTP downloads are out unless there's some way to authenticate FTP sessions through the existing PHP session cookie. Ideally we'd like something where we can use PHP to hide the link to the file while it passes off the file transfer work to Apache, which is no doubt far more efficient at HTTP file transfers than PHP. We want to be able to resume downloads as well. Any help is appreciated.

  • How to configure Postfix client relay to Exchange 2010 server

    - by helcim
    I'm getting (delivery temporarily suspended: SASL authentication failed; server myserver.com[xxx.xxx.xxx.x] said: 535 5.7.3 Authentication unsuccessful) when I try to relay mail from Postfix 2.5.5-1.1 on Debian Lenny box to Exchange 2010. I think I tried all possible combinations but I'm definitely missing something. Here is relevant part of main.cf: broken_sasl_auth_clients = yes smtp_sasl_auth_enable = yes smtp_sasl_security_options = noanonymous smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_pix_workarounds = smtp_sasl_type = cyrus smtp_always_send_ehlo = yes relayhost = myserver.com And I got libsasl2-modules installed. Anybody managed to successfully relay mail between Postfix and Exchange? Oh, and I already double-checked if password is right.

  • Recommend an SFTP solution for Windows (Server & Client) that integrates well with Dreamweaver

    - by aaandre
    Could you please recommend a secure FTP solution for updating files on a remote windows server from windows workstations? We would like to replace the FTP-based workflow with a secure FTP one. Windows Server 2003 on the remotely hosted webserver, WinXP on the workstations. We manage the files via Dreamweaver's built-in FTP. My understanding is Dreamweaver supports sFTP out of the box so I guess I am looking for a good sFTP server for Windows Server 2003. Ideally, that would not require cygwin. Ideally, the solution would use authentication based on the existing windows accounts and permissions. Thank you!

  • FTP Upload works from local command line / remote GUI client but not from PHP script

    - by MrOodles
    I originally posted this question at StackOverflow, but I'm beginning to think it's more of a server question. I have installed ProFTPd on an EC2 instance running Ubuntu 10.10. I have managed my proftpd.conf file as well as my server permissions to be able to connect and upload/move files using FTP both remotely using Filezilla, and on the server itself when connecting to 127.0.0.1. The problem I'm running into is when I try to upload/install a file using Joomla's interface. I give Joomla the same login information that I give to Filezilla, and the connection is made in the same fashion. The ftp.log file actually shows that Joomla is able to login to the server: localhost UNKNOWN nobody [17/Jan/2011:14:09:17 +0000] "USER ftpuser" 331 - localhost UNKNOWN ftpuser [17/Jan/2011:14:09:17 +0000] "PASS (hidden)" 230 - localhost UNKNOWN ftpuser [17/Jan/2011:14:09:17 +0000] "PASV" 227 - localhost UNKNOWN ftpuser [17/Jan/2011:14:09:17 +0000] "TYPE I" 200 - localhost UNKNOWN ftpuser [17/Jan/2011:14:09:17 +0000] "STOR /directory/store/location/file.zip" 550 - But it fails when attempting the STOR command. I have traced the problem in the Joomla code to the PHP FTP module. The code (with my trace statements added): if (@ftp_put($this->_conn, $remote, $local, $mode) === false) { echo "\n FTP PUT failed."; echo "\n Remote: $remote ; Local: $local ; Mode: $mode - Either ASCII: ".FTP_ASCII." or Binary: ".FTP_BINARY; echo "\n The user: ".exec("whoami"); JError::raiseWarning('35', 'JFTP::store: Bad response' ); return false; } Trace ouputs: FTP PUT failed. Remote: /directory/store/location/file.zip ; Local: /tmp/phpwuccp4 ; Mode: 2 - Either ASCII: 1 or Binary: 2 The user: www-data And in case you were curious, here is an example of the FTP log when using Filezilla: my_client_ip UNKNOWN nobody [17/Jan/2011:16:45:55 +0000] "USER ftpuser" 331 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "PASS (hidden)" 230 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "OPTS UTF8 ON" - - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "PWD" 257 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "TYPE I" 200 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "PASV" 227 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "MLSD" 226 3405 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:06 +0000] "CWD location" 250 3405 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:06 +0000] "PWD" 257 3405 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:06 +0000] "PASV" 227 3405 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:07 +0000] "MLSD" 226 3757 my_client_ip UNKNOWN nobody [17/Jan/2011:16:46:37 +0000] "USER ftpuser" 331 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "PASS (hidden)" 230 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "OPTS UTF8 ON" - - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "CWD /location" 250 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "PWD" 257 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "TYPE I" 200 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "PASV" 227 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:39 +0000] "STOR file.zip" 226 125317 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:39 +0000] "PASV" 227 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:39 +0000] "MLSD" 226 497
