How to get Mac OS X Terminal.app and screen/vim scrolling to play nice?

- by rustychains

OSX 10.6.3 Terminal.app Am a pretty dedicated screen user. Terminal.app line buffer and/or scroll does not seem to work for me. That is while in screen anything that goes past the top of the frame is gone, can't scroll back to. This seems to work ok in other terminal apps gnome, cygwin. Perhaps this is a shell env, config, or command? .screenrc: startup_message off autodetach on shell -$SHELL vbell off defutf8 on caption always caption string "%{= wk}%w" I have tried using defscrollback here with different values, but doesn't have an effect. some .bashrc settings: set -o physical export TERM=xterm-color shopt -s checkwinsize

Different settings for secure & non-secure versions of Django site using WSGI

- by Jordan Reiter

I have a Django website where some of the URLs need to be served over HTTPS and some over a normal connection. It's running on Apache and using WSGI. Here's the config: <VirtualHost example.org:80> ServerName example.org DocumentRoot /var/www/html/mysite WSGIDaemonProcess mysite WSGIProcessGroup mysite WSGIScriptAlias / /path/to/mysite/conferencemanager.wsgi </VirtualHost> <VirtualHost *:443> ServerName example.org DocumentRoot /var/www/html/mysite WSGIProcessGroup mysite SSLEngine on SSLCertificateFile /etc/httpd/certs/aace.org.crt SSLCertificateKeyFile /etc/httpd/certs/aace.org.key SSLCertificateChainFile /etc/httpd/certs/gd_bundle.crt WSGIScriptAlias / /path/to/mysite/conferencemanager_secure.wsgi </VirtualHost> When I restart the server, the first site that gets called -- https or http -- appears to select which WSGI script alias gets used. I just need a few settings to be different for the secure server, which is why I'm using a different WSGI script. Alternatively, it there's a way to change settings in the settings.py file based on whether the connection is secure or not, that would also work. Thanks

A specific user is unable to log in to vsftpd

- by HackToHell

I am setting up a new user let his name be ftpguy. He has access to only one directory /var/www/xxx. I have already chowned the directory so that he has write and read privileges. The user is also unable to login via ssh as I have disabled that by changing his shell to /sbin/nologin. Also, in vsftpd config, I have enabled the chroot_local_user. Now whenever I log in from ftp, i get an auth error. Connect socket #1008 to xxxxxxxx, port 21... 220 Welcome to blah FTP service. USER ftpguy 331 Please specify the password. PASS ********** 530 Login incorrect. I changed the password to something different several times, using the passwd command, nothing happens, i still the above error. However I am able to log in with my ssh creditals to my ftp server without any problems.(I do not use a key).

Missing APR on apache2 ./configure

- by arby

I want to build the latest stable version of apache2. I downloaded the source and put APR & APR-util in the srclib folder, then changed directories to ./srclib/apr and ran: ./configure --prefix=/usr/local/apr sudo make sudo make install This seemed to install APR ok, but when I run ./configure from the apr-util directory, I receive the error: configure: error: APR could not be located. Please use the --with-apr option. Using ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr, the error becomes: checking for APR... configure: error: the --with-apr parameter is incorrect. It must specify an install prefix, a build directory, or an apr-config file. Why can't it find APR?

IIS7 FastCGI downloads quit at 4128760 bytes on slow connections

- by eingko

I'm using FastCGI via IIS7 to host a PHP application. For whatever reason downloads that are streamed via PHP (i.e. a script that outputs a file/bytes as a response) download perfectly fine on high-speed connections but on anything slower (even on DSL) quits at EXACTLY 4128760 bytes (~3.9MB) - which makes me think it's a configuration issue... We only started having this problem when we switched from Apache to IIS - this also points to a configuration problem, I think. But if it's a configuration issue, why would it only affect slower connections? Does anyone know where (or how) I could possibly change a setting like this? I've tried changing the idleTimeout, executionTimeout, and activityTimeout values in my web.config but this hasn't helped at all. Any help or direction would be greatly appreciated. Thanks in advance.

Postfix tutorial inconsistency

- by Desmond Hume

I'm following this tutorial to setup a Postfix/Dovecot mail server with Postfix Admin as a web front end. As regards directory structure for virtual mail users, the author of the tutorial writes: Virtual mail users are those that do not exist as Unix system users. They thus don't use the standard Unix methods of authentication or mail delivery and don't have home directories. That is how we are managing things here: mail users are defined in the database created by Postfix Admin rather than existing as system users. Mail will be kept in subfolders per domain and account under /var/vmail - e.g. [email protected] will have a mail directory of /var/vmail/example.com/me. But when he gives instructions about configuring Postfix Admin, he suggests this to be contained by Postfix Admin's config.inc.php: // Mailboxes // If you want to store the mailboxes per domain set this to 'YES'. // Examples: // YES: /usr/local/virtual/domain.tld/[email protected] // NO: /usr/local/virtual/[email protected] $CONF['domain_path'] = 'NO'; Is there an inconsistency?

Very slow disk performance on Dell PowerEdge 2950 w/ PERC 6/i running RAID 10

- by vocoder

I recently set up a server running Ubuntu 10.04 LTS on a Dell PowerEdge 2950 server - it has 6 500 gb 7200RPM SATA drives setup in a RAID 10 config. I am seeing extremely poor disk performance - the RAID array reports all disks are normal and using MegaCLI, it looks like the BBU is fine. hdparm -tT /dev/sda reports: Timing cached reads: 90 MB in 2.05 seconds = 43.96 MB/sec Timing buffered disk reads: 24 MB in 3.11 seconds = 7.72 MB/sec So as you can see, it takes forever to something as simple as an apt-get upgrade and even logging into the server. How do I go about troubleshooting what is causing this? I upgraded the firmware on the PERC 6i RAID controller to the latest, but didn't see any improvements.

Unknown protocol when trying to connect to remote host with stunnel

- by RaYell

I'm trying to set up a stunnel for WebDav on Windows. I want to connect 80 port on my local interface to 443 on another machine in my network. I can ping the machine remote machine. However when I use the tunnel, I'm getting this error all the time SSL state (accept): before/accept initialization SSL_accept: 140760FC: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol There is nothing in the logs on the other machine and here's my stunnel connection config [https] accept = 127.0.0.2:80 connect = 10.0.0.60:443 verify = 0 I've set it up to accept all certificates so this shouldn't be a problem with a self-signed certificate remote host uses. Does anyone knows what might be the problem that this connection cannot be eastablished?

Setting up SVN+SSH for multiple users through one local user.

- by Warlax

Hi, I need to make our SVN repository accessible through the firewall - but without creating a local user for each potential external user. Instead, I would like to set-up SVN+SSH to route all external users through a single local user name. We would like each external user to authenticate with SSH the regular way but then treat their instance of svnserve as if they're all that single local user and possibly, control what parts of the repository each external user can access. I know that I will need to set my svnserve config according to the official guide. I tried, but the instructions are fuzzy and I am relatively a Linux n00b. What exactly are the steps to proceed? and how would you go about testing this? Thanks for your help.

Rewrite URL based off of IP on OpenWRT

- by Scott

We are running OpenWRT on a WRT54GL. I have been looking for an answer to this, but I can't seem to figure out what to search for, if its possible, or what combination of programs to use. I want to be able to redirect a HTTP request from a WiFi device based off of their MAC address. This should all be transparent to the device. Basically we are trying to redirect any non-registered devices to a website to register the device (at this point, we would push a new config to the router that would allow this MAC address "full access"). Once a device is registered, it will be redirected to a transparent squid proxy server on another machine for caching/blocking certain sites. I looked at tinyproxy - popilo which redirects but I won't have the MAC address to know if its registered or not. Any help (google suggestions, programs, anything!) would be very much appreciated!

Passing all traffic through Cloudflare

- by Nick

I am new to Linux System Administration and I am experimenting with iptables trying to learn how to really lock down a system with them. And one thing a friend of mine recommended was that there was a way to pass all incoming traffic through Cloudflare so even if attackers resolved the server ip they still couldn't (D)dos it directly. This is exactly what they said: "Simply config your servers iptables to only allow incoming connections from CloudFlares IP ranges then set it to allow only your IP/IP range to connect on port 21 (SSH)" Could someone help me on what command I'd need to run for Ubuntu to get this effect?

Multiple PHP versions running as cgi

I'm trying to install a second version of PHP, to run alongside the current version of php. I've compiled the latest php source from github (5.5-DEV), and I'm trying to run it as CGI. Here is my virtual host config: <VirtualHost *:8055> DocumentRoot /Library/WebServer/Documents/ ScriptAlias /cgi-bin/ /usr/local/php55/cgi Action php55-cgi /cgi-bin/php-cgi AddHandler php55-cgi .php <Directory /Library/WebServer/Documents/> Options Indexes FollowSymLinks Includes ExecCGI AllowOverride All Order Allow,Deny Allow from all </Directory> DirectoryIndex index.html index.php </VirtualHost> But when I go to http://127.0.0.1:8055/info.php, I get the following error: Forbidden You don't have permission to access /cgi-bin/php-cgi/info.php on this server Edit I'm now switching between LoadModule php5_module /usr/local/php54/libphp5.so and LoadModule php5_module /usr/local/php55/libphp5.so It works for now, but is not ideal. I would like to have the different versions of php on different virtual hosts

How to create public html (apache2) with LDAP authentication?

- by borjamf

Im running Apache2 on Ubuntu 12.04 Server because I want to create a home directory for each ldap user. I'm using LDAP for authentication and it's working ok. Also I've done some tests with LDAP module for Apache2 and it's working ok. The problem with this LDAP authentication is that any success login can access to ~user/public_html, even if the user is not the owner of that home. I dont know how to control that, for example, userldap2 access to userldap1/public_html. I want that only the userldap1 access to userldap1. Could anybody tell me how to control that with LDAP authentication? I hope that you'll understand me. My config (auth_ldap.conf) <Directory /home/disco2/*/public_html> AuthName "Authentication" AuthType basic AuthBasicProvider ldap AuthzLDAPAuthoritative off AuthLDAPURL ldap://prueba.borja/dc=prueba,dc=borja?uid? Require ldap-filter objectClass=posixAccount </Directory>

Proxmox 31 + KVM routing + IP subnet + csf

- by KeyJey

We have proxmox 3.1 server in netzner with routuing network and IP subnet block. We want to implement csf firewall without interfering the traffic of the KVM VMs, what would be the easiest way? We readed that we should add this lines to /etc/csf/csfpost.sh: iptables -A FORWARD -d 144.76.223.155 -j ACCEPT iptables -A FORWARD -d 144.76.223.156 -j ACCEPT iptables -A FORWARD -d 144.76.223.157 -j ACCEPT iptables -A FORWARD -d 144.76.223.158 -j ACCEPT iptables -A FORWARD -d 144.76.223.159 -j ACCEPT iptables -A FORWARD -d 144.99.183.323 -j ACCEPT But when we enable csf the ping breaks, this is the network config (IPs are modified): auto lo iface lo inet loopback # device: eth0 auto eth0 iface eth0 inet static address 144.76.166.100 netmask 255.255.255.255 pointopoint 144.76.183.97 gateway 144.76.183.97 # for single IPs auto vmbr0 iface vmbr0 inet static address 144.76.166.100 netmask 255.255.255.255 bridge_ports none bridge_stp off bridge_fd 0 up ip route add 144.99.183.323/32 dev vmbr0 # for a subnet auto vmbr1 iface vmbr1 inet static address 144.76.166.100 netmask 255.255.255.248 bridge_ports none bridge_stp off bridge_fd 0 Thanks in advanced ! :)

How to Configure IIS 7.5 to Host Several Classic ASP Sites using 1 IP Address?

We are running Windows Server 2008 R2 with IIS 7.5 and have 4-5 Classic ASP sites to install. The main site is stored in wwwroot and the other sites are stored in folders below wwwroot. We have 1 IP address for the server. How do I configure IIS to allow folks to browse/test the sites before domain names are pointed to te server? When I setup one of the sites in a subfolder of wwwroot and assign a separate port to it, I receive a message stating: Config Error Cannot add duplicate collection entry of type 'add' with unique key attribute 'value' set to 'index.asp' How do I remedy this error and permit IIS to render the site?

Set Display Refresh Rate in OSX w/o External Utilities

- by codedonut

I have an iMac and an LG Flatron connected as a secondary monitor. The recommended resolution for the flatron is 1680x1050 @ 65.290 Hz (horiz), 59.954 Hz (vert). For some reason, OSX is choosing a slightly different set of scan rates and this is currently my best guess of why the monitor goes into power saving mode when connected to the iMac (but works fine on a PC). Now, I resolved this by installing switchResX and fudging the scan rates according to the specs in the manual. But how does one change these rates w/o 3rd party tools? Which config files need editing? Thanks

Black stripe appears to the right of the screen, impossible to get rid of

- by Gabriele Cirulli

After clicking the "Auto Config" button on my Acer AL2216w screen a stripe appeared on the right of the screen where the screen doesn't "exist" and I can't seem to take the screen viewport back even by using the OCD setting and moving it to the right. The left part of the screen is also hidden and I'm not able to see what's going on there. The PC is connected to the screen through a DVI adapter and a VGA cable. I also use multiple monitors and this is the second monitor. Anyway this seems not to be a related issue, as this used to happen even when I only had a single monitor. I managed to fix this issue once but it was more than two years ago and I can't remember what I did, and out of all of the things I've tried so far (connecting the screen to another PC and performing auto adjustment, switching the cables, etc.) none worked. Here's how it looks: Can anyone help me fix this?

Windows 2008 File Share

- by user36540

Hi, I have 3 Windows 2008 Standard servers in my system with no domain controller. Two of the servers are running a NLB cluster and the third server is a file server that the web servers connect to. I want to store my source code on the file server and point the IIS config to the network file share. The web sites also need access to a file share on the file server. I was able to share the network drive and access while logged into either of the web servers but my web apps are unable to access the file share - I assume due to permissions. Does anybody know the correct way to do this? Thanks, Chris

Mount TMPFS instead of ro /dev

- by schiggn

I am working on a ARM-Based embedded system with a custom Debian Linux based on kernel 2.6.31. In the final system, the Root file system is stored as squashfs on flash. Now, the folder /dev is created by udev, but since there is no hot plugging functionality needed and booting time is critical, I wanted to delete udev and "hard code" the /dev folder (read here, page 5). because i still need to change parameters of the devices (with ioctl /sysfs) this does not work for me in this case. so i thought of mounting a tmpfs on /dev and change the parameters there. is this possible? and how to do best? my approach would be: delete /dev from RFS create tar containing basic devices mount tmpfs /dev untar tar-file into /dev change parameters Could this work? Do you see any problems? I found out, that you can mount on top of already mounted mount point, is it somehow possible just to take data with while mounting the new file system? if so that would be very convenient! Thanks Update: I just tried that out, but I'm stuck at a certain point. I packed all my devices into devices.tar, packed it into /usr of my squashfs and added the following lines to mountkernfs.sh, which is executed right after INIT. #mount /dev on tmpfs echo -n "Mounting /dev on tmpfs..." mount -o size=5M,mode=0755 -t tmpfs tmpfs /dev mknod -m 600 /dev/console c 5 1 mknod -m 600 /dev/null c 1 3 echo "done." echo -n "Populating /dev..." tar -xf /usr/devices.tar -C /dev echo "done." This works fine on the version over NFS, if I place printf's in the code, I can see it executing, if I comment out the extracting part, its complaining about missing devices. Booting OK mmc0: new high speed SDHC card at address 0007 mmcblk0: mmc0:0007 SD04G 3.67 GiB mmcblk0: p1 IP-Config: Unable to set interface netmask (-22).

It's telling me while booting that it is unable to open an initial console and its throwing errors on mounting the UBIFS devices, but finally provides a login anyway. Over that my echo's are not executed. If I then log in, /dev is mounted as TMPFS as desired and all the devices reside inside. When I redo the "mount" command to mount the UBIFS partitions it is executed whitout problem and useable. From squashfs VFS: Mounted root (squashfs filesystem) readonly on device 31:15.

Does anyone has a clue why? Other question, is 5MB enough/too much for /dev?
