• How to repair unbootable Fedora install

  - by Cerin

  How do you repair/reinstall Fedora without deleting any existing partitions or data? I was attempting to upgrade some old Fedora 13 servers to 17, following the instructions in the wiki. After the 14-15 upgrade, rebooting resulted in the output: Dropping to debug shell. sh: can't access tty; job control turned off dracut:/# Running dmesg also shows: dracut Warning: No root device "block:/dev/mapper/VolGroup-lv_root" found Googling shows this error is typically related to some weird RAID issues, but my server is a virtual machine not using any RAID. Using a rescue CD, I can chroot /mnt/sysimage, and all packages and data still seems to be there. How do I make the system bootable again?

• Installing SSL certs with nginx on Amazon EC2

  - by Ethan

  I finally got a cert from an authority and am struggling to get things working. I've created the appropriate combined certificate (personal + intermediate + root) and nginx is pointing to it. I got an elastic IP and connected it to my EC2 instance. My DNS records point to that IP. But when I point the browser to the hostname, I get the standard "Connection Untrusted" bit, with ssl_error_bad_cert_domain. Port 443 is open - I can get to the site over https if I ignore the warning. Weird thing is, under technical details, it lists the domain I tried to access as valid! When I try and diagnose with ssl testing sites, they don't even detect a certificate! What am I missing here? domain is yanlj.coinculture.info. Note I've got coinculture.info running on a home server without a dedicated IP and have the same problem, but I'll be moving that to the same EC2 instance as soon as I figure this thing out. I thought the elastic IP would solve things but it hasn't

• Nginx Restart Issues

  - by heavymark

  All of the sudden when restarting Nginx I get the following error: Restarting nginx: [alert]: could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied) 2011/02/16 17:20:58 [warn] 23925#0: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1 the configuration file /etc/nginx/nginx.conf syntax is ok 2011/02/16 17:20:58 [emerg] 23925#0: open() "/var/run/nginx.pid" failed (13: Permission denied) configuration file /etc/nginx/nginx.conf test failed On the front end part of the site loads but some files such as the CSS in particular are not loading. They exist on the server but when loading the resources directly in Chrome they say "Oops this page can't be found." I set a special group and user to run my apache files using suexec for my domain files. I think the nginx are owned by root however which I'm assuming is the problem but which nginx file ownerships would I change?

• Wordpress multisite and redirect

  - by Dr I

  I come to you because I'm facing a really strange effect on my hosting. I currently manage a server contening a NGINX/PHP-CGI and a wordpress multisite in it. My sites are created using subsite.domaine.tld, for now, my three subsites are correctly accessibles through the url: subsite.domain.tld. My goal is to allow my subsite on the host domain to be access through their respective unique domain. For exemple: www.domainA.com would redirect to subsite1.host.domain.tld. If I do that using the following setting on the domainA Public DNS: www 10800 IN CNAME subsite1.host.domain.tld. When I try to access www.domainA.com I don't go to subsite1.host.domain.tld but instead I'm redirect to the Wordpress ROOT site where I create my Network (host.domain.tld). Is there a trick to deal with?

• Redhat 6 gui installation VS kickstart gives me different packages?

  - by jonaz

  If i do the graphical install and select basic server + aide and screen i get a system with 535 installed packages. If i look at the /root/anaconda-ks.cfg file in that freshly installed system i see: %packages @base @console-internet @core @debugging @directory-client @hardware-monitoring @java-platform @large-systems @network-file-system-client @performance @perl-runtime @security-tools @server-platform @server-policy @system-admin-tools pax python-dmidecode oddjob sgpio certmonger pam_krb5 krb5-workstation nscd pam_ldap nss-pam-ldapd perl-DBD-SQLite aide screen If i then install a NEW system using a kickstart only containing those packages i get 620 installed packages. So basicly my question is why does the system install almost 100 more packages when using kickstart compared to the GUI installation when the exact same packagegroups are selected?

• How secure is a bluetooth keyboard against password sniffing?

  - by jhs

  In a situation where an admin will enter sensitive information into a keyboard (the root password), what is the risk that a bluetooth keyboard (ship by default with Mac systems these days) would put those passwords at risk? Another way of asking would be: what security and encryption protocols are used, if any, to establish a bluetooth connection between a keyboard and host system? Edit: Final Summary All answers are excellent. I accepted that which links to the most directly applicable information however I also encourage you to read Nathan Adams's response and discussion about security trade-offs.

• Why can't windows see mmcblk0p3? [closed]

  - by jacknad

  The partition is created on the embedded linux target like this # n - new # p - partition # 3 - partition 3 # 66 - starting cylinder # <blank> - maximum size for the ending cylinder # t - set file system type # 3 - partition 3 # c - set to windows vfat # w - write partition table and exit echo -e "n\np\n3\n66\n\nt\n3\nc\nw" | fdisk /dev/mmcblk0 The file system is then formatted on the embedded linux target as MS-DOS like this # -n volume-name # -F FAT-size mkfs.vfat -n DB -F 32 /dev/mmcblk0p3 A linux host can mount and access files in mmcblk0p3 without issue. Why can't windows? Edit: Although the default number of FATS is 2 I tried adding -f 2 [number-of-FATs] since this is actually being done by busybox on an embedded platform but this didn't help. I understand the Linux MS-DOS file system does not support more than 2 FATs but there are only 2 on this target (the boot is also FAT which is visible), along with and EXT3 (on p2) for the root file system.

• Install Git on my Media Temple (dv) 4.0 server

  - by Chris

  I'm trying to install Git on my Media Temple (dv) 4.0 server. I've followed these instructions: http://wiki.mediatemple.net/w/%28dv%29_4.0:Install_GIT It seems to have "installed", as there are a boat load of files in the following directory: /root/git-2012-06-06 However, when I perform any git command in the server: git: command not found My assumption is that something, somewhere isn't configured properly, but I have no idea where to start. Could anybody lend a hand / offer some pointers? (And if you hadn't guessed, I'm pretty new to all this, so please be kind!) Thanks very much Chris

• Can a truecrypt container be moved on Fedora Linux?

  - by Thayananthan Narayanan

  I have created a truecrypt container (100GB) to store very important files with vital information hidden on my hardrive running Fedora Linux OS. Now, I want to move the container to portable hardrive. From what I read so far, you should be able to do it easily like any other file. However, I am running into problem. Fedora won't let me. It keeps giving me "Permission denied" error. I think I need to login as a root or superuser, but how do you do that on Fedora. What am I doing wrong?

• how to limit upload bandwidth per user in linux?

  - by Gihan Lasita

  Can anyone provide the tc command to limit upload bandwidth per user in Debian Lenny? I found that to mark packets per user with iptables I can use the following command iptables -t mangle -A OUTPUT -p tcp -m owner --uid-owner testuser -j MARK --set-mark 500 but I have no idea how to use tc update by running following commands, i managed to limit testuser upload bandwidth to 10Mbit iptables -t mangle -N HTB_OUT iptables -t mangle -I POSTROUTING -j HTB_OUT iptables -t mangle -A HTB_OUT -j MARK --set-mark 30 iptables -t mangle -A HTB_OUT -m owner --uid-owner testuser -j MARK --set-mark 10 tc qdisc replace dev eth0 root handle 1: htb default 30 tc class replace dev eth0 parent 1: classid 1:1 htb rate 10Mbit burst 5k tc class replace dev eth0 parent 1:1 classid 1:10 htb rate 10Mbit ceil 10Mbit tc qdisc replace dev eth0 parent 1:10 handle 10: sfq perturb 10 tc filter add dev eth0 parent 1:0 prio 0 protocol ip handle 10 fw flowid 1:10 now the problem is, i do not want to limit testuser's FTP bandwidth but by running above commands FTP speed also limited to 10Mbit.

• How do I prevent libvirt from adding iptables rules for guest NAT networks?

  - by Jack Douglas

  Similar to this old request on BugZilla for Fedora 8, I'm hoping something has changed since then or someone knows another way. I want to manage the iptables rules by hand—the one-size-fits-all automatic rules don't suit me at all. These rules seem to be added and removed when a network is started and destroyed. Is there a way of either preventing these rules being added at all or hooking a script into the network start that restores the default rules afterwards. For now, I'm using a very crude method with cron, but I hope there is a better way: * * * * * root iptables-restore < /etc/sysconfig/iptables

• Nginx Rewrite to Previous Directory

  - by ThinkBohemian

  I am trying to move my blog from blog.example.com to example.com/blog to do this I would rather not move anything on disk, so instead i changed my nginx configuration file to the following: location /blog { if (!-e $request_filename) { rewrite ^.*$ /index.php last; } root /home/demo/public_html/blog.example.com/current/public/; index index.php index.html index.html; passenger_enabled off; index index.html index.htm index.php; try_files $uri $uri/ @blog; } This works great but when i visit example.com/blog nginx looks for: /home/demo/public_html/blog.example.com/current/public/blog/index.php instead of /home/demo/public_html/blog.example.com/current/public/index.php Is there a way to put in a rewrite rule so that I can have the server automatically take out the /blog/ directory? something like ? location /blog { rewrite \\blog\D \; }

• Best way to bring a system down with a "maintenance" message?

  - by iftrue

  What's the best way to bring down an apache2/tomcat6 setup for maintenance? Specifically, apache2 can stay running, but tomcat needs to restart to accomplish a number of tasks. My initial thought is to change the root directory in the httpd.conf VirtualHost entry to point to a new location, then issue a force-reload command to direct traffic away from the actual tomcat application. After some period of time, I perform tomcat maintenance, switch the VirtualHost entry, and force-reload to begin directing traffic back. Is there a better way to do this? I'm looking to start work on a rather extensive web application, and my deployment procedure right now involves shutting everything down and bringing everything back up. Is there a better way to do this than what I've proposed?

• Watch videos from a remote computer on the LAN on ubuntu

  - by tapan

  I want to watch the videos on a friends computer on the LAN without having to download it. Both of us are running ubuntu. Now one way is to ssh to his computer, cd to the directory where the video is and run the falling command: cat video.avi | ssh me@mycomputer mplayer - This works. However the problem is that I cannot seek inside the video as in can't go forward or backward in it. Is there a method by which I can watch the videos and also seek in them ? I can install any software on his comp and my comp to aid this process. I have root level access on both computers. Any suggestions ?

• SHH Tunnel for Remote Desktop via Intermediary Server

  - by Mihai Todor

  I've seen many examples of SSH tunnels on the nets, but I'm still having no luck with this. Here's the setup: Windows 7 PC in a private network, sitting behind a firewall, with PowerShellInsider SSH server set up and working fine. Public access Linux server, which has access to the PC. Windows 7 laptop, at home, from which I wish to do remote desktop on the PC. Now, here's what I've tried so far: SSH tunnel from my laptop to the Linux server: ssh -f my_user@LINUX_SERVER -L 6666:LINUX_SERVER_IP:6666 -N SSH to the Linux server where I've set up a tunnel to the PC: ssh -f 'PRIVATE_DOMAIN\my_user'@PC_NAME -L 6666:PC_IP:3389 -N Unfortunately, I must be doing something wrong, because it doesn't seem to work. Any ideas why or, at least, any suggestions on how can I try to debug this setup? At the moment, I have access to all 3 machines (non-root on Linux), so I can test whatever I want...

• How to recover data from software RAID 5 disk partition

  - by Ali n

  I have CentOS 5.8 on my computer, with 5x 1TB hard drives. I used software RAID. (RAID 1 as a boot partition md0, RAID 0 as a root partition md1 and RAID 5 as /home partition md3). Unfortunately one of these hard drives failed lately and I want to replace it with a new one. I want to know that is it possible to change this hard drive without data loss? The important partition is RAID 5 so in theory if one of hard drives failed I should be able to recover its data without any problem. But in practice how can I do that?

• First time setting up a MySQL database.

  - by Wilduck

  In trying to learn how to work with the LAMP stack, I've hit a wall with MySQL. I can't seem to find a good reference for the first time setup of MySQL to be used with Apache and python. So, my question is four-fold: 1) Under what circumstances should I create my first database. That is, what user do I use (Apache's http user? root?) 2)How do permissions work? 3) Do I have to do anything on the MySQL side to make MySQL talk to Apache, or MySQL to talk to Python/Django? 4) Is there a good resource online that describes setting all of this up? I've found a bunch for using a database once it's in place, but none for the initial setup? Notes: I'm trying to run my LAMP stack on a dedicated little box for testing/learning purposes only, so I don't have access to any DBA that could help me, as much as I'd like one.

• Getting Pango-WARNING: Invalid UTF-8 string passed to pango_layout_set_text()

  - by geerlingguy

  About three days ago, I noticed the exim mailqueue started filling up on one of my servers, and upon inspecting some of the emails using # exim -Mvb $ID, I noticed they were being sent to some system email address (which is not a real address), and the body of the messages were as follows: (process:8259): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text() I'm wondering what could be causing this strange issue, as I've never heard of 'pango' at all... I've never seen that function used in my lifetime! It seems the process id (PID) is for an apache process, though, as the pids are always gone by the time I use # ps -aux to look them up. Edit: Whoops! Forgot to include the subject - looks like it's actually munin-cron that's bringing up the issue: Subject: Cron /usr/bin/munin-cron --force-root

• Free DNS software with failover support?

  - by Lin

  I'm looking for DNS software that can accomplish the following: Check health of all A records at set intervals If server is unresponsive after multiple successive checks, replace A record with a working server When a server is down, check it periodically. Once it's up, restore normal A records Here's an equivalent I thought of: Run DNS servers with very low TTL (minutes) Use a cron job to periodically query all webservers Use sed to replace A records if need be, and then restart DNS server I have a hard time believing there isn't already something that can accomplish the above. I'm not looking for a paid service, and I'm restricted to anything I can run with root access to a VPS. Any suggestions would be great. Thanks!

• Unix domain socket firewall

  - by lagab

  Hello, everyone. I've got a problem with my debian server. Probably there is some vulnerable script at my web-serser, which is running from www-data user. I also have samba with winbind installed, and samba is joined to windows domain. So, probably this vulnerable script allows hacker to bruteforce out domain controller through winbind unix domain socket. Actually I have lots of such lines at netstat -a output: unix 3 [ ] STREAM CONNECTED 509027 /var/run/samba/winbindd_privileged/pipe And our DC logs contain lots of recorded authentication attems from root or guest accounts. How can I restrict my apaches access to winbind? I had an idea to use some kind of firewall for IPC sockets. Is it possible?

All systems run linux and have root acces to all. Need securely rsync internal_server_1:/some/path into internal_server_2:/another/path My idea is make ssh secure tunnel between two firewalls, e.g. from firewall_1 firewall1# ssh -N -p 22 -c 3des user2@firewall_2.example.com -L xxx/10.3.0.3/xxxx and after will run rsync from internal_server_1 somewhat like: intenal1# rsync -az /some/path [email protected]:/another/path I don't know how to make a correct ssh tunnel for rsync (what ports need tunnel) and to where i will make the rsync? (remote comp address in case of ssh tunnel) Any idea or pointer to helpfull internet resource for this case? thanx.
