• Telnet works from desktop but not Server

  - by Joe Estes

  Sending mail via smtp.gmail.com is failing on my server. I looked on some forums and people were saying to make sure you can telnet to the smtp address first. When I telnet from my server i input this and get this error: [root@localhost ~]# telnet smtp.gmail.com 465 telnet: smtp.gmail.com: Temporary failure in name resolution smtp.gmail.com: Host name lookup failure From my OS X desktop I do the same and get this: Macintosh-3:~ joe$ telnet smtp.gmail.com 465 Trying 74.125.127.109... Connected to gmail-smtp-msa.l.google.com. I'm running a fedora core 9 server with a firestarter firewall. I have turned off the firewall and the same error persists. I'm also using port forwarding from my router to this server. I have allowed forwarding for port 465 on my router as well. Can someone please help. Thanks, Joe

• Editing .bash_profile file not taking effect

  - by Sandeepan Nath

  I need to put export PATH=$PATH:/opt/lampp/bin to my ~/.bash_profile file so that mysql from command line works on my system. Please check mysql command line not working for further details on that. I am working on a fedora system and logged in as root user. If I run locate .bash_profile then I get these:- /etc/skel/.bash_profile /home/sam/.bash_profile /home/sohil/.bash_profile /home/windows/.bash_profile /root/.bash_profile So, I modified the /root/.bash_profile file like this:- from PATH=$PATH:$HOME/bin export PATH to PATH=$PATH:/opt/lampp/bin export PATH But, still the change is not taking effect - Opening a new console and running mysql again says bash: mysql: command not found. However running export PATH=$PATH:/opt/lampp/bin in console makes it work for that session. So, I am doing something wrong with the .bash_profile file. May be editing incorrect one or doing the edit incorrectly.

• Tips and tricks to make NX server more stable

  - by gareth_bowles

  My shop has been using the FreeNX server on Fedora 11 for a while now and mostly getting good results, especially with performance, but we have some annoying problems with client connections. There are two main issues: Client sessions sometimes freeze after a long time (seems to be at least 2 hours of having the session active) We often have to make multiple attempts to start a new client session, especially if a previous session was suspended rather than terminated. In qwuite a few cases, we've had to restart the NX server to get around this. Our NX server configuration is the default except that we've enabled logging level 7 to /var/log/nxserver.log, and set the font server to "unix:/7100" so that it uses xfs. Does anyone have any ideas for making things more stable ?

• PHP fopen fails - does not have permission to open file in write mode

  - by George

  I have an Apache 2.17 server running on a Fedora 13. I want to be able to create a file in a directory. I cannot do that. Whenever I try to open a file with php for writing fopen(,'w'), it tells me that I don't have permission to do that. So i checked the httpd.conf file in /etc/httpd/conf/. It says user apache, group apache. So I changed ownership (chown -R apache:apache .*) of my whole /www directory to apache:apache. I also run chmod -R 777 * Apart from knowing how terribly dangerous this is, it actually still gives me the same error, even though I even allow public write!

• mounts aren't case-sensitive

  - by Asi

  I mounted a few drives from Linux boxes in my network, but those mounts aren't case-sensitive. The mount command I used ( from the man mount.cifs, case-sensitive should be the default ): mount //10.0.1.10/remote_folder /local_folder -t cifs -o username=xxxx,password=xxxx but those mounts aren't sensitive. for example doing: ls -l /local_folder/testfile.txt ls -l /local_folder/TESTFILE.TXT give's the same result... instead of 'file not found' Couple of important points: All drives are running on Linux machines. My local machine is running Fedora 18 and it is case-sensitive for ANY folder/file expect the mounted drives. All drive/mounts are case-sensitive when when doing SSH. So if I SSH from my local machine to a remote machine, doing ls -l /local_folder/TESTFILE.TXT will say file not found as it should. So I believe the issue is in my local machine and not in the way I did the mount. but I'm not sure where to look next (I'm new to Linux)

• What are those white circles on the desktop in Gnome 3?

  - by monk

  I have Fedora 20 with GNOME 3.10.2. On the desktop background (i.e. where the wallpaper is), there are five small white circles centered at the very bottom of the screen. The first is filled, the others are not. I can click those circles, thereby changing which one is filled, like a radio button. I cannot for the life of me figure out what those circles are supposed to do, and it's starting to drive me crazy. Clicking and thus changing which circle is filled does nothing I can perceive, and there seems to be no configuration option anywhere that has anything to do with them. What are those things? Is there any way to get rid of them? Edit: I made a screenshot of my desktop with no programs running. You can see the dot/circle thingies at the bottom.

• Network on linux server is periodically down

  - by Fabian

  I have an old server running Fedora 4 that occasionally just stops responding via network for about an hour. This happens 1-2 times a week. Also no connection from the server itself to any other computer on the network is possible when it happens. The network settings and routes look fine. There are no unusual log messages and no unusual processes running at that time. If I restart the network or just do an ifconfig eth0 down & ifconfig eth0 up it works fine afterwards. I know that the server should be updated to a currently supported OS, but that is not really an easy option right now. Any ideas on how I could diagnose and fix that problem?

• Unable to log into samba server

  - by Paddington

  I am unable to log into a samba server (running on fedora core 6) as it prompts for a username and password when I try to connect to the mapped drives from my windows 7 machine. I decided to reset the password using the command smbpassword paddy and when I list users using check the pdbedit -L -v I see that the password was updated at the time I made this change. However, I am still unable to log in. The log file in /var/log/samba/log.paddy shows: [2012/10/11 09:55:54.605923, 1] smbd/service.c:678(make_connection_snum) create_connection_server_info failed: NT_STATUS_ACCESS_DENIED [2012/10/11 09:55:54.606635, 1] smbd/service.c:678(make_connection_snum) create_connection_server_info failed: NT_STATUS_ACCESS_DENIED How can I resolve this so that I can log in?

• YUM and RPM crash due to the liblua-5.1 library being missing

  - by A troubled linux newbie.

  I've been playing around with a LiveUsb install of basic Fedora with persistence. I attempted to install moonscript, which requires Lua and LuaRocks. After installing Lua and discovering there were flaws in the install which prevented LuaRocks from working, I used rpm to force Lua off so I could use yum to re-install it. The result was an error of this sort being yielded by both rpm and yum: There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: liblua-5.1.so: cannot open shared object file: No such file or directory I've concluded from this that my Lua version installed a library which both yum and rpm are now connected to. Is there anyway to fix this without reformatting my drive and installing everything from scratch?

• Troubleshooting a slow database server with no load

  - by user1721724

  I'm getting ready to soft launch my website and I've run into some problems with what I think is being caused by my MySQL database running on Fedora. All websites run fine, just as I'd expect, but any pages that establish a database connection hang until the connection is established, and then bang, the site loads as it should. Ex. My landing page (http://www.thrusong.com) doesn't make a database connection and loads quickly. User profile pages (http://www.thrusong.com/john) make a database connection and load slowly, even though most of the data comes from memcached and the database currently has no load on it. This problem just came up yesterday when my router died and I began using my Pace 2Wire modem with built-in router. Before, my old router was set to handle everything. My ISP says the settings in the modem are correct. Any ideas? Thanks in advance.

• Is there a way to control two instantiated systemd services as a single unit?

  - by rascalking

  I've got a couple python web services I'm trying to run on a Fedora 15 box. They're being run by paster, and the only difference in starting them is the config file they read. This seems like a good fit for systemd's instantiated services, but I'd like to be able to control them as a single unit. A systemd target that requires both services seems like the way to approach that. Starting the target does start both services, but stopping the target leaves them running. Here's the service file: [Unit] Description=AUI Instance on Port %i After=syslog.target [Service] WorkingDirectory=/usr/local/share/aui ExecStart=/opt/cogo/bin/paster serve --log-file=/var/log/aui/%i deploy-%i.ini Restart=always RestartSec=2 User=aui Group=aui [Install] WantedBy=multi-user.target And here's the target file: [Unit] Description=AUI [email protected] [email protected] After=syslog.target [Install] WantedBy=multi-user.target Is this kind of grouping even possible with systemd?

• How to make local apache server public/visible ?

  - by George

  Hello. I am running an Apache2 server on a Fedora 13. I'd like to make it publicly accessible(visible).For example I'd like when somebody types http://my.ip.numbes/ that they would see what I have in my document root folder. Just for a presentation of a course work at university. Permissions are set to 755. User owning the document root is apache. SELinux is temporarily disabled. But port 80 is closed. I tried to open it by adding an entry to iptables and restarting them, no change. I guess I am missing something big here. Help would be greatly appreciated. Note: I have a static (public, real) IP address.

• Cisco NAC: help with enabling FTP or moving update files

  - by kyoung

  Hi, So this is a LINUX question, and a Cisco NAC question. I'm trying to update our server from 4.1 to 4.7, and i need to move some tarball files to the NAC. the NAC Appliance runs some strange stripped down version of Fedora Core 4 copying the upgrade: The instructions say to FTP the file to the NAC appliance, however whenever i use WinSCP with root credentials, i get a notice informing me the connection was actively refused. I can't for the life of me find any .conf files that sound like winners, so I don't know how to change the settings, however the ftp command does seem to work. what exactly should I do here?

• Additional Hard Drives for Servers

  - by Abs

  Hello all, I am developing a web app where I will have to save lots of files and I am just trying to work out the directory structure and where things should be saved to. I have had a look at the dedicated server I want to buy and for storage it shows this: 2x 1TB SATA in RAID1 The space is enough but I am guessing this will not be on one hard drive? I will have to save files on one hard drive and when that fills up, I have to use the other? For the Fedora distro - what is the path for the second drive? Is there a primary drive where I will be able to setup my webroot? I am sorry, this is all new to me. It would be great to links and advice on how things actually work when it comes to additional hard drives etc. Thanks all

• Moving software RAID to Linux

  - by terman

  I'm using a RAID 1 (mirrored pair) configuration in my Media Center/ NAS system. Currently it's running Windows 8 (yeah, big mistake I know) and I'm regretting it (did it for the games, not worth it). Currently I'm having two software RAID 1s (3TB + 2TB) configured with Storage Spaces and unfortunately formatted with NTFS. Now I would like to switch to Fedora (or maybe Ubuntu if there are advantages) for good. Is there a way that I could continue using the disks as they are without the need to format them with ext or something? I'm glad for every tip. Oh, the system disk is of cause not in a raid configuration.

• Autosaving on emacs or xemacs files (preferably on loss of focus)

  - by Spencer

  Ideally I want to replicate with emacs functionality from TextMate, whereby on loss of focus i.e. I click away from the buffer, my file saves. If this isn't possible, I want to customize emacs so that it will autosave the file for every character I write. When I say this I don't mean I want to autosave to the ~ backup files. I want to save the file I am currently working on. I am working on a Fedora VM. Note I am not looking for a backup or autosave. I want the file I am actually in to save, so that if I loaded the html file I am editing in a web browser it would reflect my new changes without me having to explicitly change it.

• Can I install fresh Linux accross partitions (LUKS & LVM) and preserve/use existing home user?

  - by xtian

  With an existing LUKS encrypted logical volume partitioned hard disk dual boot to Windoz and Linux (Fedora 15), is it necessary to "start over" with the LUKS setup when upgrading the system? I recall some note about dividing the Linux installation over different partitions would help to preserve the home data in future update (I can't find this now) Before I try it, is this possible and intended use case for partitioning a Linux installation? # lsblk -fa NAME FSTYPE LABEL MOUNTPOINT sda [80G] +-sda1 [system W95 FAT 32] vfat +-sda2 ext4 /boot +-sda3 [52.4G] crypto_LUKS +-luks-de25ac97-6a32-4b79-a6a0-296a39376b3b (dm-0) LVM2_member +-cryptVG-root (dm-1) [21.5G] ext4 / +-cryptVG-swap (dm-2) [5.4MB] swap [SWAP] +-cryptVG-data (dm-3) [25.6G] ext4 /home

• Unable to sunchronize local and remote directories ("set times: Operation not permitted")

  - by Tom Auger

  I'm running into FTP errors using software like NetBeans or WinSCP: whenever I attempt to perform a synchronization or update of files from local -- server I get errors on the client saying "set times: Operation not permitted". This is clearly an issue with the way I've configured my Fedora installation. The user that I'm logging in with cannot touch -t any of these files, though he IS part of a group that has r/w access on the files. I do have root / sudo access to this server. What I would like to know is: a) is it likely that this problem would be solved by allowing my FTP user to "touch -t" these files b) how do I enable a certain user to be able to set timestamps on files without giving them ownership of the files (certain of these files need to be owned by Apache, for instance, so I don't want to chown them). Thanks in advance.

• Man pages in Linux

  - by Ayos

  I don't seem to have all the man pages that I need. For example, my college computers (running Fedora 14) have man pages for ASCII, all the standard C libraries (stdlib.h, stdio.h) and so on and so forth. I wish to "install" these pages, after looking up on the Internet I couldn't really find anything that made sense. How can I get, say, the man-page of ASCII (I know it's not really a command or a daemon or anything like that, but typing man ASCII on the college computer gets me a page with the ASCII value table + a little more information). I don't want to keep using the Internet for looking up man pages every time I need to look up a function, function prototype or the ASCII table or something like that.

• Hot-swapping drives

  - by user57770

  I have hot swap drives and controllers, but have never actually used the hot swap capability. What is the procedure for doing so? Do I need to warn Linux that I'm about to pull a drive out? Should I do anything after I put a drive back in? Does it make a difference whether the drive is part of a RAID set? The drives are generally RAIDed, but not always. Any RAID sets are managed by Linux, rather than the controller. The machines are running Fedora and CentOS.

• Linux Permissions

  - by Tres

  I am running Fedora 12 and I've setup a partition separate from my root partition to keep shared files and home directories. Now, I've been having permission issues where it says the user cannot chdir into their home directory (/files/home/*). Now, I fixed this originally by chmodding / to 0755 and the home directories also to 0755. And yes, the user is the owner:group of their home directory. Now get this, I didn't change a thing, rebooted, everything still works. Great, right? I boot the server up a day later, and now same ol issue. This is a home server that wasn't on at all at any point in between the working state and non-working state. Also, nothing else was modified. Any ideas? Thanks!
