Server :: Set PATH For All The Users Permanently On Fedora 8?
Apr 15, 2011
I am failing to set PATH for all the users on a linux box(Fedora 8), permanently. Basically, I have installed two different versions of python(2.5 & 2.7) Python2.5 path is /usr/bin and it is set by default for all users(not by me, also i don't know how ) and it is working fine.
Python2.7 path is /usr/bin/Python27/bin, so tried this:
PATH=$PATH:/usr/bin/Python27/bin
And it worked only for that particular session and for only root, as I set path from root user. So, i need this to be set for all the users on the linux box, including root, more importantly as permanent. So if any user types "python27" at the command prompt, it should give python2.7 prompt.

I have added the smbd file location to the path of root. I can now execute it from any location. I noticed after reboot of the machine (RHEL 5) that this file location is no longer in the path. How do I make this permanent?

1- I open terminal window.
2- I write following commands :
export GOROOT=/home/linux/go/hg

I'm working on my first .deb package. I need to add the /usr/sbin directory to $PATH for root. I think the easiest way to accomplish this is to add a little code to the postinst file.

What steps have to be followed for having customized contents of PATH environment variable whenever new users are created? I require this in order to include a special directory into PATH variable; and this has to be a default one for all the newly created users.

I am trying to set my java path so that it is in effect for all users including the root user. I set the path correctly in /etc/profile and that works for my personal user, but when i try to run the same commands using sudo, i get messages saying that it can't find the java path.

I've installed rubygems on ubuntu, but it has a known issue that the rubygems' bin/ directory is not in the PATH. I know about exporting the PATH variable, and adding it to .bashrc, but I'd like to configure it so that every user has it on his PATH, even if he tries to run it with sudo. Where should I export the PATH variable then?

When I add some path in .bashrc by commenting out old path and adding new one like this:
#EXPORT HOME_PLAY=/home/gem/old_play
EXPORT HOME_PLAY=/home/gem/play
EXPORT PATH=$PATH:HOME_PLAY
After saving above changes, I enter the command: source ~/.bashrc Now if I do echo $PATH, the path shows both the old PLAY_HOME and new PLAY_HOME. This is really bad and messes up a lot of things in my project. This problem only goes away if I logout or reboot, a rather very long process. What is happening is that the old path is added to new path element and the old path includes the old path element you want to remove.

Now i want to disable my ssh server "permanently",which means it won't run unless i start it after i login.that is,it is disabled at boot time by default.
i have asked a similar question before,but i still have some confusions.
Say that now the ssh server is running.my system is ubuntu 10.04. code...
The disable|enable API is not stable and might change in the future.
the shell gives me a warning:do not match LSB Default-Start values,this API is not stable and ...
what does this mean? still it can't disable the server "permanently",ethier.
what on earth should i do to solve this?

running Windows 7 64bit with VMware Workstation 7.01-build 227600. I have some knowledge of Linux, I have installed f12 and have updated the system as of 03/22/2010. All updates completed successfully.
1) How do I install VMTools on the f12 (after mounting the CD/DVD tool package)
2) How do I update the gcc files it says are dependencies?
Here's what I get on installation:Before you can compile modules, you need to have the following installed...
make
gcc
kernel headers of the running kernel
and then I am prompted for this input from the install script:
Searching for GCC...
The path "" is not valid path to the gcc binary.
Would you like to change it? [yes]
and this is where I get stuck. How do I get around this or satisfy the requirements for the install?

I got this problem where my USB ports don't work. So if I do the command:
modprobe -r ehci_hcd
it fixes it. I can put it in the /etc/rc.local so that it runs every time when the server reboots. But, I want the ehci module removed without ever being loaded because sometimes the server goes through an fsck and the module is loaded and therefore I cannot use my IPMI to access the server.
I believe that my kernel has it within it because blacklisting the module does not work. I've tried remaking the initrd with this:
add module to /etc/modprobe.d/blacklist
mkinitrd -f /boot/initrd-$(uname-r).img $(uname -r)
and that didn't work. I've searched on how to do it but nothing is really clear. I would like to know what the command would be to do this. I use Fedora 8.
I would like the ehci_hcd module to not be loaded so that if the server goes through an fsck, the module is still not loaded.

I was following the above guide to get a mail server up and running. The major difference in it all is the fact that my server is running i686, but I compensated for that easily, just a difference in folder/RPM names. [URL]. Otherwise I followed it to a "T." Everything seemed to go smoothly, no trips or falls until the very end.
After installing squirrelmail and trying to login on admin@withfrosted.com returns ERROR:
Connection dropped by IMAP server.
Uncle google tells me to run this command because SELinux is overzealous:
setsebool -P httpd_can_network_connect=1
And that works, and I thought I was home free. However, after that, I'm presented with a new error. However, google told me to send an email to create the mailbox because it wasn't there, yet. So I send a test email on over, but that fails, and so does mailx. Next I created /home/vmail/withfrosted.com/admin while logged into the vmail user for proper permissions. Squirrelmail now logs into the mail box but gives me yet another new error, in which I am now stuck on:
ERROR:
ERROR: Could not complete request.
Query: SELECT "INBOX"
Reason Given: Unable to open this mailbox.
As a summary, because I'm all over the place, here:
1. Can't view the mailbox via Squirrelmail.
2. Can't receive email, tried with mailx and a test email from gmail.
Regarding #2, the gmail test email, from the maillog:

I run my own home server using OpenSuse 11.1, everything is setup using apache, php, etc etc, and it all works perfect, but now I need to use my own email server for the use of Dolphin social networking software, so that when someone registers, the email server sends out registration confirmation emails, so I set up postfix, yeah right!!!, even though I followed all instructions to set postfix as a closed relay, a test done at mxtoolbox site still said it was an open relay, but while I was trying to set up postfix, my access to the server slowed down, and my servers drive light was constantly active,,, so when I look at the mail queue, I saw 4000+ emails, all from japan, (hinen.net), so I promptly shut down postfix and use postsuper -d ALL in the command console to delete the queue, but no matter how I try, I couldn't configure postfix as a closed relay,,, so I uninstalled it and installed sendmail, and using webmin, I could use a spam list and block the domain, now, sendmail's test at mxtools show as a closed relay, I can't even send out a test email using smtp auth, but disabling auth, I can, but now my IP is blocked at spam cop, and spamhaus,,, gmail server say my IP is not authorized to send to their servers, but to use my ISP relay instead,,, but my ISP doesn't have a relay,,hence the need to run my own email server.
My home server uses double layer firewall, a hardware firewall between the internet and the server, and a software firewall on the server, and I only allow the ports I need, IE, 80 = http, 443 = https, 20/21 = ftp, 25 = smtp, 110 = pop3. and that's all, but any other internal access from my workstation to the server, using ssh, I only open the ports on the server firewall. If someone here has a great deal of knowledge on sendmail, and can set up a an M4 (linux.mc) config file for me, it would be much appreciated. What I would like my email server to do, is to only allow the sending of emails from inside it's own server system,, ie, when a php script sends an email to the server, then the email server would let it through, but anything else, outside the local network is ignored.

Newbie here! Our website CMS is a Tomcat webapp, which runs on a CentOS 5.6 release (Final). The webapp needs a permanent increase of the max. open files value. Currently, the site is "crashing" frequently due to continuous "Too many open files" exceptions that eventually will occur when traffic increases.
This is what I've done to try to increase the max. open files value code...
But still, when I log in (as any user, incl. root), ulimit -n shows 1024, not 16384. Am I missing something here? And, more importantly; Will Tomcat be able to open > 1024 files after my changes mentioned above?
(PS: I also tried rebooting, but no difference.)

Samba up and running on my pc. pc runs FC12 with kde. A laptop has win vista. The pc can access the shares on the laptop but the laptop has authentication issues to access the pc. Note that windows doesnt enforce authentication forincoming network connections.Using the system-config-samba util i tried to map a windows user to the unix user "feduser". The laptop (named LAPPY) has a user (lapuser) which has on windows no password.What should I tell samba config what the windows username should be? lapuser or LAPPYlapuser doesnt work because when accessing the pc via the laptop, the authentication fails. The only auth that is successful is when choosing the same winusername as the unix username.
Secondary, id like to setup the laptop so that the user doesnt have to provide a name and password, or at least not more then once in the lifetime of the laptop. Note that you cant provide an empty password to system-config-samba. How is that possible?
Strange but not really on issue imho:the samba - KDE control module(kcmshall4) (and the smb.conf) shows 2 shares: the homedirs and the data dir the samba server configurator (system-config-samba) shows only the datadir.

I have inherited a RedHat 5.4 server that is having an odd issue. Root and all of the user accounts can log in via SSH. Not a single account can log in via the console (sitting in front of the server). If I bring it up in single user made, I can log in with root all day long.
I want to say that this has something to do with PAM, but this is when I play my "Noob" card. Could anyone possibly steer me in the right direction to figure out what is going on?

I came across the following method of how to permanently disabling selinux and it's notifications. Although changing enforcement from the gui into permissive mode does most of the job, the notifications still pop-up when some applications are started.
So to disable it do the following:
open terminal as root and execute:
Quote:
And then change the SELINUX line to SELINUX=disabled
Quote:
This is it. Now reboot the system and selinux will never bother you again.
If you are not a Fedora user and you are using this forum just because we are cooler here then you will not find the /etc/selinux/config as in the fedora releases. What you need to do is to edit the kernel boot line and add selinux=0 at the end:

Reboot the system
