More info for -perm 2 ?
by Fajar Priyanto 15 Apr '08

15 Apr '08

Hi all, Is there any more exhaustive explanation on this command? find / -type f -perm -2. Someone said that it means to find all files which have 'other' write access. From the man page it only says: -perm mode File’s permission bits are exactly mode (octal or symbolic). Symbolic modes use mode 0 as a point of departure. -perm -mode All of the permission bits mode are set for the file. -perm +mode Any of the permission bits mode are set for the file. Is there any table that explain all that mode? Thank you. -- Fajar Priyanto | Reg'd Linux User #327841 | Linux tutorial http://linux2.arinet.org 07:49:46 up 37 min, 2.6.22-14-generic GNU/Linux Let's use OpenOffice. http://www.openoffice.org The real challenge of teaching is getting your students motivated to learn.

GNOME issue. Seeking Guidance.
by Christy.New＠cancer.org 15 Apr '08

15 Apr '08

Below is what has been documented on this issue, and I am needing further guidance. Essetially, I am running in GNOME, but it isn't working properly. Can some one help. |----------------------------------------------------------------------------------------------------------------------| |I am new to the Centos ISO and was looking for a forum, when I came across this. If it isn't something you can help, | |can you help point me in the right direction? Here are the answers you requested from me: | | | |I go to the applications menu at the top left and click to pull down | |I click on Add/Remove Software but nothing happens. | | | |I am using GNOME | | | |I go to the system menu at the top left and click to pull down, and then click admin and then click network. Nothing | |happens. | | | |It is like the GNOME is not working properly. It did work until I pulled down the software updates after the initial | |intstallation. | | | |Again, thank you. | |----------------------------------------------------------------------------------------------------------------------| |----------------------------------------------------------------------------------------------------------------------| |There are several ways to get help with CentOS: | | | |The CentOS web forums are at http://www.centos.org/modules/newbb/ [^] | |The CentOS email lists are at http://lists.centos.org/mailman/listinfo/centos [^] | |Realtime forums (IRC) can be found via http://www.centos.org/modules/tinycontent/index.php?id=8 [^] | | | |In your case, I am expecting that the pirut or system-helper command are not working correctly. Please try the | |following. | | | |Right click on the desktop and choose "Open Terminal". In the terminal type pirut. A popup window should occur asking | |for the root password. If it doesnt, then there is a permission problem that might have 'broken' during an update. | | | |In the terminal type "ls -l /usr/bin/pirut". And you should get output like the following: | | | |[smooge@canopus ~]$ ls -l /usr/bin/pirut | |lrwxrwxrwx 1 root root 13 Apr 12 2007 /usr/bin/pirut -> consolehelper* | | | |[smooge@canopus ~]$ ls -l /usr/bin/consolehelper | |-rwxr-xr-x 1 root root 5920 Mar 14 2007 /usr/bin/consolehelper* | | | | | |If it is a permission problem, we can try the following: | | | |1) Login as root (in the terminal window you can do a "su - root" | |2) Type the following: | |/sbin/restorecon -R -v /etc /usr /sbin /bin /var | | | |This will take a long time, but it should restore selinux permissions to some items that either zenoss or an update | |accidently "broke" | | | |After this command finishes try the following: | |Top Menu -> Applications -> Add/Remove Software | | | |If it pops up now.. then it was an selinux item. If it does not then there is a problem with consolehelper talking | |getting root which might have occured with the zenoss install. I would first check with them to see if it is a known | |issue on their part, and then with the forums. | | | |/usr/bin/consolehelper is a program that allows a normal user to get super-user/administrator rights. So there are 2 | |pirut programs. /usr/bin/pirut calls consolehelper which calls some programs to make sure you can become 'root' If you| |know the root password then it will call /usr/sbin/pirut which is the real program, but only runs as 'root' not a | |normal user. | |----------------------------------------------------------------------------------------------------------------------| |-------------------------------------------------------------------------------------------------------------------| |Yes and no luck yet. I have contacted Zenoss, however they seem to think it is with Centos. Since it is a free | |utility, they are very reluctant to offer support. If I were to pay, then they would graciously put for the effort | |to help. So I am on my own. I don't mind the CLI, actually I prefer it, but my co-workers are were I am concerned. | |I want them to be able to use it, and be comfortable with it. But with out being able to use the GNOME (GUI). They | |are reluctant to do so. That is my fear. They know nothing about Linux or UNIX, and only know router's and switches| |CLI. If you can offer any guidance, I graciously welcome it all | |-------------------------------------------------------------------------------------------------------------------| |-------------------------------------------------------------------------------------------------------------------| |When I open a terminal, there was no issue. When I typed int ls -l /usr/bin/pirut, I got just as smooge said I | |would, lrwxrwxrwx 1 root root 13 Apr 12 2007 /usr/bin/pirut -> consolehelper*. Then I typed in ls -l | |/usr/bin/consolehelper, I got -rwxr-xr-x 1 root root 5920 Mar 14 2007 /usr/bin/consolehelper*, again just as smooge| |said I would. He then asked that I log in as root, which I was already at. When I typed,/sbin/restorecon -R -v /etc| |/usr /sbin /bin /var. There was something different, than what Smooge said it would do. It was either instance, or | |it appeared like nothing happen. He had mention that it would take it a while, and it appeared to do nothing. So | |once I did all he asked, I stillcould not open the add/remove, or the networking information up. I also tried to | |reboot the server, to see if maybe the changes would take effect then, and no success. Thanks for the help. | |-------------------------------------------------------------------------------------------------------------------| |-------------------------------------------------------------------------------------------------------------------| |When I run pirut from root it tells me: "Unable to import modules. Maybe you're not running under X?". When I log | |under another user, and run the command "pirut", it prompts me for the root password, and then tells me the same | |thing. | |-------------------------------------------------------------------------------------------------------------------| |---------------------------------------------------------------------------------------------------------------| |Are you running under some sort of GUI? GNOME, KDE, XFCE, whatever - meaning are you running under a graphical | |environment? | |---------------------------------------------------------------------------------------------------------------| |-----| |Yes | |-----| Please Advise.

redirecting outside connections to https on apache
by ankush grover 14 Apr '08

14 Apr '08

Hi friends, There are about 15 applications hosted on different in our infrastructure mostly running on apache/iis/tomcat. We have a frontend apache server running on Centos 4.4 64bit which make these applications accessible to outside world. For the applications which are running on tomcat we are running jkmount to make these applications available without mentioning tomcat ports. For apache/iis applications we are using ProxyPass. The issue we are facing is that we are not able to make these applications accessible through https automatically means if the user is not from within the LAN then the http link should automatically redirected to https. We already have GoDaddy stamped ssl certificate on this apache frontend server but we are struggling for rules for outside world. What is the best way to make these applications accessible to outside world through https connections only that is if somebody use http://xx.xx.com/xx to use the application it should be redirected to https we don't have the requirement for https connections from within the LAN but definitely for outside connections. JkMount /team/* team JkMount /team team Then we have rules for this in the workers.properties file ProxyPass /public http://my.testing.com/public ProxyPassReverse /public https://my.testing.com/public Please let me know do you need any further inputs Thanks & Regards Ankush

MS Exchange to CentOs (multiuser)
by Frank M. Ramaekers 14 Apr '08

14 Apr '08

Is there a way to get mail from a MS Exchange server that is addressed as user(a)host.domain.com rather than the user(a)domain.com so that users on host.domain.com can read their mail on that host (CentOS). (I'm assuming that Exchange needs to know about host.domain.com, somehow.) Frank M. Ramaekers Jr. Systems Programmer MCP, MCP+I, MCSE & RHCE American Income Life Insurance Co.

Custom SELinux file contexts?
by Ingemar Nilsson 14 Apr '08

14 Apr '08

Hi. Do anyone know of some place to put custom SELinux file context specifications? I would prefer not to append lines to /etc/selinux/targeted/contexts/files/file_contexts but rather put one or more similar files somewhere. A file_contexts.d firectory would be nice, but it isn't available. Just creating your own file_contexts.local file does not work, I already tried. I'm running CentOS 5.1 Regards Ingemar

Re: [CentOS] merge an lvm snapshot back
by Ross S. W. Walker 14 Apr '08

This and dump/restore should work. Make sure the amount free in the snapshot is greater then the amount used though because it will double the snapshot usage. -Ross ----- Original Message ----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Mon Apr 14 00:23:21 2008 Subject: Re: [CentOS] merge an lvm snapshot back On Sun, Apr 13, 2008 at 07:59:20PM -0600, Joseph L.
