Fedora Servers :: Rsync And SELinux: Software Not Working?
Feb 19, 2009
I am using FC 10. I did an rsync to get a software Matlab from the local lan. But Matlab does not work. The error is:
Quote:
License checkout failed.
License Manager Error -96
MATLAB is unable to connect to the license server.
[code]....
I have set SELinux as Permissive for the current enforcing mode, while the default enforcing mode is Enforced. I did rsync in this way:
Code:
rsync mecsmrao@10.16.4.32:/home/pkg/lic/matlab-7.6/ /usr/local/pkgs/matlab_7.6_r2008a/ -avtpog -e ssh
What am i supposed to do?

You can find a list of all the booleans for SELinux (Fedora 10) using getsebool -a My question is, is there a reference online that describes each one. Most of obvious but it's one of those "I have to know because it's there situation).

I recently had three problems with SELinux: httpd_unify - SELinux prevented my web server from having write access. ftp_home_dir - SELinux prevented my virtual users from connecting to their home directory. textrel_shlib_t - SELinux prevented two separate Unreal Tournament 2.5 mods from running. The troubleshooter did not notify me of any of these problems. I finally figured out how to fix them on my own and did. CentOS had a very concise, albeit excessive SELinux troubleshooter that involved notifying you of every single problem on your server multiple times. Still, I would rather be spammed with notifications than receive none at all.
If I had not switched from a CentOS box, I would not know the chcon command to set textrel_shlib_t to my mods, as I cannot do it in the SELinux Administration without making it global. How do I fix the troubleshooter to report?

Thought I'd post it here because it's more server related than desktop... I have a script that does:
[Code]....
This is used to sync my local development snapshot with the live web server. There has to be a more compact way of doing this? Can I combine some of the rsyncs? Can I make the rsync set or keep the user and group affiliations? Can I exclude .* yet include .htaccess?

I am in a class called Linux System Administration and we are setting up Fedora 8 as a server. Per the class instructions, I have changed the default runlevel to 3 so the system always boots to a command line. The instructions say log in with your regular user account [I KNOW HOW TO DO THIS] and use the startx command to load GNOME. [I HAVE NO IDEA HOW TO DO THIS]
I searched the Internet and the text book, but found nothing I could understand.

I don't think it has anything to do with the config file. More to do with SElinux. I need to know how to configure SElinux so I can see my samba share when SELinux is on. When I setenforce 0 I can seen all the files and folders set it to setenforce 1 cannot see anything.
Here is the output when I ran [root@fileserver /]# getsebool -a | grep smb
allow_smbd_anon_write --> on
smbd_disable_trans --> on
These two options were off I tried turning them on.
This is another one of the commands I tried running. I did change a few options but I am not sure which I do need to change. I am running a stand alone server so I don't need the DC option.
[root@fileserver /]# getsebool -a | grep samba
samba_domain_controller --> off
samba_enable_home_dirs --> off
samba_export_all_ro --> on
samba_export_all_rw --> off
samba_share_nfs --> off
use_samba_home_dirs --> on
I can also post a copy of my smb.conf file too.

I setup an rsync in cron to sync a master server with a backup server. however not everything gets copied over or removed. I believe this to be a permissions issue on the backup server. I am using a user we created specifically for this, and the rsync is setup to preserve permissions and delete files that have been deleted on the master..
Here is the rsync command:
59 11,23 * * * rsync -avP --delete -e "ssh -pPort" /media/_Files user@ip address:/media >> /home/user/sync.log
Of course the ip address, user and port number is something else then above.. Is there a way to make the user that is initiating the sync into a superuser like root? That way everything on the backup server can be updated as necessary? I don't want to use root, Id like it to be a name I can keep relatively confidential.

I have installed Fedora Core 11 with SELinux enforcing.It appears (via log files) that if I use a .forward file in the home directory for root that SELinux prevents the use of this mechanism for forwarding e-mail.Is there a way to continue to use SELinux and be able to forward root's e-mail to an outside account?

I receive the message "SELinux is preventing /usr/sbin/vsftpd "net_raw" access" many times. Found this bug at redhat but really do not understand what i should do about it ((( Kindly let me know how to change this to normal. Shut down Selinux is not the way out.

When I try to login as a user, I get the dreaded "500 OOPS: cannot change directory:". Almost every posting I can find related to this problem was due to SELinux being enabled. My SELinux is operating in permissive mode. So why can't it open the home directory when I log in as the tarheelnk user?
Code:
[root@server1 home]# ls /home/ -l
total 36
-rw------- 1 root apache 7168 2009-09-11 16:24 aquota.group
-rw------- 1 root apache 7168 2009-09-11 16:30 aquota.user
drwx------ 2 root root 16384 2009-09-11 10:07 lost+found
drwsrws--- 4 tarheelnk apache 4096 2009-09-11 14:58 tarheelnk

I've been trying to get SELinux working in OpenSUSE 11.2. So far I can get to runlevel 3 with enforcing=0. Before I start tinkering with audit2allow, The 11.2 repository gives me these policy rpms:
[URL]
But that version of policy has some issues in OpenSUSE:
1) failure to allow the graphical desktop to load (even with enforcing=0) . The following message appears in the console during boot:
** (gdm:1073): WARNING **: Couldn't connect to system bus: A SELinux policy prevents this sender from sending this message to this recipient (rejected message had sender "(unset)" interface "org.freedesktop.DBus" member "Hello" erro name "(unset)" destination "org.freedesktop.DBus") startproc: exit status of parent of /usr/sbin/gdm: 1 Since enforcing is off, I'm surprised to see a message like that. SELinux shouldn't be preventing anything, so I don't see how modifying policy will solve that. Ideas?
2) Attempting to boot to runlevel 5 with kernel parms "security=selinux selinux=1 enforcing=0", I'm dropped off in runlevel 3 instead. I'm getting a couple of pages of AVC errors after boot (see below). I've tried several other versions of the policy without luck:
- the version included in Fedora 12 (refpolicy-2.2009117
- the latest release from Tresys
- the latest from the repository at Tresys

I have two servers. #1 is the main server and #2 is only used in case the first one is down. Both of them are in the same LAN. Both are debian Lenny configured the same way. For instance, if #1 has a problem, I simply disconnect it, set #1's IPs to #2 and I have my system ready. The only matter here is that there are plenty of files that need to be syncronized between #1 and #2. I thought that rsync was the answer to this problem I have.
I wanted to create a bash script that runs every day (with cron) and syncs the files I need (.conf, and other data). I used ssh-keygen to generate a pair of keys in order to login SSH without a password. The problem is that the permitRootLogin is set to yes in my sshd_config in both servers. So I can't log in directly as root by ssh. But I need to log in as root to be able to rsync the files between the servers because some of them are .conf files and aren't accesible for non-privilege users (Only root).

I am running a headless Ubuntu server accessed through Webmin. The server is running 10.4.2 64 bit version. I have a number of cron jobs including a simple back-up job which is:
Code:
rsync -av /media/server/ /media/backup/backup/
All of the other jobs run fine but for some reason this job which is scheduled to run each day at midnight does not run. If I SSH into the server and run the job manually it works fine.
The output of 'crontab -l' is:
@daily rsync -av /media/server/ /media/backup/backup/
11 3 * * * /etc/webmin/package-updates/update.pl
@daily tar czf /media/backup/serversystem.bz2 --exclude=/proc --exclude=/lost+found --exclude=/backup.tar.bz2 --exclude=/mnt --exclude=/media --exclude=/sys /
@reboot inadyn --username ********** --password ********** --update_period_sec 600 --alias **********
@daily /etc/webmin/backup-config/backup.pl 12978522112842
The output of 'crontab -e' is:
Error opening terminal: unknown.
crontab: "/usr/bin/sensible-editor" exited with status 1

I've 15 web servers (in private network) running RHEL, Apache. Needs to sync web files between them. each server is accessible to each other via public key (with passphares).
1) Main server is web1 (where dev upload files initially). So I can make all other servers accessible by web1 without password/passphares and run rsync periodically to update files between them. But security is an issue here as all servers will become easily accessible.
2) Run rsync daemon in all other servers (except web1) on designated port and run rsync command from web1 to sync files. This will do the work but running daemon in all servers might increase overhead and making sure that daemon is running all the time etc. are my concern for this implementation.

I would like to use rsync to keep the hard drive in my media server synced with my video collection on my linux server. The media server I believe is running some version of linux running samba. I mount the media servers share to a folder on my linux server & use the following command: rsync -a -vv --delete /home/shared/Videos/* /mnt/WDLive/Shearer Files/Movies/
However, it does not delete files on the media server that I delete on the source. I also created a new folder on the source & moved some of the files into it. When I ran rsync again, it created the new folder on the media server, but it recopied all the files from the source again, instead of moving the files which were already on the media server into the new folder, so no I have 2 copies.

I am trying to remove old / deleted files on the destination server that have been removed from the source server. I am running this command on the source server and don't see any files being deleted at all. I know for a fact that there are old / obsolete files on the destination server (10.1.10.222) that can be removed. Is my command syntax not correct?
Code:
[root@source_srv /]# rsync -zave ssh --delete-after root@10.1.1.223:/home /home/
root@10.1.1.223's password:

We are looking to centralize some code in a scalable environment. So some servers may do other jobs, etc. doing other things, but the key element is when the server is booted, I want it to rsync some config files, scripts, etc. local to the box and I am having an issue as things are a bit different from an RHE server.
I have a test entry in the rc.local a simple touch testfile, then after that a restore.sh file. I reboot the box, wait a minute then login. I see hte testfile timestamp updated yet the rsync doesn't fire. I can then manually run it and it works fine, but I need to have this go on boot.

I have a Linux host acting as an ISCSI server for a Windows box. I want to keep an off site backup, so I figure rsync will keep the ISCSI server synced with an offsite Linux host. I understand that Rsync does block level incremental transfer to conserve bandwidth ok, awesome.The trick is, that I also want an archival copy kept. Say I want to go back to a revision of a file from 10 days ago, I need to be able to do that.
I was planning on using Backup Exec, since we currently have a licensed copy. Throw the archives from Backup Exec onto the ISCSI server as well, and have it keep a rotating 30 day backup, or something like that. The issue I see here is that this will be creating a deleting files as it does its daily backup rotation. I'm guessing RSYNC will see these as new files, and likely retransmit everything on a daily basis. The question then becomes, is this assumption correct, or will it still know to do a block level incremental transfer even when file names and such are changing?

I support a small business which has an Ubuntu server running as a file server. The server is running Ubuntu 10.4. There is one hard drive which is mounted as /media/hdd. Each night this is backed up to an external USB hard drive mounted as /media/backup. The backup is carried out using the command:
Code:
rsync -av /media/hdd/ /media/backup/
Is there a way to encrypt this back-up so that if the USB hard drive is plugged into another machine it cannot be read?

I made a shell backup script that uses Rsync and I am trying to get rid of the password prompt because it will use a CRON to run. I have set my variable in my shell script at:
PASSWORD_FILE=rsync_password
And the password in that file only takes up 1 line.
However when I run (ignore $DESTINATION)
rsync -aRvz tmp $DESTINATION --password-file=$PASSWORD_FILE
It still gives me the prompt. How can I accomplish this? I cannot allow a prompt and I do not want to have to use keys.

I have a pc that i have upgraded Ubuntu from version 9.10 to 10.04 to 10.10. Now, in Maverick I can not get rsync to work correctly. The delete option does not work and updated files in the source do not get recreated in the destination. Can someone tell me if I'm doing something wrong:
My rsync command and output:

I have a cron job that runs overnight for a rsync script that backups my home directory to a external hard disk that is connected to the computer via usb 2.0. I also output the results to a log and follow it via tail -f command from a terminal, to monitor it.
Here is the script:
Code:
#!/bin/bash
# backup data on a daily basis via rsync and a cron job
echo
echo backup started `date` >>/home/user/scripts/backup/backuplog
echo
rsync -avh /home/user/ /media/Linux_ext3/
echo
echo backup complete `date` >>/home/user/scripts/backup/backuplog
echo
echo disk used: `du -csh /media/Linux_ext3` >>/home/user/scripts/backup/backuplog
echo
echo disk free: `df -h /media/Linux_ext3` >>/home/user/scripts/backup/backuplog
echo
Two things
- The rsync is doing a complete mirror of my home directory to the usb drive. For example, say I have a .txt file at the root of /home/user. It gets copied over. However I delete the .txt file the next day and if I go to /media/Linux_ext3/, the .txt file is still there.
I was always under the impression that rsync would mirror the two directories, correct?
-For my log, I think it is creating an entry, I think, for each file. Again, was under the impression that rsync would only copy over files that have be updated, correct?

I'm going to make a nightly backup copy from one server to another, using rsync. If I have a sufficiently large file, say 4+ GB or so, I'm not interested in copying the whole file if only a small change has been made. Can rsync detect small changes on block level and backup only those if needed?

I have several copies of a file set with different organizational structures, but the same files. i.e.
On client1 files can be found in ~foobarfile1, ~foobarfile2, ~foo-avernfile3, ~foo avernfile4
On client2 files can be found in ~foo-barfile1, ~foo-barfile2, ~foo-tavernfile5, ~foo avernfile6
On client3 files can be found in ~file1, ~file3, ~file5, ~file7
I have access to one client and the server where I'd like all the files to be synced. I'm not worried about conflicts, just having a complete copy of all files[1-7]. Is there a way to cause RSYNC to remove the directory structure, so that I get something like:
client1% rsync files server:backup
client2% rsync files server:backup
etc
where at the destination all files will be checked against the destination set regardless of the source directory structure?

I installed cygwin with rsync on a Win XP Machine. My goal is to backup a folder from one hard drive to another (both on XP machine).
I run the following command from a batch file:
Works fine except the --delete flag is not working. Copies everything in source to destination, but doesn't delete some extra files that are present on the destination, but aren't on the source, which it's supposed to. I looked at the rsync man page, and I'm doing everything right... such as not using wildcard.
The same command works perfect on another computer (XP machine; source and dest both on XP machine).

I've just noticed a small problem I am having with my company file server. When making backups to an external NTFS drive weekly I have noticed that the file names with thai characters are not getting backed up. I receive the below error:
rsync: recv_generator: failed to stat (to the file name...)
Invalid or incomplete multibyte or wide character (84)
There are thousands of files on the server that contain thai characters in there names so how do I get around this problem so it will back up all files and not just the English character ones. I read somewhere that each file would need to be converted to a different character set but this would take years as there are so many files.
