Server :: How To Reset Root Password For Redhat Machine
Oct 25, 2010Yesterday, when I was installing Redhat Enterprise 5.4 on a HP server, I asked myself "how can I regain my access to the server if I happen to forget the root password?" I knew there must be a way. I consulted with my friend "Google". I'd like to share it here as my 1st post (too bad that I'm not allowed to paste screenshots)
1) Boot up the server, when you are at the "Red Hat Enterprise Linux Server..." entry, press "e".
2) Highlight the "kernel /vmlinuz...." line then press "e" again.
3) Type the word "single" to the end of the line (with an empty space before the word single). Press Enter.
4) Press "b"
5) System will boot. When you get the prompt "#", type "passwd" to enter in new password for root.
6) Reboot the system. Done

View 3 Replies View RelatedServer :: Network Disk Mirroring Of >16TB XFS Volumes?
Jul 29, 2011I'm setting up two media servers - one will be primary and the second will be the failover box if the first one dies. My original plan was to use Heartbeat and DRBD to replicate the first to the second, but it turns out DRBD has a limitation of 16TB per volume, and my RAID 6 is 30TB in size. I'm trying to figure out some options.
One is to split the partition into two, so it's under the 16TB limit of DRBD, share both partitions, and then use LVM to join them as a single volume at the OS level. I'm not sure what kind of performance hit that will make on read/write access since now it will need to go through LVM *and* DRBD.
Two is to use something like GlusterFS or XtreemFS. However, I am wary of both of those as the first is a FUSE-based system and isn't really tuned for performance, and XtreemFS is still kind of beta-ish.
Three is good old rsync, but that is a bit too asynchronous in my opinion. I'd like to be able to fail over virtually instantly and not lose any content.This is a production system and performance of the disk systems are paramount, followed by reliability.
Server :: Simple Mirroring Networked File System?
Apr 8, 2010I have two web servers. One is active and one is in reserve. I keep the user data (web pages) in sync by running rsync every 10 minutes or so. This copies any changes from the active machine to the reserve machine. But, it's slow, only gets changes every 10 minutes, bogs down the disk, does strange things to files that are changing during the rsync process etc...
I want something that will automatically copy any changes from the active server to the reserve server as they are made. IE I hit 'save' on the active server, it copies the file to the reserve server. Simple!
I've been looking around and I see GFS which is really vastly more complicated than I need. I'm happy with read-only access on the reserve host, so I don't need distributed lock management.
I could theoretically implement this by setting inotify watchers on every file and running an SCP or rsync command when a file gets saved. So, it can't be that hard.
I do not need a true networked file system, as in something I mount over the network. I just want something to keep my disks in sync.
Server :: Unioning And Mirroring File System Over The Internet?
Apr 6, 2010Blue sky thinking at the moment:I have a number of file servers, each at different sites. I would like to be able to make these appear as one, so that files on any server can be accessed from any site, and the user doesn't even see there are multiple servers.Obviously, the internet is slow, especially the upload speeds. So when a file is written the write ought to go to the server on the client's LAN - even if it was previously on another of the servers.However, for robustness, some sort of background mirroring is also wanted. If all the servers were left on and connected, they eventually end up all in sync. But this mirroring needs to be mindful of bandwidth usage; if someone writes a big file to their local server, copying that to the other servers can't interfere with normal internet usage.I think UnionFS or similar might be able to handle the unioning side, but not the mirroring stuff.

May 16, 2011In Redhat 4.x, we can use 'smbmount' to mount another linux samba server with 'user1'. But now we used redhat 5.3(64bit), there is no smbmount and I can only user mount command via root.
How can I mount a folder via 'user1', not root?
(BTW, I can run '#mount hostname:/sharename /mnt/u1, but the access right of /mnt/u1 is only for root.)
$ls -la
drwxrwxr-x root:root 4096 May 18 2010 u1
I wish it is "user1:user1"
drwxrwxr-x user1:user1 4096 May 18 2010 u1
I also edit /etc/fstab and add the following in. hostname:/sharename /mnt/u1 noauto,user1 0 0
mount: only root can mount xxx on xxx. It still doesn't work.

View 1 Replies View RelatedServer :: Rsync Files And Directories From A RedHat Host To A Windows Server 2003R2?
Jun 9, 2011I'm trying to rsync files and directories from a RedHat linux host(v 4.5 & 4.7) to a Windows server 2003R2 Standard Edition with cygwin running. I'm executing the rsync command from the cygwin shell. The transfer involves rsync'ing approximately 1 TB of data from the linux server to the windows server. After about 280+GB of data transfer, the transfer just dies.
There seems to be no particular file or directory that the transfer stops at. I'm able to rsync GB's of data from other linux hosts to this cygwin server with no problem. Files and directories rsync fine.The network infrastructure is essentially the same regardless of the server being rsync'ed in that it is GB Ethernet running through Cisco GB switches. There appear to be no glitches or hiccups across the network path.
I've asked the folks at rsync.samba.org if they know of any problems or issues. Their response has been neutral in that if the version of rsync that cygwin has ported is within standards then there is no rsync reason this problem should happen.I've asked the cygwin support site if they know of any issues and they have yet to reply. So, my question is whether the version of rsync that is ported to cygwin is standard. If so, is there any reason cygwin & rsync keep failing like this?
I've asked the local rsync on linux guru's and they can't see any reason this should fail from a linux perspective. Apparently I am our company cygwin knowledge base by default.

Server :: Fedora Sending Mails From Root With Non-root Account?
Jul 14, 2011I've started to get emails that would typically come from [URL] as [URL]. These emails come from services that send out emails (backup programs) directly, or from cronjobs. I've logged in as the non-root account and either sudo su - or su - to root and the restart the service at one point or another. If I login directly as root and bounce the service or cron the emails come across as from root. I don't see anything in my environment variables after I su to indicate what would cause this. I'm not sure where else to look? A pam setting? This seems to have happened between Fedora 10 and 14 (did a bunch of overdue upgrades recently) I've only got Fedora so I don't have anything to compare to. In Fedora 10 I did not have this problem.

Server :: CVS Configuration On Redhat Enterprise ?
May 11, 2009Installation of CVS on Redhat linux
Installing CVS on Redhat Linux Redhat Enterprise 4.0
The following steps give simple steps to install CVS software on Redhat Enterprise Linux 4.0.
1) Download the tarball cvs-1.11.1p1.tar.gz
2) Run "gunzip cvs-1.11.1p1.tar". You will get file called cvs-1.11.1p1.tar.
3) Then extract this file using command
"tar -xvf cvs-1.11.1p1.tar".
4) Then go to directory cvs-1.11.1p1.
5) There you will find a file called INSTALL. Read it once carefully.
6) Now run the command "./configure."
7) Build it using the command "make".
8) Install binaries/documentation using command "make install".
9) Now open file called /etc/services and add the following lines.
Cvspserver 2401/tcp # CVS client/server operations
cvspserver 2401/udp # CVS client/server operations
10) Open file called /etc/xinetd.conf and add the following lines to that file.
service cvspserver
{
Port = 2401
socket_type = stream
protocol = tcp
wait = no
user = root
passenv =
server = /opt/bin/cvs
server_args = --allow-root=/home/cvs -f pserver
env = HOME=/home/cvs
log = /var/log/cvslog
}
11) Space on both sides of = in the above file is a must.
12) Restart xinetd services by running command " services xinted restart "
13) Check whether CVS is running on the port 2401 by using the following command "nmap IP |grep 2401". If the CVS server is running correctly it will give output as "2401/tcp open cvspserver ".
It doesn't output like "2401/tcp open cvspserver"
