Server :: Redhat - Solaris - Host Went Down - RCA ?
May 1, 2011
My server running on RHEL/Solaris went down of its own. I have rebooted the box and now the host is up. what are all the log files do i need to check to find root cause for this issue. I have already checked /var/log/messages and sar logs but not of much help.

I'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.

This is actually a question regarding RHEL 5.5. rather than CentOS but I understand they are very similar.With Solaris we use SMF to ensure that certain Java process are continuously running.If SMF notices that Java process has stopped it will run a start script, if we want to stop it, it will run a stop script.What could be use in RHEL?

I have an application running on a Solaris 10 server and I am getting the display on my Ubuntu notebook (10.04 lucid with kernel 2.6.32-23-generic and GNOME 2.30.2). But the problem is the fonts don't display well. So I tried to connect to the font server running on the Solaris server.
I tried all these variants:
xset fp+ tcp/<hostname>:7100
xset fp+ tcp/<hostip>:7100
xset fp+ tcp/<hostname>:/7100
xset fp+ tcp/<hostip>:/7100
[Code]....

Bit of an odd one, this. I've migrated a website from my old server to a new machine. Both servers run Ubuntu + Apache2. Both only serve a single site, apart from the default site.I've flipped the domain name to the new IP address.The trouble is that after moving the virtual host config over into sites-available, with the necessary link in sites-enabled, Apache attempts to serve from the default web root (/var/www) rather than the actual site content (in /var/www/technology). So for example, an attempt to browse.

i am bit confused about /Usr /Var /Boot partitions, as i need to manage perfectly in 130 GB
if i go with 4 Gb swap and remaining for " / " is that will be fine ? should i need to specify partition sizes separately for / tmp /var / usr ..

I have an opensuse 11.3 install which I want to set up as a network boot server to install Solaris 10 on a Sun Ultra 10 client. According to what I've read, this requires rarpd and tftpd which I've set up on opensuse, but also bootparamd which I can't find for 11.3. It seems it was last included with opensuse 9.2. Does anyone know if it's available, if I could use the suse 9.2 version, or any alternative?

We want to begin centralizing our system logs to a dedicated server, using a daemon that is flexible and offers more features. After some research, I decided to give rsyslog a whirl (versus syslog-ng).roblem has come down to compilation errors which, unfortunately, I've not been able to resolve otherwise (rsyslog forums) and it appears this is a larger problem with the product. So before I begin making another decision, I wanted to get some input from others here.Here is a snippet of the errors:
Code:
/usr/local/src/rsyslog/rsyslog-5.4.0/runtime/queue.c:1291: undefined reference to `ATOMIC_SUB'

Installation 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"
