Export NFS through Firewall

rpcinfo -p will list nfs ports used

copy the following from http://linux.derkeiler.com/Mailing-Lists/Fedora/2007-07/msg02399.html

1) You must have ports 2049 tcp+udp and 111 tcp+udp open in the nfs
server firewall to allow clients to talk to nfs and portmap, respectively.

2) There are a number of other daemons on the server, associated with
nfs, namely rpc.statd, rpc.lockd, rpc.mountd and rpc.quotad. These must
also be accessible to the clients. By default these start on random
ports, which the firewall couldn't care less about. So to allow clients
to get to the rpc services you must
2a) force the rpc services to start on pre-assigned ports of your
choice, like 4000 to 4003.
2b) open ports 4000-4003 tcp+udp in the firewall (or whatever
ports you used at (2a).


Now, here is how you do all this. You implement 2a by creating a file
/etc/sysconfig/nfs with the following contents:

STATD_PORT=4000
LOCKD_TCPPORT=4001
LOCKD_UDPPORT=4001
MOUNTD_PORT=4002
RQUOTAD_PORT=4003

Restart nfs.


The rest is opening ports into the server firewall, which is a separate
matter. On the server, something like

/sbin/iptables -I RH-Firewall-1-INPUT 10 -s 192.168.1.0/255.255.255.0 -p
tcp -m state --state NEW -m tcp --dport 4000:4003 -j ACCEPT

will insert a rule at position 10 (if 10 is the position you want) in the
RH firewall that opens the range 4000-4003 for incoming tcp connections
from the local network. Run then the above command again with udp instead
of tcp. Do the same (tcp+udp) for ports 111 and 2049. Finally, save the
new firewall configuration

/sbin/iptables-save > /etc/sysconfig/iptables # after backing up old
iptables first.

and restart iptables

/etc/rc.d/init.d/iptables restart

Build my Linux Software RAID5 at home

It is great.

I create raid5 with 3 disk
then add one more disk by

mdadm --manage /dev/mdX --add /dev/sd?1
mdadm --grow /dev/mdX --raid-devices=4 (original is 3)

This will reshape at the back. Very slow but find the below to speed up

In Fedora 7, original value
cat /proc/sys/dev/raid/speed_limit_min ==> 1000
echo 100000 > /proc/sys/dev/raid/speed_limit_min

MBR fixes

MBR appears to be blank.
You can add an MBR to this device with
# cat /usr/lib/syslinux/mbr.bin > /dev/sdk

Sybase ASE on Linux FAQ - Fedora

Extract from the link below:

• Running ASE 12.5.1 on Fedora

Fedora is the new name of Red Hat's "consumer" releases (as opposed to their "Enterprise" releases).

ASE 12.5.1 requires a Java JVM to install. I downloaded mine from http://java.sun.com/j2se/1.4.2/download.html. There are some instructions on performing the JVM install at http://fedora.artoo.net/faq/#Java.

Next, the dataserver binary is linked with some older libstdc++.so libraries. To get these libraries you need to install compat-libstdc++-7.3-2.96.118.i386.rpm. This is available in the Fedora distribution.

Now you are ready to go ahead and install.

Note that the 12.5.1 installer doesn't create a "sybase" user for you, doesn't install any rc files, and doesn't edit /etc/ld.so.conf, so you'll have to do that yourself. Also remember to set the kernel.shmmax entry in /etc/sysctl.conf and run /sbin/sysctl -p before building a new server.

How To Build a Loadable Extension Shared Library on Linux
0. untar latest sqlite3 source code in a new directory
1. cd to the newly untarred sqlite directory
2. Comment out the line in Makefile.in to enable loadable extensions:
# TCC += -DSQLITE_OMIT_LOAD_EXTENSION=1
3. ./configure LIBS=-ldl && make sqlite3
4. export LD_LIBRARY_PATH="`pwd`:$LD_LIBRARY_PATH"
5. gcc -I`pwd` -shared src/test_loadext.c -o half.so
6. ./sqlite3
SQLite version 3.3.17
Enter ".help" for instructions

Apache self signed certificate for Fedora7

Install the below:

mod_ssl-2.2.4-4
distcache-1.4.5-14.1
httpd-2.2.4-4
openssl-0.9.8b-12.fc7

cd /etc/pki/tls/certs
review make-dummy-cert and make copy say my_make_cert and modify the content of the copy
i.e. highlighted in red below:

#!/bin/sh
umask 077

answers() {
echo --
echo SomeState
echo SomeCity
echo SomeOrganization
echo SomeOrganizationalUnit
echo localhost.localdomain
echo root@localhost.localdomain
}

issue the below
./my_make_cert test
split the file test in between the lines into two parts:
-----END RSA PRIVATE KEY-----

-----BEGIN CERTIFICATE-----

The upper part save as file /etc/pki/tls/private/localhost.key
The bottom part save as file /etc/pki/tls/certs/localhost.crt

This matches with the default /etc/httpd/conf.d/ssl.conf that come with the mod_ssl rpm package
