commonly asked questions
Q. I have a lot of RAM.. but Linux reports only 64MB!!!
A. Don't panic ;) For example, if you have 96MB of RAM,
add append="mem=96M" to /etc/lilo.conf.
Q. Things just don't work! I get error messsages like 'permission denied' etc.
A. As a general rule of thumb, always check your file permissions. For example,
if you cannot dial out as a user, check whether your /dev/modem has been
read&write-enabled for group and others.
(Warning: Permissions are delicate stuff. Always consider security issues.)
Q. How do I launch X Windows in 16-bit color?
A. startx -- -bpp 16
Q. I cannot read my Win95 OSR2.1 or Win98 partitions from Linux.
A. Your kernel is unable to read FAT32 partitions. Install a patch or upgrade to kernel >= 2.0.34.
Q. pppd does not work!
A. There can be various reasons. However, to establish a pppd connection, your /etc/resolv.conf
and /etc/ppp/options must be properly configured. Here are samples:
contents of /etc/resolv.conf:
search rs.internic.net
nameserver 202.54.30.1
nameserver 202.54.30.2
contents of /etc/ppp/options:
0.0.0.0:
/dev/modem
lock
crtscts
defaultroute
asyncmap 0
mtu 552
mru 552
Q. What are .rpm files?
A. RPM stands for Redhat Package Manager. To install .rpm files, you do a rpm -i [file].
Q. I have just downloaded a .tgz or .tar.gz file? What do I do?
A. First, you'll have to understand what .tar files and .gz files are. Basically, a .tar file just
concatenates many files into a single file. No compression is done. (tar is an archiver)
A .gz file is similar to a .zip file which so many of us are familiar with on the Windows platform.
(gzip is a compression program)
Consider a directory named project. All the files in the directory is tar-ed into a file called project.tar.
The program gzip is used to compress the project archive, yielding a new file project.tar.gz.
So, to reverse the process, you gunzip project.tar.gz to get project.tar and
issue a tar -xvf project.tar to obtain the project directory. Simple? :)
There are neater commands involving pipes but it's up to you to explore yourself (the essence of Linux!)
