Week Five: Parts One & Two

There are several sections of this week's lesson that I am simply skimming over and holding for later review due to a shortage of time.  I am going with recommendations on the most critical parts, plus anything else that might catch my eye.

Email & Newsgroups:  Using Pine

I get the mystery no mail in my inboxes. One had 1500 messages per C-Panel but zero messages per Pine. If I want to use this I need to go and configure proper paths. Might come in handy one day in case of emergency.

Due to shortness of time and lack of real need for Pine at this point, I will pass for now, but may revisit later. Notes are here to remind myself to check and properly set mail account paths.

One thing I would be interested in is figuring out if there is a way to mass delete mail. I could only find one by one deletions during my quick visit. This might be a fast way to dump duplicates left on my server, spam boxes and such.

Alternative Browsing: Lynx

I did find this interesting and poked around in a few sites just to see how things worked.  This is another section I am holding for future fiddling.

My Current Lynx Version:

<< ping >>

My host does not make  << ping >> available to [gap] non-privileged users for security reasons.  There are many commands of this nature they will allow upon request, but not thing one.  [I was so sure I should be considered privileged. haha]

If I had it, or get it at a later date [doubtful], I need to remember to use Ctrl + C to quit and not keep looping pings at a server.

-bash2.05b@gemini [~]$ping slackershandbook.com
ping: icmp open socket: Operation not permitted

-bash2.05b@gemini [~]$whereis ping
ping: /bin/ping /usr/share/man/man8/ping.8.gz
-bash2.05b@gemini [~]$which ping
/bin/ping

<< traceroute >>

Tool for checking network problems. Located in /usr/sbin.  Had to request this command be unlocked by my server host.

I have also now added << traceroute >> to my .bash_profile along with the alias << trace >> so it does not have to be typed in every session.

<< nslookup >>

Look up information via name servers.

-bash2.05b@gemini [~] $nslookup catartis.com
Note:  nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead.  Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
Server:         127.0.0.1
Address:        127.0.0.1#53

Name:   catartis.com
Address: 63.247.132.12
-bash2.05b@gemini [~] $nslookup ns.hmdnsgroup.com
Note:  nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead.  Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.

Address:        127.0.0.1#53

Name:   ns.hmdnsgroup.com

<< host >>

A quick check of IP address.

-bash2.05b@gemini [~] $host lvsonline.com
lvsonline.com has address 128.242.147.31

<< dig >>

A more verbose and robust version.  It can also be used with an IP number for reverse look-up.  Adding the flag -x will show which network a domain is located within.

-bash2.05b@gemini [~] $dig jumpserver.net

<< whois >>

Works like domain look-ups around the web to see if a name is available.  If taken, shows who owns it.

-bash2.05b@gemini [~] $whois lvshost.com
