Month: March 2009
There have been times when I wrote an email, pressed send, then suddenly realized that I missed to mention something, or that I wanted to reply to all instead of one or vice versa, or some other likely reason.
During my Wireless Networking school days, I was working on this project with my group mates and we were communicating through email. I’m supposed to reply to all so everyone will be updated of the new developments, but sometimes, I already sent my reply email then realize that I only sent it to one person. That kind of situation is a little bit okay since it only is among my friends, and I could always just send again.
In my job email applications though, that probably has happened to me a couple of times or so. There was this time that I suddenly discovered that I missed an “s” in one word. It was so grammatically wrong and that simply irks me. Or there was this other time that I forgot to attach my resume and then realized it a second too late. No! No! Please don’t send!
Thankfully, Gmail has introduced the Undo Send feature in its Gmail Labs recently last March 19th, 2009. You can now take back the email you just sent as long as it is done within a five second time frame. It also has an option to adjust the time to ten seconds, if you prefer. However, it cannot pull back the email you sent once it’s already gone after five seconds.
In addition, there is also a Forgotten Attachment Detector feature in Gmail Labs that will stop you from sending an email if it detects that you mentioned attach but haven’t included any attachments. This actually has saved me once so far.
Of course, the best way to prevent these bloopers from happening is to be extremely careful in the email content you are sending. Double check, or even triple check. Be alert. Try to avoid sending an email when you’re not completely awake, or when you are feeling sluggish. (This is sometimes the reason why these things happen to me. Haha!)
David Davis wrote in TechRepublic about the ten commands that a Cisco professional or network administrator should know when using the Cisco IOS in routers, switches, and firewalls. This is a good reminder for me, and I’m glad to know that I have embedded all of it in my brain already.
Below is the list he made plus my comments on what I think about each item.
1. The “?”
This is the most helpful command ever. There are thousands of possible commands in the Cisco IOS and this is definitely useful when you don’t know or can’t remember the command to type, or the parameter that should come next.
2. show running-configuration (sh run)
If you want to check the current configuration of the router, switch, or firewall, this is what is used.
3. copy running-configuration startup-configuration (copy run start)
This command will save your current configuration, which is in the RAM, to the nonvolatile RAM (NVRAM). You can also use the copy command to copy to the TFTP server. If you must turn off your router, do not forget to use this command unless you don’t want to save the configuration changes you made.
4. show interface (sh int)
For troubleshooting, this command is used to check the status of the router’s interfaces.
5. show ip interface (sh ip int)
Much useful information about the configuration and status of the IP protocol and its services, on all interfaces are displayed with this command. Alternatively, you can add brief at the end of the command to get a shorter quick status.
6. config terminal, enable, interface, and router (conf t, en, int, router)
These are used to enter different modes in configuring the router.
7. no shutdown (no shut)
This is used to enable an interface, and also useful for troubleshooting when used with shut (to bring down interface then up).
8. show ip route (sh ip ro)
To check the routing table, use this command.
9. show version (sh ver)
This will display the router’s firmware settings, the last time the router was booted, the version of the IOS, the name of the IOS file, the model of the router, and the router’s amount of RAM and Flash.
This is helpful in troubleshooting. The debug command is used with other commands like for example, debug ip route.
Alright. That should be pretty simple to remember. Commands, stay in my brain please, thank you.
