Cisco Questions...

[iphonogasm]

Ok so i will put some cisco questions here... im getting quite into cisco so i think i will post a bit here...

My first issue, a bit of a biggie, and annoying

is TELNET (i know its not the most secure)

but im trying to configure telnet on my 1841. And i can get it working....but

I configure every

en
conf t
no ip domain-lookup

int fa0/1
ip address 10.0.2.250 255.255.255.0
no shutdown

hostname ROUTER1

line vty 0
password cisco
login

line vty 1
password cisco
login

wr mem

copy run start

copy run flash

why when i reboot the router all configuration is the same EXCEPT i cannot telnet into the router anymore....however with this configuration before reboot..i can telnet into it

THANKS!!

 

[ICTCity]

it sounds like a bug to me...

Try to update the firmware first (good luck ... hard to find but try with google or similar).

Then post a show run before and after restart.


PS: you don't need copy run flash, just wr mem & copy run start

Ok thanks, i thought i may have been copy flash as it has a flash card plugged into it, almost like a MD card side

Config before reboot, Line vty configured wr mem and copy run start.

Ok..so went away for the weekend... just got home and tried it again. and its working. Why this is i am really not sure...al i cam think is i was copying the start up config to the running, but this is really not like me, but having said that, maybe i just need a weekend away HAHA!!

Now, my next little issue which ive had a small issue with prior to this one is.

I have no DNS when use my 1841 as a router, i cannot even ping interlally from the router itself.

I try ping 10.0.2.x and 8.8.8.8 with a 0% success rate

sh ip route displays a default route for network 10.0.2.0

Any ideas? Cheers

 

[ICTCity]

Try to ping 10.0.2.250

It should work.

Anyway update the firmware

 

[iphonogasm]

yea ok now i just tried to telnet again, with no reboot since last reboot and i get no password set.

I am setting same password and login on line vty 0 and line vty 1

could this be the problem

Im guessing so lol

 

[ICTCity]

line vty 0 1
password cisco
login

Means that 2 telnet sessions require authentication with Cisco password.

line vty 2 4
login

Means that you CANNOT use these connection.

You need to logout of each telnet session.

 

[iphonogasm]

ok thanks

 

[iphonogasm]

do you think you could spare me 10 mins to walk me though some router config. I have enabled DHCP and tested all is good.

I have added a route for 10.0.2.0 255.255.255.0

but still i am unable to ping anything on the local network (ever the router from the router (loopback))

and im still getting no DNS cannot ping 8.8.8.8 of course as i cannot ping anything on the LAN

Once i fix the DNS issue, i can use this router as default gateway and DHCP server

I swear this router seems a bit dodgy, the guys is positive there is no issues with the router, and i dont know an awful lot...


Thanks!
