iphonogasm Posted November 22, 2012 Posted November 22, 2012 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 Posted November 23, 2012 Posted November 23, 2012 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 ;) Quote -------------------------------------------------------- Tu peux aussi crire en franais. Du kannst auch auf Deutsch schreiben.

iphonogasm Posted November 25, 2012 Author Posted November 25, 2012 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. router1#sh run Building configuration...

iphonogasm Posted November 25, 2012 Author Posted November 25, 2012 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 Quote
ICTCity Posted November 25, 2012 Posted November 25, 2012 Try to ping 10.0.2.250 It should work. Anyway update the firmware ;) Quote -------------------------------------------------------- Tu peux aussi crire en franais. Du kannst auch auf Deutsch schreiben.

iphonogasm Posted November 25, 2012 Author Posted November 25, 2012 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 Quote
ICTCity Posted November 25, 2012 Posted November 25, 2012 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. Quote -------------------------------------------------------- Tu peux aussi crire en franais. Du kannst auch auf Deutsch schreiben.

iphonogasm Posted November 26, 2012 Author Posted November 26, 2012 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! Quote
ICTCity Posted November 26, 2012 Posted November 26, 2012 Post result of: Sh ip int br Sh ip route Quote -------------------------------------------------------- Tu peux aussi crire en franais.
