I hav tried transport input all that gives : transport input lat pad v120 mop telnet rlogin udptn nasi I 've checkd ACL 10 , It's OK I don't have any username. I tried to remove ACL under vtty too I could run telnet to router, but when I type password, It did not work , did not give any thing. I could use console to login. BTW, I have just exactly the same configuration to the other router (IOS 12.1.5 T), the difference are IP addr. and so on.. Regards, >>> Jim Dixon <[EMAIL PROTECTED]> 04/02 8:12 >>> take your transport command (under VTY 0 4) and change it to transport input all does it let you telnet now? Yes? Then that was your problem, re-consider your transport command syntax and verbage till you get what you are after. No? Then it is most likely your access list 10 causing the problem. You do have a username/password configured in the router right????? Remove the access list from the VTY lines. Does it let you telnet now? YES? THen the access list IS your problem, now go fix it. NO? Then check out the following URL http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12supdoc/dsq cg3/qcddr.htm watch the word w- -rap Look at login authentication default It may be that your AAA authentication lines need to be configured differently. Remember that the router performs the first auth method that is configured then upon failing the second and so on until all have been exhausted, at which time it drops the connection and give error msg. -----Original Message----- From: Kim Quang Vo [mailto:[EMAIL PROTECTED]] Sent: Monday, April 02, 2001 12:46 PM To: [EMAIL PROTECTED] Subject: Can not telnet to router line aux 0 no exec transport input telnet Upgrading to IOS 12.1.5C E8 on 7206 I got these in under line vty transport input lat pad v120 mop telnet rlogin udptn nasi then I could not run telnet to router. transport output none line vty 0 4 access-class 10 in exec-timeout 60 0 password 7 xxxxxxxxxxx login transport input lat pad v120 mop telnet rlogin udptn nasi line vty 5 15 password 7 xxxxxxxxxxx login transport input lat pad v120 mop telnet rlogin udptn nasi Any hints will be appreciated Kim **************************************************************************** * * Kim Quang Vo - ElTele Xst Fredrik Selmersvei 2, N-0603 Oslo. phone.+47 23 18 12 08 mobile .93081208 fax. 47 23181961 **************************************************************************** * * _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
