TFTP: Transfer timed out.
Hello,
I'm trying to configure a RHEL 5.5 system to support TFTP transfers (backup Cisco IOS and configs). I've used several installation and configuration tutorials to get started. I believe I have everything configured properly but I'm receiving timeout errors. I've broken my syntax into three groups, Environment, Cisco attempt, and local attempt. Any help would be appreciated.
Thanks in advance,
Rob

The root directory for tftp is /tftpboot/ so you do not have to specify it when getting a file i.e. just try
tftp> get Cisco_2911.cfg

Same error
Hello Michael,
I tried as you suggested but received the same errors:
Cisco Attempt
Code:
Cisco_2911#copy run tftp
Address or name of remote host []? 192.168.3.6
Destination filename [sv003_srvc_rtr01-confg]? Cisco_2911.cfg
.....
%Error opening tftp://192.168.3.6/Cisco_2911.cfg (Timed out)
Cisco_2911#
Local Attempt
Code:
[root@RHEL_PC ~]# tftp
(to) 192.168.3.6
tftp> get
(files) Cisco_2911.cfg
Transfer timed out.
tftp>
Any other suggestions on what to try next?
Thanks!

You might try disabling selinux if enabled to see if this is causing your problems.
