Description Bill Thompson 2001-02-20 21:17:05 UTC
From Bugzilla Helper:

User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Mac_PowerPC)

TFTP connections give "TFTP: error code 2: Access Violation" on read 
and write. Tested on Cisco IOS 12.0, RH6.0, and RH7.0.

Reproducible: Always

Steps to Reproduce:

1. Activate TFTP server.

2. connect with TFTP from a diffrent machine on the network.

3. set verbose mode on "verbose on"

4. Try to send or receive a file using normal TFTP methods.


Actual Results:  In verbose mode you will get the message:

Error code 2: Access violation

Expected Results:  The file should be copied from or to the tftp server.

I have duplicated this with two seperate RH7.0 installs on diffrent  
computers. Either it is a bug with the tftp-server 0.17-5 package or 
there is an undocumented security restriction in RH7.0. Telnet, SSH, 
and FTP access all behave normally on the systems affected.

Comment 1 Pekka Savola 2001-02-20 22:46:33 UTC
tftp-server access semantics have changed from RHL62 to RHL7.

If you don't enable chroot, you must do like:

get /tftpboot/file.gz

RHL62 version would allow you to omit tftpboot.

Comment 2 Helge Deller 2001-02-21 12:46:13 UTC
fixed in tftp-server-0.17-9,
either update to this version from rawhide, or follow pekkas comments and use 
"get /tftpboot/file.gz"

Comment 3 agyorgi 2001-02-28 03:40:29 UTC
tftp-server-0.17-9 is not in the Raw Hide section... in fact, there isn't any version of tftp-server in the Raw Hide section. I too am facing
similar issues with tftp. Please point us to the right direction to obtain it.

Rawhide isn't updated too often, but you can also get this from the beta section:
