Operating Systems Linux Red Hat Oracle Linux issue - all files FTPed to it from windows need to to be processed with dos2UNIX Post 302980211 by Albert_Pinto7 on Thursday 25th of August 2016 09:29:48 AM

Oracle Linux issue - all files FTPed to it from windows need to to be processed with dos2UNIX

Hello Friends,

I have observed one recent issue about ftp from windows to Linux.

Initially we had Solaris unix and any file sent from windows to solaris via ftp (binary or ascii) worked smoothly.
Say for e.g if I sent a shell script to soalris from windows, that script used to run corectly. So did an encrypted file which got successfully decrypted on Solaris.
Things changed when we got Redhat linux which replaced solaris and now all the above file transfers have caused issues. In that, once the file was successfully transferred to Linux, and if you open the file in Vi editor, you will see [dos] at the bottom. This is not about ^M characters. I assure that files are sent in correct mode. So we dont get ^M chars. Only the [dos] at the bottom when opened in Vim. so the shell scripts having [dos] at the bottom dont run and error out.
The binary files sent via ftp also dont work when ran on Linux.
Thus, all these files run only when dos2unix is ran on them. On text files the [dos] symbol goes away and bainary files get run successfully then.

My question to experts here is, why in solaris, a file which is sent in correct mode from win to solaris does not need a dos2unix processing and why those files need dos2unix processing when sent from win to Redhad or Oracle Linux.

Thanks,
Albert
