Bah! Not able to sftp! But ssh works! WTF!
Wasnt able to sftp (filezilla, winsftp, sftpdrive, all fail) to my linux box, but was able to ssh like normal. SFTP gives weird error “Received message too long “. Realized the fucking bashrc/profile.d causing this issue. When ssh starts up the sftp subagent the shell must be clean, else the sftp may fail with error like this.
#sftp from localbox.
g@utam-f9:/temp $ sftp -v root@localhost

A quick inspection reveals, few lines in my bashrc are using colors to echo out some funky message, whenever I login to root. So a quick work around :)
if [ ${TERM} != “dumb” ]; then
