Hi to all, i have a centos 5 machine, which i use as a pbx.

Its been online for more than 3 months and i never had an issue with it, now it wont let me connect via sftp with my ssh client, it gives me the error:

"failed to open a secure file transfer session" and after that error it gives me:

"file transfer server could not be started or exited unexpectedly
exit value 0 was returned most likely the sftp sever is not in the path of the user on the server side"

i already googled this issue and mos of the people can resolve this by changing a line on the sshd_config file, but in my case i am not able to save the changes it tells me permission denied, i hope some one can help me out on this, thanks in advance.

Jaime Gonzalez.
