The protocol obviously supports this as both sftp and the shell are over the same ssh protocol. That is why I thought that this ability might exist. > PuTTY does exactly that.

I suppose that OpenSSH might be the project to file the feature request to. I'll get on that. > More solutions (sshfs, or just giving up and typing several commands) > have already been posted here. Many workarounds, but the solution seems to be to file a feature request with OpenSSH.

You might like to try this. 1) Add to ~/.ssh/config ControlMaster auto ControlPath /tmp/%h%p%r (man ssh_config for explanation). 2) Fire up sftp sftp user(a)machine:/path 3) Within sftp, login to a shell on the remote system !ssh user(a)machine Exit the shell to return to the sftp prompt. 4) Use sftp's history to recall the ssh command as desired. Note that by using the control socket, the shell login uses the same connection as sftp. Consequently you don't have to enter the password again. Allow me to make a plug for the lftp package which I find more friendly and flexible than sftp (filename completion, get/put multiple files, and much more). At (2) enter lftp sftp://user(a)machine/path then carry on as before. I hope this helps. -- Cheers, Clive -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

There might be something possible with port forwarding, and perhaps an escape could be added to ssh to provide access to the sftp subsystem, but what I always do is just do the transfer separately, as you do, and keep track of the CWD myself. Transfers can be done from the same terminal by backgrounding the ssh connection and then using sftp or scp. In ssh and bash (see "ESCAPE CHARACTERS" in `man ssh` and "JOB CONTROL" in `man bash`): [ ~]# ll mime.py -rw-r--r-- 1 root root 16782 May 18 2009 mime.py [ ~]# ~^Z [suspend ssh] [1]+ Stopped ssh root(a)foo.com [tonyn(a)localhost ~]$ ll mime.py ls: cannot access mime.py: No such file or directory [tonyn(a)localhost ~]$ scp root(a)foo.com:mime.py . mime.py 100% 16KB 16.4KB/s 00:01 [tonyn(a)localhost ~]$ fg ssh root(a)foo.com [root(a)rapidxen ~]# You can keep sftp running and switch back and forth by "^Z" out of sftp and "fg %-" to go back to the "other" job, ssh. Use the up arrow into command history to avoid even typing "fg %-". Or, you could always use sftp or scp from the remote machine back to yours, if you open things up enough that you can ssh etc. into the local machine. (I have my firewall block connections from outside the local network, so I can do this locally but not remotely.) p.s. I hate screen. -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson(a)georgeanelson.com> ' <http://www.georgeanelson.com/> -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
