Slow connection with SSH
Hello,
Sorry I have another question about the DNS-323.
I've install fun_plug and transmission, enabled ssh, and disabled telnet. However, when I try to SSH into the box, it takes a long time for it to pop up the password prompt. This happens in both putty and winscp.
Are there cerntain settings i need to change to make this work better?
Thanks,
Edward

Re: Slow connection with SSH
Hi there !
Sorry to put up this old thread, but I noticed that I've got the same issue as described above... When I try to ssh to the DNS-323, there is a long delay before the password prompt.
I tried using sshd without and with inetd but same problem in both cases...
Do you guys have the same thing ?

Re: Slow connection with SSH
Thank you very much fonz, I put UseDNS to no in sshd_config and now ssh connections are really fast !

Re: Slow connection with SSH
First, many thanks to fonz; fun_plug has saved me from Samba and made it possible to copy files with colons in their names over to the DNS-323... but I fear I'm having speed issues with SSH, too, though with the speed of file copying rather than connection. I have a gigabit router, and gigabit ethernet on my computer. I observed data transfer rates of about 8.5 MB/s when I tried to copy over ~/Music to the 323 via Samba... but now, via ssh, when I copy over some of the directories that samba refused to copy for me, I'm seeing 1.5 MB/s. Admittedly, 8.5 isn't all that great, so there are, I hope, other things I should check independent of ssh vs. Samba, but OTOH a factor of around six difference is definitely significant. What settings should I be looking at to improve the speed of transfer?

Re: Slow connection with SSH
Copying files via ssh is slow because the data is encrypted, which costs processor cycles, and the DNS doesn't have a very powerful processor. I think 1.5MB/sec is all you can get.
Maybe you can use ftp or nfs to transfer the files, or tar the files, copy them via samba, and untar on the box.
