Can't re-establish SSH or VNC sessions after crash

Greetings:
I use sshfs and JollyVNC for secure Airport connections between Macs. I had a bad unrelated software crash and since am unable to get sshfs or JollyVNC to accept my passwords though I can do unsecure connect without using passwords but that's very unwise in my area. Console shows this during my Airport login attempts:
Apr 30 11:42:44 iceEgg2 sshd[1120]: error: Could not load host key: /etc/ssh_host_dsa_key
Apr 30 11:42:45 iceEgg2 sshd[1120]: error: PAM: Authentication failure for illegal user Thora from 10.0.2.2
Apr 30 11:43:08 iceEgg2 DirectoryService[44]: Failed Authentication return is being delayed due to over five recent auth failures for username: Thora.
Any clue how I repair this would be most appreciated!

Accidentally pushed "start new session" after crash. Tabs are gone from history.

After one of the ten crashes per day since I upgraded, I accidentally pushed, "Start New Session" instead of "restore". So, my '''closed window/tab records were wiped out''', and in my history, it only has those tabs that I opened anew this morning - NOT the ones I had saved so I could look at them later. A lot of these I had not bookmarked yet.

If you haven't closed Firefox then see if you still can restore that session via Firefox > History > Restore Previous Session.
You should update the Flash and Java plugin to the latest versions

Firefox will not restore session after crash

Hello, I am writing because whenever I resume Firefox (like from a crash or restart), it will not reload my previous pages. Instead it will only open a new window and I have to dig through my history to find and reload the pages from my previous session. Firefox is set to remember history and to show my windows and tabs from last time.
My Firefox version is up to date (although it seems that the version doesn't matter). I have gone into about:config, set browser.sessionstore.max_tabs_undo to 40, set browser.sessionstore.max_windows_undo to 10, and reset broser.sessionstore.resume_from_crash to true. None of that has helped and the latter kicks back to false every time Firefox restarts.
I have had this issue occur a couple of times in the past, and if I recall, I had to create a new account. If told how to, I can do this again, but I would prefer to get to the root of the problem to prevent this from occurring again (plus I'd hate to lose all my history again). If anyone can help me with this, I'd greatly appreciate it. If you need to know anything else, feel free to ask. Thank you.

I have finally found a working solution with help from Zzxc.
You do have to create a new profile, but you can save everything from browser history to ad-ons to dictionary. It even restored the pages I had open in the old profile.
https://support.mozilla.com/en-US/kb/Managing+profiles
This shows you how to create a new profile. I left the old one and named my new one as "name" - New Default - "current date"
http://support.mozilla.com/en-US/kb/Profiles#How_to_find_your_profile
This shows you how to find all of your information and settings for both profiles. It shows you what file is what (so you can pick and choose), but if you just copy everything from inside the old profile folder and paste it into the new profile folder, you should be gold.
This seems to have worked for me. If it turns out that I copied and pasted the problem as well, I will post it here, but as of now, everything appears to be in working order. Thanks.

Slow SSH and VNC

Hi!
I'm visiting my family at the moment, and tried to call home to my desktop from my laptop that I brought with me. I've tried to use both VNC and SSH, and both are extremely slow. I'm sitting on a 24/2 mbps-line at the moment, while my desktop is connected to a 10/10 mbps-line. VNC is just too slow be usable, and sometimes it freezes for a long time. SSH also feels very sluggish, and when I tried to copy a file with sshfs I got a speed of around 20 Kb/s. At first I though there was something wrong with the connection, but then I started apache on my desktop and downloaded a file over http, and the speed was stable around 900 Kb/s as it should be. A traceroute shows that the trafic goes directly from my familys ISP to my ISP, and ping shows times around 20 ms. So I can't understand why SSH and VNC is so slow, and I don't even know where to begin troubleshooting. If anyone have any suggestions on what might be wrong I would be very grateful.
Both of my computers run Arch64, and my desktop is connected via cable to a router while my laptop uses wireless (Intel 4965), also to a router. The routers are pretty much identical, both being Asus WL-500G Premium with DD-WRT firmware. The necessary ports are of course open, and I use port 2200 for SSH and 5900 for VNC.

Could be one of the isps doing QoS on anything not http based traffic. Comcast sometimes _appears_ at least to be slowing down some of my non-http traffic for instance...
Could be packet loss.
Could be a busy neighborhood loop on a cable network (if that is what one end is..).
Could be.. just about anything...
Run iperf on both ends or something, and see what it says..
Look at tcpdump output (or wireshark).
poke around. try some stuff.

SSH to Lion Server: The authenticity of host ... can't be established.

In Server.app, when trying to SSH into a 10.7.4 Lion Server, I get the following reponse:
The authenticity of host '<server.domain.com> (10.0.1.xxx)' can't be established.
RSA key fingerprint is xx:xx:xx:xx:xx:xx.
Are you sure you want to continue connecting (yes/no)? no
Host key verification failed.
How do I set up sshd to use the server's signed SSL certificate for authenticity establishment?
TIA,
Larry Goldman

To answer my own question:
In general, SSH on the client in coordination with the SSHD daemon on the server use an authentication system that is separate from Lion Server's signed-SSL certificate methods. The SSH-specific keys that are exchanged between client and server are created by the ssh_keygen command. For details see the man pages.
The first time a client SSH's into a server, normal behavior is to be presented with the message: "The authenticity of the host 'server.domain.com' can't be established." along with the server's RSA key fingerprint. This fingerprint must match the one displayed by running the following command -- locally -- on the 10.7.4 Lion Server:
ssh-keygen -l -f /etc/ssh_host_rsa_key
The user has to visually compare the key strings to determine if they match. If so and the connection continues, that server's RSA key fingerprint is added to the file ~/.ssh/known_hosts (in a hidden folder in the user's Home folder).
Alternately, there is a way to add the server's RSA key fingerprint to a zone file for the domain, using a SSHFP DNS Record type, but I have not tried this myself.

Lion server on Mac mini server stop responding to ssh and VNC (other services like mail, ical works well)

Lion server on Mac mini server stop responding to ssh and VNC (other services like mail, ical works well)
Version is Lion server 10.7.4
When I attach a monitor to it, I saw all the buttons and menus stopped responding too. I can only push and hold the power button on the box to shutdown.
It only started happening recently.
Anyone has any clue?
Thanks for the help in advance!!!

Found that the second hard drive is broken. I have to go to the apple store to have it replaced.
I had to press the power button to turn the server off for several times, then the broken hard drive went disappeared. After that, I had to disable the Spotlight. Then the server went back to work normally.
Now I made a CCC copy of the primary hard drive, and would like to have the server run on the external raid disk (connected through thunderbolt). Does anyone have previous experience with it? Any expectable drawback or issue with this setup?

Copy to/from clipboard not working to/from VNC session

Using the default VNC client that comes with Snow Leopard, I am unable to copy/paste text from/to the VNC session window to/from my Mac. Under the ScreenSharing View menu, I selected 'Show Toolbar". I see the 2 icons for "Get remote clipboard contents" and "Send clipboard contents to remote clipboard" but the Icons are disabled. How do I enable the icons? Is there any other way to copy/paste?

Are you connecting to another Mac running Snow Leopard? Or Leopard? Or a non-Mac? I believe that OSX's implementation of VNC (a.k.a. Screen Sharing) can only transfer clipboards between Macs. (Correct me if I'm wrong.) (I'm not exactly certain about clipboard compatibility between Leopard and Snow Leopard, but I know it won't work between Mac and and a PC running VNC. (Or at least it doesn't work with the VNC client's I'm using on my PCs.)

Can't write to ssh known_hosts file

Awhile back I did a complete restore from backup of an MBP. Since then this machine's ssh client can no longer will write to the ~/.ssh/known_hosts file:
The authenticity of host 'dhcp167 (172.31.0.167)' can't be established.
DSA key fingerprint is 66:3d:0c:31:e0:07:09:6b:21:f9:8c:79:40:50:01:45.
Are you sure you want to continue connecting (yes/no)? yes
Failed to add the host to the list of known hosts (/Users/dnewman/.ssh/known_hosts).
I have write access to this file:
dhcp130:~ dnewman$ ls -l /Users/dnewman/.ssh/known_hosts
-rw-r--r--@ 1 dnewman staff 36439 Sep 26 17:51 /Users/dnewman/.ssh/known_hosts
How to remedy this error?
thanks

Can you manually edit the file?
No. vi thinks it's a readonly file despite the 0600 perms
What do the permission for path leading to the file look like?
dhcp130:.ssh dnewman$ ls -ld /{,Users/{,dnewman/{,.ssh}}}
drwxr-xr-x 36 root admin 1292 Dec 15 16:07 /

-rw-------@ 1 dnewman staff 36439 Sep 26 17:51 known_hosts
com.apple.metadata:_kTimeMachineNewestSnapshot 50
com.apple.metadata:_kTimeMachineOldestSnapshot 50
The permissions thing is interesting. Is the problem that I had a different UID or GID on the "old" machine image (the one I restored from) than what's currently running? And if so, how to remedy?
thanks much!

Can I download a file in different sessions or should it be in a single session? In other words can I pause the download of a file, shutdown/restart my system and then resume download from where I left off? Or will it start from the very beginning?

Can I download a file in different sessions or should it be in a single session? In other words can I pause the download of a file, shutdown/restart my system and then resume download from where I left off? Or will it start from the very beginning?

If a server supports resuming downloads then the download should continue where it left off.<br />
You can test that by simple starting a large download and wait a minute or so before pausing it.<br />
Then you can close and restart Firefox and see if resuming works.
You can set the pref browser.download.manager.quitBehavior to 2 on the about:config page.<br />
That will make Firefox ask for confirmation if you want to cancel the download if you close Firefox.
See:

Hi,
The purpose of service locator is to abstract the lookup of the server side services like ejb and DSNs. It should be a normal java class but as such there is no such restriction. You can have a look at the service locator patter at the j2ee blue prints.

Can I load adobe audition 3.0 sessions to garage band?

Can I load adobe audition 3.0 sessions to garage band?

I don't believe you can in its native format. However, you can certainly add a stereo mix or individual audio tracks from an an Audition session into GB (just as you would add any *standard* audio file to GB).
