SSH Problems

OK, so I’ve upgraded my laptop to Fedora 15, and want to restore the backup, but I can’t ssh into it. Here’s what happens:

[simberg@linux-host ~]$ ping 192.168.0.105
PING 192.168.0.105 (192.168.0.105) 56(84) bytes of data.

ssh: connect to host 192.168.0.105 port 22: No route to host
[simberg@linux-host ~]$

So I can ping it, but it won’t connect. I’ve installed opensshd on the laptop, I’ve enabled it, and the firewall has port 22 open. I can also ssh into it from a terminal on the machine (e.g., ssh localhost or ssh 192.168.0.105), but not from another computer on the network. Any ideas?

Ethernet Bleg

So I’m backing up my laptop in preparation for an upgrade from Fedora 13 to 15, and I notice that the data transfer speed is only about half a meg per second. Here is the output of ‘ethtool eth0’:

Any ideas what the problem is?

SoCal Verizon

Anyone else having slow connection problems? I’m dropping packets, and some sites (e.g., National Review) are timing out. I’ve also had to reboot my modem a couple times today (I’m on FIOS). There’s a half-hour wait time for help on chat.

[Update a few minutes later]

Here is the chat session so far:

Chat Subject:Slow Throughput
Your Question:Slow connection.
A Verizon Service Representative will be with you shortly. Thank you. (17:37:58)
Agent Kapil has joined. (17:38:13)
Kapil : Chat ID for this session is 08291149279. (17:38:13)
Me (17:38:24): Dropping packets, have to repeatedly reboot modem.
Kapil(17:38:29): Thank you for contacting Verizon HSI Technical Support. My name is Kapil and I am the technical support analyst assigned to help you. Please stay online for a few moments while I review the information generated by your trouble ticket.
Kapil(17:39:05): As you are having a FIOS account. Please stay online with me while I connect you to our FIOS department.
This session is being transferred. (17:39:15)
17:54:53 Estimated wait time is 5 mins 15 secs. We apologize for the delay. You are 22 nd in the queue.
Me (17:39:55): 36m wait time? That tells me I’m not the only one…
Me (17:46:33): OK, time is jumping around.
Me (17:51:39): OK, now what how much time?
Me (17:52:27): If there are still 21 ahead of me in the queue, it’s hard to see how it will only be three and a half minutes.
Me (17:54:19): Hello?
Me (17:54:24): I have a life.
Me (17:54:53): Now the time is back up to five minutes. No, six. This is ridiculous.
Me (17:57:01): OK, now it’s back to 21 minutes.
Me (17:57:37): If I were just working, I might keep an eye on this, but I have to make dinner.
Me (17:59:06): This is pointless. I have no idea how long it will be until I get help. Closing this effing chat window, so I can get back to life.

My Office Is Broken

Open Office, that is, on Fedora 14. I click on a document to open it, or try opening from the menu, and it says “starting open office,” spins an icon for a few seconds, and then nothing. I tried removing and reinstalling, and no change. I recently did an update on my Nvidia drivers, which included a new kernel. I of course had to reboot (something I am always loathe to do). I think that’s when the problem started. Any ideas out there? This is really an emergency. If I can’t get it fixed, I may have to do a lot of my writing on a different machine, maybe even a Microsoft one, and one not in my office.
