SSHD LAN connection lagging big time!

[oram]

I run Arch Linux and SSHD works fine offsite. Wherever I go during the day I can always login. However, when I get home at night and I try to ssh into my box from another machine on the local network; ie:

ssh -l oram 192.168.1.109

It almost always comes back with 'connection closed' or when it does work, it is slow as hell. I have tried to figure this out but I can seem to make any progress. I usually connect to the linux box with a powermac running OSX[/b]

Try running a ping -c4 and a tracepath to the Linux box. Post the output here.

You could specify the -v option to look at the debug messages. More v's is more info
Maybe that way you could see where the delay is..

From here i am inside the box, however, the text highlighted in red is where the shelling in seems to hang.

For this you have to add your home_pc_IP to the /etc/hosts.allow

or Allow your ip in /etc/sshd_config like this

AllowHosts your Home ip


Try this....................

[oram]

#let everyone connect to you
sshd: ALL
sshd: 192.168.1.100/192.168.1.254

#Or you can restrict it to a certain ip
#sshd: 192.168.1.100
#Or restrict it to a certain ip range
#sshd: 10.0.0.0/255.255.255.0

EOF

the highlighted line is what i added upon your request. I thought i'd add all the possible router ip's. This still doesn't make a difference. I'm thinking that there is some kind of problem with the "A parameter was malformed" error line above from debug: 1

Thanks

I am having an identical problem with my Powermac G4 and Powerbook. The problem appeared in mid January, and I have tried everything to fix it. My "ssh -v" log looks exactly like yours.

Has anybody else experienced this problem?

Reading over this thread maybe I am confused but in the original post you logged in as oram and the second one you logged in as nick Did you mean to do that and is nick a username on the box you are trying to ssh to?
