ssh/telnet

ssh/telnet

[Andrew DeFaria]

I have Cygwin installed at home. I used to telnet to my home machine and 
it would say:

Last login: Fri Aug 23 12:02:56 2002 from <ip address>
$

I have since turned off telnet and switched to ssh. I still get that 
same line echoed out about when I last logged in. Cool, except it still 
says Fri Aug 23th! IOW telnet somehow updated something so that that 
last logged in date would be correct. Apparently ssh isn't updating 
anything. Is this a bug? (Though admittedly a minor bug).

Ah, I'm running Cygwin's sshd as a service.

The parameters passed are: /usr/sbin/sshd -D and CYGWIN is set to ntsec 
in the environment.

I run bash. The shell runs OK. Note that this last login thing happens 
before bash is started:

$ ssh andrew@defaria.com
andrew@defaria.com's password:
Last login: Fri Aug 23 12:02:56 2002 from 206.184.204.2
Starting /etc/profile...
Ending /etc/profile...

Not for my account!

Well who didn't use to work all that good in eariler versions of Cygwin 
but appears to be working better now. Here's what I get:

who /var/log/wtmp | tail 
Andrew   tty4     Dec  9 15:12
Andrew   ftp1828  Dec  9 15:19
Andrew   ftp3884  Dec  9 15:20
Andrew   ftp2520  Dec  9 15:23
ftp      ftp3896  Dec  9 16:11
ftp      ftp4068  Dec  9 16:11
Andrew   tty4     Dec  9 18:19
Andrew   tty5     Dec  9 18:19
Andrew   tty4     Dec  9 18:40
Andrew   tty5     Dec  9 20:01

So I would expect that the last login should say something liek Dec 9!

Hmm what command does your ssh-deamon fire up on the 'remote' machine,
either you have to tell your shell that it should act as "login", or
maybe you even have given it the silent switch.. 

Which shell do you run, and so on? 

Could it be something like ash in /etc/passwd is used..

Re: ssh/telnet

[Abraham Backus]

After checking things out a little more, it looks like "last logged in" type
of data is in your wtmp database, which on my system is /var/log/wtmp.  This
appears to be a log/history of past logins.  To view the data in here, try
the following command:
$ who /var/log/wtmp

Otherwise, I'm at a loss about what's happening on your system :)

I believe that this information is stored in the utmp database, which
appears to be in /var/run/utmp (a binary file) on my installation.  If you
type the "who am i" command, it gives the information from utmp.  There are
probably some tools for displaying what's in this file in a textual/readable
format.  Anyway, does the output of "who am i" give the same information as
what you are getting or is it more accurate?

I did this last night. I'm now on Cygwin 1.3.17 and have openssh 
3.5p1-2. I run ssh as a service and am on Windows XP SP1. Still see Fri 
Aug 23rd as the last login date. Where is this last login date stored? 
How is it updated?

Andrew,
I tried with sshd running as its own NT service, and again with it running
under inetd and my "last logged in" gets updated appropriately.

Cygwin DLL verion 1.3.17
openssh version 3.5p1-2
Windows 2000 SP2

Try updating your cygwin packages by running cygwin setup.exe and see if
that remedies your troubles.
