reflection client IP
Some of the clients login to my VMS server using reflection client. When I want to see decnet or tcp/ip IP of connecting client using sys$rem_node or other logicals, I could not find any info relating to remote node id.
How can I learn the remote id of clients connecting via reflection

Re: reflection client IP
"show users /full" gives me only the terminals of reflection clients like:
user1 host1 _FTA354: 206D81E7 FTA354:
user1 host1 _FTA355: 206B11EA FTA355:
user1 host1 _FTA357: 206B4024 FTA357:
Is it possible to learn remote id from these info?

Re: reflection client IP
If that is the case, then I don't believe there
is any "easy" way to get the information you
want.

Re: reflection client IP
$! When NAT is in place, the PC can not deliver the ip address.
$! We will look it up ourself.
$ rem_node=""
$ show proc/out=sys$login:pc_sm_dev.tmp
$ open/read x1 sys$login:pc_sm_dev.tmp
$r1:
$ read/end=e x1 x_rec
$ if f$loc("Devices allocated:",x_rec) .ge. f$len(x_rec) then goto r1
$ bg=f$el(2," ",f$ed(x_rec, "compress"))
$! ucx will open the file in append, so delete it first !!!
$ if f$sea("sys$login:pc_sm_ip.tmp") .nes. "" then del sys$login:pc_sm_ip.tmp.*
$ def/us sys$output sys$login:pc_sm_ip.tmp
$ ucx show dev 'bg'
$ open/read x2 sys$login:pc_sm_ip.tmp
$ read/end=e x2 x_rec
$ read/end=e x2 x_rec
$ rem_node=f$extr(55,15,x_rec)
$e:
$ if f$tr("x1") .nes. "" then close x1
$ if f$tr("x2") .nes. "" then close x2
$ return

Re: reflection client IP
I get the bg device out of show proc.
Then I search for it in the ucx show dev listing.
I use this when a rsh comes in and requests to start X with output directed to the PC.
When NAT is in place, the PC doesn't know what address it has. So, we have to search for it.
Not yet tested with SSH.

Re: reflection client IP
When I "show proc", it gives "Device Allocated" as:
Devices allocated: SERVER1$TNA4074:
However, when "tcpip show dev", all "device sockets" starts with "bgXXXX""".
Therefore, I can not correlate tnaXXXX devices and bgXXXX devices

Re: reflection client IP
You may try:
$ TELNET
TELNET> SHOW DEVICE TNAxxx

Re: reflection client IP
you may also try to set the appr. TCPIP service to /LOG=(LOGIN,LOGOUT). Login/logout is then recorded in the OPERATOR.LOG file.
Example:
$ TCPIP
TCPIP>DISABLE SERVICE TELNET
TCPIP>SET SERVICE TELNET/LOG=(LOGI,LOGO)
TCPIP>ENABLE SERVICE TELNET

Re: reflection client IP
Processes connected to a FTA device do not display any VTA, TNA, BG or other device as allocated, only the FT device.
Using SDA you can find out which WSA device is open, and then use SHOW DISPLAY WSAnn: to find the ip address of the PC.
Something like:
$ pipe write sys$output "show proc/chan/id=''p1'" | -
anal/sys | search sys$pipe wsa | -
( read sys$pipe line ; -
wsa_dev = f$element(3," ",f$edit(line,"trim,compress")) ; -
show display &wsa_dev )
