another c++ q (with specialization and inheritance )

[Erez D]

i am having problems compiling the following code:


#if 1
template  class c1 {};
template  class c2 : public c1 { public: c2(T &a); };
#else
template  class c1;
template  class c2;
#endif

template <> class c1
{
int m_a;
public:
c1():m_a(0) {};
c1(int a):m_a(a) {};
c1(int &a):m_a(a) {};
void set(const int a) {m_a=a;};
const int get(void) const {return m_a;};
c2 gen_c2(int a)
{
c2 ret(a);
return ret;
}
const c1 &operator=(const c1 &other) {set(other.get());
return *this;};
};

template <> class c2 : public c1
{
public:
c2(int &a):c1(a) {};
};

int main()
{
c1 a;
c2 b=a.gen_c2();
}
===
if i compile it, i get:
file.cpp:27: error: specialization of ‘c2’ after instantiation

if on the other hand i change the #if 1 to #if 0, i get:
file.cpp: In member function ‘c2 c1::gen_c2(int)’:
file.cpp:20: error: return type ‘struct c2’ is incomplete

It would seem to me that this line instantiates c2, so that

template <> class c2 : public c1
{
public:
c2(int &a):c1(a) {};
};

is an attempt to specialized a class that has already been instantiated 
from the generic template. The compiler has no way to go back and change 
the storage size for c2, which it already needed to know when 
compiling the lines above.


Try to have gen_c2 return a pointer to c2. That may resolve the 
problem.

ssh from 012 cable to server in US fail

[Rami Addady]

Hi,


I have weird problem , staring this morning I can't ssh to a server in 
US,  from some computers that connect to the Internet using 012 cabels.


But if I'm ssh to server in 012 farm and then from it to the US server 
is work fine!


I called 012 technical support but they didn't  help me.


It's not a FW issue because the ssh session start.

When I try to ssh it start and after some time fail , here is debug session.


ssh -v -l user 111.111.111.111

I can't write c2 first as it is derived out of c1
I can't write c1 first as it has a function that returns c2
if i use forward declaration (like i did), i get "specialization after
instanciation"

i am sure that there is a solution to this.
but i don't know what it is.

Try to have gen_c2 return a pointer to c2, and place the actual 
function body definition after the definition of c2.


If that fails, have gen_c2 return a pointer to c1. As c1 is a 
public parent of c2, it should amount to almost the same thing.


In any case, having a child function return a copy of a parent class is 
bad OO design.

So you can look at the server logs and see what went wrong. You can also
try and run it with '-v' to add verbosity there too. If you do, first
try it on a local machine to make sure you do not kill it accidentally.

I have no idea re the actual problem.

Can you provide the server logs? (The connected site)
It can easily shed light on the subject.
On RHEL the log file in interest is /var/log/secure.

Hi,



Can you provide the server logs? (The connected site)


There are no new entry in /var/log/secure



ou can also try and run it with '-v' to add verbosity there too.



The -v output can be found in my first post

Re: ssh from 012 cable to server in US fail

[Tomer Cohen]

Hi,

I had the same issue yesterday evening (012, cable). After few hours I
periodically tried, I was able to access the machines (one is located in
Dreamhost, the other at sourceforge.net), but very slowly and with sudden
disconnections after about one minute of each connection.

Re: ssh from 012 cable to server in US fail

[sara fink]

Please follow these steps:

1. I will highly suggest to launch wireshark when you try to ssh. If you see
a RST, I won't be surprised at all.  You may see a RST that comes from your
ip. Don't be surprised.

2.  You must understand the following thing: they have clients rank A and
clients rank D. from the farm it is possible to ssh (client rank A). from
work/home directly you are client rank D. Take in consideration that you ssh
to usa. you waste their bandwidth.

3. try to ssh to the usa server from other server that doesn't use 012.

4. try to ssh to a server in israel and compare.

5. Try to run the following command tcptraceroute -v  22
and see where it gets stuck (timing).

6. I smell a Deep Packet Inspection. I will be very happy to be proved
wrong.

these all sound annoyingly like the "adventures" a friend of mine had
when connecting to my server from china, including obvious
man-in-the-middle attacks, such as each time hׁ” tried to connect, the
"server" would display a different host key.

If the state of Israel has started building a "great firewall" they are
both doing it wrong, as well as against the current law. very sad :-(

Re: another c++ q (with specialization and inheritance )

[Oleg Goldshmidt]

Erez, 

None of this is Linux-specific, maybe you should find a good C++
forum, e.g., comp.lang.c++.moderated? However, since you asked, here
is an explanation.

You should understand the difference between definition and
declaration, and also that if you define a template, then instantiate
an object of the templatized class, and then try to specialize the
template it will look as a redefinition of the class to the compiler.

See below.

Erez D  writes:

> i am having problems compiling the following code:
> 
> #if 1
> template  class c1 {};
> template  class c2 : public c1 { public: c2(T &a); };

This is a *definition* of class c2. Below you attempt to redefine
it (rather than specialize it - this is because you instantiate it
before specializing), and the compiler complains.

> #else
> template  class c1;
> template  class c2;

This is a forward declaration of class c2. It is declared but not
yet defined. When this preprocessor branch is active the definition
below is OK.
  
> #endif
> template <> class c1

>     int m_a;

The first const is ignored since you are not returning a const
value. The trailing ";" is also ignored (a recurring thing in your
code). But this is irrelevant for the question at hand...
 
>     c2 gen_c2(int a)
>     {
>     c2 ret(a);

This is where you *instantiate* an object of type c2, so you
cannot specialize the template later, as the compiler tells you.

The cure also is logical. Declare the method here, and write the
definition *after* specialization, i.e., put

c2 c1::gen_c2(int a)
{
c2 ret(a);
return ret;
}

immediately before main().
 
>     return ret;
>     }

> public:
>     c2(int &a):c1(a) {};

I don't think this will compile (when you get to it) - c2 does not
have a c1 member, which is what this notation exists for. Instead,
c1(a) will be automatically called as the base class constructor, so
you only need

  c2(int &a) {}

if I understand your intention correctly.

There is no c2 c1::gen_c2(void). There is only c2
c1::gen_c2(int).

This is a precise statement - you only had to look for instantiation
in your code - see above.

Correct again - you have declared, but not defined c2.

Hope it helps,

The compiler and Shachar... I was not attentive enough reading his
post, focused on the suggestion to return a pointer... He diagnosed
the problem perfectly, the solution is in my post.

Re: ssh from 012 cable to server in US fail

[Shay Ohayon]

Hello folks,

I am also connected through 012 Cables (HOT) and am unable to connect
(ssh) to servers in The Netherlands and US. Also tried talking to tech
support and they didn't even had a clue.

Please update if any of you got a solution (or any support from any of
the companies).

For the record, I am connecting through LPNS (directly receives dhcp
address from the modem - aka "le lo haigan")

best regards,
shay

Trial and error: what if you use a different port number for the server?

For testing:

  /usr/sbin/sshd -D -p 1234
