DESCRIPTION

10       Xconvers  is a 'split screen' convers client for X.  After a connection
11       has been made, the top section of the  main  window  will  display  the
12       server response, you can type your text in a one-line transmit entry.
13
14       Incoming  messages are colorized for every user when logged into a con‐
15       vers server.

TIPS

19       Xconvers uses SO_KEEPALIVE on the  connected  port.   The  SO_KEEPALIVE
20       option  causes  a packet (called a 'keepalive probe') to be sent to the
21       remote system if a long time (2 hours by default) passes with no  other
22       data  being sent or received. This packet is designed to provoke an ACK
23       response from the peer. This enables detection  of  a  peer  which  has
24       become unreachable (e.g. powered off or disconnected from the net).
25
26       This  keepalive  time can be changed at runtime from the /proc filesys‐
27       tem. You might be interested in setting this  time  much  shorter,  for
28       example when using xconvers over AX.25 with an unstable network:
29
30       echo "900" > /proc/sys/net/ipv4/tcp_keepalive_time
31
32       will send an ACK packet every 15 minutes.
33
34       When using xconvers behind a masquerading firewall, you might encounter
35       timeouts. The server you are connected to will reset the connection  if
36       you type something after being idle for more than 15 minutes. The solu‐
37       tion for this is changing the timeout value for  your  masqueraded  TCP
38       connection:
39
40       ipchains -M -S 14400 0 0
41
42       The  number  14400  has  set  the  TCP  timeout to 4 hours. When typing
43       'ipchains -M -L', you will see an expire timer  which  counts  down  to
44       zero.
