If you have a profile that used to work and is no longer working for you this might help… or not… The message “Remote peer is no longer responding” is used on more than one failure scenario.
Increase the log level on /etc/opt/cisco-vpnclient/vpnclient.ini:
[main]
BinDirPath=/usr/local/bin
EnableLog=1
[LOG.IKE]
LogLevel=15
[LOG.CM]
LogLevel=3
[LOG.CVPND]
LogLevel=3
[LOG.XAUTH]
LogLevel=3
[LOG.CERT]
LogLevel=3
[LOG.IPSEC]
LogLevel=15
[LOG.CLI]
LogLevel=3
[LOG.FIREWALL]
LogLevel=15
[LOG.PPP]
LogLevel=1
[LOG.DIALER]
LogLevel=1
[LOG.GUI]
LogLevel=1
Now Run:
# ipseclog ipseclog.txt &
Cisco Systems VPN Client Version 4.8.02 (0030)
Copyright (C) 1998-2007 Cisco Systems, Inc. All Rights Reserved.
Client Type(s): Linux
Running on: Linux i686 #1 SMP Wed Feb 11 23:58:12 EST 2009 i686

#
And now try connecting again.
After it fails check /var/log/ipseclog.txt and try finding DEL_REASON_PEER_NOT_RESPONDING.
Then if the profile you’re using has EnableNAT=1 try changing to EnableNAT=0 and try connecting again.
This solved the problem for me.
If you still have the problem try also restarting your Internet connection or the network service (Fedora):
# /etc/init.d/network restart

smachadoLinux, Shell
Say you start a process and you forget to add the & character at the end of the line to send it to the background. You don’t need to restart the process if you’re using bash (and probably other shells – check the documentation of the one you’re using).
To send the running process to the background so that you get the shell prompt back to enter more commands you have to press CTRL+Z while the process is running. The process will be temporarily suspended until you send it to the foreground with the bg [jobspec] command.
Let’s see an example:
[root@localhost log]# tail -f cron
Feb 26 11:01:01 localhost CROND[5731]: (root) CMD (run-parts /etc/cron.hourly)
Feb 26 12:01:01 localhost CROND[5743]: (root) CMD (run-parts /etc/cron.hourly)
Feb 26 13:01:01 localhost CROND[5836]: (root) CMD (run-parts /etc/cron.hourly)
Feb 26 14:01:01 localhost CROND[6097]: (root) CMD (run-parts /etc/cron.hourly)
Feb 26 15:01:01 localhost CROND[6132]: (root) CMD (run-parts /etc/cron.hourly)
Feb 27 04:26:15 localhost crond[2844]: (CRON) STARTUP (1.2)
Feb 27 04:26:16 localhost crond[2844]: (CRON) INFO (running with inotify support)
Feb 27 04:26:20 localhost anacron[2912]: Anacron 2.3 started on 2009-02-27
Feb 27 04:26:20 localhost anacron[2912]: Will run job `cron.daily’ in 65 min.
Feb 27 04:26:20 localhost anacron[2912]: Jobs will be executed sequentially
^Z
[1]+ Stopped tail -f cron
[root@localhost log]# jobs -l
[1]+ 4107 Stopped tail -f cron
[root@localhost log]# bg 1
[1]+ tail -f cron &
[root@localhost log]# jobs -l
[1]+ 4107 Running tail -f cron &
[root@localhost log]# fg 1
tail -f cron
^C
[root@localhost log]# jobs -l
[root@localhost log]#
As you see when you press CTRL+Z (or ^Z) the process is suspended (stopped). You can see the list of jobs and their state by running jobs -l. This job was given the number 1. We can then send it to the background with bg 1 or bring it back to the foreground with fg 1. At the end I kill the process by pressing CTRL+C (^C).
You can stop the job with ^Z and then send it to the background using bg with no additional arguments. Actually you can use the character % as a job name. Let’s see the following example:
# tail -f test1
line 1
line 2
^Z
[1]+ Stopped tail -f test1
# %1 &
[1]+ tail -f test1 &
# jobs -l
[1]+ 3855 Running tail -f test1 &
# tail -f test2
file 2 line 1
file 2 line 2
^Z
[2]+ Stopped tail -f test2
# %% &
[2]+ tail -f test2 &
#
# jobs -l
[1]- 3855 Running tail -f test1 &
[2]+ 3857 Running tail -f test2 &
# %-
tail -f test1
^Z
[1]+ Stopped tail -f test1
# jobs -l
[1]+ 3855 Stopped tail -f test1
[2]- 3857 Running tail -f test2 &
# kill %1
[1]+ Stopped tail -f test1
# kill %2
[1]+ Terminated tail -f test1
# jobs -l
[2]+ 3857 Terminated tail -f test2
# jobs -l
The + flag on the output of jobs -l indicates the current job and the – flag indicates the previous job. The %% and %+ names refer to the current job while %- refers to the previous job. So instead of fg 1 you can use %1. And instead of bg 1 you can use %1 &. And so on…
